Defakto Security

Defakto (formerly SPIRL) is a non-human identity (NHI) security company that issues short-lived, cryptographically attested identities to workloads, services, CI/CD pipelines and AI agents in place of static secrets, API keys and long-lived service accounts. The platform is built on SPIFFE and ships two products: Mint, which runs Trust Domain Servers and Agents that mint X.509-SVIDs, JWT-SVIDs and proof-of-possession WIT-SVIDs for Kubernetes, Linux, Docker and serverless workloads under a dozen attestation methods; and Ledger, which discovers, risk-scores and eradicates static secrets across AWS, Azure, GCP, Kubernetes, Anthropic, OpenAI, Bedrock AgentCore and Gemini. The control plane is driven by a gRPC management API and the spirlctl CLI, with a Go SDK, an OpenTofu/Terraform provider, workload identity federation into AWS/Azure/GCP, and OCSF 1.8.0 audit logging.

Defakto Security is listed with 2 APIs on the APIs.io network. Tagged areas include Security, Identity, Non-Human Identity, Workload Identity, and SPIFFE.

The Defakto Security catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Defakto Security’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, signup flow, CLI, and 24 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

7 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 39.0 — up to +15.3 composite points
Access Clarity scores 34.2 — up to +13.2 composite points
Contract Governance scores 18.2 — up to +9.8 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/defakto-security/apis.yml: open an issue on github.com/api-evangelist/defakto-security to ask a question or point us at an artifact you publish.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
PKI and Encryption (certificate authorities, key management)	standard	26.8 (thin)	-	-
OpenID Certified Implementations (OIDC, FAPI, OpenID4VC)	standard	26.8 (thin)	-	-
Buf Schema Registry (public Protocol Buffers modules, gRPC / ConnectRPC schema publishers)	standard	26.8 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
