Typically, upgrades and routine maintenance tasks are performed without any service
impact.
Periodically, a maintenance window affecting the service is required. This window
allows Trend Micro to perform specific planned maintenance tasks. Trend Micro provides
at least 7 days notice prior to any scheduled maintenance.
To be notified of scheduled maintenance, subscribe to the Trend Cloud One maintenance
RSS feed
.

If you have any questions, contact Trend Micro support.
Scheduled general maintenance
System maintenance for Trend Cloud One is scheduled for all regions between 03:00
and 10:00 UTC on Saturday, July 26, 2025.
During this period, the following services will be unavailable:
- Trend Cloud One - Endpoint & Workload Security agent connections.
- Administration and API access to the Trend Cloud One - Endpoint & Workload Security console.

quickly as possible.
Maintenance window details are made public through this page at least 7 days before
a maintenance window, as required by the Trend Micro SLA.
