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.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"We can ingest and correlate data from virtually any type of system."
"The solution is stable and reliable."
"Splunk's advantage is its search capability. Its search is notably faster. With Splunk, I can search easily on keywords. That is great."
"Splunk Enterprise Security is able to process a huge amount of data without any issues."
"Alerts when a server is malfunctioning, monitors external attacks, and takes action to stop spreading viruses."
"Correlation search, in general, is valuable because it allows us to search multiple data sources easily."
"UBA, User Behavior Analytics, is a key feature."
"On the cloud, we are pushing through less than half a petabyte of data. So far, it has been fairly stable because it runs on all the underlying AWS infrastructures."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"Splunk can improve its third-party device application plugins."
"Splunk should align its security principles with those of other vendors like SentinelOne. Splunk has mature APIs that can communicate with various security applications and devices. Splunk can process more to produce an understandable dashboard."
"The glass table feature does not perform as expected."
"It takes time to train people."
"Could be more user friendly."
"The historical data extraction needs improvement. I would like the capability of taking data and having it trend longer."
"The threat detection library needs to increase the frequency at which the playbooks are updated."
"We are waiting for Dashboard Studio to mature a little bit more. There are some things that we are using with Classic Dashboards which have not yet made it to Dashboard Studio. We are waiting for that."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"While some clients find the cost of Splunk Enterprise Security to be on the higher end, its pricing is comparable to other SIEM solutions."
"Regarding the product's pricing, I think it has always been difficult to have a conversation with Splunk."
"My customers have found the price of the solution to be high."
"Splunk Enterprise Security's pricing is pretty competitive."
"Splunk Enterprise Security incurs a significant cost because of the amount of data we send, but we are fine with the value we're getting for that price."
"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."
"The price of Splunk Enterprise Security is high."
"It's a yearly subscription."
"It’s a single license platform."
