It integrates well, reduces alert volume, and we can customize the dashboards
Pros and Cons
  • "Splunk Enterprise Security allows us to create custom dashboards by changing fonts and modifying widgets."
  • "I've noticed that onboarding data from various multi-cloud sources and diverse products, such as security network devices, can be challenging."

What is our primary use case?

We use Splunk Enterprise Security for various security use cases, including writing correlation searches. This has significantly improved both our use cases and correlation searches. We can leverage existing resources, making modifications as needed, rather than starting from scratch each time. Splunk Enterprise Security provides diverse use cases across different environments, including AWS, Azure, and multi-cloud setups, while also integrating with Microsoft Sentinel. Additionally, we can integrate Splunk's service orchestration product for further automation. Overall, this allows us to automate tasks that security analysts previously performed manually, such as reviewing incident dashboards. We can fine-tune alerts based on analyst feedback. Splunk's research team ensures that use cases are updated with the latest security content, enabling us to understand and implement necessary steps while customizing them to fit our company's needs. This is what makes Splunk Enterprise Security so popular; it streamlines processes compared to legacy security products that often rely on manual scripts. Clients, including government agencies and banks, are transitioning to Splunk Enterprise Security due to its reduced training requirements and comprehensive features. Everything is consolidated, simplifying training and certification. Additionally, integrating Splunk's service orchestration product further automates tasks and improves response times. The substantial investment in Splunk indicates its staying power; no other product on the market currently offers comparable capabilities. Cisco's acquisition of Splunk reinforces its potential for success, combining APM, data logging, and security portfolios. In one financial project involving 600,000 users, we were able to monitor all incoming traffic, identify security activities, and distinguish between legitimate and malicious traffic, including phishing attacks and potential identity-based threats. Splunk enables tracking individual identities, crucial for detecting attacks where perpetrators hide behind compromised identities, often leading to data breaches and other security incidents.

We implemented Splunk Enterprise Security to assist with AWS security, which includes GuardDuty, CloudTrail, CloudWatch, and Inspector. These AWS components generate compliance and security alerts, which we correlate and use to create dashboard reports and identify security events for various use cases. We then enable the out-of-the-box use cases and send notable events to the dashboard. The implementation is currently in its early stages.

How has it helped my organization?

Splunk Enterprise Security operates based on incoming data, making monitoring multiple cloud environments relatively simple due to data availability and integration capabilities. Data from cCloudRail, CloudWatch, Azure, and other diverse environments can be incorporated. While occasional patching might be necessary, most integrations are readily available, offering extensive coverage without customization. Specific customizations might still be required, but most functionalities are pre-built, leveraging code developed by Splunk. This efficient approach involves analyzing data from vendors like Palo Alto and applying add-ons to apply code and automate parsing.

Our visibility into various environments depends on how much data we incorporate; therefore, the more we scan, the better our visibility.

Splunk Enterprise Security's insider threat detection capabilities act as a secondary approval and vetting process, helping our organization ensure there are no unauthorized users.

The MITRE ATT&CK framework allows us to identify criticality levels, helping us respond to incidents. We might integrate incident response with a REST API, where a notable event triggers the creation of a ServiceNow ticket. Information flows from ServiceNow back to Splunk, which then feeds other systems, enabling bidirectional incident management. These processes are largely out-of-the-box, as Splunk integrates well with ServiceNow, except for any customizations. We understand the data integration requirements and leverage Splunk's extensive integration capabilities.

Splunk Enterprise Security does a good job of analyzing malicious activities and detecting breaches. The amount of information the research and threat detection teams receive from Splunk enables faster threat detection of up to 60 percent, eliminating the need to consult numerous sources. This efficiency is a key benefit of Splunk, as its significant investment in security allows for expedited processes.

I have seen the older legacy product where they have this manual process to identify issues, run scripts, try to identify the output, and then go through ten systems to collect data. This could take days. Now, with Splunk, we have everything correlated with multiple use cases, and we have a correlation search between multiple systems, along with application data. Splunk Enterprise Security can stitch all this information together and show it in a single pane of glass, which makes decision-making faster and allows us to focus on the relevant issues instead of wasting time on non-relevant ones. They have done this well.

Splunk Enterprise Security significantly reduced our alert volume. The initial challenge was dealing with a legacy IBM system that generated a massive amount of unfiltered noise, making it difficult to identify relevant events to send to the incident dashboard. This process was time-consuming and inefficient, and the value of the system wasn't apparent. To address this, we fine-tuned both the SOAR system and Splunk by applying filters and conditions to focus on relevant data. Ultimately, Splunk reduced the alert noise from 1,000 events in two hours down to ten, which were then grouped into a single notable event. Despite potentially having hundreds of background events, Splunk condensed this information into a single, actionable item, allowing us to focus on investigating the most relevant issues.

Splunk Enterprise Security accelerates our security investigations by reducing noise, allowing us to focus on relevant use cases. Everything is categorized as high, medium, or low priority, and people immediately start investigating high-priority issues connected to PagerDuty. Sometimes, this leads to on-call situations, sometimes immediate action. Service orchestration and playbook scenarios enable automated responses, like instantly blocking unauthorized access to a system. The possibilities for security use cases with playbooks and service orchestration are vast, and I'm excited to explore them further in the coming days.

