CERT-In, India’s national cybersecurity authority, has mandated that organizations patch critical vulnerabilities in internet-facing systems within 12 hours of public disclosure. This directive reflects regulatory response to accelerated exploitation timelines. Traditional 30/60/90-day patch cycles are no longer acceptable for internet-exposed assets under this mandate, and the regulatory pressure reflects a global trend toward mandatory accelerated remediation timelines. Organizations with internet-facing infrastructure, particularly those operating in India or under CERT-In jurisdiction, face compliance exposure and elevated operational risk if existing patch processes are not restructured immediately.
