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."
"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."
"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 provides centralized visibility and management across protection layers, which is crucial for compliance."
"One of the best decisions we made was choosing Trend Vision One; it has transformed our entire security and cybersecurity landscape, providing a one-stop solution to manage everything efficiently and effectively."
"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."
"The comprehensive overview of the security status is the most valuable feature of TrendAI Vision One, and its ability to provide centralized visibility and management is quite good because all the relevant data are present, providing everything needed."
"With Trend Vision One, my favorite feature is the app they provide; it simplifies things and clarifies what's going on inside your environment, with a click of a button, you can see what's happening and mitigate very fast."
"The SOC team is the most valuable feature for us because having experts who monitor global threat landscapes and can respond accordingly is incredibly helpful."
"What I like the most about Trend Micro XDR is that the detection and response domain extends to the network. It goes beyond the endpoint and includes data about the network which lets you pinpoint patient zero as well as the root cause of the attack."
 

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."
"Sometimes it’s difficult to find your way around."
"In Trend Vision One, there is always room for improvement. The console is well done, but there might be a bit of improvement needed with the app's capabilities."
"The solution lacks compatibility with other products. It needs to integrate better with other surrounding solutions."
"While blocking an IP address restricts access for 30 days, it eventually becomes accessible again."
"Email security sometimes may lead to some true positive attachments."
"I believe that the interface could be more user-friendly. At times, it is challenging to locate certain features, and they need to reorganize the user interfaces."
"Compared to CrowdStrike sensor, TrendAI Vision One consumes more compute power."
"Vision One's functional capabilities are excellent, but the platform can be upgraded and simplified in many ways. We use multiple playbooks to automate many things, but I'm not sure there are mature cybersecurity applications. There are several external alerts, and their behavior changes daily, so I'm not sure automation can help you that much. We're using the playbooks, but it might require some improvement."
 

Pricing and Cost Advice

Information not available
"I feel that Vision One is a bit expensive. As for the pricing or licensing, I would rate it a seven out of ten."
"They've introduced a credit system, where we purchase credits and then allocate them to the specific services we need active."
"Trend Micro XDR is expensive."
"Trend Micro solutions are very expensive compared to other solutions. Even though everything is in one console, each feature requires a separate license."
"It is costly. It is not that affordable for a small organization. Only big organizations can afford it. It is a new feature that has been added, so its price is fair. Its licensing is probably subscription-based. It is for one or two years."
"I find it to be a cost-efficient platform."
"Trend Vision One offers a competitive price-to-value ratio."
"Trend Vision One is cost-effective because it offers detailed reporting and environment control features."
