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.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

"It was easy to set up."
"It was easy to set up."

"The most valuable features are how stable and easy to use Splunk is."
"The most valuable features are the logs, which allow us to identify what happened and who interacted with the web repository."
"The dashboard and reporting are very good... It provides very good visibility in a hybrid cloud environment, and you can build custom utilization APIs using Splunk."
"The community marketplace is useful; often, you do not need to rely on Splunk Enterprise Security support due to the wealth of online documentation available—Splunk docs are truly beneficial."
"We have found all the features useful. However, the dashboarding and logging have been very helpful. Additionally, the log analysis does a great job."
"The most valuable features of Splunk Enterprise Security are reporting capabilities. It is a good tool for checking systems and analyzing situations. I find it useful to check my systems and analyze situations."
 

Cons

"I do not have any notes for improvement."
"Very limited people are available with resource availability in this region, and they have limited knowledge."
"The dashboard needs improvement."
"It would be good if the solution had some kind of copilot to automate or help write correlation searches."
"The price has room for improvement."
"Splunk's implementation process for managing multiple indexes can be complex, especially when dealing with a large number of components."
"I find that the learning curve for Splunk is relatively lengthy."
"Sometimes the communication with support happens with multiple staff. They should reduce the time to resolution."
"The product is relatively expensive."
"More control with Splunk Cloud as it seems a bit limited. I used to manage an on-premise instance of Splunk Enterprise and really liked having more control over it."
"The user access control could be much more granular, so that the admins can control r/w/x access for specific features of the product like dashboards, etc."
 

Pricing and Cost Advice

Information not available
"My customers have found the price of the solution to be high."
"The pricing seems good relative to the other vendors that we have had here. However, they need to find ways to be more flexible with the licensing and be able to deal with situations where we start generating more logs. Maybe having some controls in the Splunk interface to turn it off, so we don't have to change anything in our application."
"Splunk Enterprise Security is expensive."
"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."
"Splunk should be able to integrate with other product using the free version."
"Splunk ES is quite expensive compared to some products on the market."
"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 work for multiple clients. I am working for more than five clients, but most of the clients are switching from Splunk to Sentinel because of the cost. Even though Sentinel is very limited, clients are moving to Sentinel."
