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

"AI-driven capabilities will give me real-time detection and will protect my autonomous AI interruption."
"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."
"SentinelOne Singularity AI SIEM's AI-powered analytics does affect our SOC's ability to reduce false positives; that is one of the biggest advantages because the manpower that I have is limited."
"After using SentinelOne Singularity AI SIEM, it has reduced our incident response time by forty to fifty percent compared to other tools."
"Overall, I would assess the overall security posture after implementing SentinelOne Singularity AI SIEM as significantly better."
"It provides a lot of analytics with the underlying AI engine, and it is a lot easier than other solutions."
"The correlation capabilities are the first value that our clients say they like with Splunk."
"Positive features include replication capabilities, software development kits, and the architecture."
"It's extremely scalable. It's a very robust solution and certainly has the capability of handling far bigger data requirements than a lot of the other tools. Generally what ends up happening with me is that my clients tend, for the most part, to be mid-tier organizations where the cost of that solutions would be accompanying requirements for people just becomes way too prohibitive. Especially considering the model that they use for costing, which is based on the volume of data. Of course, they're going to put everything including the Coke machine as the ability to collect data off of it, because of course the more they can put through the tool the more money they make."
"The breadth of the data sources that Splunk can ingest data from is broad and deep and it does an exemplary job at handling structured data."
"It has a drag-and-drop interface, so you don't need to know SQL or Java to construct a query on Splunk. The resolution time is about the same, but it took longer to discover the issue with ArcSight. Our previous solution took about an hour or more, but Splunk can do it within a few minutes or an hour at most."
"The visibility is amazing with easy dashboard creation."
"We can quickly search for almost anything across many log sources in seconds."
 

Cons

"It is quite good, but the only downside is that it is costly."
"Another area for improvement is that the product is somewhat expensive. Pricing could be improved as well."
"At the moment, I feel the pricing is a little bit on the higher side, but the tool is positioned in a place where risk is very high, and we do not want to take chances, so we are prepared to pay the premium."
"SentinelOne Singularity AI SIEM has some performance and reliability issues that need improvement."
"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."
"The user interface is the main area for improvement."
"The Web Application Firewall will send you too much information because it's more dedicated to security than a normal firewall."
"Visualizations can improve. There are some performance and stability issues with the visualization layer."
"The security can be improved."
"The prices are complicated as we operate in a small third-world country."
"Its user interface for everything other than the charts can be improved."
"The price has room for improvement."
"While Splunkbase (the app repository) has a lot of great content, some apps are terribly old and could stand to be updated or purged."
 

Pricing and Cost Advice

Information not available

"Splunk Enterprise Security is an expensive solution."
"It is quite expensive."
"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."
"Pricing is probably its weakest spot. As compared to some competitors, Splunk is really expensive."
"The pricing modules could be improved."
"The cost is on the high end, which makes it difficult for some organizations to use."
"While some clients find the cost of Splunk Enterprise Security to be on the higher end, its pricing is comparable to other SIEM solutions."
