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."
"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 thing for us as a customer is that we can spend more time in other places as it's simpler to have that overview. We have much more time for other tasks."
"The most valuable feature of Trend Vision One is response management; when there is a malware issue, we need to isolate the endpoint, which I can do through response management. I"
"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."
"The proactive approach is the best feature."
"It is so helpful to have something that pulls all the data into one visual representation of the events."
"The user interface is very good."
"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."
"Trend Vision One provides centralized visibility and management across protection layers, which is crucial for compliance."
 

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."
"In terms of improving Trend Vision One, it might sound silly, yet it seems notoriously uncooperative with middle clicks and opening sections in new tabs. I'm a big tab browser, and it feels hitting a brick wall when I have to refresh in a new tab or make a copy of a tab to move forward."
"There should be a bit more dynamism when it comes to their playbooks in terms of the action triggers. That is the only thing that I would want to see a bit more."
"The agent system is very slow, it needs to improve its performance."
"Improving the user interface would be helpful—it can be confusing, especially if you do not use it daily."
"However, the area where it should improve is that it gets stuck. It does not have that much amount of data. It does not understand easily, and we have to explain it more."
"It would be great if there were Trend Micro products that could enhance the security of these devices, either as part of our product or in some other way integrated into our offering."
"In future releases of Trend Vision One, I would like to see improvements regarding role-based access control, as it is important to ensure that when granting admin access to a person, their visibility is limited to only their respective markets."
"The only disappointing aspect is that every time new features are adopted, additional credits are required, which could push the budget over. This practice should really be reconsidered by Trend."
 

Pricing and Cost Advice

Information not available
"The pricing is fair and not on the higher side."
"Trend Micro's cost is higher than other solutions. That is the main reason why we need to switch to another solution."
"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."
"Trend Vision One offers a competitive price-to-value ratio."
"From a pricing standpoint, they're a really good negotiator and they'll work with you."
"I feel that Vision One is a bit expensive. As for the pricing or licensing, I would rate it a seven out of ten."
"The pricing of the solution is okay. There is a need for me to look into the new pricing plan introduced by the solution recently."
"When I compare it to its peers that can do the same, it is cost-effective."
