July 21, 2022, Workload Security—Trend Cloud One - Endpoint & Workload Security accounts
created prior to November 23, 2020 may still be allowing their Deep Security Agents
access to Trend Cloud One - Endpoint & Workload Security by using static IP addresses
provided on the Port numbers, URLs, and IP addresses documentation page. Starting on December 31, 2022, the Agent will connect only by
using the fully-qualified domain names (FQDNs) and not by using IP addresses. To avoid
service interruptions, customers filtering outbound traffic from their protected workloads
to the outside internet must ensure they configured their firewall to add allowlist
entries for the URLs listed at Port numbers, URLs, and IP addresses prior to December 31, 2022. If you do not filter outbound traffic or you are already
using FQDNs, there is no action required.
How do I know whether I need to change something in my environment?
If your network is filtering outbound traffic to the internet using any static IP
addresses listed on this page, you must update your firewall's allowlist to use the domain-name URLs instead of
the IPs.
