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."
"The Ops center from Hitachi lets us see all storage in one place, unlike Dell and EMC, where we work on one storage."
"It was easy to set up."
"It provides a lot of analytics with the underlying AI engine, and it is a lot easier than other solutions. There are some products that do automated AI-based detection and drawing up charts, but for network monitoring and all of the monitoring aspects, it is quite a nice tool. It is very convenient for business users because they get more or less a lot of data readily available. If you're familiar with the Splunk query language, you can pretty much do whatever you want."
"Splunk Enterprise Security is a platform that justifies its status as a leader."
"The best features Splunk Enterprise Security offers include the ease at which changes can be made as an engineer or as a lead to deploy rules, and the whole process is faster, it is easier, and it just gets done a lot quicker, generating a lot less frustration."
"There are lots of free learning materials on their website."
"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."
"Splunk Enterprise Security has helped speed up our security investigations."
"Splunk Enterprise Security has vastly improved the amount of time that it takes to respond to an incident, which has been truly helpful."
"We can automatically suspend or terminate suspicious sessions."
 

Cons

"The dashboard needs improvement."
"I do not have any notes for improvement."
"Very limited people are available with resource availability in this region, and they have limited knowledge."
"One thing I would like to see improved in Splunk Enterprise Security is a better user manual."
"Most importantly, Splunk can be outrageously expensive. That is the problem with both Splunk and Sentinel. Their pricing literally explodes based on the amount of data you feed in."
"The optimization of filters, which is easily achievable in software like Tableau, is not as straightforward in Splunk XML."
"It needs documentation, and "how-to-do" information. It's complicated to build reports and views."
"The analytics of Splunk could be improved."
"It is a hugely complicated product."
"Splunk's high cost, despite its recognition in our region, prevents many organizations from adopting Splunk Enterprise Security, suggesting there's room for improvement in their pricing strategy."
"There are some premium add-ons like Splunk Enterprise Security or ITSI which makes it more expensive."
 

Pricing and Cost Advice

Information not available
"The pricing depends on the bandwidth of an organization and is good compared to some SIEM tools. IBM, for example, is quite costly. But Microsoft Sentinel is notably cheaper."
"Splunk Enterprise Security's pricing is pretty competitive."
"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."
"Splunk Enterprise Security is expensive."
"You will eat up whatever you purchase quickly. The level of insights that Splunk empowers is addictive."
"I've heard Splunk is often preferred over other options, but the cost can be prohibitive for smaller organizations."
"Splunk Enterprise Security is expensive. I would rate the cost an eight out of ten with ten being the most expensive."
"Splunk Enterprise Security is not at all cost-friendly to be deployed in very small enterprises like start-ups."
