India’s cybersecurity landscape has shifted dramatically. With data breaches and ransomware attacks making daily headlines, regulatory bodies are no longer passive observers—they’re active enforcers.

At the forefront is the Indian Computer Emergency Response Team (CERT-In), the national cybersecurity agency under MeitY. Since its revised directive in April 2022, CERT-In has introduced mandatory guidelines that impact enterprises, cloud providers, data centers, and digital platforms alike.

From incident reporting to log retention and time synchronization, these rules are reshaping how businesses operate in the digital space.
If you’re still treating compliance as a checklist, you’re already behind.

For enterprises, cloud providers, government bodies, and critical infrastructure operators, this isn’t just a policy update—it’s a wake-up call.

❝Cybersecurity in India is no longer reactive. It’s proactive. It’s enforceable. And now, it’s deeply auditable.❞

What Is CERT-In and Why It Matters

The Indian Computer Emergency Response Team (CERT-In) is the national nodal agency under the Ministry of Electronics and Information Technology (MeitY), responsible for safeguarding India’s cyberspace.

Established in 2004, CERT-In’s mission has evolved from merely issuing advisories to now enforcing cybersecurity readiness, resilience, and regulatory compliance across sectors.

Here’s why CERT-In matters:

• Incident Coordination: CERT-In leads India’s response to major cyber incidents like ransomware attacks, data breaches, and critical infrastructure disruptions.
• National Cyber Readiness: It sets mandatory guidelines that organizations must follow to ensure minimum cybersecurity hygiene—such as 6-hour breach reporting, log retention in India, and NTP synchronization.
• Threat Intelligence Hub: It analyzes emerging vulnerabilities and threat actors, issuing timely alerts and patches to reduce attack surfaces.
• Policy & Enforcement Power: Through directives like the 2022 and 2025 guidelines, CERT-In moves beyond advisory roles to a more compliance-driven approach backed by legal and operational consequences.

What’s New in CERT-In Guidelines 2025?

The new CERT-In directive goes deeper than previous iterations, demanding more accountability, clarity, and technical maturity from both auditors and organizations under audit. Here’s what’s changed:

• Defined Roles for Auditors & Auditees
  No more grey areas. Roles, responsibilities, and audit deliverables are clearly structured.

• Mandatory CVSS + EPSS Scoring for Vulnerabilities
  Security findings must include both traditional CVSS and emerging EPSS risk ratings for better risk prioritization.

• Red Teaming & ICS/OT Security Testing
  Organizations handling critical infrastructure must undergo red team simulations and ICS/OT-specific security audits.

• SBOM (Software Bill of Materials) Review
  You must maintain and audit your software components—open-source, third-party, or proprietary—as part of the compliance effort.

• Audit Independence, Ethics & Data Handling Redefined
  Post-audit data storage, access logs, and auditor ethics now have stricter governance.

• Minimum Annual Audit Requirement
  Risk-based audit triggers are encouraged, but one security audit per year is the new minimum standard.

• Secure Coding & Infra Accountability
  Organizations are now accountable for secure SDLC practices, infra hardening, and internal monitoring systems.

Still Struggling with CERT-In’s 2022 Mandates?

If you haven’t fully implemented the April 2022 CERT-In mandates yet—such as the 6-hour breach reporting rule, 180-day log retention in India, NTP sync, or PoC nomination—you’re at risk.

The 2025 guidelines build on those foundations. Non-compliance now has stronger consequences, including legal action, revocation of services, and public reporting.
