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."
"TrendAI Vision One allows us to monitor attacks in real time, which is a significant benefit, and enables us to use different products with a flexible license, helping to reduce the time to detect and respond to different threats through rapid responses and predefined playbook templates."
"Trend Vision One's most valuable feature is its endpoint firewall rules."
"We can scale the product as needed."
"By switching to TrendAI Vision One, I have reduced my risk by approximately eighty percent."
"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."
"Trend Vision One is an integrated platform where I can get all the information about all the endpoints, whether it be a server, laptop, or desktop."
"TrendAI Vision One gives us better visibility to detect and respond to threats because we can now see more than ever before."
"It is so helpful to have something that pulls all the data into one visual representation of the events."
 

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 the CPU utilization is so high that the computer crashes or lags behind."
"I would like to have more integration with mobile device management."
"Vision One's search could be improved. While the platform is very user-friendly, the search feature uses terms that aren't as intuitive."
"Vision One generates numerous false positives, forcing unnecessary investigations and highlighting a need for improved filtering options."
"Sometimes it’s difficult to find your way around."
"They could improve the support case experience because whenever we reach out to the support team, in response, they first put what I think are some ready-made templates, and they just put it as a reply."
"The solution lacks compatibility with other products. It needs to integrate better with other surrounding solutions."
"We'd like to see a few more integrations."
 

Pricing and Cost Advice

Information not available
"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."
"When we have a good product such as Trend Vision One, the price is fine."
"The solution is fairly priced."
"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."
"Trend Micro's licensing is outsourced to third-party vendors, resulting in price variations depending on the vendor."
"Trend Vision One is cost-effective because it offers detailed reporting and environment control features."
"Trend Vision One offers a competitive price-to-value ratio."
"When I compare it to its peers that can do the same, it is cost-effective."
