Amazing dashboard, real-time data, and straightforward licensing
Pros and Cons
  • "The dashboard is amazing. Out-of-the-box dashboard is very good. It is very user-friendly."
  • "Its performance can be better. Sometimes, it takes longer when we do queries."

What is our primary use case?

We are using it for our SOC. We integrated it with our SOC.

How has it helped my organization?

We have had a couple of benefits. We are using it as a SIEM. We do log extraction and analyze them. We also use reporting and dashboards. We are using it for security assessment. It is very helpful for us to be able to see what it has been like. Based on the incidents, we can take measures to cover any gaps.

Our security posture has definitely improved since we started using Splunk Enterprise Security. We are scaling it in stages. We are not yet using it at an optimum level. We are using 50% to 60% of it. Based on the analysis that we are doing, our security posture has definitely improved.

The end-to-end visibility that it provides is very important for any organization. It is the right tool to get end-to-end visibility. We get 360-degree visibility.

Like most organizations, we are moving to the cloud. We have a hybrid environment. We have a SaaS, PaaS, and on-prem environment. It is a very good tool for identifying security incidents. There are statistics, and we can go back and forth to see exactly what happened.

Splunk Enterprise Security has improved our organization’s ability to ingest and normalize data.

It is a real-time tool. What I like about it is how they are able to bring all the logs into a single dashboard. We can quickly get what we are looking for. We have queries. That is amazing.

Splunk Enterprise Security provides us with the relevant context to help guide our investigations. We are not using it completely, but based on our usage, it is up to our expectations.

Splunk Enterprise Security has helped reduce our mean time to resolve. Previously, if an incident used to take us an hour, it now takes us a few minutes.

What is most valuable?

The dashboard is amazing. Out-of-the-box dashboard is very good. It is very user-friendly. It is out of the box. With a few clicks, the dashboard is there.

What needs improvement?

Its performance can be better. Sometimes, it takes longer when we do queries.

Their support can also be better.

Quickly identifies threats, secures our environment faster, and reduces alert volumes
Pros and Cons
  • "The Splunk queries are valuable."
  • "I would like the ability to view logs for specific instances and not have to pull the logs for the entire Cloud environment in Splunk."

What is our primary use case?

We use Splunk Enterprise Security to teach our students about security awareness in a more positive way. We can show them how these tools work and the benefits they bring. This will help them understand the importance of using Splunk Enterprise Security, not just for our clients, but for ourselves as well.

How has it helped my organization?

The Splunk dashboards are user-friendly.

I would rate Splunk's threat topology an eight out of ten. The threat topology provides a complete map so we can investigate security incidents quickly.

To effectively utilize Splunk for malicious activity analysis, a comprehensive understanding of the different event types and their functionalities is crucial. This involves examining specific events associated with potential malware, such as changes in system behavior. By gaining clear visibility into these events, we can identify the malware's goals within our environment and stop it.

Splunk helps us detect threats within three minutes.

We realized the benefits of Splunk within eight months. Splunk Enterprise Security helped secure our environment faster than other security solutions.

Splunk has helped reduce our alert volume.

What is most valuable?

The Splunk queries are valuable. There are a lot of query options available in Splunk compared to Sumo Logic.

What needs improvement?

It is difficult to monitor multiple cloud environments using Splunk.

I would like the ability to view logs for specific instances and not have to pull the logs for the entire Cloud environment in Splunk.

As the number of environments monitored by Splunk increases, the resource demands also grow, potentially slowing down the system.

Splunk's threat intelligence system gets a seven out of ten. There are frequent delays in updates, which can take up to three months for Splunk to make available.

For how long have I used the solution?

I have been using Splunk Enterprise Security for one year.

What do I think about the stability of the solution?

I would rate the stability of Splunk Enterprise Security ten out of ten.

The resilience is good. I have not faced any issues.

What do I think about the scalability of the solution?

I would rate the stability of Splunk Enterprise Security nine out of ten.

How are customer service and support?

The technical support team is good.

Helps improve our incident response, is robust, and user-friendly
Pros and Cons
  • "The most valuable feature is the custom dashboard feature."
  • "Splunk's ability to analyze malicious activities scores an 8 out of 10, but there's room for improvement. By analyzing emerging patterns, Splunk could identify and predict potential threats more effectively."

What is our primary use case?

We currently use Splunk Enterprise Security for security monitoring. Previously, we relied on AWS native monitoring tools. In that setup, logs were forwarded to a Splunk dashboard which was also used by our L1 and L2 support teams to evaluate incoming support cases.

How has it helped my organization?

CloudWatch, the native AWS monitoring tool, offers limited metric detail and a complex navigation experience across different data streams. In contrast, Splunk empowers us to create custom dashboards. This allows our team to quickly access the relevant dashboard and perform root cause analysis during an incident, streamlining our response process. This is how Splunk has been instrumental in enhancing our efficiency.

Splunk dashboards significantly improved our incident response by providing a single view of all relevant information. This allowed us to quickly identify and address issues. Additionally, Splunk's customization capabilities enabled us to tailor dashboards to focus on the specific metrics most critical to our operations. As a result, we could easily create dashboards highlighting high-priority metrics. Splunk's real-time data ingestion allowed for near-instantaneous monitoring. Logs generated in AWS were pushed to Splunk almost immediately through a collector. This enabled us to use the dashboard to investigate these logs in real-time. Furthermore, integrated identity and access management facilitated easy sharing of dashboards with other users.

Splunk itself may not have directly improved collaboration on security issues. However, in the event of an incident requiring investigation by a senior security professional, Splunk simplifies the process. L1/L2 teams and support engineers can easily point to the relevant dashboard connected to the issue. Additionally, these dashboards provide valuable features for further investigation, post-mortem analysis, or what they might call building the analysis or post-mortem report.

