Cryptographic failures have a knack for turning a quiet weekend into a chaotic, all-hands-on-deck emergency.

The major Certificate Authority (CA) distrust events involving DigiNotar in 2011, Symantec in 2017-18, and Entrust in 2024-25 created similar disruption. In each case, organizations had days, not months, to replace critical certificates across their entire production environments.
