Having recently started using it, reliability is affirmed, but manual investigation is often performed to verify if alerts identified by auto-remediation are accurate.

The product updates and security updates are kept current, allowing us seamless integration with Trend Micro and getting daily updates and signatures without problems.
Senior IT Security Engineer at a financial services firm with 5,001-10,000 employees
 

Room For Improvement

Microsoft Defender for Identity needs improvements in alert accuracy, UI/UX, asset integration, automation, anomaly detection, and third-party integration.
Trend Micro Deep Discovery faces challenges with integration, scalability, support, pricing, and requires improvements in usability and network capabilities.
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
We have multiple components such as Deep Discovery Email Inspector for mail gateways, Deep Discovery Analyzer for sandboxing, and Deep Discovery Inspector, which serves as an IDS detecting malicious network traffic.
Senior IT Security Engineer at a financial services firm with 5,001-10,000 employees
The solution is not scalable as it is an agent product rather than a product designed for scalability.
Owner at Darcom
There is no dedicated team in India for giving support for Trend Micro Deep Discovery.
Director at Business Automation Indore Private Limited
 

Setup Cost

Microsoft Defender for Identity pricing aligns with E5 licenses, offering value in hybrid setups but can be costly at scale.
Trend Micro Deep Discovery [EOL] pricing is annual, node-based, varies by requirements, and opinions differ on its competitiveness.
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
I do not consider it an expensive tool; its price is justified based on the capabilities that we receive when compared to another mail gateway or other vendors.
Senior IT Security Engineer at a financial services firm with 5,001-10,000 employees
The solution is very expensive.
Owner at Darcom
Overall, the licensing cost of Trend Micro Deep Discovery was not on the higher side earlier, but now, since the competition has increased, we need to think about the prices.
Director at Business Automation Indore Private Limited
 

Valuable Features

Microsoft Defender for Identity enhances threat detection and security integration, offering streamlined investigation with automated alerts and behavioral analytics.
Trend Micro Deep Discovery provides real-time threat detection, seamless integration, scalability, and user-friendly interface for comprehensive network protection.
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

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.

Has improved email security through advanced filtration and timely threat detection
I work with Trend Micro Apex One. I have used the Deep Discovery's Sandbox analysis feature, and we utilize another appliance known as Deep Discovery Analyzer, abbreviated as DDA. This tool makes analysis for URLs and attachments contained in inbound emails, so whenever we receive an email with a URL or attachment, it will be analyzed by Trend Micro Deep Discovery Analyzer. In evaluating Deep Discovery's real-time visibility on network traffic, it is important to note that we applied our Deep Discovery Analyzer for Trend Micro to conduct sandboxing specifically for email channels only, and we do not utilize it for network channels. For network channel sandboxing, we use a solution called FortiAnalyzer, which belongs to another team called network security. I assess Deep Discovery's effectiveness in identifying sophisticated attack patterns by looking at how it handles high traffic loads, and how effectively it can use its instances and images to analyze numerous URLs and attachments simultaneously. Additionally, I evaluate its ability to maintain round-robin or load balancing across different analyses without leaving samples queued for analysis. The performance is critical when the product updates for signatures are up-to-date, as this aids in the detection and classification of URLs and attachments without delay in the analysis process. On a scale of one to ten, I rate Trend Micro Deep Discovery a nine.
