RBI, SEBI, and IRDAI Cybersecurity Guidelines Explained for IT Leaders

Financial services technology teams in India sit at a rare intersection: customer trust, systemic risk, and relentless threat activity. When regulators issue cybersecurity guidance, it is not only about “security best practice”. It is about operational resilience, market stability, and clear accountability.

For IT leaders, the toughest part is not reading a circular. It is converting overlapping expectations from RBI, SEBI, and IRDAI into a single operating model that stands up to audits, incident scrutiny, and board reviews, while still shipping products and keeping platforms running.

This note breaks down what each regulator is asking for, where the overlaps lie, and how to translate the requirements into a practical, evidence-driven programme.

Why RBI, SEBI, and IRDAI feel different in implementation

RBI’s approach tends to read like enterprise IT governance: board oversight, control assurance, risk management, and repeatable processes across banks, NBFCs, and allied financial institutions. The 2023 Master Direction is especially significant because it consolidates earlier instructions into a single structure and sets clearer expectations for April 2024 onwards.

SEBI’s lens is market integrity and cyber resilience. For market infrastructure institutions (MIIs), the focus is deep control testing, continuous monitoring, and high audit frequency. For the wider set of SEBI-regulated entities, the 2024 Cybersecurity and Cyber Resilience Framework (CSCRF) pushes structured implementation, SOC expectations, and defined compliance timelines based on entity category.

IRDAI’s guidelines, updated in 2023, apply broadly across insurers and insurance intermediaries. The tone is governance plus control coverage, with explicit references to global frameworks (the NIST CSF mapping is a useful cue for structuring your programme).

A compact map of the key documents and what they signal

The table below is a simplified working view for IT leadership discussions. Teams should still read the original circulars and directions for exact wording, formats, and reporting timelines.

RBI: what the 2023 Master Direction changes for day-to-day execution

Many organisations already ran RBI-aligned controls using a patchwork of circulars, internal policies, and audit checklists. The Master Direction (issued Nov 2023, effective Apr 2024) changes the conversation inside IT leadership meetings because it offers a single consolidated spine for governance, risk, controls, and assurance.

Expectations that typically drive engineering and operations plans include policy discipline, board-level reporting, periodic control testing, resilience metrics (RPO and RTO), and auditability.

A practical interpretation for IT leaders is: RBI wants security controls to be managed as a system, not a set of tools. You can have strong EDR and SIEM, but if review cadences, exception handling, vendor risk processes, and evidence trails are weak, you are exposed during assurance.

RBI’s earlier 2016 framework for banks is still useful as a “why” document. It clearly pushed board-approved cyber security policy, defined security roles, structured incident response, mandatory incident reporting, and continuous surveillance using SOC capabilities.

SEBI: resilience and audit readiness at market speed

SEBI’s cybersecurity expectations often feel operationally intense because market entities run high-availability platforms and are exposed to time-sensitive risk. MIIs have explicit requirements like two cyber audits per financial year, along with CEO/MD certification on key coverage areas, and closure tracking for findings in protected systems.

For the wider ecosystem, the 2024 CSCRF matters because it pushes uniformity across a diverse set of regulated entities, with implementation timelines that scale based on size and system impact. It also recognises that not every entity can build a large in-house SOC, so it allows for models where SOC capability is obtained through managed setups or market-provided options, provided monitoring and response duties are clearly met.

SEBI’s direction is clear in spirit: detect earlier, respond faster, test more regularly, and prove it with repeatable evidence.

IRDAI: one set of cyber rules across insurers and intermediaries

IRDAI’s 2023 Information and Cyber Security Guidelines consolidated earlier insurer and intermediary guidance into a single, broader set. For IT leaders, this reduces ambiguity across group companies and distribution partners, but it raises the bar for intermediaries that previously treated cyber controls as “lighter” requirements.

The guidelines call for strong governance, documented roles (including security leadership), periodic risk assessment, secure development practices, encryption and access controls, incident response and crisis planning, and external audits by a suitably certified firm.

A useful implementation shortcut is IRDAI’s explicit reference to global standards, including a mapping to the NIST Cybersecurity Framework in the annexure. If your organisation already runs ISO 27001-aligned controls, you can map those controls to IRDAI’s themes and then fill the regulator-specific reporting and audit evidence requirements.

The overlaps that help you build one control baseline

Most BFSI groups end up supporting more than one regulator across subsidiaries, product lines, or distribution models. Instead of building three parallel programmes, treat RBI-SEBI-IRDAI guidance as different emphases on a shared baseline.

