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.

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."
"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 workbench alerts provide valuable insights into attack chains and relevant information, while Observer techniques give a comprehensive overview of ongoing activities."
"ROI is absolutely achievable, especially with TrendAI Vision One and server TrendAI Vision One platform."
"I like XDR's workbench feature and observed attack technique. It generates an alert once certain conditions are met. For example, let's say there's a threat called malicious.exe being deployed on your system. It will generate an alert with information like the file path, location, hash, etc. You also see a relational matrix showing how that file was executed and which processes were installed."
"The zero-day vulnerability is valuable."
"The automatic EDR system that notifies us when something is wrong is valuable."
"We've found the pricing to be reasonable."
"They were one of the companies, early on, that spent a lot of time integrating their toolsets, and I was really impressed with that... the endpoint management system could reach out to the Deep Discovery system on the network and pick up something that it perceived as a suspicious object."
"Trend Vision One's most valuable feature is its endpoint firewall rules."
 

Cons

"Further integration across different Microsoft products would be an improvement."
"The integration is not as seamless compared to competitors like Palo Alto."
"With Microsoft, support is always crazy, it's not easy to get support."
"Trend Vision One requires several enhancements for optimal performance."
"There are limitations in terms of threat response actions."
"Results were delayed."
"The zero trust is a bit complicated compared to other parts of the solution."
"We'd like to see a few more integrations."
"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."
"For XDR threat investigation, there is not enough documentation about how to search for different keywords."
"The only downside to Trend Vision One is its complexity."
 

Pricing and Cost Advice

Information not available
"While the pricing and licensing for Trend Vision One are generally acceptable, the need to purchase additional features separately adds complexity."
"Vision One's pricing is extremely competitive. They're probably the lowest-cost provider that has this feature set."
"The price is reasonable. It's not exorbitant. CrowdStrike and other players are on the higher side."
"Trend Micro recently switched from a license-based pricing model to a credit system, which caused some initial frustration during my renewal."
"The pricing for Trend Vision One is reasonable."
"The solution is fairly priced."
"Trend Micro's cost is higher than other solutions. That is the main reason why we need to switch to another solution."
"Trend Micro solutions are very expensive compared to other solutions. Even though everything is in one console, each feature requires a separate license."
