Security for the AI era — and everything it touches
AI is our focus, not our limit. ACE-NSI Cybersecurity combines 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.
Compliance & vCISO
Compliance posture management, third-party risk and executive security leadership on demand — without the full-time hire.
Vulnerability & Patching
Move from scanning to remediating. Prioritised, validated exposure with automated patching and patchless protection.
Secure Web Browsing
Protect the place where work — and AI agents — actually happen: the browser. Isolate high-risk sessions and apply browser DLP.
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.
Deception & Intelligence
Lure adversaries into realistic decoy environments, study what they do and turn it into high-fidelity threat intelligence.
Assess. Govern. Monitor.
A simple loop that turns AI ambition into a security programme you can evidence.
Map your exposure
Discover the AI tools, data flows, vulnerabilities and human risk across your estate. Get a scored, prioritised report within weeks.
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.
Run it for you
Our managed service watches, remediates and reports continuously — so your board sees measurable risk reduction, not just activity.
We think like attackers, so you stay ahead
