Performance monitoring impacts operations with fast storage setup
Having eyes on performance for storage through the Analyzer is valuable for me. The Ops center from Hitachi lets us see all storage in one place, unlike Dell and EMC, where we work on one storage. The Analyzer and the Ops center provide a better solution. Before this, we used a CVP with slow performance. This solution works better than before. The visualization vector in the last version is something we have. It is easy to work with and add the storage type. There is no difficulty in adding it.
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.

Pros

"Having eyes on performance for storage through the Analyzer is valuable for me."
"It was easy to set up."
"The Ops center from Hitachi lets us see all storage in one place, unlike Dell and EMC, where we work on one storage."
"There are quite a lot of things that we find useful; Splunk agents are useful and good, and its UI is quite impressive."
"Splunk Enterprise Security's value lies in its ability to collect and analyze security logs, providing insightful dashboards."
"Splunk Enterprise Security has been the best SIEM solution tool I have worked with over the past ten to fifteen years."
"The time it takes my SecOps team to remediate security incidents is very reduced compared to before."
"What Splunk does, and really is why it is a choice platform, is that it speaks all of those languages, no matter what IT discipline you are in."
"Its compatibility with other SIEMS is very useful."
"Log search and alerting/reporting."
"Splunk Enterprise Security definitely improved our operations."
 

Cons

"The dashboard needs improvement."
"Very limited people are available with resource availability in this region, and they have limited knowledge."
"I do not have any notes for improvement."
"There are some premium add-ons like Splunk Enterprise Security or ITSI which makes it more expensive."
"There is room for improvement for Splunk Enterprise Security. I moved away from Security Onion before switching to Splunk because Splunk was promising with Splunk AI, but now I am questioning if I made the right decision given that everybody is moving towards the AI aspect, especially since Splunk told me I cannot use Splunk AI on my platform and Security Onion already has the Gen-Sec SOC."
"The initial setup is complex, but this is necessary. We needed to take into consideration how to direct log files from thousands of machines to Splunk, and how to ingest those files."
"You do need a lot of training and certification with this product."
"There are sometimes issues with availability where you have to wait a bit longer."
"The main issue that I have with it is that the field transformations sometimes overlap with those in Splunk Enterprise, and then you get permissions issues that lead to troubles."
"Being able to have a one-stop shop where you have the alert, but then you can generate the case right there from Splunk Enterprise Security instead of having to pivot to another tool such as Mission Control. You do not have to keep bouncing between them, so if you could do it all in one place, that would be great. The new release is supposed to start getting in that direction."
"The only improvement I am expecting is the cost of the licensing. Clients are going to other solutions just because of the cost."
 

Pricing and Cost Advice

Information not available
"The tool's pricing model is great. You can choose between workloads or volume."
"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."
"Splunk Enterprise Security is affordable."
"While Splunk is more expensive than other solutions, we would still choose it because of its capabilities."
"It is quite expensive."
"Splunk Enterprise Security is not a cheap product, but I think it is worth every dollar that you pay."
"It is possible to use a developer's license, which is up to 10GB per day of volume traffic, which is usually enough for most use cases."
"I am not personally involved with the pricing of the solution."
