Trellix Network Detection and Response is somewhat stable but there is a bit of downtime sometimes during the off-hours.
Associate Cybersecurity Analyst at a tech vendor with 10,001+ employees
 

Room For Improvement

Microsoft Defender for Identity needs improvements in alert accuracy, UI/UX, asset integration, automation, anomaly detection, and third-party integration.
Trellix users desire better firewall integration, AI, reporting, UI, customization, threat intelligence, onboarding, documentation, support, and automation.
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.
CyberSecurity Engineer | Information Security Management at Self Employed
One improvement I would recommend is the integration of an admin application within Teams, allowing easy access to attack information on a mobile platform.
Owner at Alopex ONE UG
Reducing false positives is something we've been working on with Microsoft.
Cloud Security & Governance at a financial services firm with 10,001+ employees
There should be improvements in AI intelligence, faster decision-making, and a more responsive technical support team.
Information Security Engineer at Nhq Distribution Ltd
It would be best if Trellix Network Detection and Response sensors were converted into a next-generation firewall with built-in capabilities for routing, switching, and Layer 7 functionality, as most next-generation firewalls today include these features.
Network & Security Lead at Net-International
Regarding needed improvements for Trellix Network Detection and Response, there is always room for enhancement in terms of AI capability to include proactive triggers based on historical data, enabling AI to learn patterns and detect threats before they manifest.

Setup Cost

Microsoft Defender for Identity pricing aligns with E5 licenses, offering value in hybrid setups but can be costly at scale.
Trellix NDR is seen as pricey yet valued for quality, with customers desiring more cost-effective options despite reliability.
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.
CyberSecurity Engineer | Information Security Management at Self Employed
Ensuring a fair price according to market standards.
Owner at Alopex ONE UG
From an organization perspective, using E5 licenses is value for money, especially if Azure and Office 365 are already in use.
Cloud Security & Governance at a financial services firm with 10,001+ employees
My experience with the pricing, setup cost, and licensing of Trellix Network Detection and Response is that they are very good and affordable for the customer range.
Network & Security Lead at Net-International
The price for Trellix Network Detection and Response is reasonable.
IT Manager at Gigabit Technologies Pvt Ltd
I am sure the ROI was definitely fine for this because we were using this tool for three years.

Valuable Features

Microsoft Defender for Identity enhances threat detection and security integration, offering streamlined investigation with automated alerts and behavioral analytics.
Trellix Network Detection excels in threat detection, malware analysis, and integrates seamlessly with existing security tools for real-time response.
We receive an advance report of risky users, allowing us to take preemptive action before an attack causes damage to organization details.
Instrumentation Engineer at Toyo Engineering Corp
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.
Owner at Alopex ONE UG
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.
Cloud Security & Governance at a financial services firm with 10,001+ employees
Per day we used to have 70 to 80 alerts and those could be reduced up to 40 to 30 a day. This is almost a 40 to 50% decrease.
Associate Cybersecurity Analyst at a tech vendor with 10,001+ employees
Trellix Network Detection and Response has positively impacted my organization by addressing performance issues, specifically by offloading heavy traffic inspection and SSL inspection through sensors due to the limitations of the firewall.
Network & Security Lead at Net-International
Visibility is very important as it empowers users to understand what is happening; therefore, detection is one of the strongest features of Trellix Network Detection and Response.

Featured Reviews

Peter Arabomen - PeerSpot reviewer
Security Engineer at Fidelity Bank Plc
Has supported hybrid identity management while integrating well with cloud directory services
The only challenge I have with Microsoft Defender for Identity is the latency. I may not put that entirely on Microsoft, because latency could be network related. At times when trying to authenticate, the prompt is delayed. We tried implementing passwordless authentication, especially for on-premises workloads, but we haven't been able to achieve that. Passwordless authentication is part of the identity functionalities, particularly when it comes to enforcing passwordless for on-premises workloads. In terms of improvements, you can't create OUs on Azure AD. Regarding giving users privileges on what they can do across different OUs, I haven't seen that feature on Microsoft Defender for Identity. Microsoft Defender for Identity needs to be able to plug into third-party applications that are not Microsoft. For instance, with a human resource application used to manage users and leave requests, when staff leaves the organization, they are first exited from that application before AD. Integration between Azure AD and third-party applications would allow automatic syncing when removing staff. The initial setup of Microsoft Defender for Identity is not hard. However, setup is one thing, and getting value from the application end-to-end is another. It can be set up and running from the first day but not functioning optimally. Initially, when we did the setup, it wasn't optimal. Over time, with continuous improvement, which we're still doing, we've gotten to a comfortable level, but there's still room for improvement.
Hassan Sheikh - PeerSpot reviewer

Integrated sensors have improved traffic inspection and now provide resilient east-west threat control
I believe Trellix Network Detection and Response can be improved by integrating machine learning into its detection response capabilities. Additionally, incorporating failover kits integrated into the sensors could be beneficial. It would be best if Trellix Network Detection and Response sensors were converted into a next-generation firewall with built-in capabilities for routing, switching, and Layer 7 functionality, as most next-generation firewalls today include these features. While Trellix Network Detection and Response sensors are highly capable, I think it would be advantageous to include features such as Layer 7 profiles, application profile filters, web filters, IDx, IP feature sets, signature detection features, and routing and switching capabilities all in one device. While the user interface of Trellix Network Detection and Response is very good, I suggest implementing a customizable dashboard. Additionally, there should be report generation for critical attacks and high alert severities, displayed graphically on the dashboard, and providing options to extract files in Excel format for better visibility.