Splunk has been helpful for customers in resolving a wide range of issues. Whenever a problem arises, IT staff can quickly identify the root cause using Splunk. This allows for faster issue resolution, which in turn helps businesses retain customers and maintain their overall value.

What is most valuable?

The most valuable feature is the custom dashboard feature.

Splunk is robust and user-friendly.

What needs improvement?

Splunk's ability to analyze malicious activities scores an 8 out of 10, but there's room for improvement. By analyzing emerging patterns, Splunk could identify and predict potential threats more effectively.

For how long have I used the solution?

I have been using Splunk Enterprise Security for three years.

What do I think about the stability of the solution?

I would rate Splunk Enterprise Security's stability 9 out of 10. 

What do I think about the scalability of the solution?

Splunk Enterprise Security was able to meet our scalability needs.

Which solution did I use previously and why did I switch?

We previously used native cloud monitoring. Now, we supplement it with Splunk to benefit from its additional features.

How was the initial setup?

While the initial deployment was simplified by the availability of Splunk connectors in the public cloud, additional effort was required. We had to write the infrastructure as code, build the connector itself, pull the logs, and push them to the Splunk endpoint. These steps, including connection and configuration integration, would equate to moderate effort for a single person.

What's my experience with pricing, setup cost, and licensing?

For those considering a SIEM solution but prioritizing affordability, Splunk is a strong contender. My experience using Splunk for several years has been positive, with minimal glitches. Additionally, its user-friendly GUI allows new users to contribute immediately. Splunk is also feature-rich, offering a wide range of functionalities out-of-the-box. However, remember that quality often comes at a cost. Considering these factors, Splunk emerges as a cost-effective solution.

What other advice do I have?

I would rate Splunk Enterprise Security 8 out of 10.

Splunk did not help us reduce our alert volume because it was not integrated directly for alerting. It was integrated for monitoring. The alerting happened from our native cloud.

Splunk is self-sustainable and doesn't require maintenance.

We have never needed to contact Splunk support because their documentation is good enough for us to resolve the issues ourselves.

Splunk Enterprise Security is a stable, feature-rich, and user-friendly product with a well-designed graphical user interface.

Which deployment model are you using for this solution?

Good monitoring and visibility with helpful threat detection capabilities
Pros and Cons
  • "The solution helped reduce our alert volume."
  • "When we do a rollout from the server or host or anything, we'd like to see more automation. It would save us time."

What is our primary use case?

I have worked in a couple of areas of Splunk. Initially, I was part of a monitoring team that used it for security information. I used to monitor security alerts which we used to get on Splunk, which was based on the use cases and we set up specific rules for it. Currently, I am part of the administration of Splunk. Now I onboard different log sources to Splunk. We pass over the logs so that it can be used for the security team.

How has it helped my organization?

It helps with security and making sure our infrastructure is compliant. It also allows reporting to be in one centralized location. We can monitor the security logs effectively. It really helps as a cybersecurity element for the company infrastructure to protect us from attacks.

It is quite reliable in terms of data. We have a good amount of licenses currently and find it to be very flexible. It can handle and pull up any amount of data.

What is most valuable?

Splunk is very fast and user-friendly as well. The UI and design is user friendly. It is easy to understand. 

We can do a lot of things on Splunk. We can integrate a lot of other applications on Splunk. And that can be used for day-to-day security operations. It is easy to use, easy to implement, and it is fast. It is reliable.

Our organization monitors multiple cloud environments. We monitor all the infrastructure and cloud environments of clients.

It is easy to monitor multiple cloud environments with Splunk. You have to get clients onboarded to Splunk first, and then the monitoring part comes last. We have a couple of things that have to be done before the security team starts monitoring. For example, we install the agents and set up the hosting. We get the data from the host, we pass it. It is quite a lengthy process. It is easy, however, we have to do it very carefully and cautiously.

Splunk Enterprise Security provides visibility into different environments.

The solution's insider threat detection capabilities for helping our organization find unknown threats or anomalies in behavior are good. We have multiple security frameworks. For example, we have micro frameworks. There are different sets of rules. We set it. What Splunk does internally is just match the incoming logs. Based on the rules that we have set, it will match with the incoming logs. If it matches, then it will generate alerts for the security team. Based on that, we can identify if there is a potential threat trying to get into the company or internal infrastructure. 

The actionable intelligence provided in Splunk Enterprise Security is good. 

It will help us to automate things and can handle certain items on its own. It will just investigate, remediate, and close the necessary alert. If it is beyond Splunk's capability, then an investigation team will be involved in it. 

I have used the threat topology and attack framework feature, however, now I am more of an administrator.

Splunk Enterprise Security is good for analyzing malicious activities and detecting breaches. There are a couple of other tools as well, which do the same thing. However, with Splunk, it's very easy to work with the dashboard and do search queries. You can easily look through the logs via Splunk UI.

The solution helped reduce our alert volume. It will just minimize the false alerts, and just post positive alerts. It's likely reduced false alerts by 60%. A lot is automated now and that helps cut down on manual work.

The solution has helped to speed up our security investigations. Once again, the automation will speed up the process of investigation. It saves a lot of time for analysts as it allows them to see the initial data. If a team has multiple alerts, it will take them time to go through and check everything. However, Splunk does the initial investigation for analysts and will escalate to analysts as needed. It might have reduced security investigations by 80% compared to earlier versions. 

What needs improvement?

When we do a rollout from the server or host or anything, we'd like to see more automation. It would save us time. We wouldn't have to write anything. We would just like the raw log automation.

For how long have I used the solution?

I've been using the solution for three years now. 

What do I think about the stability of the solution?

It is a stable product.

What do I think about the scalability of the solution?

There are two types of users: the administrators and then the users where the logs are coming from. We have about ten to 15 administrators working directly with Splunk. Overall, there may be more than 1,000 end users we get logs from.

