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

"The ability to manipulate data in Splunk is unparalleled. Splunk’s powerful, flexible query language can morph difficult to understand log formats into usable data."
"It's basically one of the best SIEM products on the market."
"Splunk has significantly reduced the time in performing the task of aggregating logs, reviewing as well as time spent during investigations."
"Low barrier to start searching with the ability to normalize data on the fly."
"It allows for transparency into IT metrics for insightful business analytics."
"Splunk's strength lies in its single-page view."
"Splunk has helped improve our company's resilience level."
"The scalability of the solution is amazing because it can collect a lot of data and you can have your own structure to monitor this data."
"It can integrate with almost any cybersecurity tool available in the market."
 

Cons

"I feel the solution to be too slow."
"We would like more integrations with other cloud products, not just AWS, e.g., Azure."
"There can be a bit of complexity around some fields during the initial setup."
"Sometimes, there is latency in the logs."
"Spam has different plugins but by default, the logs are not organized, it shows that there are roll-ups that are out of the box. I saw many plugins that can help improve or extend Splunk's functionality but I haven't tried any of them."
"We'd like to see a more seamless cloud-based integration."
"Splunk can improve its third-party device application plugins."
"We've sometimes faced issues with upgrades. The incident review dashboard sometimes breaks after updates. When we add a space or something in the description or anywhere in the SQL, the drill-down value may be reset with a blank value. Before rolling out any software, they should test it thoroughly and ensure clients won't have issues with the upgraded version. It should be compatible with all or most of the apps. All major issues must be addressed before rolling out the upgrade."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"Splunk is costly but it’s worth it due to the high-end features."
"The price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."
"The pricing could be made more competitive."
"I think we recently switched to the SVC pricing compared to the ingest pricing."
"While some clients find the cost of Splunk Enterprise Security to be on the higher end, its pricing is comparable to other SIEM solutions."
"The price of Splunk is too high for our market."
"Splunk Enterprise Security is a worthwhile investment given the comprehensive range of features it offers."
"I assume that the pricing is reasonable, because if it was too costly, there are other alternatives."
"It’s a single license platform."
