What we do

Security for the AI era, and everything it touches

AI is our focus, not our limit. We combine advisory, managed services and carefully chosen technology into one programme you can actually run.

AI Security, Governance & Controls

Discover shadow AI, stop sensitive data leaking into GenAI, and build governance aligned to ISO/IEC 42001, NIST AI RMF and the EU AI Act.

With Harmonic · AIBound

Compliance & vCISO

Compliance posture management, third-party risk and executive security leadership on demand, without the full-time hire.

Delivered by ACE-NSI consultants

Vulnerability & Patching

Move from scanning to remediating. Prioritised, validated exposure with automated patching and patchless protection.

With Vicarius

Secure Web Browsing

Protect the place where work (and AI agents) actually happens: the browser. Isolate high-risk sessions and apply browser DLP.

With Menlo Security

Awareness & Human Risk

Go beyond tick-box training. Measure real security behaviour, run AI-era phishing simulations and nudge people in the flow of work.

With CybSafe

Deception & Intelligence

Lure adversaries into realistic decoy environments, study what they do and turn it into high-fidelity threat intelligence.

With CounterCraft
How we work

Assess. Govern. Monitor.

A simple loop that turns AI ambition into a security programme you can evidence.

01 · ASSESS

Map your exposure

Discover the AI tools, data flows, vulnerabilities and human risk across your estate. Get a scored, prioritised report within weeks.

02 · GOVERN

Set enforceable policy

Design governance, controls and an approved AI roster aligned to ISO/IEC 42001, NIST AI RMF and the EU AI Act, then enforce it technically.

03 · MONITOR

Run it for you

Our managed service watches, remediates and reports continuously, so your board sees measurable risk reduction, not just activity.