The solution is scalable. In terms of data, it's very flexible. 

How are customer service and support?

Technical support is good.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I've used other solutions in the past. We previously used
ArcSight Enterprise Security Manager (ESM). It was older and very slow. Comparatively, Splunk is very fast and it has a better UI.

How was the initial setup?

The initial setup was easy. It was not complex. I didn't do the implementation on my own. The deployment times vary. There are many moving parts, such as approvals that need to be taken into consideration. 

We get logs from various sources from various clients.

It does require a bit of maintenance. It requires, for example, server upgrades and patching. 

What's my experience with pricing, setup cost, and licensing?

I can't comment on pricing. I don't take care of that aspect. 

What other advice do I have?

I'm a customer and end-user.

I'd recommend the solution to others and invite them to test the service first on the infrastructure they have. It's a very valuable product to have.

I'd rate the solution nine out of ten.

Which deployment model are you using for this solution?

Correlation searches are very helpful, and it has amazing stability and fantastic documentation
Pros and Cons
  • "The correlation searches are most valuable just because we are able to do things like RBA."
  • "The UI could be better. This is applicable to Splunk in general. I know that a lot of people who get their hands on Splunk are hesitant to use it just because they find it overwhelming. There are a lot of options."

What is our primary use case?

We essentially use Splunk for our Security Operations Center (SOC). All of the notables that we create for the SOC are done in Splunk Enterprise Security. It is our SIEM.

How has it helped my organization?

I cannot put a value on it, but it has been pretty good. Previously, we used to use ArcSight. I used to do incident response when I first joined the SOC, and there were times when I used to sit down and run a search right at the start of my shift, which is at 7 AM, and I used to hope that it would be run by the end of the shift at 7 PM. I used to hope that it would run in 12 hours and not time out. When we got Splunk, it was a game changer. It took seconds to a minute depending on how intense the search was.

We monitor multiple cloud environments. It is easy to ingest data in Splunk. Based on what I hear from our customer success manager, he has customers who have issues ingesting logs, but for me, it is one of the easiest things ever. Their documentation is fantastic.

Splunk Enterprise Security has end-to-end visibility into our cloud-native environments. It is very important for us. When we first got cloud, it was like the Wild West. Anyone could spin up their own cloud infrastructure, and we would not know about it. It was public. We did not know what they were doing with it. Now, we have a better grasp and understanding of what is out there, so Splunk makes it easy for us to keep track of our endpoints that are public-facing.

Splunk Enterprise Security has helped reduce our mean time to resolve. As compared to ArcSight, it has saved at least three to four hours per incident. We utilize a SOAR platform. We do not use Splunk SOAR. We use a different SOAR platform, but with the combination of Splunk Enterprise Security and our SOAR platform, we are able to cut down our mean time to resolve. The time saved varies depending on the case. A normal case would probably take less than ten minutes per investigation. A critical P1 case would take more time, but a normal day-to-day case would take less than ten minutes for our analysts to do their work. A normal case is where a user clicks on a phishing link in an email, or your EDR solution says something happened and there is a threat actor in your environment moving laterally trying to access data.

What is most valuable?

The correlation searches are most valuable just because we are able to do things like RBA. One of the things that we started pretty recently is our insider threat program, and it has been pretty good, especially using RBAs as our framework for the insider threat.

What needs improvement?

The UI could be better. This is applicable to Splunk in general. I know that a lot of people who get their hands on Splunk are hesitant to use it just because they find it overwhelming. There are a lot of options. If you open Google.com, you just have a search bar. You just search and hit "go," but when people look at Splunk, they are just overwhelmed. I see that with our analysts. Even after training, if they do not use it every day, which they should be doing, they kind of lose it.

Its learning curve is a bit steep. It is hard for users to use it. For individuals who know how to use it, it is fantastic. It is great. For example, if you are a Splunk Cloud customer, and you had an outage or there is a maintenance window, those individuals who are power users would know immediately when it happens or they would know that there is a maintenance window coming up because they are the experts. They are the SMEs on their teams, and they are the ones creating value using Splunk. Individuals who do not know how to use it are intimidated.

For how long have I used the solution?

We have been using Splunk Enterprise Security since 2017. It has been about six years.

What do I think about the stability of the solution?

Its stability is amazing. It is always up. It is fantastic.

What do I think about the scalability of the solution?

It is awesome. When we first purchased Splunk Cloud, our ingest rate was about one terabyte or one and a half terabyte. We moved from the ingest-based license to the workload-based license three or four years ago, and now, we ingest about 10 to 12 terabytes. It is handling that just fine as if nothing has changed.

How are customer service and support?

I would rate their support a six out of ten because there are times when someone picks up a support case, but they do not know what they are doing. I have to guide them. It is like, "I have already done the research. This is what needs to be done. There you go. Do it." I expect a little bit more from support in terms of having the knowledge upfront.

How would you rate customer service and support?

Neutral

Which solution did I use previously and why did I switch?

We had on-premises ArcSight. We had one guy run it for our enterprise. Our enterprise has roughly over 130,000 people. We are a global company, and we had one guy run the entire infrastructure. We could tell when he took days off because it would not work. When we moved to Splunk, we went to Splunk Cloud immediately. We were one of the first Splunk Cloud customers or one of the bigger ones. That is what I was told when we made the switch.

I do not know whether we have seen any cost efficiencies by switching to Splunk Enterprise Security because I was not there during the ArcSight days per se. I was there at the very tail end, but I would assume that we have seen cost efficiencies just because ArcSight was only used by the security team, whereas Splunk is used enterprise-wide, not just by the security team. It should be cheaper for us. The value is there. It is cross-functional.

How was the initial setup?

I was not involved in its deployment.

What was our ROI?

