In April 2014, a bug in OpenSSL called Heartbleed exposed private keys and sensitive data across millions of servers worldwide. The hardest part was not fixing it but finding every system that ran the flawed version. Security teams spent days manually tracing their systems. This work would have been completed in minutes by a structured cryptographic inventory. That visibility gap is exactly what CBOM tools are built to close.
A Cryptographic Bill of Materials (CBOM) is a structured list of every cryptographic asset in your systems. It could be algorithms, certificates, keys, protocols or libraries. CBOM tools automate the generation and management of this list. What was once a manual exercise is now a governed, auditable process. This guide walks you through what these CBOM tools list do, what to look for when evaluating them and how regulated companies can use them to meet RBI and CERT-In requirements.
Why demand for CBOM tools has surged
Two forces are driving adoption simultaneously: regulatory pressure and the quantum threat.
Regulatory mandates are now in effect
India’s regulators have moved decisively. The Reserve Bank of India’s Advisory No. 11/2024 (issued November 2024) references CERT-In’s Technical Guidelines on CBOM. It places clear expectations on banking sector entities. CERT-In’s Technical Guidelines Version 2.0 (released July 2025) go even further. It makes CBOM compulsory for critical applications and defines minimum data elements that every cryptographic asset entry must have.
Globally, NIST published its post-quantum cryptography standards in 2024 and recommends completing migration from quantum-vulnerable algorithms by 2030. The EU Cyber Resilience Act mandates cryptographic component documentation for digital products. You cannot demonstrate compliance with any of these frameworks without an accurate CBOM in place.
The quantum threat
Quantum computers capable of breaking RSA and elliptic curve cryptography (ECC) are not yet deployed at scale. But attackers are not waiting. They are capturing encrypted traffic today to decrypt it once capable quantum hardware arrives. Financial records with long retention periods and long-lived signing keys are already at risk. The right tools give your team a precise map of what needs to be replaces, before the deadline forces a rushed migration.
What CBOM tools do
Capable tools deliver across four core functions. Each one matters for regulated enterprises:
- Discovery: Scan source code repositories, container images, network endpoints and HSM/KMS environments to locate every cryptographic asset in use.
- Inventory: Consolidate findings into a structured, CycloneDX-compliant CBOM linked to the applications that own each asset. CycloneDX version 1.6, which incorporates CBOM capability, has been adopted as international standard ECMA-424, the recognised benchmark for cryptographic inventory formats.
- Risk scoring: Flag deprecated algorithms (SHA-1, RSA-1024, 3DES) and quantum-vulnerable systems with risk-based prioritisation instead of flat lists.
- Continuous monitoring: Track changes across your cryptographic estate and alert teams when new vulnerabilities or compliance gaps appear.
Solutions that only perform discovery are a starting point. Regulated enterprises need all four functions to satisfy audit requirements and manage ongoing risk.
5 things to look for in CBOM tools
Evaluate CBOM tools list against the following criteria:
Multi-source scanning
A single scan type creates blind spots. Good CBOM tools combine network scanning, code repository analysis, artifact scanning and HSM/KMS integration to build a complete, de-duplicated picture.
Regulatory mapping
Look for platforms that map findings directly to RBI, CERT-In, NIST and EU CRA frameworks. This cuts audit preparation time and generates regulator-ready evidence packs without manual effort.
Post-quantum readiness tracking
The right tools detect quantum-vulnerable algorithms, track adoption of NIST-approved standards like ML-KEM and ML-DSA and generate migration roadmaps prioritised by quantum risk exposure.
Deployment flexibility
BFSI and regulated sectors often cannot route cryptographic data through third-party cloud environments. On-premise and air-gapped deployment support is non-negotiable for many regulated entities.
Risk-based reporting
A flat CSV of algorithms is not actionable. Look for platforms that prioritise findings by exploitability and business impact – the way a penetration testing report does, not a raw data dump.
Conclusion
Cryptographic visibility is now a governance requirement for regulated organisations. RBI and CERT-In have set clear expectations. NIST has set an official deadline for transitioning away from legacy encryption algorithms. And the threat to long-lived encrypted data is already active today.
The right CBOM tools give your security and compliance teams a continuously updated map of your cryptographic estate. Something that holds up under audit and supports a structured post-quantum migration.
CyberNX’s NXRadar CBOM platform is built for this challenge. It combines multi-source scanning across network, code, artifact and HSM/KMS environments, maps findings to RBI, CERT-In and NIST frameworks and supports on-premise deployment for BFSI and regulated sectors.

CBOM tools FAQs
What is the difference between CBOM tools and SBOM tools?
SBOM tools inventory software components like libraries, packages and dependencies. CBOM tools focus specifically on cryptographic assets: algorithms, keys, certificates and protocols embedded across those components. CBOM extends the SBOM and adds the cryptographic layer that regulators now expect as a separate structured artefact.
Are CBOM tools mandatory under Indian regulations?
CERT-In’s Technical Guidelines Version 2.0 (July 2025) make CBOM mandatory for critical applications. RBI’s Advisory No. 11/2024 references these guidelines directly. Regulated entities should treat CBOM software as a compliance requirement rather than a best practice.
How do CBOM tools support post-quantum migration?
They build the cryptographic inventory that every NIST migration roadmap starts with. They identify quantum-vulnerable algorithms, prioritise applications by risk and track adoption of NIST-approved replacements. Without this inventory, PQC migration planning remains guesswork.
Can open-source CBOM tools meet enterprise compliance needs?
Some open-source options are well-suited to code-level scanning and CI/CD integration. For regulated enterprises requiring multi-source discovery, compliance-mapped reporting, on-premise deployment and continuous monitoring, a commercial platform is typically necessary.