The dashboards and reporting capabilities help to aid our security analysis.

We have integrated Splunk Enterprise Security with various services to streamline our security operations. This integration allows us to leverage diverse data sources for creating lookups, data models, knowledge objects, and regular expressions. By automating the development of use cases and regular expressions, we can apply them to data more efficiently, enabling faster implementation and analysis. This approach enhances our ability to detect and respond to security threats effectively.

Splunk Enterprise Security has enhanced our organization's security posture by providing comprehensive security compliance dashboard reports.

What is most valuable?

I appreciate how Splunk Enterprise Security connects users to the research team and threat documentation, providing access to current events impacting other clients, security vulnerabilities, and relevant use cases. The platform's daily updates offer valuable insights for enhancing our security posture.

Splunk Enterprise Security allows us to create custom dashboards by changing fonts and modifying widgets. Those familiar with XML coding can further personalize dashboards to align with frameworks such as MITRE. Alternatively, we have the option to use the pre-built dashboards.

What needs improvement?

I've noticed that onboarding data from various multi-cloud sources and diverse products, such as security network devices, can be challenging. Although Splunk has simplified data onboarding with features like data managers, they need to improve their out-of-the-box parsing capabilities. While they've made significant progress, covering about 70 percent of common products, there's still a 30 percent gap where manual configuration is required. This forces us to spend time understanding and writing custom parsing rules instead of focusing on data analysis. With Splunk's recent acquisition by Cisco, I'm hopeful they will prioritize enhancing this functionality and increasing their coverage to 90 percent or more.

I want to see Splunk Enterprise Security dashboards incorporate more features, such as out-of-the-box AI and user behaviour analytics, which are accessible within a single dashboard.

The technical support response time has room for improvement.

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?

Splunk Enterprise Security has stability issues, especially with large data volumes, increased data intake, complex dashboards, custom models, and processing that significantly impact performance. Many customers experience this; even with demos using small datasets, performance degrades with millions of data points. This necessitates capacity planning, dedicated teams, and enforced best practices. These practices include restricting complex searches, blocking problematic users, and providing training to prevent performance degradation. Constant vigilance and proactive measures are crucial to maintaining a stable Splunk Enterprise Security environment. I would rate the stability of Splunk Enterprise Security five out of ten.

What do I think about the scalability of the solution?

I would rate Splunk Enterprise Security's scalability six out of ten. We need to add more shared CPU memory and increase the capacity, and scaling requires a lot of planning and effort.

How are customer service and support?

Splunk's support quality has declined in the past five years. Response times are now slower, and resolving an issue can take weeks. Submitting a ticket and connecting with the appropriate support agent often requires numerous emails and calls.

How would you rate customer service and support?

Neutral

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

To improve security coverage and user experience, we replaced our outdated legacy solution with Splunk Enterprise Security.

How was the initial setup?

Our Splunk Enterprise Security cloud deployment utilizes a DevOps approach with a fully automated CI/CD pipeline. This automation has significantly improved our deployment speed, reducing the process from a week to a few minutes. Changes are made in the development environment and then automatically pushed to production after a click-through approval process. This streamlined workflow eliminates the previous manual process and associated delays, resulting in a faster and more efficient deployment cycle.

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

Splunk Enterprise Security's pricing is based on data volume, which generally suits large enterprises.

What other advice do I have?

I would rate Splunk Enterprise Security eight out of ten.

Splunk is widely used across larger organizations. While large organizations often have extensive teams dedicated to Splunk projects and upgrades, smaller organizations can also use Splunk, taking advantage of more affordable pricing options like the free tier for limited data. Cost isn't a significant concern for larger organizations, who prioritize Splunk's security features and are willing to invest in its capabilities.

Splunk Enterprise Security is deployed across all departments, processing millions of data points. Over 500 people manage this data: building dashboards and reports, working with Enterprise Security, discussing use cases, and creating custom data models. This represents a massive effort for any large organization where every department utilizes Splunk.

Government departments are transitioning to Splunk, with daily onboarding increasing the current user base of 5,000.

Because the deployment is cloud-based, the Splunk DevOps team handles maintenance.

Splunk offers a resilient SIEM solution with comprehensive capabilities for research and a wide range of use cases. It is constantly updated, ensuring it remains a valuable and comprehensive SIEM package.

I recommend Splunk Enterprise Security. It is an excellent tool widely used by many organizations, making it a valuable choice for security information and event management.

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

While I have experience with Azure Sentinel and other SIEM tools, Splunk stands out for me. It provides a full SIEM experience with informative dashboards, clear language for easy analysis, comprehensive visibility across my systems, and a robust CIM for data organization.

How was the initial setup?

The initial deployment was technical but not overly complex. We faced difficulties with the log process going down and not getting the results in the client console. The overall deployment took around three hours to complete.

Three people were involved in the deployment. 

