Sr. Manager, Security Engineering at a financial services firm with 501-1,000 employees

The transparency of data in the platform is perfect: You see everything as they are seeing it

Their Zero Trust Analytics Platform (ZTAP) engine, which is kind of their correlation engine, is by far and away one of the best in the business. We can filter and utilize different lists to build out different alerts, such as, what to alert on and when not to alert. This engine helps reduce our number of alerts and false positives. The service's Trusted Behavior Registry helps the provider solve every alert. The way that they have it built out is very intelligent. The way every alert comes in, it gets triaged one direction or another. If it is already a false positive, then it is still getting addressed and reviewed on a regular cadence. Also, true positive alerts get escalated to the appropriate personnel. Its mobile app is great. The ability just to be able to quick reference and see what's coming in when you're on the move or go. You don't always need to have your computer or laptop handy, because you can operate it just from the mobile app. It can communicate with analysts, which is great. The mobile app is great at affecting the efficiency of our security operations. Those guys are using it throughout the day, whether that be at the office, home, or off hours. Typically, they triage from the mobile app. Then, if an escalation needs to be done on a computer, they will pull out a computer. We were on the original UI for a few years, so the updated UI has been a refreshing change. It has significantly more ability to filter and translate data, then load that data. It is rather intuitive to click through for some of our junior analysts or interns, especially as we are starting to onboard and teach them different aspects of the security operations team.

Has supported clients in managing incidents through clear pricing and hybrid deployment options

What really stands out about Microsoft Defender Experts for Hunting is that it's easy to use. The cost is clear, and the pricing is transparent. The onboarding of the product on the customer's environment is straightforward. We can use it in a hybrid environment, in the cloud, or on-premise environment. This is the main advantage regarding this product. If it's configured correctly, everything will be good, resilient, and secure, which supports threat mitigation efforts depending on the configuration on the tenant and the parameters on Microsoft Defender Experts for Hunting. Threat intelligence updates have some impact on our overall security posture. They give us external eyes regarding threat actors, which is good. It's very helpful to enrich the SIEM, which is Microsoft Sentinel. It's a good feature that we can include threat intel on the product.

Quotes from Members

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

Pros

"After a year of using the service, our expectations have been met in terms of services delivered on time, on budget, and on spec."

"The most valuable feature of their service is their tuning... If we were getting 1,000 alerts a day without them, they tune it until they know what to do for 999 of them, and one will make it through to us per day. That tuning is the most valuable part of their solution."

"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."

"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."

"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."

"Outside of using the platform to manage alerts, the feature of the service that we get the most value from is being able to reach out to them and say, "Hey, we might go buy a SIEM," for example. They give us their overview of what's out there, what they've dealt with, what they integrate with, and what that looks like. That's been pretty powerful over the years for us."

"When I start thinking about if I were to try to light up a SOC, which I've done before and I have no interest in doing, it could be a million dollars a year or more to do that, and for what I am paying them for the managed fees, it's a steal."

"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."

More CRITICALSTART pros

"Easy to use is what my customers say is the biggest benefit of Microsoft Defender Experts for Hunting for them."

"The best feature of this solution is that it is an integrated and comprehensive solution for the entire Microsoft ecosystem."

"The solution helps to detect some suspicious items for us and our clients."

"What really stands out about Microsoft Defender Experts for Hunting is that it's easy to use, the cost is clear, and the pricing is transparent, with straightforward onboarding in hybrid, cloud, or on-premise environments."

"Microsoft Defender Experts for Hunting helps my customers detect or prevent emerging threats that are not yet published but Microsoft has visibility into."

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."

"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."

"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 and I hate it."

"They could dig a little bit deeper into the Splunk alerts when they feel like they need to be escalated to us."

"It costs a lot for what we felt comfortable to spend."

"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."

More CRITICALSTART cons

"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."

"The price of the solution is costly, which I find significant."

"There is a lot of change in a small period. This might not be helpful for IT administrators and users."

"As a partner, Microsoft Defender Experts for Hunting could be improved by getting earlier threat detection signals so we could proactively research on our own end and help support a campaign to raise awareness as well as proactive response."

Pricing and Cost Advice

"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 of other services was so insane that they weren't even an option."

"It costs a lot for what we felt comfortable to spend."

"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."

"I've told CRITICALSTART that I think the managed service they provide is cheaper than it should be. It's a really good deal."

"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."

"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."
