Engineering
How PRESIDIO engineers
for compliant AI.
We build the hardened layer beneath AI systems — libraries, architectures, and assessments for organisations that cannot afford to get this wrong.
Practice areas
What we work on.
Secure agentic payments
Pre-execution compliance gating for AI agent payments — PII and policy screening before a request is signed, with cryptographic evidence. Underlies our x402 work and the live screening API.
AI governance & assessment
Frameworks, audits, and evidence packages for teams that have to demonstrate compliance rather than claim it. Built on the IKI-Gov reference model and aligned with the EU AI Act and ISO/IEC 42001.
Architectural transparency & cloud posture
Observability and bounded behaviour for production AI workloads, plus continuous cloud-posture audit. Why a system behaves the way it does, visible by design rather than by retrofit.
Hardened foundations
Web, API, industrial, and embedded libraries — the unglamorous layer under everything above. TLS enforced, timeouts required, audit logs on, defaults that hold up in production.
Method
How we work.
Standards-first.
We write to published specifications — OWASP ASVS, IEC 62443, x402, OPC UA security profiles. If a specification is wrong for your case, we say so on the record instead of inventing a private alternative.
Auditable evidence.
Every deliverable ships with a reproducible audit. What we claim is what you can verify — with the same inputs, on your own machine.
Runbooks over tribal knowledge.
We write down how to operate what we build. No tribal knowledge transfer, no one-person dependencies, no consulting retainer disguised as documentation gaps.
Open source, by default.
Deliverables ship under open licenses unless there is a specific reason otherwise. Your team inherits the work, not our hours.
