Fail-Open Audit
Fast proof for your wallet flow or verifier: signature verification, nonce and audience binding, trust-list fail-closed behaviour, revocation and over-asking. A ranked findings memo, ready to act on.
What we do: independent penetration testing of the identity path — we find the flaw before an attacker does.
Independent offensive security for the European Digital Identity Wallet. We attack OpenID4VP, SD-JWT and mdoc for KYC and identity providers building verifiers, and banks and PSPs accepting them by 2027.
A sample digital-identity credential, shown for illustration only.
Every national wallet forks shared reference code; every verifier builds on it. The dangerous failures are often trust checks shipped switched off or optional: an unverified signature, a missing setting, a policy that accepts what it should reject. The verifier reports success while accepting a forged identity. That is fail-open trust. We hunt it before it reaches your customers.
An illustrative trust check that accepts an identity without verifying it.
The fraud of the wallet era won't be a fake passport.
It will be a verifier that said yes when it should have said no.
Four engagements for Europe's KYC and identity-verification vendors, wallet hubs, verifier providers, and DACH banks and PSPs: a two-week proof through to a standing retainer. Fixed scopes, senior operators, file-and-line proof — never a maturity score.
Fast proof for your wallet flow or verifier: signature verification, nonce and audience binding, trust-list fail-closed behaviour, revocation and over-asking. A ranked findings memo, ready to act on.
Deep testing of the whole wallet flow: OpenID4VP, SD-JWT VC, ISO 18013-5 mdoc, COSE/JOSE and the trust chain. Findings proven at source, mapped to AMLR customer due diligence and DORA, in a board-ready evidence memo.
Review and harden protocol choices, verifier configuration and fallback design before you ship. We show where your integration breaks. We advise and test; we don't build it.
Testing that keeps pace with your releases: every version checked, a retest calendar, and a signed assurance letter your own clients can rely on.
Readiness and evidence for the standards your buyers demand — DORA, ISO/IEC 27001, SOC 2 and GDPR — run by the same senior bench, so your security testing and your compliance story come from one team.
Independent by design. We never build a wallet, hub or verifier — so we can test everyone's.
You're shipping a wallet verifier your bank clients will scrutinise. We test it before they do — and give you an assurance letter you can hand to every prospect.
You must accept the EU wallet by 2027 and prove to your auditor it's secure. We test your integration end to end and map every finding to DORA and AMLR.
One weakness in your hub reaches every client on it. We test the trust chain at the core, independently.
One call, a fixed scope and fixed price.
Senior operators test the identity path at source level.
A ranked, file-and-line evidence memo mapped to DORA and AMLR.
One free retest within 90 days to confirm fixes.
A ranked findings memo with proof you can trace to the source and real-exploitability ratings; a remediation retest; and, on a retainer, a signed assurance letter for your customers and their auditors. Evidence, never a maturity score.
Generalists excel at web and mobile but treat wallets as login screens. Crypto-audit houses know protocols, not your MLRO or auditor. We bridge that gap with deep wallet-protocol testing, bank and AML fluency.
We test OpenID4VP, SD-JWT VC, mdoc and trust-list implementations at source level, with findings documented for each engagement.
Every report speaks to customer due diligence and DORA, not just CVSS. 15+ years in eID, KYC and AML sit behind it.
We build nothing in the ecosystem, so our word carries — to your board, your auditor and your clients.
File and line, reproduced by senior operators. If it doesn't survive verification, it doesn't ship.
Every finding mapped to DORA, ISO/IEC 27001:2022, SOC 2, GDPR, BSI C5, ISO/IEC 42001 and PCI-DSS: evidence for your board, regulators, customers and auditors, not a raw CVSS list.
Eight verifier checks, source standards and questions for buyers. Our public reference explains our testing focus; it is not a record of disclosed vulnerabilities.
Signature verification, nonce and audience binding, trust lists, revocation, holder binding and more — with source links and questions for your verifier vendor.

“Proof at source level,
not a maturity score.”
EU member states must offer wallets by end 2026; banks and regulated firms must accept them by end 2027. The AML Regulation applies in July 2027. KYC providers racing to become verifiers will face the same tender question: prove it is secure.

Illustration of what our testing surfaces — synthetic data, no real systems.
A sample credential separated into layers to show where a trust check can fail.
We helped build national identity. Now we break it — so it holds.
Founded on 15 years in electronic identity, KYC and AML. Our team has helped build two national digital identity systems from the inside. Deliberately small, deliberately deep: senior operators with national-scale build and break experience, not a sales layer.
A named lead with verifiable certifications on every engagement, backed by combined decades in penetration testing, cloud security, DevSecOps and incident response. Senior offensive-security and compliance operators, not anonymous staff augmentation.
They test your app and infrastructure. We test the identity trust chain most generalists treat as a login page — OpenID4VP, SD-JWT, mdoc, trust lists, revocation. We complement your existing testing, we don't replace it.
The standards are strong. The risk is in your verifier's configuration and fail-open defaults — which is exactly what we test.
DORA covers your ICT estate broadly. We go deep on the wallet and identity path, then map our findings straight back to your DORA and AMLR obligations.
No. We scope access to the minimum needed — flow, spec, or staging — always under NDA and handled under our ISMS.
Fixed-scope audits start quickly, and one senior operator replies to every enquiry — not a form robot.
Fixed scope. Fixed price. Senior-only. NDA-first. One senior operator replies.
Shipping a verifier or preparing to accept the wallet? Send us the flow you're worried about. One senior operator replies, not a form robot.