Its time to value was about a year. It took us about a year because back in 2017, we were making that conversion from an on-premise ArcSight deployment to a Splunk Cloud deployment. We had to make sure that everything that was being sent to ArcSight was sent correctly to Splunk. We had to make sure that everything was in a common information model format and that we could rebuild the content.

What's my experience with pricing, setup cost, and licensing?

Splunk Enterprise Security is cheaper than competitors, but I do not know whether it is just our contract. 

Everyone says that Splunk, in general, is expensive. I have talked to many peers within our industry, and I know a lot of individuals who are moving away from Splunk just because of the price. That is one of the reasons why we are looking at other competitors to see if anyone is doing something better than Splunk and has a cheaper rate.

Which other solutions did I evaluate?

I have looked at other competitors. We recently looked at CrowdStrike's LogScale solution. It feels like Splunk to me. I cannot say how we would reproduce what we have done in Splunk on the infrastructure side or backend. Our environment is uniquely different. Technically, I am the only person who runs Splunk for our entire organization, similar to the way the previous person ran ArcSight for the organization. If I were to compare apples to apples, Splunk to me is still number one in that category.

Splunk's community is the biggest benefit. It is so easy to go to Slack and hit someone up. There is a good chance that you will find someone out there who has run into the exact same issue that you are having. Their documentation is fantastic. Because I am the only one who runs it for our organization, it is easy for me just to Google it, find the document, and just follow it. It is as simple as that. It gets a little dicey with XDR and all the other things that are happening in the market, such as using a data lake. Instead of putting our eggs in one basket or using Splunk, we might use something like Snowflake.

What other advice do I have?

I get introduced to new ideas by attending the Splunk Conference. In the year before last, someone did a talk about business email compromises. Within our company, we did something similar, and we did it about nine to ten months before the talk. I listened to the talk to see if we were doing anything different from what they were doing. I found out that we were doing the exact same thing essentially. I thought, "We could have done a talk like this too." These talks are very helpful. For example, they showcased the attack analyzer, and currently, we are looking for an automated online sandbox, just like the attack analyzer. We have been looking at cloud-based sandboxes that are out there. Being able to see it hands-on and how it interacts with Splunk makes it much easier for us to make that decision.

Overall, I would rate Splunk Enterprise Security a nine out of ten.

Has enhanced our organization by offering increased visibility and provides quick search results
Pros and Cons
  • "The most valuable features include agility and Splunk Enterprise Security's ability to quickly search for alerted items, as well as the capacity to create custom alerts using the SQL language employed by Splunk."
  • "Splunk could enhance its services by providing more comprehensive professional assistance aimed at optimizing our investment."

What is our primary use case?

We use Splunk Enterprise Security as the main SIEM system for our operation center. We use it for monitoring detection, and alert management.

We implemented Splunk Enterprise Security to help detect attacks on our network.

How has it helped my organization?

Splunk Enterprise Security is highly flexible, allowing us to create whatever we desire. This exemplifies its inherent power. The visibility it offers is notably robust. We can craft it to our needs and even utilize various frameworks within Splunk, prepackaged for security purposes. We possess distinct applications hosting diverse dashboards, catering to numerous security products, including those from different vendors.

The effectiveness of Splunk Enterprise Security insider threat detection capabilities, aimed at identifying unfamiliar threats, relies on whether we establish alerts based on the rules we formulate. If we construct rules incorporating user behavior criteria, the system functions optimally. It appears that there is an Extended User and Entity Behavior Analytics add-on available, which requires a separate license in addition to the enterprise security license. This add-on utilizes machine learning and encompasses multiple developed use cases. While it has limitations, it effectively serves the specific use cases it is designed for.

The threat intelligence framework within Splunk is also highly potent. We can ingest, link, and integrate external data feeds. Concerning IOCs, there are numerous pre-configured alerts within the system that rely on a feed of undesirable IPs. If one of these IPs triggers any of the alerts, such as those generated by our firewall's traffic logs, and the IP matches the bad IPs in the threat intelligence feed, the system correlates this information. If the flagged IP is detected within our network or appears in our firewall logs, an automatic alert is generated. We simply need to ingest the external feed. Subsequently, if the system identifies the IP anywhere, we will receive corresponding alerts.

I appreciate the new MITRE ATT&CK feature. I believe it's a valuable addition and reasonably priced. It seems the feature has been largely developed through marketing efforts, utilizing the capabilities of Splunk to display the MITRE ATT&CK map and the associated rules. This is important since MITRE ATT&CK encompasses over a hundred techniques. It presents the information to us based on the MITRE ATT&CK framework to illustrate ongoing activities. However, achieving a comprehensive understanding of each technique within the MITRE ATT&CK framework requires significant effort and adjustments.

Splunk Enterprise Security has enhanced our organization by offering increased visibility. If any adverse incidents occur, we are promptly informed. Even without configuring the custom rules, Splunk provides effective out-of-the-box rules that help prevent attacks. Consequently, it effectively halts these attacks. In fact, we have been able to detect and thwart potential attacks in their initial stages. This exemplifies the benefits it provides us.

Splunk Enterprise Security has helped to speed up our security investigations. We are now able to complete our investigations within three or four days. 

What is most valuable?

The most valuable features include agility and Splunk Enterprise Security's ability to quickly search for alerted items, as well as the capacity to create custom alerts using the SQL language employed by Splunk. This makes it a highly potent and versatile solution tailored to both user and company needs.

What needs improvement?

Splunk could enhance its services by providing more comprehensive professional assistance aimed at optimizing our investment. This aspect seems lacking as our expenses increase with higher data connectivity, seemingly without much consideration, as this translates to increased revenue for them. The challenge lies in the fact that we don't always require all the amassed data. Oftentimes, clients are uncertain about their actual data needs. Therefore, if Splunk integrated a service dedicated to system optimization and pricing, focusing on essential monitoring data while eliminating less crucial elements, it could potentially lead to cost savings for the customers. This strategic move would demonstrate their commitment to customers beyond just financial gain. It would highlight their genuine intention to provide support, streamline operations, and maximize the potential of this technology for individuals and their respective companies.

