Centralized console enables efficient incident management and threat intelligence integration
I am struggling to export all alerts, such as those from the past five to six months, at once. I would like to extract these alerts in Excel format in one go, but I have not found this feature yet. I raised a ticket to the OEM, but I have not received a solution.

AI-driven SOC triage has transformed threat monitoring and keeps our security work focused
The best features UnderDefense offers include mostly triage in-context signals read together across my stack, where one finding replaces many separate checks. A good thing too is its false positive suppression, as I do not get false notifications. Normal activity such as traffic spikes during customer events is recognized and documented, and only the unusual cases reach me. It has full-time support 24/7 with proactive reports, and monitoring runs around the clock. Reports and alerts come to me without even noticing or asking, so it is very useful. My team sees what happened without having to chase it. I find the proactive reporting and 24/7 support to have definitely made a real difference. Proactive reports mean I hear about what happened without having to ask, so I know the state of things at the start of the day, and 24/7 support matters most for traffic spikes and other events outside busy working hours, as I get an answer when I need one without keeping someone on call just in case, saving me a lot of time. Together, they let my team stay on infrastructure work and step in only when a decision is needed. Regarding UnderDefense's AI capabilities, I think the governance and security is the best there is, as the decisions that matter stay with my team and each finding is documented, allowing me to review afterwards how a conclusion was reached. That control and traceability is what I need from AI in a security role. The accuracy and reliability of UnderDefense's AI output is accurate and steady, as findings have matched what I saw when I checked them, and the pattern assessments are consistent, especially during large traffic events or spikes, which is when I depend on them most. When a case needs judgment, the reasoning is there so I can confirm it myself.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The initial setup is very straightforward. CIOs appreciate the ease of installation, server configuration, and the user-friendly dashboard."
"Trend Micro Managed XDR has indeed enhanced our customers' threat detection capabilities. Many of our clients are utilizing it and have experienced positive outcomes. Overall, I would recommend it, especially considering the rising popularity of Trend Micro and its excellent product support."
"The most valuable feature of Trend Micro Managed XDR is the console."
"The tool has significantly improved threat detection and response times for my clients' organizations. The solution has performed exceptionally well, and my customers are pleased with both the performance of the system and the support they receive."
"I appreciate the detection and response methodology used against virus and ransomware attacks."
"Trend Micro Managed XDR can be used to manage all the layers, such as server, access, cloud servers, and email layer, and it is used for overall endpoint security."
"The features are such that MDR is a part of XDR, which includes different products."
"The most valuable feature of Trend Micro Managed XDR is that it protects all of the layers."
"Routine signals are handled and documented, and only cases that need a human decision reach my team, allowing engineers to spend their time on infrastructure hardening instead of log digging."
"UnderDefense groups it into one alert with the caller, the endpoint, and the usual pattern, which allows us to contact the customer the same day with facts in hand."
"The linking, the filtering, and the readable reasoning each help on their own, but together, they allow a small security team to handle the volume our platform produces without losing sight of the cases that matter."
"UnderDefense Gen AI SOC flags behavior that breaks from an account's own baseline, lays out which signals triggered the alert and why it reads as different from normal activity, and helps our team decide within the same day whether we are seeing a legitimate big campaign push or a compromised login."
"Every morning we look at a short list of cases that matter instead of a long list of raw alerts, and each case comes with the full picture, so we can decide in a few minutes whether it needs action."
 

Cons

"The product could benefit from some improvements in its interface and organization. Functionality-wise, it performs well, but there's room for enhancement in terms of user-friendliness. There are ample resources like documents and videos provided by most vendors to assist users, although reaching out for direct support might not always be straightforward."
"Being cost-effective is crucial, allowing customers with lower budgets to access the services. Offering a range of services at various price points ensures that customers can find suitable options without being compelled to explore alternative products or vendors."
"On the financial side, it is quite expensive. If they could reduce the prices, it could attract more customers who are currently deterred by the cost."
"The main drawback is the lack of local language support in Oman."
"I am struggling to export all alerts, such as those from the past five to six months, at once. I would like to extract these alerts in Excel format in one go, but I have not found this feature yet."
"On the financial side, it is quite expensive."
"Trend Micro Managed XDR could improve its support documents. This would allow us to explore the solution better and provide a better presentation to our customers. Addiontaally, there could be more automation features."
"There is a need for greater integration of non-Microsoft devices."
"UnderDefense could improve in onboarding, which takes some dedicated time because the baseline for our high volume upload events needs to be set up first."
 

Pricing and Cost Advice

"The solution's pricing falls within a reasonable range—it's not the most expensive option out there, nor the cheapest."
"The solution is cost-effective."
"There is a subscription needed to use Trend Micro Managed XDR. We are on an annual license."
"Trend Micro's solutions are considerably more expensive than competitors."
"I rate the tool's pricing a six out of ten."
