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.

Automated security monitoring increases efficiency, but market visibility needs improvement

I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Three features stand out for me: the SDK for writing Python, the customizable and adaptable diagnostic dashboard, and the optimizer for collecting data."

"The dashboard and reporting are very good... It provides very good visibility in a hybrid cloud environment, and you can build custom utilization APIs using Splunk."

"The solution's most valuable features are the granularity and analysis of the logs."

"We solve issues that we previously could not since we now have the data."

"The most valuable feature is that it brings all of the components necessary to identify, analyze, and respond together."

"I would assess the stability and reliability of Splunk Enterprise Security as generally good, with very few downtime, crashes, and performance issues."

"Support is quick and competent."

"The solution's most valuable features are its ability to transact in the cloud and its ability to onboard data easily with minimum connectors."

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

"It would be nice if Splunk reduced the cost of training. Their training sessions are way too costly."

"We are planning to do certifications, and there are many features, such as risk-based score and score detection, where the current training doesn't provide visibility to the analyst. They should offer training based on the features we use."

"Splunk Enterprise Security can be improved with better triage capability and less dependency on running SPL searches, which would allow analysts who may not have much experience in writing SPL searches to still use the tool and run investigations."

"It does not give us permission to implement on-premise so we implement them on the cloud."

"It'd be really nice if Splunk Enterprise Security had a better and solid configuration guide."

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

"While Splunk Enterprise Security is powerful, it presents significant complexity for users, as it's not particularly user-friendly for beginners."

"Endpoint access is the only issue I can think to mention, even though the endpoint access we have with Cisco is fine."

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

"Splunk Enterprise Security is expensive but the solution is equipped with a lot of features."

"I've heard Splunk is often preferred over other options, but the cost can be prohibitive for smaller organizations."

"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 price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."

"The pricing depends on the bandwidth of an organization and is good compared to some SIEM tools. IBM, for example, is quite costly. But Microsoft Sentinel is notably cheaper."

"Splunk is priced higher than other solutions."

"Splunk Enterprise Security's pricing is based on data volume, which generally suits large enterprises."

"Personnel costs are saved by not having to involve the domain developers from multiple teams when tracing a problem that spans multiple platforms."