What about the implementation team?

The implementation was completed in-house.

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

Splunk differs from other SIEM solutions by using a gigabyte-based pricing model, rather than the agent-based licenses common with its competitors.

While Splunk Enterprise Security carries a higher cost and requires budgeting, cheaper SIEM, and open-source alternatives often have limitations. This makes the decision a matter of weighing the cost against the features most important to each organization's security needs.

What other advice do I have?

I would rate Splunk Enterprise Security nine out of ten.

On paper, Splunk Enterprise Security is the top solution for detecting security threats in any organization, but Splunk Enterprise Security is expensive and most organizations don't have a proper budget to implement a SIEM solution. So they look for a more reasonable cost-effective solution. This is a hurdle for implementing Splunk Enterprise Security. It was originally designed for data science and modified for security. It is a top tool for SIEM and data analytics.

Splunk Enterprise Security stands out for its threat detection capabilities, but its cost can be a barrier for many organizations. Originally designed for data science, it excels in both security and analytics, but its price tag often pushes businesses towards more budget-friendly SIEM solutions.

Splunk Enterprise Security offers good resilience for our customers.

For organizations that don't have the budget for Splunk Enterprise Security, I would recommend Azure Sentinel.

Which deployment model are you using for this solution?

Monitors multiple cloud environments and integrates well with other tools
Pros and Cons
  • "It follows MITRE ATT&CK and Cyber Kill Chain frameworks. There are certain notable events for which we can configure our security posture."
  • "The support and the pricing can be better"

What is our primary use case?

There are lots of use cases such as finding threats, attack factors, and logs. It helps with rogue DNS or brute force attack detection. We have logs related to why a particular account was created. There is alerting. We can get some false positives, but by fine-tuning some of the things, we can reduce false positives.

Splunk is a security monitoring tool. It helps with incident handling, data logging, and observability of metrics. Splunk can handle all these things. Splunk Enterprise security is a premium app of Splunk through which we can have all the threat intelligence and incident reviews. It helps in finding all the attacks and Advanced Persistent Threats (APTs).

We also have dashboards. We can collect logs from different sources and applications. We can also troubleshoot issues. If we are having any issues with an application, we can go to that particular index to see what is the cause. If any application is failing or giving an error, we can troubleshoot the issue. We do not have to log into the server to find the error.

How has it helped my organization?

We monitor multiple cloud environments. We have GCP, Azure, and AWS. It is easy to monitor multiple cloud environments using the Splunk Enterprise Security dashboards. Splunk releases inbuilt apps, so by using those apps and add-ons, we can integrate it with our cloud environments. For example, for Azure, they have a Microsoft Cloud Services add-on. We need to register the app in Azure, and after registering the app, we have to use the tenant ID and set it up. There are a lot of inputs, and we can use all those inputs to onboard different logs from Azure. There is also the capability for HTTP event collection.

We have a hybrid environment, and that works best for us. For a lot of things, we cannot just go fully cloud. Hybrid is the best option for us. We are happy with the visibility that Splunk Enterprise Security provides. It is also about how we configure things. If we do not do it in the right way, we will not get visibility. We have to know what kind of tools we are using and what kind of data we are pulling. We cannot pull everything. We have to know what to pull. If we pull only what is required, we would not have any problems.

Splunk Enterprise Security comes with MITRE ATT&CK and Cyber Kill Chain frameworks by default. There are 12 processes in the MITRE ATT&CK framework. We just have to onboard logs, create the data models, and assign those ATPs to monitor all the kill chains. We can monitor all attack vectors and persistent threats that we want to monitor.

Splunk Enterprise Security is good for analyzing malicious activities and detecting breaches. I would rate it a 9 out of 10 for that. It can also go to 10 for different clients based on different requirements.

Along with Splunk Enterprise Security, we also install another Splunk app that has all the threat intelligence. We then feed the data through a CSV file and create the use cases. We set up alerts for those. In the case of an event, an alert is generated and assigned to a particular SOC analyst. There can be some false positives, but with proper configuration and filtering, they can be reduced.

Splunk Enterprise Security has been very beneficial and valuable for us. Our application teams can use the indexes to troubleshoot the issues they are facing at their location.

What is most valuable?

Being able to ingest data from all the tools and all the apps being used in the environment is valuable. Being able to create alerts when, for example, the CPU usage reaches 95% is also valuable. We can set up alerts and proactively fix the issues. Splunk helps with all these things, and Splunk Enterprise Security has almost 2,000 use cases. It follows MITRE ATT&CK and Cyber Kill Chain frameworks. There are certain notable events for which we can configure our security posture. We can onboard all the logs through indexes and create dashboards to view what is going on in the environment.

What needs improvement?

Overall, it is pretty good. They are improving it every day. They recently released SC4S for onboarding syslog data. However, the support and the pricing can be better.

For how long have I used the solution?

It has been 8 years since I have been using Splunk. I am not a part of the core security team. I handle some parts of enterprise security, such as SIEM data models or the creation of some correlation searches and use cases. The majority of things, such as threat hunting or threat intelligence, are managed by our core security team.

