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.

Ensuring long-term reliability while seeking internal email management enhancements
Prisma is a commercial name of the firewall now, but we don't work with the cloud product. Only our company is using it and we do not recommend it to customers. For us, it's transparent because it's a cloud product, so we don't really know the version as it's always updated. We have not had any problem, but it's difficult to report on what's going on because some days they can wash out perhaps 100 mails, and then it's difficult to say how many attacks you have reached. The right email has been washed out and then nobody has complained. We do not use the Threat Visualization feature; as we are in MX, the mail is washed out before it is in the mail inbox of the user, thus avoiding any problem requiring a reservation. In fact, there is no integration with existing security frameworks. The only problem we can have is that as we have no API interface, there is no inspection of internal mail. I rate Trellix Advanced Threat Defense a nine out of ten.

Quotes from Members

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

Pros

"The most valuable features of Microsoft Defender for Identity are the simulations; whenever something happens, it provides complete step-by-step process details, including the hierarchy, how it happens in the environment, and the lateral movement, which is amazing."
"One of our users had the same password for every personal and company account. That was a problem because she started receiving phishing emails that could compromise all of her accounts. Defender told us that the user was not changing their password."
"The solution offers excellent visibility into threats."
"I would rate Microsoft Defender for Identity at nine out of ten."
"Defender for Identity has not affected the end-user experience."
"We use AD Connect to sync on-premises AD to Azure AD, and so far, it has been effective."
"I recommend Microsoft Defender for Identity because it is easy to implement."
"The most valuable feature is its hybrid artificial intelligence, which gathers forensic data to track and counteract security threats, much like the CSI series in effect."
"Provides good exfiltration, and is an all-in-one product."
"The most valuable features are the administration console and its detection and response module."
"It stops in excess of twenty-five malware events per month, all of which could be critical to the business."
"I recommend this solution because of its ease of use."
"It is very scalable."
"Its greatest strength is the DXL client which can rapidly disseminate attack information to all clients via the McAfee Agent instead of going through the ePO server."
"The fact that in 10 years, we have had no problem is the most valuable feature for us; it's really a washing machine, but the only problem we face is that it's difficult to report on this product."
"It is stable and reliable."
 

Cons

"The areas of Microsoft Defender for Identity that can be improved include its cost, which is quite expensive when integrated into Sentinel. Additionally, there is room for improvement in its integration with non-Microsoft applications and systems."
"Microsoft Defender for Identity does not save me time, but I think it is the way that I secure the data."
"Defender for Identity gives us visibility, but we often get false positives from Azure that take us down the garden path. We go through 30 incidents each day and most of those are false positives or benign positive alerts. Occasionally, we get true positive alerts."
"One area that needs improvement is the number of alerts generated, leading to alert fatigue."
"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."
"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."
"The solution should provide more detailed data regarding anomaly detections."
"I would like to be able to do remediation from the platform because it is just a scanner right now. If you onboard a device, it shows you what is happening, but you can't use it to fix things. You need to go into the system to fix it instead."
"The only problem we can have is that as we have no API interface, there is no inspection of internal mail."
"This solution needs to be made "cloud ready"."
"Make the ATD system a part of the whole product and take the whole thing onto the cloud. While it is there already, it is not to the same level as the on-premise version."
"We'd like them to be better at dealing with script threats."
"I would like to see future versions of the solution incorporate artificial intelligence technology."
"There could be a tool that automatically updates all-new Microsoft IPs, which are available for free to connect to the client."
"Lacks remote capabilities not dependent on the internet."
"The initial setup was industry standard complex. It takes awhile and has a lot of planning involved. It could be simplified with product redesign."
 

Pricing and Cost Advice

"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."
"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."
"Microsoft Defender for Identity comes as part of the Microsoft E5 licensing stack."
"Defender for Identity is a little more expensive than other Microsoft products. Identity and Microsoft Defender for Cloud are both a bit costly."
"The product is expensive, but it is better than the rest of them in the industry."
"Our licensing fees for this solution are approximately one million dollars per year."
