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.

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

"They provide excellent predefined user cases."
"What is nice about the solution is that it makes it easy to build the queries, search for the events and then do analysis."
"Splunk has reduced application downtime by helping identify the point of failure."
"The best features would have to be the ability to ingest any data and display it in a way that anyone can understand."
"The most valuable features in Splunk Enterprise Security are the cluster capabilities."
"Positive features include replication capabilities, software development kits, and the architecture."
"In my experience, Splunk Enterprise Security detects incidents approximately 20% much faster than other tools."
"We can easily configure things as required in relation to our use cases."
More Splunk Enterprise Security pros
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"Resource usage can probably be described as an area with shortcomings in the product where improvements are required."
"The product's price may be an area of concern where improvements are required."
"It requires a significant amount of relatively complex architecture once you push past the single server instance."
"VMware and security device integration looks a bit complex."
"This is not really a monitoring solution."
"Splunk Enterprise Security can improve in the UI UX interfaces, but for the rest, I am very comfortable with the reporting, dashboard, alerting, search, and reporting features."
"The CIM model is the method Splunk uses to normalize data and categorize its important parts, but it is quite complex."
"Splunk Enterprise Security can be improved by addressing the content management interface, which is very outdated, slow, and clunky; sometimes we think things are saved and they haven't."
More Splunk Enterprise Security cons
"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

"There is an annual license required to use this solution."
"Our customers often complain that the price of Splunk is too high."
"Splunk can be an expensive solution. It all depends on how we configure the alerts and the events from the endpoints. You can save some money if you do that correctly. If not, it becomes an expensive solution."
"Unlike other security tools, Splunk provides a fixed amount of gigabytes per day, and we are required to pay for any additional usage beyond that limit, in addition to our monthly cost."
"We had a yearly subscription."
"Splunk Enterprise Security's pricing is pretty competitive."
"I remember Splunk being relatively affordable. Kibana was more reasonable, but you get more with Splunk. If I was suggesting something, I would probably suggest Splunk because it is better to pay a little bit more and get a lot more."
"Splunk differs from other SIEM solutions by using a gigabyte-based pricing model, rather than the agent-based licenses common with its competitors."
More Splunk Enterprise Security pricing and cost advice
"It’s a single license platform."
