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

"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."
"I'm satisfied with the level of coverage. The policies have been very useful and detailed."
"Trend Vision One offers superior integrations, enhanced tool capabilities, and expanded solutions for network security, firewalls, and remote malware scanning."
"We had a quick deployment. The solution is easy to set up."
"I appreciate the value of real-time activity monitoring."
"TrendAI Vision One offers a complete XDR solution that integrates all of these aspects into a single application so instead of starting my shift and logging on to separate products for all of these, I just need to log in to TrendAI Vision One and I have single-click access to all of these applications."
"We have a business relationship with Trend Micro and I'd advise other organizations to try it out because it's a good, solid product and we have been quite pleased with the overall results."
"This full security posture positions us well for our future security roadmap."
"TrendAI Vision One offers excellent extended detection and response capabilities through EDR and XDR solutions, as it is a complete package for organizational threat protection across email, endpoints, cloud networks, servers, and data centers."
 

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."
"It would be better if it were more user-friendly. It would also be better if the implementation were more straightforward."
"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."
"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."
"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."
"The area for improvement is to provide more clarity on the query part, including examples for creating reference sets and documenting capabilities thoroughly so future users can benefit without needing to experiment."
"One area that requires improvement is the installation process of the agents, as it is not seamless."
"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."
"Trend Vision One has some usability issues."
 

Pricing and Cost Advice

Information not available
"Trend Vision One is an expensive product."
"Trend Micro XDR is expensive."
"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."
"It is definitely not cheap. I do believe you get what you pay for to some degree. It is cost-effective."
"Trend Micro's licensing is outsourced to third-party vendors, resulting in price variations depending on the vendor."
"Trend Micro XDR is reasonably priced for its value, comparable to other products like VMware Carbon Black."
"The pricing is competitive, and the cost aligns with the features we receive."
"From a pricing standpoint, they're a really good negotiator and they'll work with you."
