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 Splunk queries are valuable."

"Splunk Enterprise Security has helped reduce our team's average meantime to resolve metric by about 50 percent because we are able to tune it to lower false positives and noise."

"You're in for a nice surprise, Splunk is fun, easy to use, and will give you the results you are looking for and more."

"The solution's most valuable feature is the criticality of alerts."

"We have had a reduction in the time it takes to resolve issues and correlate what has failed, which has significantly helped."

"We can automatically suspend or terminate suspicious sessions."

"Splunk Enterprise Security's biggest advantage is the ecosystem, as the large ecosystem can detect threats from a variety of devices, including firewalls and antivirus software, and because it has many built-in rules for detection already, I do not write many playbooks from scratch, which helps me get started on threat detection faster and enables me to predict, identify, and solve problems in real time so security incidents can be prevented."

"When using this solution for Security Information Management (SIM), I highly recommend importing data sources from the whole cycle for the service security chain."

More Splunk Enterprise Security pros

"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

"Customer support for Splunk Enterprise Security is good; sometimes it's not as fast as I would prefer, but it has been useful."

"Splunk can be an expensive solution. Technical support could be improved as well."

"It needs integration with a configuration management solution."

"I think Splunk Enterprise Security can be improved by providing more out-of-the-box contextual information for alert triage, investigation, and response."

"The incident response technique should be available out of the box. That isn't as available as we would expect."

"Splunk Enterprise Security can be improved with more integrations, and maintaining it can sometimes be problematic."

"Splunk Enterprise Security is a wonderful solution, however, the background configuration process could be better as the administration process is very complicated."

"They could offer pre-built search queries for everyday use cases like brute force attacks, DDoS attacks, and other security threats."

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

"From what I have seen so far, Splunk has multiple cost models. The one that we are using is pretty good when it comes to ingesting data into the environment. It has worked out pretty well."

"We have seen ROI and improvements as we have continued to use the product, but they are more reactive."

"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."

"It is expensive. I used to buy it early on, but then they combined it into a higher-up organization. They buy it for multiple systems now. Last time, I paid around 60K for it. There is just the licensing fee. That's all."

"The pricing of Splunk Enterprise Security is somewhat high, but comparing it with its benefits, it's acceptable. It depends on the type of business."

"I think we recently switched to the SVC pricing compared to the ingest pricing."

"Splunk should be able to integrate with other product using the free version."

"The price of Splunk Enterprise Security fluctuates based on the customer, but I believe it's quite costly, especially for our clientele."
