Cryptographic Bills of Materials (CBOMs) went from academic concept to compliance requirement in under two years. NIST’s post-quantum standards are finalized, the EU Cyber Resilience Act mandates cryptographic transparency, and enterprises are realizing they can’t migrate what they can’t find.
The CBOM tooling market has responded. From AI-driven platforms backed by $500M+ in funding to open-source projects from the Linux Foundation, organizations now have real options for cryptographic discovery and inventory. This comparison covers the six tools that matter in 2026, when each fits, and how to choose between them.
Why CBOM Tools Matter Now
Three regulatory and technical drivers are forcing action:
- NIST PQC migration deadlines — CNSA 2.0 requires hybrid key exchange by 2027 and full PQC by 2033. You can’t migrate algorithms you haven’t inventoried.
- EU Cyber Resilience Act (CRA) — Requires manufacturers to document cryptographic components in products. CBOM is the mechanism.
- 47-day certificate lifetimes — Shorter lifetimes expose weak automation. Discovery tools identify certificates that lack automated renewal.
The market splits into two categories: discovery-only tools that find and catalog cryptographic assets, and discovery + remediation platforms that can also fix what they find.
Tool Comparison Overview
1. SandboxAQ AQtive Guard
Background: Spun out of Alphabet (Google) in 2022, SandboxAQ has raised over $500M in funding and secured partnerships with the U.S. Department of Defense and multiple NATO allies. Their approach combines AI/ML for cryptographic vulnerability detection with non-human identity (NHI) management.
What it does:
- Network traffic analysis to identify cryptographic protocols in use

Evaluation Checklist
Before selecting a tool, answer these questions:
- What are you scanning? Network traffic, source code, configurations, or all three?
- Do you need remediation? Or just discovery and reporting?
- What’s your compliance driver? CRA, DORA, NIST, or internal policy?
- What format do you need? CycloneDX (standard) or proprietary (vendor-specific)?
- What’s your budget? Free (CBOMkit) to six figures (SandboxAQ)?
- Do you have mainframes? If yes, IBM QSE is likely required regardless of other choices.
- Do you already have CLM? If not, QCecuring CBOM gives you both in one platform.
Combining Tools: The Multi-Layer Approach
Many enterprises use more than one tool:
| Layer | Tool | Purpose |
|---|---|---|
| Code/build time | PQCA CBOMkit | Generate CBOM during CI/CD |
| Runtime/network | SandboxAQ or QCecuring | Discover crypto in production traffic |
| Certificate management | QCecuring CLM | Manage lifecycle of discovered certificates |
| Key management | Fortanix DSM | Manage and inventory encryption keys |
| Compliance reporting | EncryptionConsulting or QCecuring | Map findings to regulatory frameworks |
The combination of CBOMkit (free, CI/CD) + QCecuring CBOM (runtime discovery + remediation) covers most enterprise needs without the six-figure price tag of AQtive Guard.
Market Trajectory
The CBOM market is consolidating around a few patterns:
- Discovery is commoditizing — Network scanning for TLS configurations is table stakes. Differentiation comes from code analysis depth, AI-driven prioritization, and remediation.
- CycloneDX is winning — OWASP’s CycloneDX format is becoming the de facto standard for CBOMs. Tools that output proprietary formats will need to add CycloneDX export.
- Integration beats standalone — Standalone discovery tools create “yet another dashboard.” Tools integrated with CLM, KMS, or SBOM platforms provide more value.
- Open source sets the floor — PQCA CBOMkit establishes what’s freely available. Commercial tools must justify their premium with scale, AI, or remediation.
FAQ
Q: Do I need a CBOM tool if I already have an SBOM tool? A: Yes. SBOMs (Software Bills of Materials) list software components and their versions. CBOMs specifically catalog cryptographic algorithms, key sizes, certificate chains, and protocol configurations. An SBOM tells you that you use OpenSSL 3.2.1. A CBOM tells you that OpenSSL is configured with RSA-2048 keys and TLS 1.2 with specific cipher suites. Some SBOM tools (Syft, Trivy) are adding CBOM extensions, but dedicated CBOM tools provide deeper cryptographic analysis.
Q: Is CycloneDX the only CBOM standard? A: CycloneDX (from OWASP) is the most mature CBOM standard with dedicated cryptographic component types. SPDX (from Linux Foundation) is adding cryptographic extensions but isn’t as far along. For compliance purposes, CycloneDX is the safer choice today. Most tools that output proprietary formats can export to CycloneDX on request.
Q: How often should I regenerate my CBOM? A: Continuously for network-discovered assets (certificates expire, configurations change). For code-level CBOMs, regenerate on every build or at minimum every release. Point-in-time CBOMs are useful for compliance snapshots but miss drift between scans.
Q: Can open-source CBOMkit replace commercial tools? A: For CI/CD pipeline CBOM generation, yes. CBOMkit handles dependency scanning and code-level crypto identification well. For network discovery, runtime monitoring, and automated remediation, you’ll need commercial tools. Many organizations use CBOMkit for build-time and a commercial tool for runtime — they complement rather than compete.
Q: What’s the relationship between SandboxAQ and Google? A: SandboxAQ was incubated within Alphabet (Google’s parent company) and spun out as an independent company in 2022. It retained some Google AI/ML technology and talent but operates independently. The Alphabet connection provides credibility and access to AI research, but SandboxAQ is a separate entity with its own investors and governance.
Q: How do CBOM tools handle encrypted traffic they can’t inspect? A: Network-based tools (SandboxAQ, QCecuring, EncryptionConsulting) analyze TLS handshakes — the cipher suite negotiation happens in plaintext before encryption begins. They can identify algorithms, key sizes, and certificate details without decrypting payload traffic. For internal east-west traffic, some tools integrate with service mesh sidecars (Envoy, Istio) that have access to plaintext configuration.
