AI-driven monitoring has improved real-time threat detection but still needs better automation
I could see some workflows, but I am unable to do automated workflows. For example, some repetitive jobs or repetitive tasks I am doing, but I am trying to have less manual intervention on the front. I am raising some issues that should be resolvable. The SentinelOne team has told me that this can be resolved within a couple of months, but they are saying that it is in future for enhancement and it may take some time. So far, the numbers are great. Regarding disadvantages or areas for improvement, I could say that 35 percent of my manual effort can be detected since I implemented it very recently. I could be able to say my current data talks about only 35 percent, and it may improve further, as I am expecting. But I can only comment based on my alerts and events. The adoption rate will be less compared to other products, as this can be a time-taken process because all my data needs to be offloaded and the system needs to understand my existing alerts, logs, and other things. This will take some more time, probably another month. Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well.

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.

Quotes from Members

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

Pros

"Overall, I would assess the overall security posture after implementing SentinelOne Singularity AI SIEM as significantly better."
"When they face attacks such as ransomware and are dissatisfied with their existing solutions, they switch to SentinelOne Singularity AI SIEM, which is quite good in detecting unknown threats, cleaning the system, and handling ransomware."
"AI-driven capabilities will give me real-time detection and will protect my autonomous AI interruption."
"After using SentinelOne Singularity AI SIEM, it has reduced our incident response time by forty to fifty percent compared to other tools."
"The benefits my company has seen from the use of Splunk Enterprise Security revolve around the speed of detection it offers."
"It follows MITRE ATT&CK and Cyber Kill Chain frameworks. There are certain notable events for which we can configure our security posture."
"Generally speaking, their support is pretty good and their response time is pretty good."
"Great log management capabilities with flexible and comprehensive search capabilities, scalable and easy to use."
"Splunk Enterprise Security is able to process a huge amount of data without any issues."
"The solution's newly developed dashboard is pretty amazing."
"I like the Splunk dashboard and search engine."
"The search function for spam is like a google search. You just enter and it will quickly show you the results."
 

Cons

"It is quite good, but the only downside is that it is costly."
"In AI SIEM, the areas that have room for improvement are the parsers for third-party integrated data or for third-party data sources that are not native integrations, which could be made a bit easier."
"SentinelOne Singularity AI SIEM has some performance and reliability issues that need improvement."
"Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well."
"The upgrading process could be smoother."
"It's missing some features that other solutions have, such as the ability to upgrade the endpoint and perform endpoint universal forwarders from a deployment server instead of using a third-party solution, such as Puppet or Ansible."
"Scalability is always a question for this product."
"I'd love to see more integrations, which is one of the primary points of the key node with Splunk Enterprise Security."
"The on-premise integration with SOAR could be more simple; the cloud version integrates with SOAR very easily, but the on-premise SOAR and on-premise Splunk Enterprise Security are really not that easy, so I would appreciate if that could be improved."
"Their technical support sucks."
"Splunk could improve its default machine-learning models. Also, Splunk Enterprise's native threat intelligence isn't that good. I prefer a custom threat intelligence model."
"It is a hugely complicated product."
 

Pricing and Cost Advice

Information not available
"Splunk is expensive based on our current requirements, but it's obviously worth what we pay."
"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."
"In addition to the licensing fee, there is also a support and maintenance charge."
"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."
"Licensing is a yearly, one-time cost."
"The pricing could be made more competitive."
"I work on the technical side, so I don't know precise figures. However, I know that Splunk is a premium product, so it's somewhat costly. Still, you get a lot of unique features for the money."
"While Splunk offers generous developer licenses and obtaining annual licenses is straightforward, the cost is a major consideration."
