A harbor is judged by one measure: what holds when the weather arrives.
Nineharbor is an independent practice for the security and governance of intelligent systems.
We test AI the way adversaries approach it, and govern it the way regulators read it.
Every finding evidenced. Every control demonstrated. Every claim one an auditor can stand behind.
Built inside regulated financial services and now serving institutions that must answer for the AI they deploy - to boards, to auditors, and to the regulators of the UK, EU and GCC.
Hands-on adversarial testing of AI systems: prompt injection and agentic attack paths, model and pipeline hardening, LLM application review, and secure-build verification. Findings arrive reproduced, evidenced, and mapped to the frameworks your auditors use.
Classification and conformance against the EU AI Act, ISO/IEC 42001 and NIST AI RMF, with privacy obligations mapped across UK and EU GDPR, the Bahrain, Saudi and UAE PDPLs, India DPDP and Singapore PDPA. Governance written for the regulator who will actually read it.
Verifiable proof that controls hold: boundary and egress enforcement, grounded outputs, audit-ready evidence trails. Not a statement that a control exists, but a demonstration that it held when tested.
Design and review of AI agent architectures that run locally with zero data egress, keeping models, prompts and records inside your estate. Built for institutions where data sovereignty is a requirement, not a preference.
Every engagement is delivered against named provisions of the applicable frameworks, across the UK, EU, GCC and Asia, so findings translate directly into your compliance position.
I spent twenty-five years on the institution's side of the audit table. Nineharbor exists so that when an institution says its AI is secure and governed, the statement is not a hope - it is a demonstrated, evidenced fact.
No vendor alliances, no resold tooling, no incentive to find what a partner sells. Assessment and attestation only mean something when the assessor has nothing else to gain.
Our tooling runs inside the boundary. Client data, prompts and findings never transit a third-party cloud, which is precisely what we would tell you to demand of anyone else.
Every finding is reproduced, sourced to a primary text or a demonstrated exploit, and verified before it reaches you. If we cannot ground it, we do not report it.
We have sat on the institution's side of the audit table across the GCC and UK, and we write findings for the people who will sit across it from you.
A first conversation is free, confidential, and usually tells you within an hour whether the risk you suspect is real.
