It is a stable solution, but they should make the user interface easier to understand
The solution's initial setup takes work. We have to organize multiple paths and many features. The deployment process takes less than a week. But it takes a month to complete if we want to make the solution smarter by integrating it with various devices. I rate the process as a six out of ten.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"NetWitness Platform offers flexibility for deployment and robust integration capabilities."
"The most valuable feature is the ability to write rules and triggers for network communication, and then being able to investigate based on that."
"Setting up NetWitness is straightforward. There are multiple connectors, including standard and specialized connectors. One purpose of the connectors is the enhanced capability integrate the custom applications. NetWitness comes with E6 appliances and application images that we use for the initial configurations and for the OS stack information. From there, you can consider the correlation rules, integrate the different log sources, and easily create correlation rules and backlog reports."
"In my opinion, the solution's most valuable feature is its capacity to monitor network traffic, logs from devices within the network, and network captures. This capability extends beyond logs to include full network capturing."
"NetWitness Platform is valuable for creating rules that the solution must detect."
"The most valuable feature is the correlation. It can report in real-time and monitor the management."
"Their technical support responds quickly and are knowledgable."
"The development of use cases on the SSA console is quite user friendly. This means that the security analyst or the researcher does not have to learn another language."
"Splunk can deliver more information by going deeper. By creating a dashboard, we can identify the root cause of the threat. Let's say I have a firewall from Check Point. Splunk will find the dashboard for Check Point, implement it in our environment, and connect it to the Check Point firewall logs, which are shown on the dashboard. If we request a custom dashboard, the engineer will take longer to complete the task."
"It's great for finding anonymous threats."
"It helps us uncover bottlenecks in the network."
"You can run reports against multiple devices at the same time. You are able to troubleshoot a single application on a thousand servers. You can do this with a single query, since it is very easy to do."
"Incident detection is the positive impact I have seen from Splunk Enterprise Security; it probably saved the company from financial losses because of the early detection of the incidents."
"We can automatically suspend or terminate suspicious sessions."
"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 solve issues that we previously could not since we now have the data."
 

Cons

"The log system is a bit complex and has room for improvement."
"We have encountered issues with unresolved crashes."
"The multi-tenant capabilities are lagging compared to IBM QRadar."
"More customizability is required, which is something that they need to improve on."
"The threat detection capability and centralizing and upgrading capability need to be improved. The threat alert capability needs to be improved as well because there is some lag time at present. They need to work on their database search too."
"They should implement algorithms to digest that data and produce additional, more advanced reporting, alerting and support of internal security teams."
"The implementation needs assistance."
"I'd like to see improvement in its ease of use. It's basically unusable. It's overly complex."
"The integration with all our tool sets felt like we were reinventing the wheel, which was a pain point for us."
"We haven't saved any money with Splunk Enterprise Security. Instead, we have spent excess of the budget on this with unexpected costs."
"Sometimes talking through email isn't the most effective method, as they go through troubleshooting steps we've already taken, which requires additional back-and-forth communication."
"The solution is expensive."
"The training was mostly sales-focused, like how to monitor your sales. It was hard to then come back from doing the training and try to switch it to a cybersecurity focus because all the training we did was sales oriented. The basic training didn't really touch on any kind of cybersecurity use cases or anything like that. That would have been great to see in the training."
"On-premises scaling of the solution is a bit more limited than it is on the cloud."
"While Splunk offers SOAR as a separate product, integrating it into the next version of Splunk Enterprise Security as a unified solution would be beneficial."
"Splunk could add more ways to manage archiving and storage. There isn't a web interface. You can do this on the SaaS version, but the on-premise platform doesn't have this option. It has other things but no option for remote NAS. I would like to have a personal web interface where I can specify how long logs should be stored. To have this readily available on the web, you need to adjust some settings on the backend. That is tricky."
 

Pricing and Cost Advice

"The product price was reasonable for my region and the market."
"It provides tools to assist in selecting the appropriate license and usage scenarios."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"Compared to the competition, the is price is not that high."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"The NetWitness Platform may be affordable only for enterprise-level customers, as it may not be within the budget of small and medium-sized businesses."
"Splunk differs from other SIEM solutions by using a gigabyte-based pricing model, rather than the agent-based licenses common with its competitors."
"My customers have found the price of the solution to be high."
"Splunk Enterprise Security is an expensive solution."
"I believe there is room for improvement in reducing costs, particularly in the financial aspect, as Splunk tends to be pricier compared to other options."
"Splunk's costing is a little more difficult. The pricing method is complicated, and the way that costing is calculated in Splunk is a little more difficult."
"Price-wise, if you compare QRadar to Splunk for SIEM functionality then they are in the same range but when you integrate SOAR with these solutions, Splunk takes the lead and is more competitive."
"The price of Splunk Enterprise Security is high."
"While Splunk is more expensive than other solutions, we would still choose it because of its capabilities."
