The quality of support is very good, but troubleshooting can take time due to complex setups and the need to provide many logs.
Generally, the support is more effective than other providers like Oracle.
Technical support needs improvement as sometimes engineers are not available promptly, especially during high-severity incidents.

Microsoft Defender for Identity is stable and reliable, though occasional sensor restarts occur, generally scoring 6-9/10 in stability.
Sentiment score
7.7
Trellix Network Detection and Response is stable and reliable, with consistent performance and high user satisfaction despite occasional minor issues.
Microsoft Defender for Identity is quite robust and built on Azure hyperscale infrastructure, with a 99% availability.
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 needs better integration, usability, and support, with improved detection and cost efficiency highlighted by users.
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 within E5, offering flexibility compared to standalone purchases or E3 add-ons.
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.
From an organization perspective, using E5 licenses is value for money, especially if Azure and Office 365 are already in use.
Ensuring a fair price according to market standards.

The integration into the Microsoft Defender ecosystem is the most valuable feature of Microsoft Defender for Identity.
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.
Trellix NDR provides an essential defense by automatically responding to network incidents that firewalls may not catch.

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.
