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

"The level of robustness on offer is very good."

"It is easy to use, and easy to implement."

"The integration and plugin availability are nice, the AI module is also great."

"Being able to track impossible travel logins and things of that nature is valuable. We can track user logins from various IPs, various countries, and at various times to see if everything adds up."

"If properly built, I'm very impressed with the stability of Splunk ES."

"It allows us to digest the information, the data, the different data streams, so we can make decisions based upon information that we receive, and it is pretty robust."

"Splunk Enterprise Security stands out for its ability to integrate with existing security tools, provide informative dashboards, and offer IT Service Assurance functionality that goes beyond basic threat detection to include service performance monitoring."

"I would assess the stability and reliability of Splunk Enterprise Security as very reliable and very stable."

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

"The biggest thing with Splunk is making sure that the documentation is maintained."

"Most of my interaction is with the user community, which is how Splunk wants it. When I need help, that community is very hit or miss."

"Its user interface for everything other than the charts can be improved. Some parts of it can be simplified a bit, such as when importing documents that have the network traffic. When you're going through the information about the network traffic, you have to have the expertise, but even if a program is supposed to be for IT support, it is good to make it user-friendly because it gets easier to train people. When something goes wrong, the more difficult a program is in terms of UI, the harder it is to fix the issue."

"I find the process for customizing, developing, testing, deploying, and refining detections in Splunk Enterprise Security to be challenging at times."

"Features related to content management must be improved."

"There is another new term called benign positives. It is better to clearly identify each definition of those terms since it has not been popular in the industry, and everyone needs to be aware of those things."

"Splunk Enterprise Security can improve in terms of probably being able to talk to additional sources."

"The licensing price is high and has room for improvement."

More Splunk Enterprise Security cons

"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."

"Support is an issue because they have a limited number of resources."

Pricing and Cost Advice

"The Splunk Enterprise Security license is expensive."

"Splunk is not a cheap solution and the license is billed annually."

"It's a yearly subscription."

"Splunk Enterprise Security is an expensive solution."

"The licensing model can be expensive, but the value it provides is significant."

"It would be nice if the pricing were cheaper. However, we did purchase it."

"I am fine with the licensing, but in terms of the cost, it is expensive for the data that we have. We have an open discussion with our account rep about this."

More Splunk Enterprise Security pricing and cost advice

"It’s a single license platform."
