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

"The most valuable features are how stable and easy to use Splunk is."
"The solution's most valuable feature is the incident review, which gives a good overview of our security incidents."
"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."
"The initial setup is pretty straightforward."
"The technical support is among the best in the market."
"It is the best tool if you have a complex environment or if data ingestion is too huge."
"What is nice about the solution is that it makes it easy to build the queries, search for the events and then do analysis."
"Its huge, versatile AppBase helped me to configure and bring data from different sources to a unified platform."
"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 incident response technique should be available out of the box. That isn't as available as we would expect."
"The implementation and the scanning of the logs can be difficult."
"We usually have to follow up with technical support on our open cases."
"The upgrading process could be smoother."
"It needs integration with a configuration management solution."
"We would like more integrations with other cloud products, not just AWS, e.g., Azure."
"There is improvement needed when importing from some types of data sources."
"The cluster environment should be improved. We have a cluster. In the Splunk cluster environment, in the case of heavy searches and heavy load, the Splunk cluster goes down, and we have to put it in the maintenance mode to get it back. We are not able to find the actual culprit for this issue. I know that cluster has RF and SF, but it has been down so many times. There should be something in Splunk to help users to find the reason and the solution for such issues."
"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

"I believe there is room for improvement in reducing costs, particularly in the financial aspect, as Splunk tends to be pricier compared to other options."
"ROI is estimated at saving my team roughly 10 to 12 man hours per week in troubleshooting for our company as well as what our profits had been from our services of installing, configuring, and supporting other clients with the product."
"Splunk's costing is a little more difficult. The pricing method is complicated, and the way that costing is calculated in Splunk is a little more difficult."
"The pricing of Splunk Enterprise Security is high."
"It's a yearly subscription."
"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 Enterprise Security's pricing is pretty competitive."
"The solution is costly."
"It’s a single license platform."
