Easy to manage, zero-trust option and supports both Linux and macOS
SentinelOne supports both Linux and macOS. All SentinelOne features were equally supported across Windows, Linux, and Mac, whereas CrowdStrike was more heavy on the Windows side. They did not support all features on Linux. The Singularity console provides a unified view. But we already had similar dashboards available to the ones we had engineered ourselves. So it's not a deal-breaker. For us, it was about supporting multiple operating systems. That was more important. So, these dashboards we have are third-party tools integrated with SentinelOne.

Correlates incidents, allows for quicker identification and helps prioritize investigations
The only challenge is, and that’s where we come into play, it’s a pretty high-tech platform. So, it’s difficult for small and medium-sized organizations to manage it on their own. It’s a very complex system. It requires a lot of expertise. All my guys who work on it have gone through certification from Stellar itself. There are three different certifications that you need to complete. Only then are you certified by Stellar to work on it. It’s a very complex platform. Not everyone can use it. A simple IT engineer or system admin won’t be able to handle it because it’s quite complex. You need to have an understanding of the industry, the subject, and the tool. So, just purchasing this tool or license and then using it on your own would be very difficult to configure and manage on a day-to-day basis. The pricing model is not suitable for small and medium companies, particularly small companies. The minimum pricing model they have is suitable for companies with more than one thousand users. So, if someone has 50 to 100 users, like typical small companies, it’s difficult for them because the cost involved is high. Stellar would charge you for those thousand users, but you do not need all those users. So what are they going to do? I guess Stellar does not want to target small companies directly and maybe relies on resellers and MSPs like us to sell it. So, that is something I would recommend changing. Otherwise, it’s a great tool, but because of the pricing model, small companies are unable to leverage the advantage of this beautiful tool. So, the pricing model should be suitable for small and medium businesses. The product currently has vulnerability monitoring and everything. But if they could also do something about vulnerability management and maybe patch management, that would be nice.

Quotes from Members

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

Pros

"The most useful feature of all is deep visibility."
"The process visualization, automated response, and snapshotting are valuable. The integration and automation possibilities are also valuable."
"The XDR capability is quite good."
"I find the product very easy to maintain and troubleshoot. Their engineers are very helpful if you need additional assistance. It's one of the best products I've used. It's easy to use from my standpoint, both for troubleshooting and with the support we get from their team if necessary."
"The security aspect is the most valuable feature for me."
"It is easy to manage and install. It has a very nice graphical interface that is very intuitive when end users are using it. You don't have to follow or read a book about 600 pages to have knowledge on how to use it. When SentinelOne is up and running, you can easily find your way."
"SentinelOne is very simple to install and very simple to manage. It's very aggressive, so it does protection well, and it seems to be stopping attacks that other solutions cannot."
"The deep visibility is a valuable feature. I can use it during threats or alert signals that we get. I can also use it when we have alert signals from other security tools that we have."
"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

"The product must provide the ability to update applications from the SentinelOne Management Console."
"The speed of investigation of the MDR service team must be improved."
"The MDM functionality and maturity still need improvement."
"The false alerts can be annoying, especially during administrative tasks."
"SentinelOne Singularity Complete is the best EDR in the market, but it will evolve, though I have concerns about using US partners in Europe due to the geopolitical context. It is better to work with European companies."
"Some of the reports that are exported through SentinelOne can be complicated for people who are not IT professionals. For example, we have some people within our leadership who would like to know why we are spending so much money on their product, and one of the ways that we are able to do that is through reports. Some of those reports are pretty easy to understand, and some of them are very complicated. Because they are not IT or security professionals, they may not have the same grasp. I wish their reporting feature was a little better."
"I would like to have a remote desktop feature added so we can remotely access our endpoints."
"Deployment strategy for large organizations that do not use active directory (AD)."
"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

"It is very affordable and easy to license, and it allows us to onboard new analysts quickly, with a turnaround time of one day at most."
"The one I use is $6 a month per device. Some are $4 and there are some that are more than that."
"Their pricing was extremely competitive. That is why we stayed with them so long. We are renewing at the end of next month. We have already put in the approval. It is all set to go. We are renewing for another year or so year over year. It has been a very effective product, and it has been priced very competitively."
"After negotiations, the pricing was found to be fair."
"The licensing is convenient, straightforward, and very clear."
"Just buy the Capture Client and buy the installer itself in a license of 100,000, or whatever is needed. You don't need to invest in any management tools because they are already installed, and maintenance from the client will keep everything up and running."
"While the cost of SentinelOne Singularity Complete might seem high at first glance, it's important to consider the value it offers."
"Its cost is similar to Trend Micro, but the protection is much better."
"It’s a single license platform."