What do I think about the stability of the solution?

We faced some issues, but we fixed them ourselves. We have around 10,000 knowledge objects running. All the knowledge objects should not be running all the time. They should be distributed over 24 hours so that the servers do not have any extra pressure at a particular time. We used to have an issue with our indexes going down. The CPU was being utilized 100%, and everything was getting stopped. We found the issue. We fixed that, and we are good now.

What do I think about the scalability of the solution?

It is pretty easy to scale. For Splunk Cloud, we log a ticket with Splunk support, and they start the process. It does not take much time. However, there is a cost involved in that. 

We have been ingesting 40 TB a day. We have three locations: The USA, the UK, and France.

How are customer service and support?

The SLA for Splunk Cloud support is not satisfactory for a customer. The turnaround time is a bit low. That should be fixed. I would rate their support a 9 out of 10.

How would you rate customer service and support?

Positive

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

I have not used any similar solution in my current organization.

In my previous organizations, I have used solutions such as Elk, IBM QRadar, and Microsoft Sentinel. Microsoft Sentinel is good. Splunk is better than QRadar. Splunk has a lot of capabilities. It makes it easier to do many things and do them correctly. It does not require as much effort as required in IBM QRadar and Microsoft Sentinel.

Splunk is a bit costly, but if we control our usage during our searches, its cost is okay. When not controlled, it becomes a bit costly.

To those evaluating Splunk and solutions, I would advise knowing the features they would be getting. Elk is open source, but there is an underlying cost of infrastructure. The cost almost becomes the same. You have to hire people who can work on Elk and then you have the underlying infrastructure cost.

How was the initial setup?

We were on-premises, but we recently moved to Splunk Cloud. We have been using Victoria for the last eight months. When going from on-premises to Splunk Cloud, Splunk recommends engaging professional services. 

What about the implementation team?

The migration was done by Splunk. For administration and maintenance, we have about eight people, but the number of users in the environment would be in the thousands.

The maintenance of Splunk Cloud is taken care of by Splunk. Customers do not manage the clusters. With the on-prem setup, we have to patch the servers, upgrade the servers, or restart them from time to time so that the rebalancing of the buckets happens properly. In Splunk Cloud, we do not have to do these things. We only take care of the data normalization part. All other things are managed by Splunk.

What was our ROI?

It does provide a return on investment.

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

It is a bit costly.

What other advice do I have?

Be clear about what you want and try to filter out as much as possible. Create role-based rules and assign them to users rather than assigning every role capability to all the users. Also, everyone should not have access to all indexes. Only certain people should have access. For example, if someone is from the AD team, he or she should have access to the particular index logging the AD logs. They should not have access to all of it. There should also be some kind of training before you give access to people so that they know which searches to use and which ones not to use. They should understand the impact of various things.

I would rate Splunk Enterprise Security a 9 out of 10 based on my experience and the work that I do with the core security team. They are pretty satisfied with it.

Helps with the functioning of an organization's security operation center and to detect anomalies in data
Pros and Cons
  • "The solution's most valuable feature is that it helps with our use cases to detect anomalies in our data and it is important to my company since we have a lot of data on different logs on the systems."
  • "Considering the contract thing and the whole legal area, it takes forever to get the contracts signed and to be able to agree to the terms and conditions for my company as well as for Splunk's team."

What is our primary use case?

The solution is used in my company to help the security operation center in work areas like detection, response, and investigation while maintaining cybersecurity standards.

How has it helped my organization?

My company has benefited from using Splunk Enterprise Security, which has helped us stay out of the headlines in newspapers. The tool helps detect threats early and respond to them effectively.

What is most valuable?

The solution's most valuable feature is that it helps with our use cases to detect anomalies in our data and it is important to my company since we have a lot of data on different logs on the systems. We need to be able to create insights that are indicative of malicious activities, which is one of the main purposes of having Splunk Enterprise Security in our company.

What needs improvement?

The product lacks cross-cutting capabilities. The features in Splunk Enterprise Security that were initially promised to our company are still not available. My company has been asking Splunk for some of these features to be provided in the product for years, and we have been promised that they will be introduced soon in the solution and be part of the product's next release.

I believe that the contract and the terms and conditions mentioned in it are areas where improvements are required.

For how long have I used the solution?

I have experience with Splunk Enterprise Security.

What do I think about the stability of the solution?

When it comes to the on-premises version, the stability of the product was quite reliable. When my company moved to the product's cloud version, we faced some major issues related to availability and dealing with events like data corruption.

What do I think about the scalability of the solution?

The product's scalability is okay. I do not think my company faced issues in the area of scalability.

How are customer service and support?

The product's support services were not great initially, but now they are in really good shape. Whenever my company connects with the product's support team, they listen to our questions and queries, so I feel that we are in a much better place now. I rate the technical support as eight out of ten.

How would you rate customer service and support?

Positive

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

My company has experience with ArcSight. We switched to Splunk Enterprise Security because we couldn't get good answers to our questions from ArcSight, and it was just not functional.

