While most cybersecurity conversations in India's financial sector focus on Software Bill of Materials (SBOM), a newer and arguably more critical compliance requirement is emerging: the Cryptography Bill of Materials (CBOM). If SBOM tells regulators what open-source components you're running, CBOM tells them how you're protecting data — and whether your cryptographic posture will survive the next decade.
O3 Security is the pioneer in CBOM for financial institutions, helping Indian banks, NBFCs, AMCs, and brokers meet the cryptographic governance expectations embedded in SEBI CSCRF and RBI cybersecurity frameworks.
What is a Cryptography Bill of Materials (CBOM)?
A CBOM is a structured inventory of all cryptographic assets within your technology environment — every algorithm, key, certificate, cryptographic library, and protocol in use across applications, infrastructure, APIs, and databases. Just as an SBOM inventories software components, a CBOM inventories your cryptographic building blocks.
CBOM captures: Symmetric algorithms (AES-128 vs AES-256), asymmetric algorithms (RSA-2048, RSA-4096, ECC), hash functions (MD5, SHA-1, SHA-256, SHA-3), TLS versions and cipher suites, certificate authorities and expiry dates, cryptographic library versions (OpenSSL, BouncyCastle), key management practices, and quantum-vulnerable vs quantum-safe algorithms.
Why SEBI and RBI Are Focused on Cryptographic Governance
SEBI CSCRF explicitly requires that Regulated Entities implement cryptography controls aligned with current standards and maintain visibility into their cryptographic posture. Three driving forces make CBOM urgent for Indian financial institutions today:
1. Quantum Computing Threat to Current Cryptography
RSA, ECC, and Diffie-Hellman — the algorithms protecting virtually every financial transaction today — are mathematically vulnerable to quantum computers running Shor's Algorithm. Nation-state adversaries are already harvesting encrypted data today under a "store now, decrypt later" strategy. NIST finalised its first post-quantum cryptography standards in 2024. Financial institutions that don't know which systems rely on quantum-vulnerable algorithms cannot plan their migration.
2. Cryptographic Debt in Legacy Financial Systems
India's financial infrastructure runs on applications ranging from modern cloud-native microservices to core banking systems from the 1990s. These legacy systems frequently use deprecated algorithms — MD5, SHA-1, DES, 3DES, TLS 1.0/1.1, RSA-1024 — that are no longer considered cryptographically secure. Without a CBOM, these vulnerabilities are invisible.
3. Certificate Sprawl and Outage Risk
The average large financial institution has thousands of SSL/TLS certificates across its infrastructure. Certificate expiry outages are increasingly common — and in the financial sector, they translate directly to service unavailability, regulatory breaches, and reputational damage. A CBOM provides complete certificate lifecycle visibility.

How O3 Security Automates CBOM for Indian Financial Institutions
O3 Security's platform performs agentless discovery of cryptographic assets across cloud environments (AWS, Azure, GCP), on-premise infrastructure, application code, containers, and APIs — building a complete, continuously updated CBOM without manual inventory work.
Post-Quantum Readiness Assessment
O3 Security maps every RSA, ECC, and DH implementation to NIST's post-quantum migration priority guidance, showing which systems need immediate attention vs. which can be addressed in the next 2–3 years. The platform generates a migration roadmap aligned with SEBI CSCRF timelines.
SEBI Compliance Reporting
O3 Security maps cryptographic findings directly to SEBI CSCRF control requirements, generating audit-ready evidence packages. When a SEBI inspector asks for evidence of cryptographic control implementation, the O3 Security report is your answer.

SBOM tells you what is running in your software. CBOM tells you how that software is protecting data. They are complementary, not competing. A comprehensive software security posture requires both: SBOM for supply chain vulnerability management (Mend.io) and CBOM for cryptographic governance (O3 Security). SEBI CSCRF's holistic approach to cyber resilience implicitly requires both capabilities.
The Timeline: When Does Cryptographic Governance Become Mandatory?
SEBI CSCRF's Phase 1 requirements are already in effect for top-tier REs. CERT-In's cryptographic guidelines strengthen each year. The NIST post-quantum standards are finalised. The question for Indian financial institutions is not whether cryptographic governance will be required — it's whether you'll build that capability proactively or scramble to comply after an enforcement action.
Organisations that start their CBOM programme now will have clean data for migration planning, time to implement quantum-safe alternatives methodically, and a compliance evidence trail that demonstrates proactive governance. Those that wait will face compressed timelines, higher remediation costs, and potential regulatory exposure. O3 Security gives you the visibility to act now.
