AI Governance Gateway · Built for the EU

Control the data your enterprise
sends to AI.

Sovereign Guard is the compliance middleware that tokenizes PII, enforces policy, and audits every prompt — before it ever reaches OpenAI, Anthropic, or any LLM.

  • EU AI Act
  • GDPR
  • DORA
  • Zero-trust · On-prem
The pain

You don't actually control what leaves your network.

Your teams already paste customer records, contracts and source code into ChatGPT and Claude. That data leaves the EU, lands on third-party servers, and you have no record it ever happened.

🕳️

Shadow AI everywhere

Staff use whatever LLM is fastest. Sensitive data flows out through channels security never approved and can't see.

🌍

Data leaves the EU

Prompts containing PII are processed by US providers. For EU financial institutions that's a residency and lawful-basis problem on day one.

📭

No audit trail

When a regulator or DPO asks "what personal data did you send to AI, and on what basis?", there is no answer to give.

Why now

The regulation already landed. The clock is running.

The EU AI Act (Regulation 2024/1689) is now in force and phasing in alongside GDPR and DORA. Using AI without governance is no longer a grey area — it's an exposure.

€35M

or up to 7% of global turnover — the ceiling for EU AI Act penalties for prohibited practices.

2026

high-risk AI obligations phase in. Controls, documentation and audit trails must exist before, not after.

overlapping regimes — EU AI Act, GDPR, DORA — now scrutinise how financial entities use AI and manage ICT risk.

The institutions that adopt AI safely will move fastest. The ones that don't will either freeze AI entirely or carry a liability they can't measure. Sovereign Guard turns "we can't risk it" into "we're covered."

The product

A control plane between your people and the AI they use.

Sovereign Guard sits quietly in the middle. Every request to an AI model or connected tool passes through it first — so sensitive data is protected, your rules are applied, and everything is recorded.

  • Protects sensitive data before it ever leaves your walls.
  • Enforces your policies on what AI can and cannot be used for.
  • Audits every interaction in a tamper-evident record you can hand to a regulator.
  • Lets you say yes to AI without betting the bank on it.
Under the hood

The governance gateway you wish already existed.

An on-prem, zero-trust pipeline that runs inside your infrastructure. PII never leaves in identifiable form — and you can prove it.

🔐

PII Detection & Tokenization

Microsoft Presidio + custom EU recognizers detect IBAN, SWIFT/BIC and national IDs, then replace them with reversible tokens. Mappings are encrypted on-prem.

⚖️

Policy Engine

Open Policy Agent evaluates every request before dispatch, with a versioned EU AI Act policy catalogue, dry-run and rollback.

🧾

Immutable Audit Log

Every interaction sealed in a SHA-256 hash chain. Tamper-evident, independently verifiable, retained for the regulatory period.

🔀

AI Provider Proxy

Smart routing across OpenAI and Anthropic with a circuit breaker — failover that never bypasses the compliance pipeline.

🧩

Governed MCP Proxy

Tool calls and agent actions flow through the same controls, so autonomous workflows stay inside policy.

🗝️

Keys Never Leave

HSM/KMS-backed key custody, per-tenant separation, and crypto-shredding for verifiable erasure. Your keys, your boundary.

Where we are

MVP shipped. Looking for the partners who feel this pain.

The core engine works today. We're raising and partnering to harden it into the product a tier-1 EU bank will deploy — and we want design partners and investors who get it.

  1. MVP Done

    PII tokenization, OPA policy engine, hash-chain audit, AI + MCP proxies, GDPR endpoints and RBAC — running end to end.

  2. Now In progress

    Production hardening: enterprise SSO, HSM/KMS key custody, multi-tenancy, EU data residency and the compliance evidence pack.

  3. Next Design partners

    Pilot deployments with EU financial institutions. Detection-quality SLOs, DORA resilience testing, certification roadmap.

  4. Scale Funded

    Marketplace of policy packs, multi-region, and turnkey procurement evidence for security, risk and DPO review.

Investor, design partner, or just someone who's felt this pain?
