On Friday, 4/22/2022, from approximately 8:28 a.m. until 1:11 p.m. (ET), some users were unable to log in to their KCM GRC consoles with single sign-on (SSO).
The incident was caused by a backend update that was meant to block an increase of malicious traffic. This update also prevented KCM GRC from successfully validating SSO attempts. Once the issue was identified and corrected, SSO for KCM GRC was able to return to normal performance by 1:11 p.m. (ET).
To prevent this issue in the future, we are adding improvements to our processes for monitoring the console and validating changes.
No data loss occurred as a result of this issue.