Splunk provides automation for large-scale environments where numerous servers are present. Consequently, efficient management of these servers becomes imperative. Currently, our management server operates using a top-down approach. This involves establishing connections from the main management server to every individual leaf and subsequently, to each lower-level server.

However, this architecture lacks inherent security measures. In the current setup, Splunk employs multiple collectors to gather data. Subsequently, this data is relayed upward, filtered, and then once again transmitted to the main management server. Notably, data traffic consistently flows from external sources toward the central management hub. This design enhances security, as even if a hacker were to compromise or gain control of the management server, their influence would be limited. The data originates externally and travels inwards, preventing unauthorized access to the entire system. 

In contrast, the proposed approach for managing extensive infrastructures situates the management hub at the core. This central position allows us to establish connections from the hub to the various peripheral components, even if they are located on a secure network. However, this configuration carries significant risks. A security breach at the central hub could potentially grant an attacker elevated permissions. This would enable them to compromise the entire network by gaining access to all Splunk nodes within the company. This architecture is vulnerable and has room for improvement.

For how long have I used the solution?

I have been using Splunk Enterprise Security for four years.

What do I think about the stability of the solution?

I would rate Splunk Enterprise Security's stability a seven out of ten. This is because the system lacks built-in protection against certain issues. It alerts us when there are problems in the system, which we then need to address. However, these issues are not always easily fixable, setting it apart from other systems. For instance, sometimes the system slows down while we're working. This can occur when a new alert is implemented, leading to high resource usage and system instability. We are then required to identify and rectify the specific cause of this problem. This might involve disabling or adjusting the alert to ensure it doesn't negatively impact the system's performance.

What do I think about the scalability of the solution?

Splunk Enterprise Security's ability to scale is good. I rate the scalability an eight out of ten.

How are customer service and support?

The technical support is good.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

Previously, I used QRadar, McAfee, and ArcSight. However, Splunk Enterprise Security is a more modern solution. While ArcSight from HP is powerful, it is an older system with limited flexibility and complex architecture. Many companies implemented SIEM systems before Splunk became available. It seems that most large companies might still be using ArcSight, but other competitors have entered the market since then.

McAfee attempted to develop a similar system, but it lacked scalability and was better suited for small businesses rather than larger enterprises. QRadar, on the other hand, remains robust, but it lacks Splunk's flexibility. One of Splunk's notable advantages is its ability to generate alerts and then allow users to enter searches and queries to investigate network activities and log data. This process, known as threat hunting, enables users to conduct specific searches, such as identifying individuals who accessed a particular system and the internet between four and five o'clock on a Friday. Splunk promptly provides the desired results, typically within a few minutes, making it a strong choice for this purpose. Additionally, Splunk Enterprise Security features a highly effective filtering mechanism.

How was the initial setup?

I participated in the planning and implementation of Splunk Enterprise Security, as well as the creation of all rulesets and alerts. I am also configuring it to align with our technical framework.

Individuals who market Splunk Enterprise Security often claim that it can be deployed within half a day, which is quite amusing. While it is conceivable to perform the installation in that timeframe, the real complexity arises when we must establish connections with numerous systems. This involves accessing each system external to our main setup, configuring it, and directing the system to send its logs to Splunk. On the Splunk side, we encounter the need to create parsing mechanisms that allow proper data reading. This entails installing applications capable of correctly parsing the data, and addressing issues where parsing is inadequate. We then proceed to work with the data. Although Splunk provides some pre-configured rules, we also need to develop our own rules to identify specific events and potential attacks. The process of rule creation demands a substantial investment in writing rule sets. Additionally, integrating a threat intelligence framework becomes essential. We aspire to leverage the micro-framework we have established. Splunk Enterprise Security undeniably possesses considerable capabilities. Nevertheless, it necessitates continuous effort to unlock its full potential and achieve ongoing enhancements.

The solution's complete implementation may require up to one year. Throughout most of the deployment, we had a team of two members, occasionally expanding to three.

What about the implementation team?

For the implementation, we used two integrators and Splunk Professional Services.

What was our ROI?

Considering the fact that Splunk Enterprise Security aids in thwarting attackers from gaining access to our environment, I would correlate this with a return on investment.

What's my experience with pricing, setup cost, and licensing?

Splunk Enterprise Security's pricing is high. Larger companies may afford it, but I believe that in the current market situation, where everyone is facing challenges, financial resources are tight. Even stock market tech companies are embracing cost-saving measures. Expenses are now more constrained compared to a few years ago when companies had greater spending capacity. Companies are reluctant to make hefty payments. While Splunk is cheaper than Microsoft Sentinel, QRadar is priced at half the cost of Splunk.

Splunk Enterprise Security's licensing is typically determined by the data throughput we handle. Additionally, they offer an alternative pricing model which involves payment based on CPU usage. This newer model was introduced as a response to Elastic Security. However, Splunk enforces licensing in either scenario. 

What other advice do I have?

I rate Splunk Enterprise Security a nine out of ten.

We do not monitor the cloud environments with Splunk. While we have several cloud environments, we avoid using Splunk for this purpose due to its high cost. To utilize Splunk, it would be necessary to place the Splunk engine in the cloud and gather all the logs from various cloud sources, resulting in substantial expenses due to the large volume of logs. As a result, our primary usage of Splunk is on-premise. Instead, we employ different systems to monitor the cloud, generating alerts through various security mechanisms. These alerts are then processed in Splunk, reducing both data traffic and costs.

