Most enterprises holding digital assets — treasury reserves, tokenised securities, staking positions, or private keys controlling on-chain infrastructure — are operating without a systematic review of how those assets are protected. A crypto security audit closes that gap. Here is what one covers, how it works, and the trigger events that mean you cannot put it off.
In 2026, a hardware wallet security audit is not optional for regulated entities. The SEC's cyber resilience rules and the EU's NIS2 and DORA frameworks require documented, tested custody controls. "We use a Ledger" is not a compliance answer. An audit produces the documented evidence you need.
A well-structured enterprise crypto security audit in 2026 covers six domains. Below is what each domain includes and why it matters.
Which devices hold private keys? Are they the right devices for the asset value and threat model? Are they properly initialised with passphrases and firmware up to date?
Are transactions verified on a trusted screen before signing? What is the organisation's exposure to blind signing attacks? Are multi-sig policies enforced?
How is cold storage segregated from hot wallets? Is there cryptographic proof of integrity? Does the architecture meet air-gap or near-air-gap requirements?
Can the organisation prove it can restore from cold storage within mandated timeframes? Is Time to Clean Restore documented and tested? Are recovery procedures ransomware-resistant?
Are any long-term cryptographic assets protected by algorithms vulnerable to quantum decryption? Does the signing infrastructure support NIST FIPS 203/204/205 migration paths?
Does the custody architecture produce the evidence required by SEC cyber resilience rules, NIS2 Article 21, or DORA ICT risk management requirements?
A CryoVault crypto security audit follows a structured four-step process designed to produce actionable output — not a generic report.
We start by mapping every private key in scope: which wallets hold them, how they were generated, where the backup exists, and who has access. This includes hot wallets, hardware wallets, multi-sig setups, and any on-chain infrastructure (validators, staking pools, smart contract deployer keys).
Not every organisation faces the same threats. A fintech holding $50M in treasury ETH faces different risks than a law firm managing client tokenised securities. We assess your realistic threat landscape: insider risk, physical access controls, phishing and blind signing exposure, supply chain risk (for hardware devices), and regulatory enforcement risk.
Your current setup is evaluated against the appropriate standard for your asset value, regulatory exposure, and recovery time objectives. Gap analysis produces a prioritised list of findings with severity ratings — not a 200-page document nobody reads.
Every audit concludes with a remediation roadmap and a compliance evidence package. The evidence package is structured to address what SEC examiners, NIS2 auditors, and DORA supervisors actually ask for: custody documentation, key management procedures, tested recovery timelines, and integrity verification records.
Audit scope and cost vary significantly based on the number of assets in scope, the complexity of the custody setup, and the regulatory frameworks that apply. As a general framework:
Focused hardware wallet audit (single team, standard custody setup): typically 1–2 days of advisory engagement, covering key storage review, signing controls, and device selection rationale.
Full enterprise custody audit (multi-entity, cold storage architecture, regulatory alignment): 5–10 days, producing a comprehensive evidence package and remediation roadmap.
Regulatory preparation engagement (SEC/NIS2/DORA exam prep): scoped to your examination timeline, producing the specific documentation your regulator asks for.
CryoVault does not publish standard rates because every engagement is scoped individually. Contact us with your asset type, regulatory context, and team size for an accurate scoping conversation.
A standard IT security audit evaluates network perimeter, access controls, patch management, and software vulnerabilities. A crypto security audit does overlap with these areas — but it adds a set of concerns that generic IT auditors typically do not cover:
