On Thursday, March 5, 2026, from approximately 02:20 until 03:10 \(UTC\), some customers experienced expired SSL certificate warnings when accessing their Defend and Prevent admin consoles. This incident was caused by an expired certificate for an internal service. To resolve this issue, we deployed a new certificate and updated all affected instances. The Defend and Prevent consoles returned to normal performance by 03:10 \(UTC\). To prevent this type of issue in the future, we are improving our certificate monitoring. No data loss occurred as a result of this issue.
