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."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"One of the features I like in Trend Micro XDR is that you can drill down on the root-cause analysis for anything you find on the solution. I also like that it works for detection purposes. Behavior analytics is also what I like most about Trend Micro XDR. I love that it has features such as behavior detection, program detection, and memory scanning. By default, the solution protects against spyware, apart from the normal virus scan. Smart Scan and DLP are also available in Trend Micro XDR which I like as well."
"We had previously deployed on-premises, and all we had to do was access the designated console and click a button to migrate all on-premises agents to cloud agents."
"Overall, we have managed to reduce our resolution time by approximately 99% due to our multiple teams working 24/7."
"Threat detection and response time has been reduced by 70–90%, risks are now identified within minutes instead of half an hour, false positives have decreased significantly, and the company now feels very secure."
"I'm satisfied with the level of coverage. The policies have been very useful and detailed."
"The setup is fairly simple."
"The most important features of Vision One include visibility, AI integration, attack pattern analysis, predictive analytics, and centralized visibility and management across protection layers."
"Trend Micro XDR is a comprehensive solution that is not overly complex to use or manage."
 

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 Vision One requires several enhancements for optimal performance."
"Trend Vision One has some usability issues."
"In new versions I would like to see better implementation of the reporting features, especially in regards to EDR visibility."
"I would rate their customer support a five out of ten. They sometimes do not give enough attention to the tickets."
"In comparison to Trellix, one disadvantage of Trend Micro is the DLP feature. Trend Micro has a light DLP, while Trellix offers a perfect DLP."
"The centralized dashboard has room for improvement."
"Stability can also be improved. Sometimes when we perform user management or when we go to log in to create the user, there will be some lagging on the network or it will automatically log out, and then we have to log in again on the web page."
"We've received some mild complaints that the documentation is sometimes not up to date."
 

Pricing and Cost Advice

Information not available
"Trend Vision One is an expensive product."
"Trend Micro's cost is higher than other solutions. That is the main reason why we need to switch to another solution."
"It is very good. The flexibility to temporarily exceed license limits when setting up new devices is helpful, as it allows us to ensure security before purchasing additional licenses."
"When I compare it to its peers that can do the same, it is cost-effective."
"The pricing is fair and not on the higher side."
"Trend Micro XDR is reasonably priced for its value, comparable to other products like VMware Carbon Black."
"The pricing is competitive, and the cost aligns with the features we receive."
"I do not have much visibility to it. It is definitely not a cheap product, but to my knowledge, it is out there with the big wigs in the industry, such as CrowdStrike, SentinelOne, and other EDR/XDR vendors. I had heard, and found out eventually, that their sales teams are very flexible, as more sales teams are."
