QL Security: AI cybersecurity and governance for UK organisations

QL Security, the trading name of Quantum Leap Security Limited, is a British company based in Stamford (United Kingdom) that presents itself as an AI security partner. Its activity focuses on helping organisations manage the risk arising from the use of AI, covering everything from initial assessment to the implementation of technical controls and continuous monitoring. The firm operates under the legal name Quantum Leap Security Limited, registered in England and Wales with number 16896166.

AI security services

The company structures its offering into three areas: advisory, implementation and managed services. Among the specific services it details are:

• AI Security Gap Analysis: a point-in-time assessment of security posture, delivering an AI Security Scorecard and a prioritised roadmap to close critical gaps.
• AI Security Programmes: ongoing governance, security operations and oversight through a Virtual AI Risk Officer, AI supplier risk management (AI Supplier TPRM Programme) and continuous monitoring.
• AI Security Projects: Shadow AI Discovery, AI penetration testing, LLM Guardrails Deployment and agent and MCP security.
• AI Behaviour Verification: independent, ongoing verification of AI system behaviour, with prompt injection testing, jailbreak detection, data leakage probing, agent and MCP security testing, and evidence reports for audits.
• AI Act Preparedness: risk classification, compliance roadmap, documentation support and ongoing monitoring to comply with EU and UK regulation.
• ISO 42001 Implementation: implementation of the international standard for AI management systems, from gap analysis through to certification readiness, including liaison with external auditors and ongoing maintenance.

Standards and frameworks

The firm aligns its services with a set of standards and regulations, among which it mentions: Cyber Essentials, EU AI Act, EU GDPR, ICO AI Guidance, ISO 27001, ISO 42001, NCSC CAF, NHS DSPT, NIS2 Directive, NIST AI RMF, OWASP AI Top 10, SOC 2, UK AI Act and UK GDPR.

Approach and methodology

QL Security describes an AI security maturity journey structured in five stages: understand exposure (which AI tools are used and what risks exist), govern (policies, ownership and governance frameworks), comply (UK and EU AI Act requirements), secure (technical controls, vulnerability testing and guardrails) and assure continuously (monitoring, regular assessments and continuous improvement). The company maintains that its proposition integrates advisory, implementation and managed services under one provider, so that assessments lead directly to deployments and policies connect to technical controls.

Founders and recognition

The company was founded by Jason Holloway, co-founder and managing director, and John Airey, co-founder and commercial director. In September 2026, Jason Holloway was named an innovator in the Peterborough Top 100, in the Innovation category, at the Chamber of Commerce centenary dinner. The company publishes analysis and guides on AI governance, such as articles on the obligations of the EU AI Act for providers and deployers, and on emerging AI leadership roles.
