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

"You can check up on security from the dashboards."
"The solution's most valuable feature is the aggregation of all the logs in one place, using enterprise securities built-in or ESCU use cases to find them."
"While it might be an initial upfront investment on data onboarding, it's going to be something that makes your life incredibly easy once you get beyond that point."
"I am enjoying our implementation of risk-based alerting. That has helped very much with cutting out a lot of the noise that we have. It has reduced our alert volume significantly. There is about an 80% reduction."
"The biggest advantage I can see in Splunk Enterprise Security is the big data analytics."
"When we use a centralized log monitoring system we can see things on the dashboard and it is easier for the IT manager or an IT engineer to take corrective action in the system."
"The most valuable feature of Splunk Enterprise Security is the comprehensive logging capabilities it provides."
"Splunk Enterprise Security helped us with faster detection of threats."
"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

"The tool should include more real-world use case examples built out either through videos or in the community."
"The main improvement needed in Splunk Enterprise Security is its system visibility after installation."
"While Splunk Enterprise Security offers valuable features, its cost is high and could be more competitive."
"Licensing costs can be a barrier for those with limited budgets."
"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 with better AI integration, improved alert tuning, faster search performance, enhanced automation, and better visualization to understand the data."
"The only downside is the pricing."
"If we want to filter alerts, currently it's a very manual process. We identify IP addresses and usernames and must manually filter them."
"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

"Splunk is not a cheap solution and the license is billed annually."
"It is economical than other solutions."
"Splunk Enterprise Security incurs a significant cost because of the amount of data we send, but we are fine with the value we're getting for that price."
"I have no opinion on pricing."
"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."
"Price-wise, if you compare QRadar to Splunk for SIEM functionality then they are in the same range but when you integrate SOAR with these solutions, Splunk takes the lead and is more competitive."
"The price is comparable."
"Splunk Enterprise Security's pricing is pretty competitive."
"It’s a single license platform."
