Protect on-premises and hybrid environments with advanced threat detection and seamless integration
Our Active Directory implementation is a hybrid one. The advanced threat protection is one of the strengths of Microsoft Defender for Identity, as it utilizes user and entity analytics and can detect indicative attacks. It identifies lateral movements, privilege escalations, and alerts on potential attacks. The tool is also used for security posture assessment. The seamless integration with other Microsoft solutions within our Microsoft-centric environment is also a major advantage.

Has unified our IT teams by providing clear visibility into network vulnerabilities and accelerated remediation with real-world attack testing
One of the things that we've shared with Horizon is just the reporting. They've made a lot of changes over time, but when examining computers, most average normal people don't look at a computer and identify it as 114.82.117.180. They identify it as 'the printer for accounting.' When many of the reports give the very detailed technical IP address or serial number, that's really not helpful for anyone other than the person, the hands-on person that's trying to remediate it. All the managers, all the leaders, having information in that format isn't helpful. Being able to have information about what those devices are would be very helpful. There's a technical reason they can't just have an easy button because some people have really complicated networks. When examining things for the average company, the average executive, that 114 number, there's only one of those. But if examining an AT&T or a Walmart, it isn't unique. They haven't solved that problem. But for the 90% of companies, being able to have just a human readable name for all devices on your network in all of the reports all of the time would be the most beneficial.

Quotes from Members

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

Pros

"In the security portfolio that we manage, Microsoft Defender for Identity is very important because it is the professional service that we sell the most."
"Defender for Identity has not affected the end-user experience."
"I recommend Microsoft Defender for Identity because it is easy to implement."
"Microsoft Defender for Identity provides excellent visibility into threats by leveraging real-time analytics and data intelligence."
"The basic security monitoring at its core feature is the most valuable aspect. But also the investigative parts, the historical logging of events over the network are extremely interesting because it gives an in-depth insight into the history of account activity that is really easy to read, easy to follow, and easy to export."
"The solution’s alerting is fairly efficient."
"The best feature is security monitoring, which detects and investigates suspicious user activities. It can easily detect advanced attacks based on the behavior. The credentials are securely stored, so it reduces the risk of compromise. It will monitor user behavior based on artificial intelligence to protect the identities in your organization. It will even help secure the on-premise Active Directory. It syncs from the cloud to on-premise, and on-premise modifications will be reflected in the cloud."
"Microsoft Defender for Identity helps me automate routine tasks and find alerts that I set up to receive, so it helps me get where I'm trying to go easier and faster."
"I rate the stability of the NodeZero Platform a ten out of ten."
"After the third party conducts the pen test, The NodeZero Platform is run, and it finds the same things they found and sometimes a few other things that they did not even identify."
"Honestly, it's one of the most transformational technologies we've implemented in our company."
"The NodeZero Platform's real attack capabilities help in identifying vulnerabilities on our on-prem systems because it provides actual vulnerabilities by attacking our systems."
"My favorite feature about The NodeZero Platform is that it's autonomous, and it truly delivers on that promise—it can be set and forgotten while it performs its tasks, and it does exactly what it claims to do."
"For us, The NodeZero Platform is literally the single best security solution we have because the way that it works is we're able to scan every part of our network, both internally and externally, and then get completely actionable feedback that doesn't matter if it's for an application developer or a network admin."
"The NodeZero Platform is amazing; what I love most about it is that it's automated and comparable to the manual pen testing we did with a third-party company, but with the added benefit of unlimited retesting to validate fixes."
"We experienced a threat that could have severely crippled us, but we were able to shut it down before it escalated, thanks to internal vulnerability testing and addressing critical vulnerabilities using their tool."
 

Cons

"One area that needs improvement is the number of alerts generated, leading to alert fatigue."
"When the data leaves the cloud, there are security issues."
"Fixing the solution isn't very seamless."
"We observe a lot of false positives. Sometimes, when we go for a coffee break, we lock our screens. Locking the screen has a separate Windows event ID and sometimes I see it is detected as a failed login."
"The impact of the sensors on the domain controllers can be quite high depending on your loads. I don't know if there's any room for improvement there, but that's one of the things that might be improved."
"The solution could be better at using group-managed access and they could replace it with broad-based access controls."
"An area for improvement is the administrative interface. It's basic compared to other administrative centers. They could make it more user-friendly and easier to navigate."
"One improvement I would recommend is the integration of an admin application within Teams, allowing easy access to attack information on a mobile platform to promptly alert affected users and their friends."
"Sometimes even their support doesn't know why we're seeing certain issues."
"I think The NodeZero Platform could improve by leveraging GPUs for password cracking, which would be pretty good."
"One of the areas where improvement is needed is in the visibility and reporting for large enterprises."
"You need to be cautious about what it scans, as it could potentially cause issues."
"The only issue we’ve encountered is that sometimes the scans take a long time to complete."
"They've added a chatbot which isn't particularly useful, but when it can't answer questions, it forwards messages to human support."
"The areas for improvement for The NodeZero Platform involve integration and automation. It would be beneficial if it could integrate directly with vulnerability management tools that would allow the platform to automatically import data, identify vulnerable systems, and test targets immediately, potentially even enabling automated feedback loops for rescanning since the process is currently manual."
"The reports are quite useless."
 

Pricing and Cost Advice

"You won't be able to change your tenants from where you deploy them. For example, if you select Canada, they will charge you based on Canadian pricing. If you are also in London, when you deploy in Canada, the pound is higher than Canadian dollars, but your platform resources are billable in Canadian dollars. Using your pounds to pay for any of these things will be cheaper. Or, if you deploy in London, they will charge you based on your local currency."
"Defender for Identity is a little more expensive than other Microsoft products. Identity and Microsoft Defender for Cloud are both a bit costly."
"Microsoft Defender for Identity comes as part of the Microsoft E5 licensing stack."
"The product is costly, and we had multiple discussions with accounting to receive a discounted rate. However, on the open market, the tool is expensive."
"It is very affordable considering that other SIEM solutions are much more expensive and have many more licensing restrictions and fees."
