What this episode examines
At 2:00 AM, your PSIRT receives a critical alert: an open-source component used across several products may be under active exploitation.
The 24-hour clock may already be running. But your team still does not know which products are affected, whether the vulnerable code path is reachable, what suppliers can confirm, or who has the authority to trigger a regulatory notification.
From 11 September 2026, the Cyber Resilience Act requires manufacturers to submit an early warning within 24 hours and a full notification within 72 hours for actively exploited vulnerabilities and severe security incidents.
This episode examines the operational reality behind those deadlines. We explore why an SBOM can identify the presence of a component but cannot, by itself, determine exploitability. We also look at the role of VEX, product and version traceability, supplier response commitments, technical attack-path validation, decision logs and predefined escalation criteria.
The central challenge is not completing a reporting form. It is coordinating PSIRT, product engineering, suppliers, legal and compliance teams, and customer operations quickly enough to make a decision that remains technically and legally defensible.
The key lesson is clear: CRA readiness means being able to make and evidence a high-consequence decision while the available information is still incomplete.
