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.
Jose Vargas - PeerSpot reviewer
Agente De Servicios Técnicos at a computer software company with 11-50 employees
Has improved threat detection workflows and supports seamless customer monitoring
The best features Trellix Network Detection and Response offers include very good threat detection, and I believe that it is one of the best XDR tools. For example, ePO and XDR components are very comfortable and similar to many other tools for this type of monitoring, and I have received very good feedback for this tool. What makes Trellix Network Detection and Response stand out for me compared to other tools is the way you can detect threats. It is very easy and comfortable to use, and the detection shows clearly on the screen, which is very easy to understand. Regarding the features, I think that the integration with other platforms is very comfortable with the customer because we can integrate it with any switch or firewall, and it is comfortable to add this tool. Trellix Network Detection and Response has positively impacted my organization as I have improved my knowledge about detection and response. I have already used some other tools such as CrowdStrike and Umbrella, but Trellix is one of the best that I have tested. I believe that for my organization, Trellix has helped a lot with detection and supported our customers effectively. Trellix Network Detection and Response is a great tool that integrates with a lot of security tools such as Palo Alto, which is a good firewall. If you have these types of tools, your organization would benefit greatly.
