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

"It's effectively helped to reduce organizational risk."
"It is a robust solution. It provides great visibility."
"It is easy to collect and retain logs with SentinelOne."
"We collect a lot of telemetry from Singularity Complete."
"The portal is the most valuable feature because it provides us with a single pane of glass view and is highly intuitive."
"I really like the storyline feature."
"I like Singularity's rollback features, threat-hunting, and Ranger Insights. The Ranger feature scans the network and provides visibility into all the unsecured assets."
"In incidents, SentinelOne's remediation is excellent; we can immediately see if the threat type is dynamic or static."
"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

"One area for improvement is automated deployment. I use it through a group policy. I put in the PC name, and when the user logs in, if the PC is in that group, it attempts an MSI install through Active Directory via GPO. That seems to play a little havoc and can conflict with manual installs, causing issues where it wants to delete and reinstall the client."
"They could add “right click>scan” where most users were trained to do so in handling flash drives."
"Email security should also integrate with it to get more visibility on it."
"I think they should consider enhancing complete visibility."
"I would like to see category-based web filtering."
"Singularity's reporting isn't that great. The dashboards could be more customizable. It could be better integrated with other tools. SIEM tools provide better feeds. Singularity is a separate product altogether. It does not give enough information to integrate with different solutions to correlate better."
"The ease of use can be better in Deep Visibility. It is not always the easiest. If I have not been in there in the Deep Visibility module for a long time, I do not always find it that easy to use. I tend to go and have to consult the help quite often if I have not been in there a long time."
"There should be more integration models with different security operations tools or soft tools."
"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

"I don't know about the licensing model. It seems easy, but it's not my area of expertise. I don't have information on how it compares to its competitors, but the pricing is per device."
"Overall, it was a good experience. It is pretty easy for us to increase the number."
"I rate Singularity Complete four out of 10 for affordability. SentinelOne costs more than traditional antivirus solutions, but we get more out of it. It hasn't saved us any money, but it's an EDR solution, so we get a lot of value from it."
"The pricing of SentinelOne is less than McAfee."
"The pricing model is simple."
"My understanding is that we did a pretty good deal on SentinelOne. A part of that is because we were their customers very early on, and we also use their products a lot. We are interested in the new products that come out. We go to their demos, and we go to their events. We do save a lot of money. It is not cheap, but it is worth it. We spend a lot of money on a lot of things, and most of them do not do as much as SentinelOne."
"The price for it is very competitive compared to other Next Gen EPP."
"The solution's pricing is not too bad for what it's offering, like the documentation that comes with it."
"It’s a single license platform."