How was the initial setup?

The solution is deployed using the cloud services offered by Splunk. Recently, my company also deployed the tool on an on-premises model. In our company, we monitor both, cloud and on-premises, with our cloud instance.

In the beginning phase, I would describe the deployment experience as a costly and hard process. The migration process from on-premises to cloud was hard and took our company a year to complete. There were different kinds of roadblocks on our company's and Splunk's end. My company worked directly with the migration process associated with the product.

What was our ROI?

It is difficult to say whether I have seen an ROI since it is like trying to figure out how much an insurance policy works. I think that our company will receive a return on investment from the use of the solution since it helps the organization's cybersecurity team stay out of the newspapers. My company has always been able to deal with threats quickly with the product.

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

Regarding the product's pricing, I think it has always been difficult to have a conversation with Splunk. Considering the contract thing and the whole legal area, it takes forever to get the contracts signed and to be able to agree to the terms and conditions for my company as well as for Splunk's team. I like the direction Splunk stays in by thinking with the customers about how to reduce costs and only have that data searchable or available, which you need at a particular time. I like the path Splunk is going on, specifically its current trajectory. I appreciate the efforts put in by Splunk in the area partnership, which is what my company expects.

Which other solutions did I evaluate?

My company uses Microsoft Sentinel. A multi-SIEM environment provides my company with the best of both worlds. Sentinel has some good features, like Microsoft Graph Security, that the tool uses for the whole Microsoft ecosystem. Microsoft Sentinel is a good option for my organization.

In my company, Splunk acts as a product that complements Sentinel because the former lacks some features. I think Microsoft is strong in the area of service delivery. Microsoft's EDR tools, like Microsoft Defender, use Servers from Microsoft Graph Security, and my company benefits from such a type of integration, and we are able to send alerts to Splunk. In our company, if we start to ingest all the data we usually ingest in Splunk by moving to Sentinel, it will become too expensive, so we have to choose where to keep our data.

What other advice do I have?

My company has been able to reduce the mean time to resolve with Splunk Enterprise Security as it went down from a couple of days to hours.

My company has seen a significant reduction in alert volume. It was very noisy earlier, but lately, my company hardly sees any false positives.

It is super important that the solution provides end-to-end visibility of our company's environment because you can never know from where threats can materialize. The fact that users can correlate and ingest data makes sense and is crucial, considering the massive amounts of data.

Splunk Enterprise Security has helped improve our company's ability to ingest and normalize data, which is one of the tool's key benefits.

I would not say that Splunk Enterprise Security has helped solve problems in real-time scenarios, but it has helped solve problems on a near real-time basis. In my company, there is always some lag between the data that comes in and the ones being ingested and correlated. Splunk Enterprise Security aids in solving problems in a matter of minutes.

Splunk Enterprise Security provides relevant context to help guide our company's investigations, and it is very important and can be considered everything for our organization. In our company, we pull in data from assets and registries to give index-based alerts and be able to find owners quickly to notify them and respond to threats.

Splunk Enterprise Security's ability to help our company find any security events across environments is excellent. My company is really happy with Splunk Enterprise Security. The product helps our company find bad stuff when needed.

The truth is that it is very hard to deliver solutions that work at a certain scale. I think that one of the things I could say is that it is a solution that scales up at work. There are many organizations where solutions fail, and I can say that since I have been a part of the deployment of many other tools, it is hard to get many products to work. Splunk Enterprise Security works, and our company's analysts rely on it and trust it. I can only see improvements considering the strategies in terms of where the product's management team is going, and I believe that I will be able to rate the tool a nine out of ten pretty soon.

I rate the overall solution an eight out of ten.

Helps improve our incident response time, and provides great visibility, but the deployment is complex
Pros and Cons
  • "Splunk Enterprise Security's dashboards are a key asset."
  • "The presence of multiple layers creates a significant challenge for monitoring across cloud environments."

What is our primary use case?

We use Splunk Enterprise Security for threat detection on our network devices.

How has it helped my organization?

Splunk Enterprise Security excels at threat detection. We've developed multiple correlation searches leveraging security data. These searches identify threats and categorize them by urgency level, enabling our security analysts to prioritize and take swift action.

Splunk Enterprise Security has helped us improve our incident response time. We achieve this by ensuring our queries are completed in near real-time.

Access management focuses on storing and managing access controls, while identity management deals with user identities. For example, if we want to find IP addresses associated with CrowdStrike, we can use access management to look up their IP ranges. Then, we can check if any IPs match by adding them to a specific identity management lookup. Finally, by leveraging the combined identity and access management features of Splunk Enterprise Security, we can create correlations between these entities.

The security dashboard can be customized to display the information we need most quickly. It typically has seven to eight panels, each dedicated to reflecting specific data. While some initial data load time might be present, clicking on a specific panel will display its information as soon as possible. There can be delays in traditional dashboards when searching for specific data. To optimize this, we can create "base searches" within each panel. These predefined searches cover commonly used queries and fields. Alternatively, we can create a "summary index" that holds a longer span of pre-processed data. This summary index allows even large datasets to be displayed quickly when accessed through the dashboard.

