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 product's initial setup phase was not at all difficult."
"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."
"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."
"Since the solution has been under way we have seen a large decrease of threats and proactive reactions to incidents."
"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."
"The solution is really scalable for the high-end power, enterprise customer."
"Packet Solution: Allows analyst proactive hunting and alerting on daily sophisticated APTs."
"The most valuable features are the packet decoder, log decoder, and concentrator."
"Splunk Enterprise Security scales well with the growing needs of our company."
"Out-of-the-box, it seems very powerful."
"The client site login is pretty extensible and probably cost-effective."
"The speed of the search engine"
"I have found the installation can be of medium difficulty to very complex depending on the use case."
"The most valuable features in Splunk Enterprise Security are the cluster capabilities."
"Splunk is user-friendly. We can easily customize the monitoring script."
"The correlation searches are most valuable just because we are able to do things like RBA."
 

Cons

"Cross Platform Integration could be improved."
"The user interface is a little bit difficult for new users and it needs to be improved."
"The documentation is not as structured as I would like, personally, and I think that it can be improved and made much more user-friendly."
"Log aggregation is an issue with this solution because there are a huge number of alerts in a single instance."
"Lots of competing products have vulnerability protection built into their products, and this solution would be improved by including that support."
"It should have a monitoring feature. It would help us analyze the current state of attacks faster from a single platform."
"It is not so easy to customize this product."
"The system looks like it is a mix of a bunch of different systems, and nothing looked like it was quite together."
"The administration of the cluster and app deployment to indexers or searchheads can be done only using ssh access and command line, there is no GUI tools for that."
"For us, the area that Splunk Enterprise Security can improve is performance optimization."
"Splunk does not build apps. They only go back and validate the apps that somebody has already built. They should have remote consulting support. They have a wonderful solution. They have 24/7 security. Nobody needs to depend on any third party and will therefore just buy Splunk on the cloud."
"Splunk Enterprise Security should provide a better and richer integration."
"Its user interface for everything other than the charts can be improved. Some parts of it can be simplified a bit, such as when importing documents that have the network traffic. When you're going through the information about the network traffic, you have to have the expertise, but even if a program is supposed to be for IT support, it is good to make it user-friendly because it gets easier to train people. When something goes wrong, the more difficult a program is in terms of UI, the harder it is to fix the issue."
"I would like Splunk to add more integration. QRadar has many indications with more products than Splunk."
"An improved user interface along with multi-tenancy support would be beneficial."
"When you get into large amounts of data, Splunk can get pretty slow. This is the same on-premise or AWS, it doesn't matter. The way that they handle large data sets could be improved."
 

Pricing and Cost Advice

"The tool is very expensive, so I rate the pricing a ten out of ten. The solution has an annual subscription."
"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."
"The new pricing and licensing mechanisms are fair. I would advise always to get the full solution (i.e., not only Logs)."
"Compared to the competition, the is price is not that high."
"In comparison to other SIEM solutions such as Splunk, NetWitness is less costly."
"We have a perpetual license, so the total cost of ownership is not very expensive. It's a good investment."
"The product price was reasonable for my region and the market."
"We have yearly licensing costs. The license fee can be based on the volume of EPS. Some organizations may have, as a gentlemanly gesture, 10,000 EPS and get a 3,000 EPS license but actually use 5,000 EPS."
"The price of Splunk Enterprise Security is high."
"We had a yearly subscription."
"Splunk Enterprise Security is expensive. I would rate the cost an eight out of ten with ten being the most expensive."
"Be upfront about your needs and expectations. Splunk is great to work with."
"Expensive compared to other options."
"Our ROI is high."
"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 pricing modules could be improved."
