It’s Monday morning, and a global bank’s customers can’t log into their accounts. Trading desks are stalled, wire transfers are frozen, and call centers are overwhelmed. The culprit isn’t ransomware, a DDoS attack, or even insider sabotage. It’s a single expired certificate embedded in a third-party software library.

What if that same faulty certificate isn’t unique to one bank, and is embedded in a widely used third-party software package adopted by dozens of other financial institutions? Within hours, outages ripple across markets. Regulators are on the phone, the press is circling, and the board is demanding answers.

This isn’t just a hypothetical scenario. It’s exactly what happened to Alaska Airlines last year. What looked like a minor oversight was, in fact, a breakdown in certificate lifecycle governance with widespread operational impact.

The takeaway is clear: the digital certificate supply chain is a systemic resiliency issue. Yet, too often, certificate lifecycle management (CLM) is still treated as a low-level IT task. In reality, it belongs squarely on the board’s agenda.
