Article 14 reporting through ENISA Single Reporting Platform is active law today across all 27 EU member states.
The 24h clock starts the instant active exploitation in the wild is confirmed, NOT when a root cause or fix is authored.
The ENISA SRP automatically encrypts and broadcasts alerts to the national CSIRTs of all impacted member states.
Concealing active exploits or missing deadlines risks fines up to €15,000,000 or 2.5% of annual worldwide revenue.
