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."
"The proactive approach is the best feature."
"Scaling is not a problem at all."
"The scalability is very good, and once again, being based on the cloud makes it very scalable."
"TrendAI Vision One has positively impacted our organization by improving security and reducing the hazard of needing to switch between consoles since it has one single platform embedded with every solution."
"The best part is the XDR threat investigation, which includes different modules like Observer Attack Techniques, Workbench, and Detection Model Manager."
"The best features in TrendAI Vision One are the workbench and the XDR feature for the playbooks; we continue to use these two features extensively."
"The organizational view simplifies management and improves visibility, helping us identify areas for action."
"The most valuable features of Trend Vision One are its capabilities for XDR, EDR, MDR, and NDR, allowing for network detection and response."
 

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."
"There have been a few incidents where intruders could get into the network even while the product was deployed."
"TrendAI Vision One is expensive."
"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."
"TrendAI Vision One could bring in more data loss prevention capabilities specifically on the endpoints, as the current offering lacks some important capabilities."
"They need to modify their licensing mechanism and improve their AI-based detections."
"At the Endpoint Security level, the agents being used in TrendAI Vision One have several problems; we frequently encounter incidents where the agent consumes resources uncontrollably."
"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."
"The experience of first using Trend Vision One is really difficult due to the steep learning curve."
 

Pricing and Cost Advice

Information not available
"The pricing for Trend Vision One is reasonable."
"When I compare it to its peers that can do the same, it is cost-effective."
"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."
"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 would be nice if it was a little bit cheaper, but I think it has a fair price. It is comparable to others in the market."
"Trend Micro's cost is higher than other solutions. That is the main reason why we need to switch to another solution."
"The cost is considered fairly priced."
"Trend Micro XDR is reasonably priced for its value, comparable to other products like VMware Carbon Black."
