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.

AI-driven SOC triage has transformed threat monitoring and keeps our security work focused
The best features UnderDefense offers include mostly triage in-context signals read together across my stack, where one finding replaces many separate checks. A good thing too is its false positive suppression, as I do not get false notifications. Normal activity such as traffic spikes during customer events is recognized and documented, and only the unusual cases reach me. It has full-time support 24/7 with proactive reports, and monitoring runs around the clock. Reports and alerts come to me without even noticing or asking, so it is very useful. My team sees what happened without having to chase it. I find the proactive reporting and 24/7 support to have definitely made a real difference. Proactive reports mean I hear about what happened without having to ask, so I know the state of things at the start of the day, and 24/7 support matters most for traffic spikes and other events outside busy working hours, as I get an answer when I need one without keeping someone on call just in case, saving me a lot of time. Together, they let my team stay on infrastructure work and step in only when a decision is needed. Regarding UnderDefense's AI capabilities, I think the governance and security is the best there is, as the decisions that matter stay with my team and each finding is documented, allowing me to review afterwards how a conclusion was reached. That control and traceability is what I need from AI in a security role. The accuracy and reliability of UnderDefense's AI output is accurate and steady, as findings have matched what I saw when I checked them, and the pattern assessments are consistent, especially during large traffic events or spikes, which is when I depend on them most. When a case needs judgment, the reasoning is there so I can confirm it myself.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The Managed Detection and Response (MDR) feature was really good and most valuable. We were handling very sensitive data, and we needed a quick response in real-time, which eSentire provided. It was also cost-effective, and their SOC team was very responsive."
"Being able to sleep well at night knowing that eSentire is guarding everything that goes in and out of your network was also a good ROI."
"The managed detection response (MDR) product was the most valuable."
"Routine signals are handled and documented, and only cases that need a human decision reach my team, allowing engineers to spend their time on infrastructure hardening instead of log digging."
"Every morning we look at a short list of cases that matter instead of a long list of raw alerts, and each case comes with the full picture, so we can decide in a few minutes whether it needs action."
"The linking, the filtering, and the readable reasoning each help on their own, but together, they allow a small security team to handle the volume our platform produces without losing sight of the cases that matter."
"UnderDefense Gen AI SOC flags behavior that breaks from an account's own baseline, lays out which signals triggered the alert and why it reads as different from normal activity, and helps our team decide within the same day whether we are seeing a legitimate big campaign push or a compromised login."
"UnderDefense groups it into one alert with the caller, the endpoint, and the usual pattern, which allows us to contact the customer the same day with facts in hand."
 

Cons

"Its GUI can be a lot better."
"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."
"UnderDefense could improve in onboarding, which takes some dedicated time because the baseline for our high volume upload events needs to be set up first."
 

Pricing and Cost Advice

"It was cost-effective and not very expensive. Licensing was on a yearly basis. There were no additional costs to the standard licensing fee."
"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."
