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

"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."
"The most important features of Vision One include visibility, AI integration, attack pattern analysis, predictive analytics, and centralized visibility and management across protection layers."
"The Trend hunting feature is beneficial, providing the opportunity to investigate and see what's happening, using frameworks such as MITRE ATT&CK to analyze logs."
"The telemetric report is the most valuable feature."
"The visibility over everything—over all systems or network and security—has improved us massively."
"Its threat intelligence sources enable it to automatically block domains known for command-and-control callbacks, effectively preventing attacks from those sources."
"TrendAI Vision One provides comprehensive insight into user behavior, dark web login monitoring, and open vulnerabilities, allowing us to see everything from a single platform, which simplifies security operations and reduces complexity."
"Trend Vision One's most valuable feature is its endpoint firewall rules."
"TrendAI Vision One is the best for AI-driven security, which is a very good point of the TrendAI Vision One console."
 

Cons

"The integration is not as seamless compared to competitors like Palo Alto."
"Further integration across different Microsoft products would be an improvement."
"With Microsoft, support is always crazy, it's not easy to get support."
"It is costly. It is not that affordable for a small organization."
"The scalability of TrendAI Vision One would be around a six; it is appropriate for smaller companies, but for bigger ones such as Nike, I would say it would not fit as well."
"The centralized dashboard has room for improvement."
"Improving the user interface would be helpful—it can be confusing, especially if you do not use it daily."
"The information captured by Trend Vision One needs to be more detailed."
"While blocking an IP address restricts access for 30 days, it eventually becomes accessible again."
"The price could be lower."
"Trend Micro XDR is expensive, and you have to pay for it yearly."
 

Pricing and Cost Advice

Information not available
"Competitors offer comparable solutions at slightly lower prices, so Vision One has room to reduce its pricing by 15 percent, given that Trend Vision One charges approximately $10 per endpoint."
"When I compare it to its peers that can do the same, it is cost-effective."
"I feel that Vision One is a bit expensive. As for the pricing or licensing, I would rate it a seven out of ten."
"Vision One's pricing is extremely competitive. They're probably the lowest-cost provider that has this feature set."
"It's relatively well-priced."
"Trend Micro XDR is expensive, and you have to pay for it yearly."
"Trend Micro recently switched from a license-based pricing model to a credit system, which caused some initial frustration during my renewal."
"It would be nice if it was a little bit cheaper, but I think it has a fair price. It is comparable to others in the market."