Splunk Enterprise Security's capabilities to analyze malicious activities and detect breaches are similar to those of other systems. Its effectiveness depends on the rules we develop within it. To truly maximize its value and tailor it to the organization's needs, a significant amount of additional work and utilization of professional services are required.

The reduction of the alert volume presents a challenge due to the X number of personnel in the security alert center. They can effectively handle only Y alerts per day without experiencing fatigue. When the volume surpasses this limit, they tend to merely open and close alerts without thorough investigation. It's as if they've become weary of the process. Therefore, we must determine the optimal number of alerts per day and adjust the rules accordingly. The primary objective is to achieve a statistically reasonable number of alerts per day. This number should be somewhat higher than the current rate, but not three times greater, as exceeding this threshold would render their efforts ineffective. Conversely, if the number of alerts is too high, the personnel's capacity to take action is undermined, resulting in a lack of meaningful outcomes. Striking a balanced middle ground is imperative. This approach enables us to effectively identify and address crucial matters while ensuring our personnel can thoroughly investigate each alert.

Depending on the goals an organization aims to achieve, if their sole focus is on finding the most economical solution and they do not prioritize comprehensiveness, then QRadar would suffice. However, if they seek instant access to answers, I would recommend Splunk Enterprise Security.

Splunk Enterprise Security is deployed across our entire network.

Maintenance is necessary for the system, and updates are needed periodically. Whenever we acquire a new system, we must connect it to Splunk.

Resilience constitutes a crucial component of Splunk Enterprise Security, contributing significantly to the safeguarding of our system.

I recommend Splunk Enterprise Security for organizations that have the budget, time, and skill to properly utilize the solution. I do recommend paying for Splunk Professional Services.

Excellent data dashboards, visualization effects, and threat detection
Pros and Cons
  • "Recently, Splunk upgraded to version 9.0.02, which includes excellent data dashboards and visualization effects."
  • "We will receive alerts only for the administrators and deployment servers, but not for all servers."

What is our primary use case?

We provide services to our clients as a security operations center and we utilize Splunk Enterprise Security for enterprise security purposes, encompassing various use cases based on client requirements. These include network attacks, malware-related attacks, inbound traffic-related attacks, recurrent activities, web-related detections, internal detections related to root flows, and service account-related use cases.

We are working to secure the enterprise's networks, devices, and infrastructure, as well as enhance overall security. Our goal is to monitor and protect against all types of external cyber-attacks. We will diligently monitor the systems and address any issues at the earliest stage possible.

Splunk Enterprise Security can be deployed both on-premises and in the cloud. We have primarily deployed the solution on Splunk Cloud.

How has it helped my organization?

We utilize Splunk Enterprise Security for monitoring multiple cloud environments. By employing an API, we can deploy various forwarders within Splunk. These forwarders gather logs from diverse cloud sources and other types of sources. Consequently, we have the ability to install an API from the Splunk store, enabling us to seamlessly connect with cloud sources such as CloudWatch, AWS, and other similar platforms. Splunk Enterprise Security offers comprehensive visibility across numerous environments.

Splunk Enterprise Security offers excellent threat detection capabilities to help our organization identify unknown threats. Additionally, we utilize threat feeds that index various anomalies. We have integrated threat intelligence platforms, which provide indicators such as advisories and engagement in case of compromises and attacks. This integration assists us in preventing attacks within our environment. Initially, we can obtain this information through the threat feeds. Consequently, we can restrict and block operating systems either within Splunk itself or through other security tools.

We also utilize threat intelligence. We have access to threat feeds from various sources, such as VPN. The threat intelligence management feature allows us to collect detailed information in the event of a data breach affecting an organization on other websites or within the dark web itself. We receive such information, along with details of any attacks or incidents occurring in different environments worldwide. We can obtain these threat feeds instantly through the cyber news channel mentioned.

The threat topology and MITRE ATT&CK features are integrated, allowing us to obtain the tactics, techniques, and processes necessary to solve any remediation process. By deploying the TTP MITRE ATT&CK framework in any use case, we can acquire a detailed explanation and determine the appropriate course of action to follow. Checking the MITRE enables us to easily resolve and remediate any issues. This helps us address any errors or crashes effectively, by following the simple steps outlined by MITRE. It allows us to easily identify and rectify issues, without the need to involve a senior person if they are unfamiliar with the specific use case. Additionally, it enables us to quickly verify and provide remediation, specifically tailored to the respective team that needs to take action.

Splunk Enterprise Security's ability to analyze malicious activities and detect breaches is advantageous to me. When compared to other tools I have used previously, it involves a straightforward SQL query, allowing me to quickly modify the reports in less than five minutes.

Splunk Enterprise Security has helped us detect threats faster. We can integrate multiple security tools, and we can retrieve logs at any time using simple queries, utilizing various indexes and forwarders. These components handle log parsing and aggregation, enabling us to easily identify all the security rules detected using Splunk. For instance, if we provide a hostname or IP source, we can obtain a list of the security details detected in that specific instance.

Splunk Enterprise Security has helped our organization reduce the threats and breaches from security attacks across various threat factors.

Our clients quickly realize the benefits of Splunk Enterprise Security, which is why they have continued to use it for so many years.

Splunk Enterprise Security has helped us reduce our alert volume. The total reduction in volume depends on the new use cases or devices that are onboarded. Initially, there may be a high alert volume, but we will analyze and work based on those alerts. Through this process, we cannot definitively state the exact percentage reduction, but it does significantly reduce the number of false positives in the environment, thanks to fine-tuning the use cases.

Splunk Enterprise Security has helped accelerate our security investigations. Splunk also offers the Phantom SOAR, although I am not currently utilizing it. However, I am familiar with the Splunk platform, which can automate the process and promptly detect and block various types of actions. We can also easily analyze the Splunk programming language.

