Enhanced visibility and exposes vulnerabilities but needs more integration
I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…

Built faster threat response and improved visibility with real-time monitoring and flexible deployment
TrendAI Vision One allows us to monitor attacks in real time, which is a significant benefit. We can quickly see where the attack is coming from. TrendAI Vision One enables us to use different products with a flexible license. For example, if a customer is using endpoint security and wants to switch to another solution, they can instantly use a different Trend Micro product, such as email. TrendAI Vision One has helped to reduce the time to detect and respond to different threats, as it can respond to attacks very quickly. With playbook templates, in cases of recurring attacks, responses can be made quickly using predefined playbooks. TrendAI Vision One has helped to reduce noise from false positives. There have been false positives before, but it was due to the customer not telling us which app they were using. Best practice configurations must be applied properly to avoid such issues. TrendAI Vision One helps customers consolidate the use of security vendors and reduce silos by offering one platform for all product management.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"It seems to be better at protecting from cyberattacks."
"The most valuable feature is the network protection shield on every server, which isolates attacks and prevents our clients from being affected."
"TrendAI Vision One has helped to reduce the time to detect and respond to different threats, as it can respond to attacks very quickly."
"Our speed has increased significantly."
"I like that it is a comprehensive security solution with a lot of features. You can say XDR is an end-to-end security solution with endpoint security. It includes all your servers, networks, and other devices. The endpoint security solution does not cover this. Plus, machine learning and features like that are the main things in XDR solutions."
"The most valuable feature is how the stack fully integrates all components of a solution."
"We haven't had any issues with configurations or customizations."
"IPS is one of the greatest parts of Trend Micro, followed by Anti-Malware and then Web Reputation."
"The user interface is very good."
 

Cons

"Further integration across different Microsoft products would be an improvement."
"With Microsoft, support is always crazy, it's not easy to get support."
"The integration is not as seamless compared to competitors like Palo Alto."
"Trend Micro doesn't have the next-generation firewall."
"Technical support is not good. Their technical team should be more competent."
"To improve support, the company should streamline communication and reduce response times."
"They are planning on adding the Security Playbooks as a complete feature. In the preview mode, it is available; however, it is not released."
"Regarding the cyber risk exposure management capabilities, we did try to sell it, but there are too many competitors, and frankly speaking, there are other products better in the market."
"It would be better if it were more user-friendly. It would also be better if the implementation were more straightforward."
"A room for improvement in Trend Micro XDR is more visibility into the alerts. We do get alerts from the solution, but when we are away, we need to have more visibility."
"We've received some mild complaints that the documentation is sometimes not up to date."
 

Pricing and Cost Advice

Information not available

"Trend Micro XDR is reasonably priced for its value, comparable to other products like VMware Carbon Black."
"It's relatively well-priced."
"Trend Micro recently switched from a license-based pricing model to a credit system, which caused some initial frustration during my renewal."
"Its price is very decent. It suits our requirements."
"The pricing of the solution is okay. There is a need for me to look into the new pricing plan introduced by the solution recently."
"Trend Micro XDR is expensive but we got a good deal from Trend Micro."
