MOTASHIM Al Razi - PeerSpot reviewer
CISO at One Bank Limited
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.
Sathis-Kumar - PeerSpot reviewer
Senior Manager at Bank of America
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 its ingestion of logs and raising of alerts based on those logs."
"The solution is really scalable for the high-end power, enterprise customer."
"Technically speaking, this is a good product."
"It gives the capability for the incident response team to correlate logs to identify any kind of problem like malware and incidents in a general sense, both for logs and packets."
"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."
"Overall, it is easy to implement."
"NetWitness can be highly beneficial for incident detection and response."
"The flexibility of Splunk as well as the resources available for learning and support are the best in the business."
"The risk-based alerting is excellent."
"The scalability of the solution is amazing because it can collect a lot of data and you can have your own structure to monitor this data."
"Splunk stands out for its extensive application integrations."
"Splunk has a single purpose in life: ingest machine data and help analyze and visualize that data."
"They have approximately 50,000 predefined correlation rules, which is quite a lot, and I find that good."
"Splunk is stable, and this is why many customers want it."
"Internal tracking is helpful because we do not like to deal with multiple ticketing systems, and I am not a fan of ServiceNow. We are able to keep everything internal and utilize Enterprise Security."
 

Cons

"The initial setup is very complex and should be simplified."
"Log aggregation is an issue with this solution because there are a huge number of alerts in a single instance."
"I cannot say that the solution was stable because it tended to crash."
"Nowadays, their support is a little subpar compared to other solutions. I rate RSA support six out of 10."
"It is not so easy to customize this product."
"We have encountered issues with unresolved crashes."
"The implementation needs assistance."
"Security needs improvement. We would still like to know how the traffic is entering the organization."
"I find the process for customizing, developing, testing, deploying, and refining detections in Splunk Enterprise Security to be cumbersome."
"The documentation is in definite need of improvement."
"The solution could be more user friendly and it's difficult to know at this stage whether our requirements will be met by the solution."
"There is a definite learning curve to starting out."
"The biggest thing with Splunk is making sure that the documentation is maintained."
"Splunk Enterprise Security is complicated in terms of developing specific cybersecurity use cases."
"One main change I would suggest is related to the incident board: when an incident is resolved, it should not appear on the incident board. It's just a rare occurrence that we open up the incident."
"Their sales support and tech support are really bad. They take really long to respond."
 

Pricing and Cost Advice

"It’s cheaper to run virtual machines in a VMware environment."
"The licenses are good but the cost is very expensive."
"We are on an annual license for the use of the solution."
"This is a pricey solution; it's not cheap."
"There is a licensing fee and the customer can choose whether he wishes this to be subscription-based or perpetual."
"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"RSA NetWitness Logs and Packets do not have a subscription model, it's a one-time purchase. There is only a perpetual license."
"The product is expensive."
"Splunk has always been on the expensive side."
"I would highly recommend anyone evaluating this option to download the free trial which allows for the ingestion of 500MB of data per day in order to get a feel for what Splunk does at its core. It will get pricey once your ingestion rates start to sky rocket, but I would consider it expensive given the amount of information that it allows you to analyze and react on straight out-of-the-box."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed."
"We have an unlimited one, and we pay yearly, but I don't know how much it costs. Previously, I worked for a startup, and when they started building it up, it was complicated for them because they didn't have the budget for that many licenses. It was very costly for them. So, startups might find it a little bit problematic because of the licensing, but for bigger companies, there is no issue."
"It can be cost-prohibitive when you start to scale and have terabytes of data. Its cost model is based on how much data it processes a day. If they're able to create scaled-down niche or custom package offerings, it may help with the cost. Instead of the full-blown features, if they can narrow the scope where it can only be used for a specific purpose, it would kind of create that market for the product, and it may help with the costing. When you start using it as a central aggregator and you're pumping tons of logs at it, pretty soon, you'll start hitting your cap on what it can process a day. Once you've got that, you're kind of defeating the purpose because you're going to have to scale back."
"The price of Splunk Enterprise Security is high."
"Splunk differs from other SIEM solutions by using a gigabyte-based pricing model, rather than the agent-based licenses common with its competitors."
"Splunk Enterprise Security incurs a significant cost because of the amount of data we send, but we are fine with the value we're getting for that price."
