Trellix Network Detection and Response is stable and reliable, with consistent performance and high user satisfaction despite occasional minor issues.

We do not see any issues with the stability of Microsoft Defender for Identity.
Having recently started using it, reliability is affirmed, but manual investigation is often performed to verify if alerts identified by auto-remediation are accurate.
 

Room For Improvement

Microsoft Defender for Identity users seek improved cloud integration, user-friendly features, better support, and streamlined processes for enhanced threat management.
Trellix Network Detection needs improved customization, integration, AI capabilities, support services, and a more user-friendly interface at reduced pricing.
If Microsoft could develop a feature that indicates when impossible travel is caused by VPN connections, it would prevent unnecessary password resets and session disruptions, especially for VIP users in organizations.
Reducing false positives is something we've been working on with Microsoft.
One improvement I would recommend is the integration of an admin application within Teams, allowing easy access to attack information on a mobile platform.
There should be improvements in AI intelligence, faster decision-making, and a more responsive technical support team.
 

Setup Cost

Microsoft Defender for Identity is cost-effective with E5 licenses despite complex pricing and competitive against other security solutions.
Trellix Network Detection is costly but effective, with yearly licensing, discounts, and competitive pricing against some competitors like Palo Alto.
If they can reduce the costs, organizations will be happy, and it will compensate for using the Azure environment, which is more expensive on the infrastructure as a service side.
the Microsoft Defender Suite is quite expensive, especially when integrated into Sentinel.
From an organization perspective, using E5 licenses is value for money, especially if Azure and Office 365 are already in use.
 

Valuable Features

Microsoft Defender for Identity integrates with Azure to offer comprehensive threat detection, identity protection, and advanced real-time security insights.
Trellix excels in threat protection with AI-driven analysis, automation, and enhanced visibility, benefiting security operations and incident management.
We receive an advance report of risky users, allowing us to take preemptive action before an attack causes damage to organization details.
Based on the detection of incidents, we can prevent issues, and if there are any identity-related alerts, they are prevented through a conditional access policy.
The seamless integration with other Microsoft solutions within our Microsoft-centric environment is also a major advantage.
Trellix NDR provides an essential defense by automatically responding to network incidents that firewalls may not catch.

ROBERT-CHRISTIAN - PeerSpot reviewer
Integration within the ecosystem enhances collaboration and automates functionalities
The integration into the Microsoft Defender ecosystem is the most valuable feature of Microsoft Defender for Identity. It fits very nicely with all the other Defender tools, allowing for excellent collaboration among them. It also fits seamlessly into Microsoft Sentinel SIEM. Furthermore, Microsoft security solutions can save time as they allow the automation of numerous functionalities, and the reporting inside the Microsoft ecosystem is commendable.
BiswabhanuPanda - PeerSpot reviewer
Offers in-depth investigation capabilities, integrates well and smoothly transitioned from a lower-capacity appliance to a higher one
The in-depth investigation capabilities are a major advantage. When the system flags something as malicious, it provides a packet capture of that activity within the environment. That helps my team quickly identify additional context that most other tools wouldn't offer – like source IP or base64 encoded data. We can also see DNS requests and other details that aren't readily available in solutions like Check Point or others that we've tried. The detection itself is solid, and their sandboxing is powerful. There's a learning curve – you need a strong grasp of OS-level changes, process forking, registry changes, and the potential impact of those. But with that knowledge, the level of information Trellix provides is far greater than what we've seen elsewhere. The real-time response capability of Trellix has been quite effective, although it's not very fast. The key is this solution's concept of 'preference zero.' They don't immediately act on a zero-day. For example, the solution has seen a piece of malware for the first time. It'll let it in, then do sandboxing. Maybe after four or five minutes, it identifies that specific file's DNX Secure Store as malicious. At that point, they update the static analysis engine, and it gets detected if anything else tries to download the same file. There is that initial 'preference zero' concept, like with Panda. You may not hold traffic in the network. That's standard in the industry; we don't do much about it. To address that, we also have endpoint solutions. We use SentinelOne in our environment, which helps us identify threats like Western Bureaus and others.
