The analytics and reporting can be a bit overwhelming. I love the dashboards, but I find that I need to better understand PowerQuery—specifically when to turn it on and off and its limitations. It's similar to SharePoint in that regard. As a former SharePoint instructor, I know it like the back of my hand. The best thing about SharePoint is that it can do whatever you want; the worst part is also that it can do whatever you want. You really need to know what you want before diving in. Most people usually have a good idea of what they need. SharePoint offers a lot out of the box, but you can customize it further if you wish. However, customization often requires hiring someone, which can be risky since you never know if it will work as intended. On the other hand, PowerQuery can help bridge some of those gaps within Singularity. The challenge arises when you want to incorporate what you've done into dashboards and charts, as there are limitations. For instance, I want more clickable drill-down options that allow me to filter on specific sections of the data, but that's currently not possible. It’s not to say that improvements won’t come in the future; it's just that it feels a bit early at this stage. Additionally, I find some navigation features frustrating, like the back button in certain contexts. For example, if you open PowerQuery from a chart, it doesn't open in a new window or tab. Clicking the back button takes you all the way back to the previous state, causing you to lose whatever progress you made. However, I'm actively providing this feedback to my partner, Pro Circular, through whom we access SentinelOne. They take our input seriously, and I've been sharing my observations. They have their own views but are addressing the issues I raise. It's good to see that suggestions occasionally lead to updates and improvements.

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

"The most valuable feature is that it just unintrusively works in the background to carry out the protection."
"Device control and network control are valuable."
"It has saved us from a couple of ransomware attacks already."
"The web portal has a really good web UI, and all the things are well integrated."
"The Microsoft integrations are most valuable right now."
"Prevents ransomware getting through."
"The solution can search for hidden and dormant threats on encrypted traffic in your environment."
"The most valuable features of SentinelOne are the endpoint detection of threats, and it does not only rely on signatures for detection."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"All is good for now, but we cannot rest, and continuous development - in particular with regard to the areas of automation, machine learning, and artificial intelligence - is required to keep ahead of the cybercriminals."
"I would like to see the reports from SentinelOne more customizable, as there are very few options."
"We did use the Ranger functionality. However, there was some scanning going on and it caused a lot of noise, so we had to disable it."
"I would like to see something a little more sophisticated than simply being able to mark a false positive as safe or there's usually just one or two options in certain areas and they're a little rudimentary at this stage."
"Interoperability with other SentinelOne solutions and other third-party tools is an area where you can run into some issues. Because of the way the agent works, there are sometimes things that are blocked or prevented from happening that are not identified as a threat, and therefore, not alerted in the console. Sometimes, we do have to dig through the logs, run tests, and adjust the whitelisting or exclusions to make sure that other applications will run properly."
"The solution could improve its notifications and communications."
"We'd like SentinelOne to upgrade automatically. It doesn't automatically update the agent if some system has an older version of the SentinelOne. It has to be triggered from the console."
"If it had a little bit more granularity in the roles and responsibilities matrix, that would help. There are users that have different components, but I'd be much happier if I could cherry-pick what functions I want to give to which users. That would be a huge benefit."
"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

"The per-seat cost is low, but you have to commit to a certain number of licenses for a year."
"The pricing of SentinelOne is less than McAfee."
"While the cost of SentinelOne Singularity Complete might seem high at first glance, it's important to consider the value it offers."
"The pricing is reasonable."
"SentinelOne can cost approximately $70 per device."
"The pricing is reasonable. It may be a little high, but it's on par with everything out there."
"The product's pricing is at par with what you see among major competitors. It's higher than McAfee, yet cheaper than CrowdStrike."
"Overall, it was a good experience. It is pretty easy for us to increase the number."
"It’s a single license platform."
