Senior Manager at Bank of America
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

"Splunk Enterprise Security can retain logs for compliance purposes longer than the usual three months."
"The detailed log view is easy to read."
"We use Splunk Cloud as a SIEM solution and to monitor traffic and the network for detection purposes."
"The best part of Splunk Enterprise Security is its customizable settings."
"The most valuable features of Splunk Enterprise Security are the enterprise search bar and the dashboards."
"The features of Splunk Enterprise Security that I consider the best include the platform's ability to search big data, the ease of writing SPL queries and finding this data, and the quality of the dashboards that are drawn very well, allowing the creation of any dashboards you want, as far as your imagination goes."
"Splunk is one of the most powerful SIEM platforms due to its flexibility, scalability, and advanced search capabilities as it uses the SPL language."
"The metrics and trends that Splunk Enterprise Security generates using all the data points we send allow customers to understand better what their users are doing."
"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

"My company could benefit from doing more Splunk training with Splunk consultants teaching us how to use it."
"The solution has a high learning curve for users. It's a little complicated when you're trying to figure out all the features and what they do."
"When you get into large amounts of data, Splunk can get pretty slow."
"An improved user interface along with multi-tenancy support would be beneficial."
"We'd like to have the number of devices covered under the license to be increased."
"The product must improve insider threat detection."
"Regarding Splunk Enterprise Security's AI capabilities in terms of accuracy and reliability of output, I think by default, they were not that good."
"Delays in responses from the technical team can pose challenges for both vendors and clients, especially considering that Splunk applications and machine solutions are critical assets."
"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 licensing model might seem expensive but with all the gain in functionalities you will have compared to traditional SIEM solutions I think it’s worth the price."
"The pricing seems good relative to the other vendors that we have had here. However, they need to find ways to be more flexible with the licensing and be able to deal with situations where we start generating more logs. Maybe having some controls in the Splunk interface to turn it off, so we don't have to change anything in our application."
"Unlike other security tools, Splunk provides a fixed amount of gigabytes per day, and we are required to pay for any additional usage beyond that limit, in addition to our monthly cost."
"Its pricing model can be improved."
"Splunk can be an expensive solution. It all depends on how we configure the alerts and the events from the endpoints. You can save some money if you do that correctly. If not, it becomes an expensive solution."
"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."
"Splunk Enterprise Security is priced lower than competitors."
"Pricing is pretty fair."
"It’s a single license platform."
