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 log aggregation is great."
"Ease of correlation, creating correlation searches are easy and you can combine multiple sources with little effort"
"Splunk has give us the capability to easily track problems and their status."
"It has the ability to correlate data, analyze and review it."
"Splunk Enterprise Security is fast and well-documented, and user interface and user interaction are well-designed compared to other SIEM solutions."
"We have had a reduction in the time it takes to resolve issues and correlate what has failed, which has significantly helped."
"I find it beneficial that Splunk Enterprise Security easily integrates with other tools. Due to its excellent API capabilities, it facilitates connections with various cybersecurity tools."
"Splunk Enterprise Security gives us a single pane of glass so that we can use just one tool instead of having to use different tools."
"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 Enterprise Security can be improved by bringing back some of the operational use cases."
"Due to the size limit, we could not see the full product."
"Queries are not always as easy or straightforward as they might be, so it can be difficult to figure out what you need to look for."
"Improving the infrastructure behind Splunk Enterprise Security is vital—enhanced cores, CPUs, and memory should be prioritized to support better processing power. When we execute heavy, resource-intensive queries over long periods, the performance dips."
"We were inundated with the amount of alerts and alarms that we could get out of it. It is also a resource hog and we didn't have the resources to support it on-prem so we're taking it offline now."
"The solution could improve by giving more email details."
"Being able to have a one-stop shop where you have the alert, but then you can generate the case right there from Splunk Enterprise Security instead of having to pivot to another tool such as Mission Control. You do not have to keep bouncing between them, so if you could do it all in one place, that would be great. The new release is supposed to start getting in that direction."
"There is improvement needed when importing from some types of data sources. Most of the time you have to do some customization for the data because not everything is working the way it should."
"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

"Splunk Enterprise Security is priced lower than competitors."
"The price can always be lower, but it is fair at the moment. The cost efficiencies depend on the licensing and how much data we are bringing in. We have a fairly large footprint, so it is cost-effective."
"Splunk is definitely not a cheap solution. It is an expensive product."
"Most people share the same thought that the ingestion rates can get pretty pricey. There is a lot of work we do to curate the data that we send to Splunk so that it is not too noisy or too expensive."
"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."
"We have an unlimited one, and we pay yearly, but I don't know how much it costs. Previously, I worked for a startup, and when they started building it up, it was complicated for them because they didn't have the budget for that many licenses. It was very costly for them. So, startups might find it a little bit problematic because of the licensing, but for bigger companies, there is no issue."
"Splunk differs from other SIEM solutions by using a gigabyte-based pricing model, rather than the agent-based licenses common with its competitors."
"The tool's pricing model is great. You can choose between workloads or volume."
"It’s a single license platform."