Splunk can save our analysts ten minutes of additional time compared to our previous solution when resolving alerts, provided that we have the necessary query knowledge. 

What is most valuable?

Recently, Splunk upgraded to version 9.0.02, which includes excellent data dashboards and visualization effects. This upgrade makes it easier for me to implement all the dashboards. I have created a dashboard that showcases all the VPN monthly data in one place, which is a beneficial feature of the new visualization effects.

What needs improvement?

There are deployment servers and other servers, and sometimes Splunk may encounter issues if there are non-reporting devices. We will receive alerts only for the administrators and deployment servers, but not for all servers.

When upgrading Splunk, we encounter certain issues. For instance, it does not accept older versions of the other tools we use. This is the main problem. For example, if we are using a ticketing tool or any other XDR or EDR solutions, we need to upgrade them when we upgrade Splunk. During this process, we will encounter some difficulties, resulting in delays. Ideally, the upgrade process should first accept the current versions and then prompt for an upgrade, allowing us sufficient time to upgrade the other solutions. This helps ensure business continuity, although it may introduce some delays in upgrading all these processes.

For how long have I used the solution?

I have been using Splunk Enterprise Security for five years.

What do I think about the stability of the solution?

Splunk Enterprise Security is stable.

What do I think about the scalability of the solution?

We are satisfied with the scalability of Splunk Enterprise Security. It can increase its capacity and functionality based on our demands.

How are customer service and support?

Splunk technical support is good.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

I used ArcSight for Level 1 monitoring in my previous company, and my current company was using Splunk Enterprise Security when I joined.

What was our ROI?

We have witnessed a 60 percent return on investment due to the security that the solution offers to our organization.

What's my experience with pricing, setup cost, and licensing?

Unlike other security tools, Splunk provides a fixed amount of gigabytes per day, and we are required to pay for any additional usage beyond that limit, in addition to our monthly cost. I believe this pricing structure is reasonable for medium and large organizations.

What other advice do I have?

I rate Splunk Enterprise Security nine out of ten.

An organization that wants a CM solution but prefers to go with the cheapest option may work for a small organization, but not for medium and large ones. Splunk Enterprise Security is worth the cost for larger organizations.

Splunk Enterprise Security is deployed in a single location where it collects logs from various assets, infrastructure, and security tools. It serves as a monitoring tool, allowing us to view all the logs in a unified platform, including security tools, network scanners, portability management tools, and other infrastructure components such as Windows servers, Mission servers, and devices. Integration of these components occurs through different platforms like SCM or other platforms, enabling us to monitor everything in a single user interface using Splunk.

Maintenance is necessary for updates and patches. Additionally, we must be prompt with deployments as we need to monitor the health checks of the devices reporting to Splunk. It's crucial to remain active in this process to avoid any potential impact, so we should be mindful of that. Two admins are usually enough for maintenance, and if we encounter any issues, we can contact Splunk client support.

Resilience is important to capture all threat activities and threat speeds, such as IOCs, but we primarily focus on the ESF application. We integrate various threat intelligence platforms, including Splunk, which provides threats from different sources.

I recommend Splunk Enterprise Security as long as it fits within the budget.

Splunk Enterprise Security's single pane of glass enables us to easily monitor everything from one centralized location. Additionally, with its simple query language, we can retrieve all the logs in one place and generate reports quickly. This is exactly what security personnel require: fast reports and comprehensive log monitoring. It allows us to efficiently check all the security tools simultaneously.

Provides end-to-end visibility, improved resilience, and saves time
Pros and Cons
  • "The most valuable feature of Splunk Enterprise Security is the threat intelligence integration because essentially having to go out and correlate all the data on our own becomes convoluted."
  • "For us, the area that Splunk Enterprise Security can improve is performance optimization."

What is our primary use case?

We use Splunk Enterprise Security to ensure the security of our endpoints, including corporate workstations, tracking proxy logs, and all of the other benefits that Splunk Enterprise Security brings, including observability and visibility into the environment.

We run Splunk Enterprise Security on a single search head, and it talks to about nine separate clusters. It's a hybrid environment of on-prem and AWS. Ideally, we will migrate that to a search head cluster for Enterprise Security for high availability. Then, in the upgrade process, we generally have about two hours of downtime when we upgrade Enterprise Security. Ideally, moving to the cluster environment will allow us to mitigate that entirely. So, we did some assessments earlier in the year. We've gotta do some finalized testing, but we're hoping that will eliminate almost the entire two hours of downtime for our customers when upgrading. Then, it's two hours from start to finish to get the search head back up, and that does not include backfill time or anything like that. It could be a good full workday. So getting that workday back is going to be very important for us, and that's where I think we're gonna end up evolving for the Enterprise Security environment.

How has it helped my organization?

One benefit we have seen using Splunk Enterprise Security is keeping it all integrated, so no jumping between tools during investigations is the biggest benefit from the analyst's perspective. When we're setting up an investigation, it allows them to use one tool versus having to compartmentalize all the tools together, link it together, document it, and ultimately end up in one spot. Using Enterprise Security as it allows for integrated tracking for the investigations.

It's very important that Splunk Enterprise Security provides end-to-end visibility into our environment because not seeing something is a potential risk to the business. Having that visibility also assures the business, all the way up to the C Suite level, that there is coverage. And if not, we at least have that identified as an uncovered portion.

As long as we can point the data into Splunk Enterprise Security, it is easy to identify security events across cloud, on-premise, and hybrid environments. Getting it into Splunk is typically the challenge because it needs to be in a usable format. So once I've got it properly shaped and tagged, the rest trickles down. Generally, there are a lot of good TAs for getting data into Splunk around the cloud providers. So we don't have to customize it as much. It's just about getting it implemented, going through the checklist, and doing our due diligence to make sure we have the coverage we need. We will see events as long as they're flowing into Splunk. Once it gets into the data models in Enterprise Security, it will show up.

