Simon Johnston - PeerSpot reviewer
Simple antivirus solution integrates well but could improve pricing and currency options
I don't really have experience working with these solutions. I promote them for our clients, but I don't work with them. I can't share my experience with these tools as I make assumptions about that. For both Adlumin and CrowdStrike, both confirm that they're scalable and enterprise-ready and all those kinds of things. We haven't had any specific problem with either of those. We just have a preference for which one we would prefer. If somebody says they want to use a different one from the one that we prefer, then we have to find reasons why they aren't. But scalability is not one of the reasons that one is better over the other. I don't really have advice for people that are looking into using Sentinel; just do your research across what is available. On a scale of one to ten, I rate Sentinel a seven.

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.
