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 initial setup isn't overly complex."
"I like the ease of setting up dashboards on Splunk. They're easy to create, manage, alter, and share. You can fine-tune them any way you see fit."
"Splunk would be my choice for the presentation layer because it comes with inbuilt reports and a dashboard that you can customize."
"The flexibility of the solution is quite good."
"The features I appreciate the most in Splunk Enterprise Security are the scheduled alerts and the search function."
"The solution's most valuable feature is risk-based alerting, focusing on building out user risks for individuals throughout the enterprise."
"Splunk ITSI (IT Service Intelligence) has very good capability of storing, analyzing, and searching compared to other tools."
"It provides logs in one place, so they are easy to find. It collects the logs from multiple places, then you have just one place where you see the whole flow from the front-end to the back-end."
"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

"I would like to see ability to master management. In terms of clustering, how it manages clustering needs improvement."
"Over time I will have more requirements and I can foresee the solution could improve the search algorithm to run and output the data faster."
"Technical support needs to be more responsive."
"The GUI can be improved to include some of the capabilities that other BI solutions have."
"Its search or filtering capability is nice, but it can be improved. It is currently a bit complicated, and it should be simplified. If we can write the search filter in a more simplified way, it would be better."
". Having a trial version or more training on Splunk would be helpful."
"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."
"More training on PetaData using artificial intelligence techniques to identify the events which are not normal and exceptions that would help the organization identify threats and malware on the go with results."
"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

"My customers have found the price of the solution to be high."
"Setup cost is cheap: It is free, it is user-friendly, and it is fast."
"As a team, we prefer the old pricing model with a perpetual license. We are still evaluating the whole subscription-based model."
"While some clients find the cost of Splunk Enterprise Security to be on the higher end, its pricing is comparable to other SIEM solutions."
"Splunk is priced higher than other solutions."
"Our customers often complain that the price of Splunk is too high."
"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."
"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."
"It’s a single license platform."
