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…

The CREM feature is an absolutely essential feature that helps us meet security requirements
Since we started using Trend Vision One, we've been able to enhance our security posture significantly. Trend Vision One has improved significantly over time in providing centralized visibility and control. It started as a set of individual products, but now it feels like one integrated solution. This reduces the need for interfaces or multiple analysis tools. That's why we pursued the one-platform strategy. Trend Vision One has definitely helped consolidate our use of security vendors. We previously used standalone products for endpoint and email protection that weren't integrated. Now, we get the benefits of an integrated solution. I'd estimate we're 50–70% better in security now than we were two years ago. The Cyber Risk Exposure Management (CREM)feature is absolutely essential. Even though we're not critical infrastructure, the NIS2 directive gives us security guidelines. CREM helps us meet these requirements. It is very important to our organization that Trend Vision One integrates AI into the platform. Pattern recognition in forensic data is no longer manageable by humans due to the volume of events. Machine learning is essential to process these and filter what needs human attention. Trend Vision One has improved our organization significantly. Security tasks used to be manual. Now, technology prevents issues or supports staff in detecting them. This shift from manual to technical solutions greatly increased our security. Trend Vision One has reduced the time we spend detecting and responding to threats. I'd say we're 80% faster than before. The platform gives us consolidated data upfront, so we don't have to search for event clues manually. Trend Vision One has helped reduce false alarms. I'd estimate a 50–60% time saving. We have more alerts now than years ago, but also better systems to handle them, making the whole process more efficient. Trend Vision One has helped reduce our cyber risk overall. We now know where gaps are before they become problems, whereas in the past we had to guess. That's a massive improvement. When it comes to operations, the CREM solution helps us identify vulnerabilities in systems. If we patch them, they disappear from the reports—this gives us actionable insights, which is incredibly helpful. It took about half a year to realize the benefits of Trend Vision One after implementation.

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."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"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."
"I can prevent my environment from different types of attacks based on what I see in the Vision One console."
"While it's not an actual feature of the application, I appreciate the clinics and seminars that Trend provides, as I went to one last year that got me from zero to beginner, and I hope to advance to intermediate with another seminar series this year."
"We've found the pricing to be reasonable."
"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."
"Trend Micro can integrate third-party tools, such as Fortinet, Cisco, or any other vendor's firewall, to get the logs and alerts from them. Vision One is much more capable in that way."
"We are very impressed with the single pane of glass visibility that Trend Micro XDR provides."
"The automatic EDR system that notifies us when something is wrong is valuable."
 

Cons

"With Microsoft, support is always crazy, it's not easy to get support."
"Further integration across different Microsoft products would be an improvement."
"The integration is not as seamless compared to competitors like Palo Alto."
"The information captured by Trend Vision One needs to be more detailed."
"Improving the user interface would be helpful—it can be confusing, especially if you do not use it daily."
"The solution lacks compatibility with other products. It needs to integrate better with other surrounding solutions."
"Having more variables within the playbook would be useful. It would allow us to have more refined playbooks for the business. It would allow us to take stronger action through a playbook. It will give us confidence to target a particular area of business where our risk tolerance might be higher or lower. We would like to have more granular playbooks."
"There are limitations in terms of threat response actions."
"The SOAR features (Security Playbooks) are quite limited."
"Vulnerability scanning could be improved. They need to see more CVEs and scan products for known vulnerabilities, allowing for better display and review of potentially exploitable servers by hackers or through configuration settings."
"Vision One could improve its area networking and email security."
