20 January 2021 - Rules + General Release Notice

Custom Policy Updates

There is no change to the custom policy as a result of the new Trend Micro Cloud One™ – Conformity release and hence no user action is required. The current custom policy version is 1.23.

New API Documentation Portal

Conformity's API documentation is now available at and is no longer maintained in the old address:

Input Validation for the title in Report form

Validates report title for a valid filename when generating a report and when saving a report config. This is to fix issues where the report can't be opened in certain browsers or operating systems and to prevent security exploits.

General Bug Fixes

  1. Fixed a bug when creating account groups where the account tag entered had to be followed by a comma or enter to save the tag selection.
  2. Fixed a bug where custom user's account permissions for SSO were retained when the user has been revoked.
  3. Fixed a bug to remove default active checkboxes in slack/ms-team communication configuration, but allow users to open and close the configuration then turn automatic notifications on.