Splunk enhances our team collaboration regarding security incidents. When a threat alert is received, we can click on it and choose "investigation in progress" from a dropdown menu. This selection redirects us to a dedicated investigation page for further details. For in-depth analysis, we can drill down into the logs to pinpoint the source of the issue. Additionally, the platform allows us to contact network devices to determine the root cause. Once the issue is resolved, we can close the investigation.

We monitor both AWS and GCP environments using Splunk Enterprise Security. 

Splunk provides threat intelligence capabilities that can be valuable. This, combined with the comprehensive set of dashboards available, allows us to effectively monitor for threats. We can also create custom apps within Splunk for threat detection. These apps can include custom dashboards or reports that display specific information. For example, we could create a dashboard that shows the number of users accessing unknown URLs or another that monitors a particular device for suspicious activity. An example of suspicious activity might be a device where the print command is being executed repeatedly but failing each time. This could indicate a malfunction or, potentially, a malicious attempt to exploit the system. Similarly, a sudden spike in activity, such as millions of clicks on a specific device within a short timeframe, could also be a sign of a threat. By monitoring these parameters within Splunk's threat detection features, we can identify and investigate potential security incidents.

Splunk provides valuable visibility across multiple environments. Whether we have an on-premises or cloud architecture, Splunk offers self-monitoring capabilities. Additionally, depending on our environment, we can leverage existing monitoring tools. For on-premises deployments, we can utilize the Martin Console alongside Splunk for comprehensive monitoring. Cloud environments often come with built-in monitoring handled by the cloud provider's support team. In such cases, Splunk can focus on applications and custom log data for deeper insights.

The threat topology provided by Splunk gives us a comprehensive overview of potential threats. By analyzing queries or notable events, we can identify and neutralize these threats.

Splunk does a good job of analyzing malicious activities.

Splunk has improved our organization's decision-making by centralizing all the information in our environment and allowing us to access multiple dashboards and reports in one place.

Splunk has helped us reduce our alert volume. By using Splunk, we can identify the root causes of failures, which in turn leads to a decrease in alerts.

Splunk accelerates our security investigations by enabling us to resolve issues and document them in Standard Operating Procedures or knowledge-base articles. This facilitates a swifter response to similar incidents in the future.

What is most valuable?

Splunk Enterprise Security's dashboards are a key asset. They offer comprehensive visibility across our entire environment, allowing us to diagnose and address security issues directly from the interface.

What needs improvement?

I would like Splunk to offer a quicker and easier way to run queries.

Splunk could improve its cost-efficiency for our organization by offering pre-built architectures tailored to specific environments. This would provide a clearer picture of required licenses and their implementation, ultimately reducing licensing costs.

The presence of multiple layers creates a significant challenge for monitoring across cloud environments.

For how long have I used the solution?

I am currently using Splunk Enterprise Security.

What do I think about the stability of the solution?

Splunk Enterprise Security is a very stable product, but there are occasional bugs that can appear.

What do I think about the scalability of the solution?

We can scale Splunk Enterprise Security up or down depending on our demands.

How are customer service and support?

The Splunk support team is helpful. For complex issues or on-demand requests, we raise cases with them. On-demand requests requiring impactful solutions are paid. However, for UK-based users, standard support is free and usually resolves issues efficiently. In some cases, the support team rushes to provide a solution without even looking at the issue.

How would you rate customer service and support?

Positive

How was the initial setup?

The initial deployment can be complex. It involves creating multi-site clusters for each location and configuring a cluster master for each. This is because the cluster master will replicate data across multiple sites, making the environment more complex.

Four people were required for the deployment.

What other advice do I have?

I would rate Splunk Enterprise Security 6 out of 10 because of the complexities that occur at times.

I highly recommend Splunk Enterprise Security for organizations seeking comprehensive security monitoring. Splunk offers a centralized platform to collect and analyze vast amounts of security data. This empowers us to gain full visibility across our entire IT environment, including applications, user activity, and potential security threats. Splunk provides insightful dashboards, reports, and real-time alerts to help proactively identify and address security issues.

While cost is a consideration, prioritizing features over functionalities for SIEM solutions can be risky. It's best to identify your business needs first and then choose an SIEM that offers the most relevant benefits to address those needs.

Splunk Enterprise Security is deployed across multiple locations and departments within our organization.

Splunk Enterprise Security required maintenance.

Detecting threats faster with end-to-end visibility and simple data import processes
Pros and Cons
  • "Splunk Enterprise Security helps me detect threats faster depending on the type of log I'm using. If I have a current company's log, I can easily detect it faster."
  • "The main improvement needed in Splunk Enterprise Security is its system visibility after installation."

What is our primary use case?

I use Splunk Enterprise Security to analyze logs and data. When it comes to hybrid or multi-cloud, Splunk Enterprise Security has helped me find events. I use event logging and event IDs, which has helped me.

What is most valuable?

Splunk Enterprise Security helps me detect threats faster depending on the type of log I'm using. If I have a current company's log, I can easily detect it faster. 

