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

"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."
"Overall, I would assess the overall security posture after implementing SentinelOne Singularity AI SIEM as significantly better."
"After using SentinelOne Singularity AI SIEM, it has reduced our incident response time by forty to fifty percent compared to other tools."
"As an analyst, I could tell SentinelOne Singularity AI SIEM is the best tool because whenever I go to work, I spin up the tool and I am ready to work since it is so easy and the UI is good."
"Splunk Enterprise Security quickly gives us a view of an endpoint or a user or identity. If I want to look for an identity or an asset, I just quickly go into Splunk Enterprise Security. I know where to go and get a quick analysis for a respective object."
"It has quite extensive support in terms of integration. If you want to do anything, there are tools for that."
"It is a very stable solution. I never really had a hiccup with the tool."
"The solution's most valuable feature is the criticality of alerts."
"I really like the user interface and how it works."
"In the past we used the different application to collect logs. We used SurfWatch and VMware to do so. But, we found that the Splunk has more capacity to do more in less time. They provide a aster speed to index all the events , and this is a huge asset."
"Splunk can deliver more information by going deeper. By creating a dashboard, we can identify the root cause of the threat. Let's say I have a firewall from Check Point. Splunk will find the dashboard for Check Point, implement it in our environment, and connect it to the Check Point firewall logs, which are shown on the dashboard. If we request a custom dashboard, the engineer will take longer to complete the task."
"The most valuable feature is the DSS, also known as SPL, because it allows users to script advanced queries with limited knowledge."
 

Cons

"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."
"It is quite good, but the only downside is that it is costly."
"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."
"In terms of stability and reliability, I would give SentinelOne Singularity AI SIEM a rating of six for reliability. As I mentioned, it has very low reliability as a tool to use."
"Its setup is a little bit complex for a distributed environment. Their support can also be better. If we miss the response for more than a week, they usually close the case. Sometimes, it can take us more than a week to reply."
"Splunk can be an expensive solution. Technical support could be improved as well."
"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."
"The ingestion happens quickly, so you can run up the data costs if you use the default settings. It isn't a problem for government agencies in the Saudi market, but many of the corporations in India are small or medium-sized enterprises that cannot afford that kind of ingestion system."
"Splunk ES could have more pre-built integrations and rules. The detection is fairly accurate, but it depends on the rules you create. Splunk's out-of-the-box configuration isn't that useful."
"If possible, we would like to have not only a log monitoring system but a network monitoring feature in this solution as well."
"I would like the ability to view logs for specific instances and not have to pull the logs for the entire Cloud environment in Splunk."
"We were inundated with the amount of alerts and alarms that we could get out of it. It is also a resource hog and we didn't have the resources to support it on-prem so we're taking it offline now."
 

Pricing and Cost Advice

Information not available
"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."
"The price of this solution is expensive. However, it has great features. If you want a great solution you need to pay a price matching the features."
"It is possible to use a developer's license, which is up to 10GB per day of volume traffic, which is usually enough for most use cases."
"We have an unlimited one, and we pay yearly, but I don't know how much it costs. Previously, I worked for a startup, and when they started building it up, it was complicated for them because they didn't have the budget for that many licenses. It was very costly for them. So, startups might find it a little bit problematic because of the licensing, but for bigger companies, there is no issue."
"The pricing model is based on the number of gigabytes that you ingest into the Splunk system. So it can be an expensive solution."
"I think that most of the log analytics solutions are expensive and I'm not sure if it's worth it."
"I think the price could be improved."
"While licensing can be a concern, there are ways to reduce the licensing costs including filtering some events."
