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

"The Ops center from Hitachi lets us see all storage in one place, unlike Dell and EMC, where we work on one storage."
"Having eyes on performance for storage through the Analyzer is valuable for me."
"It was easy to set up."
"The most valuable feature of Splunk Enterprise Security is the threat intelligence integration because essentially having to go out and correlate all the data on our own becomes convoluted."
"It's extremely scalable. It's a very robust solution and certainly has the capability of handling far bigger data requirements than a lot of the other tools. Generally what ends up happening with me is that my clients tend, for the most part, to be mid-tier organizations where the cost of that solutions would be accompanying requirements for people just becomes way too prohibitive. Especially considering the model that they use for costing, which is based on the volume of data. Of course, they're going to put everything including the Coke machine as the ability to collect data off of it, because of course the more they can put through the tool the more money they make."
"Generally speaking, their support is pretty good and their response time is pretty good."
"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 recommend the solution and plan to continue using it."
"It provides a risk score for each object, device, or user. We can then take action if they are at a higher risk."
"Overall, Splunk is among the top three SIEM tools due to its capabilities and agility in bridging business analytics with security needs."
"We use Splunk Cloud as a SIEM solution and to monitor traffic and the network for detection purposes."
 

Cons

"Very limited people are available with resource availability in this region, and they have limited knowledge."
"I do not have any notes for improvement."
"The dashboard needs improvement."
"Splunk isn't appropriate for smaller companies. It's too expensive."
"Regarding customer service and technical support, their support is the worst I have ever run into in any industry."
"Beyond support, the pricing tier of Splunk Enterprise Security could be better, as it is an expensive solution; however, the cost reflects the value delivered."
"Writing SPL queries is tough at first with Splunk Enterprise Security, and the system gets a bit slow when searching through a large amount of data."
"Splunk Enterprise Security could be improved in the dashboards that provide KPIs about environmental behavior."
"Splunk is a very costly solution and I think it's the most expensive in the market in terms of costing."
"Professional support is great, but too expensive."
"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."
 

Pricing and Cost Advice

Information not available
"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."
"While Splunk is more expensive than other solutions, we would still choose it because of its capabilities."
"In addition to the licensing fee, there is also a support and maintenance charge."
"It is a pretty high cost solution, but if your organization has the funds, it can bring many benefits."
"The solution is a little expensive."
"You will eat up whatever you purchase quickly. The level of insights that Splunk empowers is addictive."
"Pricing can be a limiting factor. You have to continuously tune what you are bringing in and make sure what you bring in is of value."
"It is expensive. I used to buy it early on, but then they combined it into a higher-up organization. They buy it for multiple systems now. Last time, I paid around 60K for it. There is just the licensing fee. That's all."
