A solid product for security, but the MSP program should be simpler
Their MSP program should be made much more simple. It's too convoluted in its process. They have two different kinds of people that sell their product. They have resellers and MSPs. A reseller would just be a company going and saying that I need licenses, and that in turn goes to eSentire, which then goes to the customer, and they do the transaction. We were on the MSP side. We were the ones who took a potential customer to eSentire, and we were the ones who closed the deals. We were the ones who went through everything, and in the end, it was just a notice saying that let's spin up a new tenant. That's the kind of difference we're talking about. From my standpoint, their MSP program, in general, needed to be worked on. It should be made much more simple. It's too convoluted in its process. I know it was in the process of being revamped, and as of the end of January, it was not finished. That was the last contact I had with eSentire, but I know that, at this point of the year, they were supposed to have rolled that new MSP program out to take care of all of the negative things. They were going through that process and making it much better. Once they get that implemented, they will be a good, solid vendor.

Centralized visibility has improved SOC investigations and supports faster, more accurate incident response
I think ReliaQuest GreyMatter could be improved further in a few areas. First, I want to see more flexibility in dashboard customization so analysts can configure views based on their roles and investigation requirements. Second, improving alert correlation accuracy and reducing overall false positive rates would help analysts focus on genuine possible threats rather than spending time validating repetitive low-priority alerts or false positives. Third, more detailed investigation timelines, better reporting capabilities, and simpler investigation integration configuration would make the platform more effective. I suggest continuously improving automation workflows to reduce repetitive manual tasks while allowing analysts to maintain control over critical response actions. Overall, I think these enhancements can make the platform more user-friendly and improve the efficiency of SOC operations. One additional improvement would be enhancing the investigation experience by providing more detailed context directly within the alert. For example, having a clear incident timeline, related alerts, historical activity, and threat intelligence information available in one place would make investigations easier. I believe these improvements would make day-to-day SOC operations smoother and allow analysts to focus more on proactive threat hunting and other complex investigations.

Pricing and Cost Advice

"The MSP model we were in needed some work. It was not MSP-friendly, which means that an MSP is going to say that I have five thousand endpoints that I will eventually get to you, but for now, we're gonna start moving and let me purchase a thousand. So, you buy a thousand licenses, and you ramp up to that thousand. When you're ready to move on, you buy the next how many. That's the way an MSP likes to work, whereas it was a little bit different with eSentire. You had to purchase specific amounts for specific customers. It wasn't very friendly when it came to pricing for MSPs."
"It was cost-effective and not very expensive. Licensing was on a yearly basis. There were no additional costs to the standard licensing fee."
