Saves my team time and alert fatigue, allowing us to concentrate on more important things
The Trusted Behavior Registry helps resolve alerts in the sense that CRITICALSTART is doing a lot of that initial triage for me. Out of a given 500,000 events and alerts, for example, that come through, they're taking out 495,000 of them. That only leaves me with a subset of that to actually have to triage, and that's where it benefits us. They take care of Tier-1 and Tier-2 triage. And the new mobile app is awesome. It is one of the best I've ever seen. It's much better than its predecessor. It's more intuitive, a whole lot easier to navigate and get where you need to go. It's less repetitive and just generally easier to use. It allows me to not have to be sitting at my computer all the time. I can be on my phone or tablet or wherever I'm at. It makes it a lot easier to answer tickets and do that kind of thing. Also, the intuitiveness of the updated user interface for the service is spot-on. It is much easier to navigate, and know where to navigate, in the newer interface. I've never had an issue with responsiveness. It's very quick and doesn't sit there and chug on anything. It's fast, it's efficient. It has enabled our SecOps team to take action faster because if you have multiple ways of connecting to it and actually getting your alerts answered and taking care of things fast, it is extremely helpful. All the information that you need to make a determination is usually in the alert itself that comes through the Zero-Trust Analytics Platform (ZTAP). I don't find myself going back to the app itself very often. That still happens, but not as often. The ability to flow the information forward, from the alert standpoint, helps me because it saves me from running back to get the information. It's improved my efficiency. Finally, there haven't been any data sources that the service wasn't able to integrate with.

Thorough incident analysis and seamless integration enhance security efforts despite some room for improvement
We tried the proactive threat hunting feature, but it was not a good experience with Microsoft Defender Experts for Hunting. It created more trouble than expected with false positives and non-expected answers. We opened a support case with Microsoft and had an engineer work with our customer. They fixed it, but it was definitely not a good experience for the customer. The integration capabilities of Microsoft Defender Experts for Hunting with existing security tools are quite easy because it's by design. It's only a button that, if you pay for the feature, you will have the ability. The value of detailed incident reports varies depending on the customers. Some say it helps in investigating, while others find it very interesting for proactive remediation. Potential users should try Microsoft Defender Experts for Hunting to form their own view and improve their security posture. It can help address the lack of internal personnel if needed. Overall rating: 8/10

Quotes from Members

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

Pros

"There is a team of people who monitor our traffic and processes 24/7, so if anything raises a flag or alert, it will escalate back to me right away. That's the most incredible part: Humans working behind the scenes 24/7 to monitor our networks."
"I also use their mobile app. It's very easy to use and very convenient to be able to respond to alerts wherever you are. I love the app. You can respond and communicate, per ticket, with their SOC in near real-time. The response is very quick."
"Customer service and their response are phenomenal. I would give their customer support a nine point five (out of 10). Our easy access to their SOC analyst, sales team, and leadership team instills confidence in me that they are there for us 24/7."
"The new mobile app is awesome. It is one of the best I've ever seen. It's much better than its predecessor. It's more intuitive, a whole lot easier to navigate and get where you need to go. It's less repetitive and just generally easier to use. It allows me to not have to be sitting at my computer all the time. I can be on my phone or tablet or wherever I'm at. It makes it a lot easier to answer tickets and do that kind of thing."
"From where we were prior to going into them, the service has increased our analysts’ efficiency to the point that they can focus on other areas of the business. It gives me the ability to allow analysts to do Level 3 and 4 work and stay out of the weeds of the alerts, where you tend to get alert fatigue. The service takes care of much of the Tier 1 and Tier 2 triage. It is more effective than what we had been used to, because it allows the filtering of Level 1 and Level 2 type alerts to be taken care of. This leaves less for us to handle, which is a good thing."
"The way that the user interface presents data enables our team to be able to make decisions significantly quicker, rather than have to dig into the details or go back to the original tools."
"My impression of the transparency of the data is that it has good detail. It allows you to see how many events have come in, how many of those events have made it down to their analysts to review, and then however many from their analysts to be able to close out, have been able to been escalated to us. It's a good metric that we can share with my management. They see the value of what the SOC is bringing on top of what my team is already doing."
"The main difference between the other options and this one is the quality of the personnel within the SOC. It's their knowledge and depth and the way they handle customers."
"The solution helps to detect some suspicious items for us and our clients."
 

Cons

"The updated UI is actually pretty bad. Regarding the intuitiveness, it is fairly easy to use, but the responsiveness, on a scale of one to 10, is a one. It's really poor performance."
"In terms of responsiveness, when I open up an alert, sometimes it takes a bit of time to load. However, it only happened once or twice."
"It has frustrated us that they don't have a native Slack integration, because most things do now. That's something we've asked for, for years, and it just doesn't really seem like it's a priority."
"They just did a user interface overhaul to the website portal that you use for troubleshooting tickets. The old one was fine. The new one is not intuitive..."
"There is room for improvement with the new UI, and that's about it. I would like to see a more intuitive design."
"The only thing I can think of that I would like to see, and I'm sure they could work this into a service pretty easily, is not only alerts on issues that are affecting my company, but some threat intelligence of a general nature on what's out there in the environment. That might be a nice add-in."
"The UI has become slower but it's not something I would call them out on."
"The biggest room for improvement is not necessarily in their service or offering, but in the products that they support. I would like them to further their knowledge and ability to integrate with those tools. They have base integrations with everything, and we haven't come across anything. They should just continue to build on that API interface between their applications and other third-party consoles."
"The solution’s user interface could be improved."
"We tried the proactive threat hunting feature, but it was not a good experience with Microsoft Defender Experts for Hunting. It created more trouble than expected with false positives and non-expected answers."
 

Pricing and Cost Advice

"I've told CRITICALSTART that I think the managed service they provide is cheaper than it should be. It's a really good deal."
"It costs a lot for what we felt comfortable to spend."
"There are contractual penalties if their SLAs are not met. This commitment was very important in our decision to go with this service, because not having downtime is extremely important to us. The providers has not missed an SLA in the 18 months that I have worked with them."
"The pricing has always been competitive. They have always been good to us. They will make it a fight. They don't try to hide anything; it's always been fully transparent and well-worth what we pay for it."
"As far as the expense goes, it's very competitive pricing and the services you get are almost like you have a person on your team."
"Overall, for what I'm paying for it, and the benefit I'm getting out of it, it is right where it needs to be, if not a little bit in my favor. For what it costs me to actually have this service, I could afford one internal person to do that job, but now I have a team of 10 or more who are doing that job, and they don't sleep because they work shifts."
"The pricing of other services was so insane that they weren't even an option."
