PRESIDIO

Secure by construction

Hardened building blocks
for compliant AI transformation.

PRESIDIO engineers the payments, governance, and performance layers European organisations need to run agentic AI on defensible ground.

Flagship products

Three layers of the AI transformation stack.

Payments, governance, and performance — each hardened for organisations that have to prove what they run.

  • Agentic payments

    presidio-hardened-x402

    Secure and compliant HTTP payments for AI agents operating under EU rules.

    Available — the most mature library in the catalog.

    presidio-hardened-ikigov-assess

    A working framework for assessing AI systems against governance requirements.

    Launching mid-2026 alongside the companion Springer book.

  • Performance control

    presidio-hardened-arch-translucency

    A performance control framework for agentic workloads in the cloud — observable, bounded behaviour under load.

    Active development.

The brand word

What "hardened" means.

A library earns the PRESIDIO name when it follows these principles and ships with these defaults.

  • Open source, by default. Every library is public on PyPI with a SECURITY.md in the repo.
  • Standards-first. Built against OWASP ASVS, OPC UA security profiles, IEC 62443, and x402 — not in-house checklists.
  • Assessable. Every project ships with a reproducible audit and a runbook.

  • TLS on, validated, non-negotiable.

    No verify=False escape hatches. Modern cipher suites only.

  • Timeouts required.

    Every network call has a deadline; there is no default of "forever".

  • Safe deserialization.

    No pickle, no untrusted YAML, strict JSON only.

  • Audit logs without secrets.

    Security-relevant events are structured and logged; tokens, PII, and credentials are not.

  • A public SECURITY.md.

    Threat model, reporting channel, and disclosure policy — in the repo, not behind a contact form.

  • Reproducible audit.

    Every release has a dependency audit and a signed provenance record.