As far as ingesting data, Splunk Enterprise Security specifically hasn't helped. We shape and normalize our data to meet Enterprise Security's needs. So, we did that as a preemptive during our initial assessment. What does it come in as? What do we want it to look like? How can Enterprise Security more optimally use it? Will it hit the data models? Will it show up? Things like that. So, a lot of that is already there before Enterprise Security, but then using the data is where Enterprise Security shines. It makes the data more usable across all data sources. We don't have to know what to look for in each data type. We could go to the data model and view it.

We've increased our alert volume a little bit, not in a bad way, but getting new detections. The risk-based alerting has decreased. So what is happening elsewhere in the environment correlates with that event, and those risks are bubbling up to the top, whereas somebody getting locked out isn't as important as an account takeover. It's hard to portray that image with one event, but a series of events on the timeline makes it a little easier.

Splunk Enterprise Security lets us know who owns what hardware, who should access it, and who shouldn't, more specifically, during an investigation or escalation path. So we know there's a problem. Who do we talk to next to start that process and up the chain? We have a lot of that in there as well, which helps.

Splunk Enterprise Security has generally helped reduce our meantime to resolve. How much is hard to say because it depends on the investigation's scope and scale. It does help the analysts get a clearer picture of what's happening everywhere in the environment. 

Enterprise Security will automatically correlate those events for us. When an analyst gets assigned to that investigation, it becomes looking at the picture and putting the puzzle together versus having to go through a threat hunt or find those indicators and then identify the account lockouts and takeovers. It's already in one pane of glass, and then that gets us to the meantime to resolution quicker. 

It has decreased our mean time to detection, especially for the high critical alerts. When we leverage that risk-based alerting, we can say, alright, multiple events have now happened to propagate this into a larger event instead of trying to correlate that as an individual or a team of analysts. Ad hoc is going to always be slower than automatic. Doing it in the back end means my analysts get there and get the job done quicker.

Splunk Enterprise Security has helped with our organization's resilience. We generally use observability metrics to determine the state of the hardware and the status of the environment at the time, so that has been a good point. It's definitely made us more resilient to figure out what happened post-incident and on what time scale and then go back and try to either remediate or mitigate that wherever possible. The historical context is just as valuable as their live real-time learning context.

What is most valuable?

The most valuable feature of Splunk Enterprise Security is the threat intelligence integration because essentially having to go out and correlate all the data on our own becomes convoluted. We don't have the resources, so having that included in the product makes it easier for us.

What needs improvement?

For us, the area that Splunk Enterprise Security can improve is performance optimization. Enterprise Security is so critical that right now, we're working on getting it to a clustered state to have high availability. The challenge there is hardware procurement and utilization. It's very resource-intensive. A type of performance optimization would generally be a huge improvement.

For how long have I used the solution?

I have been using Splunk Enterprise Security for six years.

What do I think about the stability of the solution?

Splunk Enterprise Security seems stable to me. I haven't seen many issues, so I'm looking to try and test the latest version.

What do I think about the scalability of the solution?

Scalability is a mixed bag. So, when we first started Enterprise Security, they told us not to cluster it. Now they're recommending we cluster it. We haven't gone down that road yet. I am looking forward to it. But if they say it can scale, they have customers that have done it. We gotta go through the growing pains of implementing it, rolling it out, and making sure it's ready to go. I think it's possible, but I have no formal experience yet. I am looking forward to it.

Which solution did I use previously and why did I switch?

We started in Splunk, used it historically, and saw the product's value. It becomes the other data that would not be allowed for business reasons. How can we leverage that to provide value for the business? I know a lot about searchability this year, such as trace logs and metrics. These are generally good, but some trace stacks can be a lot of ingestion against our license. If we could put that in somewhere, that would not be as cost-effective, ideally. The trade-off is performance. Splunk is very performant. It does its job well. It's just a little pricey for the non-business critical logs.

How was the initial setup?

The deployment is generally good. We must stand up the search heads, get them ready, tie them into the index clusters, and then deploy. Generally, we don't expose anything to the customers until it's production-ready. So deploying it was just getting it out there and built, doing some finalized testing to make sure it's ready to be used by the end customer. 

What about the implementation team?

We implemented Splunk Enterprise Security ourselves. Through Splunk, we've engaged some professional services to ensure that our plan of attack is moving in the right direction. Professional services have also provided a lot of guidance.

What was our ROI?

We have seen a return on investment with Splunk Enterprise Security. Getting that holistic view. Splunk gives us a better picture of what's going on in our environment. Without it, we would have to go hunt for it. It's like Google searching for logs. It's easy, and everybody uses Google. So it's time-tested in the market. It's just about how much data we can get in, how we're storing it, retention, pulling it back, and what goes with that associated.

What's my experience with pricing, setup cost, and licensing?

While Splunk offers generous developer licenses and obtaining annual licenses is straightforward, the cost is a major consideration. As open-source competitors become more sophisticated, Splunk will need to address this pricing issue in the future.

Which other solutions did I evaluate?

We have not used other SIEM tools in the past, but we are evaluating other tools. We don't want to migrate away from Splunk. We want to replicate it at a larger scale for non-security-based data, such as application and developer data. Anything they want to throw in and search is fine. But at Splunk's current cost, it is generally very expensive to do non-business-critical logs in that environment.

What other advice do I have?

I would rate Splunk Enterprise Security eight out of ten. Things that could be better would be further integrations into other security tools. I know a series of threat intelligence feeds can be integrated, and I'm sure they are slated. It's just a matter of getting the resources to integrate them.  Splunk Enterprise Security is a solid product. I run it in my home lab as well. It's generally one of the better Splunk apps.

Which deployment model are you using for this solution?
