To help these organizations build a strong foundational security posture, the Indian Computer Emergency Response Team (CERT-In) has released CIGU-2025-0003, outlining a baseline of Cyber Defense Controls, which prescribes 15 Elemental Cyber Security Controls—a pragmatic, baseline set of safeguards designed to uplift the nation’s cyber hygiene.
But many MSMEs still ask:
- What exactly are these controls?
- How do they compare with global frameworks like ISO 27001 and NIST CSF 2.0?
- Do we need all three?
This blog attempts to provide clarity and strategic insight.
1. Why CERT‑In’s Elemental Controls Matter for MSMEs
CERT-In's 15 Elemental Cyber Defense Controls provide a foundational security framework for Indian MSMEs, designed to combat rising cyber threats. These controls, mapped to 45 recommendations, enable essential digital hygiene, protect against ransomware, ensure regulatory compliance, and are required for annual audits.
CERT‑In’s Elemental Controls are designed as minimum essential practices that every Indian organization—regardless of size—should implement. Key reasons why these controls matter for MSMEs:
- Mandatory Compliance & Liability: These guidelines will enable the MSMEs to meet the annual audit requirements and the critical incident reporting requirements.
- Protection Against Common Threats: They address critical vulnerabilities such as weak passwords, unpatched software, and lack of backups, covering areas like email security, network protection, and data backup.
- Reduced Financial & Operational Risk: Implementing these controls helps prevent data breaches that cause significant financial losses and operational disruptions, protecting brand reputation.
- Supply Chain Integration: As MSMEs are increasingly targeted, these controls enhance security, making them reliable partners in larger corporate supply chains.
- Structured Security Roadmap: The 15 controls (supported by 45 recommendations) offer a practical, "beginner-friendly" starting point for building a robust, long-term security posture.
Besides, they are:
- Practical
- Technology‑agnostic
- Cost‑effective
- Focused on preventing the most common cyber incidents
For MSMEs that lack dedicated security teams, these controls offer a clear starting point without the complexity of global standards.
2. The 15 CERT-In Elemental Controls vs. ISO 27001
The CERT-In guidelines offer a simplified, actionable starting point for MSMEs to benchmark their security. These controls are intentionally prescriptive, unlike ISO or NIST, which are more framework‑oriented.
