Europe moved from fragmented national rules to a harmonised framework faster than any other major market, and the practical effect for security work is that European engagements are documentation-heavy, evidence-driven and increasingly tied to formal ICT risk requirements.
The European market now asks a specific question: can you demonstrate, in a form a supervisor accepts, that this system and the arrangements around it are sound. That favours firms who document methodology, scope and evidence properly, and it disadvantages the report-as-marketing-badge approach that the industry tolerated for years. It has been good for the quality of security work in the region.
European engagements cluster around three groups. Issuers of tokens and stablecoin-type instruments, where authority structure, redemption and reserve-related technical claims dominate. Service providers — exchanges, custodians, brokers — where custody architecture, segregation and operational controls dominate. And financial institutions bringing blockchain systems inside an existing ICT risk framework, where the integration and third-party dependency questions dominate.
We work European hours, contract in EUR or USD, and produce reports written for circulation: to a supervisor, to an internal audit function, to an enterprise counterparty, or to an insurer. Findings can be mapped to the control frameworks a European institution already runs on so they enter an existing register rather than starting a new one.
Regulatory references describe the general shape of a regime and are not legal advice. Requirements change; confirm your obligations with your own counsel and supervisor.
We fix a commit hash, agree the in-scope contracts and read your architecture docs, then build a threat model: who the actors are, what the trust boundaries are, and which invariants must never break. Nothing is reviewed against assumptions we have not written down.
Line-by-line review by at least two auditors working independently, focused on authorisation, accounting, upgrade paths, external integrations and the gap between what the code does and what the documentation claims it does. Most critical findings come from this phase, not from tooling.
Static analysers appropriate to the language, plus property-based fuzzing and invariant testing to push the system into states no unit test covers. Tooling is used to widen coverage, never to replace the manual pass.
Candidate findings are proven on a forked network with a working proof of concept. We report what an attacker can actually do and what it costs them, not a theoretical severity label.
Every finding gets a severity rating, reproduction steps, the affected code, the impact in concrete terms and a specific remediation. You get a draft for discussion before anything is finalised.
We re-test every remediation against the original proof of concept and check that the fix has not opened a new path. The final report is yours to publish.
We deliver the technical assessment and evidence — code audit, custody review, infrastructure testing and control effectiveness — structured so your compliance function and counsel can map it to your obligations. We do not provide legal or regulatory advice.
Yes. We map to ISO 27001 control families and your internal taxonomy so blockchain findings sit in the same register as the rest of your ICT risk.
Yes, and for vendors selling into European institutions it is often the fastest commercial return on the engagement — the review clears faster with an independent assessment already in hand.
Reports are written in English, which is standard for technical assurance across the EU. Debriefs run in English; we can accommodate an interpreter where a team prefers it.
Yes — the deployment, the custody model, the integration into core systems and the third-party dependencies, with evidence packaged for internal audit.
A repository or contract address, a commit hash to freeze the scope, whatever architecture or spec documentation exists, and a point of contact who can answer design questions. If documentation is thin we will write our understanding of the system back to you and ask you to confirm it — that step alone catches design-level bugs.
A single token contract is 24–48 hours. A typical dApp or mid-sized protocol runs one to two weeks. Large DeFi systems, L2s, bridges and ZK circuits are scoped per project after we have seen the code. We will give you a fixed timeline with the quote, not an estimate that moves.