The ability of Splunk Enterprise Security to import data is simple. It is not hard; it is just an easy task that gives me what I want. 

The command line in Splunk Enterprise Security helps to search for specific queries, such as analyzing a security log to find login attempts and distinguish between failed and accepted passwords. 

End-to-end visibility in Splunk Enterprise Security is something that is appreciated. Splunk Enterprise Security is easy to use. 

The Threat Intelligence Management feature in Splunk Enterprise Security is applied and helps me to normalize the data. 

Splunk Enterprise Security is part of the SIEM tool, so it helps me tremendously to do my work.

What needs improvement?

The main improvement needed in Splunk Enterprise Security is its system visibility after installation. When you install Splunk, you cannot see it on the system as an application. If you are unfamiliar with Splunk and download and install it, you will not see it as an application on your system. You have to go back to your browsing history to get the link and start using it again. Additionally, Splunk Enterprise Security does not always provide an immediate response to alerts on threats.

For how long have I used the solution?

I have been using Splunk Enterprise Security for three years now.

What do I think about the stability of the solution?

Scalability in Splunk Enterprise Security is satisfactory.

How are customer service and support?

I have not needed any help from the support team at Splunk before, so I have not required any assistance from them.

How would you rate customer service and support?

Positive

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

Splunk Enterprise Security was the first solution I learned, and it remains the only one I am using now.

I use a whole lot of tools at the moment aside from Slunk. I use Wireshark, I use Kali, I use Splunk Enterprise Security, and I use Metasploit.

What other advice do I have?

Splunk Enterprise Security can make mistakes, so we do not solely rely on the out-of-the-box detections. It can also be part of a hybrid or multi-cloud environment. Everything depends on who teaches you Splunk Enterprise Security. Someone can teach you, and it becomes simple, or it can become complex. To me, it is not complex as I am experienced in using Splunk Enterprise Security.

I utilize Splunk Enterprise Security to analyze and conduct investigations as part of my job. There is minimal intrusion, so I receive few alerts regarding malicious threats. We do not have a partnership with them; we use it as a normal user through the internet.

Regarding sustainability, manufacturers must continually update their products, add new features, and optimize them. They need to optimize extensively because with threats and vulnerabilities, we always have to update to the latest features.

Overall, when it comes to performance and reliability, I rate Splunk Enterprise Security an eight out of ten.

Offers flexible data ingestion and searching capabilities
Pros and Cons
  • "What I appreciate the most about the product is the flexibility with data ingestion and searching, which is very powerful; you can do whatever you want with it."

    What is our primary use case?

    My use cases are SIEM basically, which means using Splunk Enterprise Security as our SIEM effectively. We are taking all of our data from on-prem and some of our cloud services and importing them into Splunk Enterprise Security, then creating and generating alerts and reports based on some of our security use cases.

    What is most valuable?

    What I appreciate the most about the product is the flexibility with data ingestion and searching, which is very powerful; you can do whatever you want with it. We were able to see its benefits pretty much right after we got it implemented.

    What needs improvement?

    The UI sometimes can be laggy and not responsive. Additionally, some places need to be refreshed from a UI visual standpoint; I think they're starting to get better at that. Splunk Enterprise Security has come along much better since when we started looking at it.

    We use the cloud version, the Splunk Enterprise Security Cloud version, so we don't have access to a lot of the back-end functionality. Not having used it on-prem and just going straight to the cloud means there are some nuanced differences in how things are managed. If you look up documentation it says, 'You need to update this file,' and I cannot access that file. The translation between on-prem and cloud for some of the configuration elements needs clarification.

    For how long have I used the solution?

    I have been using it for a year and a half.

    What do I think about the stability of the solution?

    Stability and performance are pretty good for the most part, with only the UI lagging sometimes. Depending on the screen, it can take a while to load.

    What do I think about the scalability of the solution?

    Regarding scalability, it's hard to really say as we haven't had to build out anymore since implementation. However, we've been able to input most everything into it, and we don't have to do any rescaling as it happens automatically, which is beneficial.

    How are customer service and support?

    I have contacted their technical support, and they are pretty good for the most part. There have been a few times when things were prolonged, but overall, the support has been good.

    How would you rate customer service and support?

    Neutral

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

    I have not used any alternative solution.

    How was the initial setup?

    The initial deployment was pretty easy for our company. It took us three months to fully deploy it, and we are maturing as we've been progressing. We have had many transitioning use cases, but getting the data in was pretty straightforward.

    Splunk Enterprise Security doesn't require much maintenance on our end, just patching and occasional app updates. Most of it is just configuration work and not application updates, which is beneficial.

    What about the implementation team?

    Our whole team manages it right now; it's not a one-person job.

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

    I am somewhat familiar with the pricing. Generally, it seems expensive, though I don't think it's the most expensive option. Sometimes it can be confusing to determine the best way to utilize everything based on our pricing tier.

    What other advice do I have?

    I would rate Splunk Enterprise Security an eight out of ten.

    Which deployment model are you using for this solution?

