Daniel Giacomelli - PeerSpot reviewer
Strengthens cross-platform threat response while supporting audit compliance and log integration
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.

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 Deep Visibility feature is the most useful part of the EDR platform. It gives us good insights into what is actually happening on the endpoints, e.g., when we have malicious or suspicious activity. We came from a legacy type AV previously, so we didn't have that level of visibility or understanding. For simplifying threat-hunting, it is extremely useful, where traditional techniques in threat hunting are quite laborious. We can put in indicators of compromise and it will sweep the environment for them, then they would give us a breakdown of what assets have been seen and where they have been seen, which is more of a forensics overview."
"SentinelOne gives us visibility into various high-level vulnerabilities on every gateway on the network. It helps us prevent vulnerable devices from being compromised. We primarily use Singularity for its EDR functions. We're happy with that."
"The best thing is it has a secure shell command that you can use to get into any endpoint and do some jobs."
"The most valuable aspects of SentinelOne Singularity Complete are the ease of deployment with the Sentinel Agent and the enhanced visibility with Skylight, which provides correlation of logs and all endpoint data in a centralized location."
"It has helped to reduce our organizational risks."
"The solution is both stable and scalable."
"The security aspect is the most valuable feature for me."
"SentinelOne Singularity Complete has shown a return on investment with its ability to detect threats at approximately 99% efficiency."
"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

"SentinelOne's phishing feature could be improved."
"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."
"It is difficult to manage users in SentinelOne."
"The training for SentinelOne Singularity should be free. The solution has a lot of features but we do not know how to use them all. The moment someone purchases the solution they should contact them and provide them with a feature session on how to use the features."
"When comparing SentinelOne to CrowdStrike, I find that CrowdStrike has more comprehensive vulnerability assessment tools."
"The application management needs improvements, but I understand that they are working on it. We talked to them a few months ago, and it is something they are trying to get up to speed and fix. This way, we will be able to disable critical apps or vulnerable apps through SentinelOne. We will be able to patch applications or disable applications through the Application Management tab."
"An area for improvement in SentinelOne is the search feature. You can't go beyond twenty thousand events, which ruins the task because it isn't enough when you're doing your investigation."
"They can just continue adding more integrations with these big brands and software security products."
"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 price for it is very competitive compared to other Next Gen EPP."
"The cost of endpoint protection is fairly reasonable."
"We are on a subscription model by choice. Therefore, we are paying a premium for the flexibility. We would have huge cost savings if we committed to a three-year buy-in. So, it's more expensive than the other solutions that we were looking at, but we have the flexibility of a subscription model. I think the pricing is fair. For example, if we had a three-year tie-in SentinelOne versus Cylance or one of the others, there is not that much difference in pricing. There might be a few euro or dollars here and there, but it's negligible."
"SentinelOne Singularity Complete is expensive compared to Microsoft but not Sophos."
"SentinelOne is significantly less expensive than CrowdStrike. I recently did a price comparison between CrowdStrike and SentinelOne to determine where we are going for the next three years. CrowdStrike is 200% to 300% the cost."
"It is comparatively cheap in the market and provides a good price point."
"The product's pricing is at par with what you see among major competitors. It's higher than McAfee, yet cheaper than CrowdStrike."
"It is expensive. There is no doubt about it. If one of the functions does not work, it becomes very difficult for any CIO to justify the cost."
"It’s a single license platform."