Across all three, the strongest repeating themes are governance, continuous monitoring, testing, incident response, third-party risk management, and proof of control operation.

A workable baseline can be framed like this, and then extended per regulator:

• Governance and accountability: board visibility, defined security leadership roles, policy approval and periodic review
• Risk and control lifecycle: periodic risk assessment, control design, control operation, control testing, remediation tracking
• Monitoring and response: SOC capability, log management, alert triage, incident handling, post-incident corrective actions
• Assurance: internal audits, external audits, evidence retention, certification and management attestations
• Supply chain: vendor onboarding controls, access governance for third parties, contractual security clauses, periodic reviews

Converting regulatory text into a programme your teams can run

The fastest way to lose momentum is to treat compliance as a document-only project owned by a small risk team. Regulators are pointing to operating discipline, so engineering, infrastructure, and security operations need a shared implementation backlog.

Start with a “control map” that links each regulatory clause to: the system scope, the control owner, the tool or process used, the evidence produced, and the review frequency. This keeps audits from becoming a frantic evidence hunt.

After you have that map, execution tends to fall into a predictable set of workstreams.

• Build a single control library: one internal standard mapped to RBI, SEBI, IRDAI clauses
• Set review cadences: quarterly risk reviews, monthly vulnerability closure reviews, scheduled DR drills
• Define SOC operating metrics: alert SLAs, incident severity model, escalation paths, mean time to detect and respond
• Make compliance testable: automated configuration checks where possible, repeatable manual checklists where needed
• Treat remediation like product work: prioritised backlog, owners, due dates, verification, closure evidence

What audits and regulators usually ask you to “show”, not just “say”

Audit success is rarely about a perfect architecture diagram. It is about whether you can prove that controls are operating, exceptions are handled, and risks are owned.

You can reduce audit friction by creating an evidence pack that is refreshed through the year, not assembled at the last minute. Keep it aligned to your control map.

Common evidence artefacts include:

• Policies and board approvals

• Asset inventory and data classification records

• Vulnerability scan summaries and closure proof

• Patch compliance reports

• SOC runbooks and shift rosters (where applicable)

• Incident records, root cause analysis, corrective action tracking

• BCP and DR test results with RPO and RTO outcomes

• Third-party risk assessments and access review logs

• Logs and SIEM alert samples

• Firewall and endpoint policy exports

• Secure SDLC checklists

• User access review sign-offs

• Backup restoration test screenshots

Incident reporting and coordination: plan for “who reports what” early

RBI’s bank framework explicitly calls for reporting cyber incidents, including attempted incidents, in prescribed ways. SEBI’s frameworks similarly expect structured incident handling and reporting formats. IRDAI expects reporting of breaches to IRDAI and also recognises the role of CERT-In reporting where applicable.

This is less about a single form and more about orchestration: security operations, legal, risk, business owners, and communications teams need a shared playbook. Your playbook should define trigger thresholds, severity criteria, timelines for internal escalation, external reporting routes, and evidence preservation steps for forensics.

One simple improvement many teams make is to run at least two tabletop exercises each year: one focused on ransomware with service disruption, another on data leakage through third-party access. The output becomes audit-ready evidence and makes real incidents less chaotic.

Using standards to simplify multi-regulator compliance

IRDAI’s NIST CSF mapping is a helpful hint: regulators are comfortable when firms anchor their programmes in recognised frameworks and then layer India-specific regulatory requirements on top. Many BFSI institutions also use ISO 27001 as the management system layer, then maintain regulator-specific control extensions and reporting templates.

This approach helps because:

1. Standards give consistent language for risk, controls, exceptions, and continuous improvement.
2. Tooling can be configured once for the baseline and reused across entities.
3. Training and awareness become easier to standardise across large organisations.

Where an implementation partner can add real value

Even mature security teams run into capacity constraints, especially when timelines are tight (as with SEBI CSCRF timelines) or when legacy systems complicate monitoring and patching.

An IT services partner can help with control mapping, security architecture, engineering hardening, cloud security configuration, SOC build-out, and audit readiness documentation, provided ownership stays inside the regulated entity.

Atrity Info Solutions Private Limited operates as an ISO 9001 and ISO 27001 certified Indian IT services company and works across software development, cloud solutions, cybersecurity, and consulting. For regulated organisations, such capabilities are typically useful in three areas: building secure-by-design applications, strengthening infrastructure and cloud controls, and setting up repeatable assurance artefacts that auditors can verify.

The best outcomes come when partners are brought in with clear boundaries: measurable security outcomes, defined evidence deliverables, and a handover plan that leaves your internal teams stronger and faster.