    Public Cloud

    If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

    Provides users with insights and the ability to send alerts to analysts
    Pros and Cons
    • "The benefits my company has seen from the use of Splunk Enterprise Security revolve around the speed of detection it offers."
    • "I think the only thing lacking is that there are some answers that I couldn't find about the tool without reaching out to support, and it had to be escalated to the engineering team."

    What is our primary use case?

    I mostly use the solution in my company for incident response, ticket management, and integration with other endpoint products.

    How has it helped my organization?

    The benefits my company has seen from the use of Splunk Enterprise Security revolve around the speed of detection it offers.

    What is most valuable?

    The most valuable feature of the solution is the correlation searches. The one-stop shop shows me all my insights, and alerts, and can send alerts to my analysts.

    I would say it is fairly important for my organization that Splunk Enterprise Security provides end-to-end visibility in our environment. At the same time, my company has other products that cover the observability piece. From a security perspective, we use data outside of our security data to piece together the whole picture. I think our company's perspective is that no matter how we get the whole picture, we will do it, even if it is from outside Splunk Enterprise Security. I think Splunk Enterprise Security plays a major role in this.

    In terms of Splunk Enterprise Security for helping our company find any security event across multi-cloud, on-premises, or hybrid environments, I would say that it is great once you get past the learning curve. The learning curve is higher than normal.

    I think Splunk Enterprise Security has helped improve our organization's ability to ingest and normalize data in a great manner. Splunk is a great product and provides these features, but not so much when it comes to identifying and solving problems in real-time because there are always data delays. There is always onboarding, mapping, creation of correlation search, and then enabling Splunk ESCU part. It works in a general sense and not on a real-time basis.

    In terms of whether Splunk Enterprise Security has helped reduce alert volume, I would say that it is the only active SIEM tool my company is currently utilizing. Reducing alert volumes involves tuning up certain areas of the engineering team. If I look at the product alone, I would say it can help reduce alert volume. If I consider the learning curve, I would say that you have to learn how to tune it the right way with the help of professional services or experts. You need to utilize your resources, which I think is the best way to do it.

    Splunk Enterprise Security provides our company with relevant context to help guide our investigations since the correlation searches with the enriched data do help gain insights on all of our investigations. At the current point, we are still trying to get past the tool's learning curve so that all of our analysts and everyone on the security team can utilize the tool the best way they can. The more they learn, the better it gets, so currently, we are doing our best.

    Splunk Enterprise Security helped reduce the meantime needed to resolve our issues because we have all our data in a centralized location and mapped to a data model. As long as we know what detection and data we are looking at, we can go to our data model and figure out where the issue lies.

    Splunk Enterprise Security's ability to help improve our organization's business resilience revolves more around observability. Our company recently migrated to Splunk Cloud, and I think we have more hands-on experience with the ingestion side than ever before. I think it is a lot easier for us since we moved to Splunk Cloud as we don't have to focus on maintaining the infrastructure so much, and we can focus more on the data. I think this is outside of Splunk Enterprise Security's scope and falls under Splunk Cloud's capacity.

    Speaking about Splunk's unified platform helping consolidate networking, security, and IT observability tools, I would say that my company is not there yet.

    What needs improvement?

    In the next release, I want Splunk to offer more openness to integrations with other products that may be more of a preference for my incident response teams.

    For how long have I used the solution?

    I have been using Splunk Enterprise Security for five years. I am an end-user.

    What do I think about the stability of the solution?

    In terms of stability, if configured correctly, it works great.

    What do I think about the scalability of the solution?

    With Splunk Cloud, I think using the tool's scalability feature is easy since one can just call the product's support team.

    How are customer service and support?

    The solution's technical support is great since they have been very responsive and very attentive while answering all my questions. If the support team can't answer my questions, they escalate it to their engineering team. 

    I have had nothing but good things to say about Splunk's technical team. There have been times when I had to rephrase my questions or when there were communication issues, but the time to respond, escalation, and the attempts in trying to find help and answers from the support team's end have always been great. 

    I think the only thing lacking is that there are some answers that I couldn't find about the tool without reaching out to support, and it had to be escalated to the engineering team. If this process is the only way I can find answers, I think it is a little bit limiting for an engineer who supports a real-time incident response team. I rate the technical support a nine and a half out of ten.

    How would you rate customer service and support?

    Positive

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

    I have personally not used any other product before Splunk Enterprise Security.

    How was the initial setup?

    The product's deployment phase was pretty easy to manage since our company has a migration team and support staff. We also had a really good project manager from Splunk to help us, who walked us through every step, and it was a great experience.

    The solution is deployed on Splunk Cloud, which runs on AWS.

    What about the implementation team?

    My company works with Splunk directly to help us with the implementation, and our experience with the product has been great.

    What was our ROI?

    I have not seen an ROI.

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

    The pricing model is great. You can choose between workloads or volume. I am not part of the conversation about pricing in my organization. I just know what I know about the tool from learning about Splunk.

    What other advice do I have?

    I rate the tool a ten out of ten.

    If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

    Amazon Web Services (AWS)
