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.

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 the flexible log for identifying security threats inside an application. Sentinel is very good at this."
"Sentinel has positively impacted my organization by improving monitoring significantly."
"Novell SIEM was my second technology of this kind."
"The tool is simple to use."
"We can do advanced hunting queries and modify SQL queries to get desired results based on the rules triggering over the console."
"The most valuable feature of this solution is that it provides a central locking system for many event sources."
"The correlation engine allows our clients to generate rules more efficiently."
"The solution's Kusto Query Language (KQL) execution time is pretty good."

Cons

"The dashboard and customer view should be improved."
"This product's connection to certain types of cloud systems could be improved."
"Documentation for security aspects could be improved. It is difficult to find clear information about encryption or risks that are addressed."
"Frankly speaking, we did not find this product to be valuable, at all."
"This product's connection to certain types of cloud systems could be improved. We can do Microsoft, Google, and Amazon, but there are a lot of other things happening in the cloud that we do not connect well enough to. This product could be improved with better connection to cloud-based solutions."
"The solution does not allow outsourced authorizations."
"I would prefer to extend dashboards part and their functions in Web GUI version, so the charts could be for configurable."
"It's probably not a product that I would recommend to anyone."

Pricing and Cost Advice

"Sentinel's slightly on the expensive side."
"Sentinel is a subscription-based solution."
"The solution’s pricing is aligned with its competitors."
