About AuthHub
AuthHub is a purpose-built Fine-Grained Authorization service tailored for modern software suppliers. Powered by high-speed cloud clusters, our platform is engineered around Google Zanzibar-inspired ReBAC models and strictly adheres to AuthZEN standards.
While AuthHub represents the cutting edge of modern authorization, our foundational expertise was forged over decades in the trenches of complex, large-scale enterprise security.
Our Heritage: Deep Enterprise IAM Roots
The AuthHub team's DNA is rooted in high-level identity security, having operated as a specialized consultancy dedicated to delivering state-of-the-art IAM solutions to enterprises across Europe, the Middle East, and Africa (EMEA).
As specialist consultancy in the EMEA region, our founders brought over 20 years of combined Identity and Access Management experience to the table.
- We have successfully executed and guided various very large-scale and complex national and international IAM engagements.
- We intimately understand the political and organizational challenges that are inherent to most large security and IAM projects.
- We know that a successful project requires not just outstanding technical expertise, but effective governance, robust executive sponsorship, and organizational discipline.
Our Architectural Philosophy
We approach Fine-Grained Authorization with a battle-tested perspective on system design. Our core technical philosophies have remained consistent throughout our evolution:
“A successful architecture must be elegant, scalable, and adaptable enough to respond to evolving business and regulatory demands.”
- Our architectural philosophy heavily emphasizes simplicity and elegance.
- We are firm proponents of loosely coupled architectures that promote agility by embracing open standards and minimal customization.
- We recognize that highly customized and over-engineered security solutions have a tendency to become unmanageable over time.
- We understand that business processes and organizational needs are extremely fluid, demanding infrastructure that scales cleanly.
Proven Industry Expertise
Our unique set of best practices and implementation guidelines is backed by vast experience delivering complex enterprise solutions across a wide range of industry verticals. We have secured identities and built infrastructure for:
NIST Security Framework Alignment
AuthHub's architecture is designed against the latest NIST security standards. Independent assessment confirms strong alignment with NIST CSF 2.0, NIST SP 800-207 (Zero Trust), and the NIST AI Risk Management Framework.
Zero Trust Architecture (NIST SP 800-207)
NIST mandates dynamic, continuously-evaluated access decisions. AuthHub implements a Three-Clock Governance Pattern that eliminates temporal drift:
- ✓ Event-time triggers — structural changes detected and access suspended in <500ms
- ✓ Attestation-time signatures — dual-gate re-attestation with environmental condition tracking
- ✓ Execution-time admissibility boundary — inline staleness and drift checks on every evaluation
- ✓ Consistency tokens — Zanzibar-style Zeta tokens prevent the "New Enemy Problem"
- ✓ Namespace micro-segmentation — cryptographically-scoped boundaries prevent lateral access
AI Risk Management (NIST AI RMF & IR 8596)
AuthHub's AI-powered import pipeline implements NIST-recommended guardrails for generative AI systems:
- ✓ Prompt injection defence — strict Zod schema validation on inputs + structured JSON output enforcement
- ✓ Human-in-the-loop — mandatory UI confirmation before AI-mapped data is committed to the authorization graph
- ✓ PII egress filtering — DataScrubber middleware sanitises NHS numbers, emails, and structured identifiers before external API dispatch
- ✓ AI agent governance — registered agents with scope bounds, rate limits, and delegated authorization via SpiceDB caveats
Cybersecurity Framework 2.0 (NIST CSF 2.0)
AuthHub maps to all five CSF core functions:
| Function | AuthHub Implementation |
|---|---|
| Govern (GV) | Tenant-configurable governance policies, attestation workflows, environmental drift declarations |
| Identify (ID) | SCIM 2.0 identity lifecycle, AI agent registry, namespace-scoped asset inventory |
| Protect (PR) | ReBAC/FGA with SpiceDB, mTLS, namespace isolation, HSM-backed keys, rate limiting |
| Detect (DE) | Real-time audit streaming via Kafka, AI anomaly detection (Log Sentinel), Prometheus alerting |
| Respond (RS) | Break-glass (AARP), automatic suspension on structural changes, admissibility boundary denials |
Standards & Interoperability
AuthHub implements open standards for enterprise interoperability — validated by the OpenID Foundation conformance suite:
- ✓ OpenID AuthZEN 1.0 — standards-based policy evaluation with SARC model (120+ conformance tests passed)
- ✓ SSF / CAEP 1.0 — Shared Signals Framework for real-time security event streaming (conformance tested)
- ✓ OpenID Connect Core 1.0 — Authorization Code Flow with discovery, PKCE, and key rotation
- ✓ OAuth 2.0 DPoP (RFC 9449) — Sender-constrained tokens resistant to theft and replay
- ✓ XAA / Cross-App Access (ID-JAG) — Enterprise IdP-mediated agent-to-app access without per-user consent
- ✓ Workload Identity Federation (RFC 8693) — Zero-trust token exchange for CI/CD and cloud workloads
- ✓ SCIM 2.0 — full identity provisioning with 18+ IdP support
- ✓ Google Zanzibar — proven ReBAC architecture via SpiceDB
- ✓ NHS CIS2 — Care Identity Service 2 federation for NHS Smartcard authentication
- ✓ NHS DSPT — Data Security and Protection Toolkit compliant (7-year immutable audit)
- ✓ UK GDPR — Right to erasure, data minimisation, processor agreements
- ✓ ISO 27001 / SOC 2 — available on Critical Infrastructure tier
