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

"The most valuable features are the integration and ease of use."
"The most valuable features are the packet decoder, log decoder, and concentrator."
"The most valuable feature is that we can create our own connectors for any application, and NetWitness provides the training and tools to do it."
"Possibility to investigate incidents based on logs and raw packets, such as extracting files sent over the network"
"It gives the ability to investigate into network traffic in the Net and the organization what we couldn't do before."
"The most valuable feature of RSA NetWitness Logs and Packets are the alerts and correlations tools."
"Performance and reporting are very good."
"NetWitness can be highly beneficial for incident detection and response."
"On average, my security ops team takes fairly quickly to remediate security incidents with Splunk Enterprise Security, depending on the use case, minutes versus hours, compared to my previous solution, which was ArcSight."
"The visibility is amazing with easy dashboard creation."
"We used it to create a custom anomaly detection data model to monitor the activity of our back-end services on an hourly basis relative to the past three months of activity."
"Compared to IBM QRadar, Splunk Enterprise Security offers faster alert resolution."
"What I appreciate about Splunk Enterprise Security is creating the newest SPL for network traffic and using the risk-based alerting feature that helps my organization by allowing me to learn more information about Splunk every day because it is a big platform."
"An example of how these features benefited my organization is that the mean time to detect compromised accounts from the time that we're able to detect that account and then launch some automation to actually disable the account and work with the end user to fix the issue has gone from taking a couple of days to literally taking two to three minutes."
"Splunk Enterprise Security is probably one of the first products that actually could handle all the ingest and do all the correlation without crumbling under its own weight."
"I appreciate the integrations with the SOAR architectures and the expandability that can be used throughout the entire ecosystem of Splunk Enterprise Security."
 

Cons

"The initial setup is complex. There are other solutions that are easier to implement."
"The solution should have more integration capabilities with different platforms."
"The multi-tenant capabilities are lagging compared to IBM QRadar."
"The system looks like it is a mix of a bunch of different systems, and nothing looked like it was quite together."
"Sometimes, it gives me static when integrating Windows-based systems. It should produce a precise log of sorts as to where the problem is. For example, a few days ago because of the McAfee application firewall, I couldn't get access to the particular Windows machine. So, my team and I had to figure out by ourselves that there was a virus responsible for the obstacle. This solution should trigger a meaningful log or message indicating the reason the user or implementer can't get into the machine."
"The product's licensing models are complex to understand. This particular area needs improvement."
"The tool's integration capability isn't so great."
"More customizability is required, which is something that they need to improve on."
"The historical data extraction needs improvement. I would like the capability of taking data and having it trend longer."
"I have not seen ROI with Splunk Enterprise Security."
"Sometimes the communication with support happens with multiple staff. They should reduce the time to resolution."
"The biggest problem is data compression. Splunk is an outstanding product, but it is a resource hog. There should be better data compression for being able to maintain our data repositories. We end up having to buy lots of additional storage just to house our Splunk data. This is my only complaint about it."
"Splunk has a steeper learning curve, making it feel less user-friendly."
"A lot of people are averse to using new tools so if they make it even more user-friendly than it already is, I think that could go a long way."
"Writing queries is a bit complicated sometimes."
"Splunk ES could have more pre-built integrations and rules. The detection is fairly accurate, but it depends on the rules you create. Splunk's out-of-the-box configuration isn't that useful."
 

Pricing and Cost Advice

"We are on an annual license for the use of the solution."
"Our license is for one year."
"Many clients are not able to purchase the packet capability because there is a huge amount of data, and the cost depends on the number of EPS (Events per second), as well as the number of gigabytes of data per day."
"It is cheap."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"Compared to the competition, the is price is not that high."
"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."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"The pricing can be better. We are already considering Elastic because Splunk is too expensive. You have to pay based on per-day ingestion. There should be a more flexible model for the use cases where one day you have a huge amount, and on other days, it is quite less."
"The pricing is a little bit on the higher side, but looking at what Splunk provides us, it is reasonable."
"It would be nice if the pricing were cheaper. However, we did purchase it."
"The price of Splunk is reasonable."
"The price of Splunk Enterprise Security fluctuates based on the customer, but I believe it's quite costly, especially for our clientele."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed."
"The pricing of Splunk Enterprise Security is somewhat high, but comparing it with its benefits, it's acceptable. It depends on the type of business."
"The solution is a little expensive."
