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

"CRITICALSTART makes us much more comfortable with knowing someone else is watching our data and our systems and knowing that professional security people are taking a look at any issues that do arise."
"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."
"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."
"In a given quarter, I get 589,000 security events and 584,000 of those get reduced by the service before they even get to me, so the alerts that actually come through to me end up being about 1,400 in that quarter, which is a 99.7 percent efficiency rate."
"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."
"It is a comfort to know that there is a team of professionals backing you up, especially in an area that you don't feel 100 percent comfortable."
"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."
More CRITICALSTART pros
"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."
"The best feature of this solution is that it is an integrated and comprehensive solution for the entire Microsoft ecosystem."
"Easy to use is what my customers say is the biggest benefit of Microsoft Defender Experts for Hunting for them."
 

Cons

"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 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."
"The UI has become slower but it's not something I would call them out on."
"There is room for improvement with the new UI, and that's about it. I would like to see a more intuitive design."
"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."
"The biggest room for improvement is not necessarily in their service or offering, but in the products that they support."
"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."
More CRITICALSTART cons
"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."
"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."
"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."
"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."
"It costs a lot for what we felt comfortable to spend."
