Doing security differently since 2005
Professional Security began with first-hand experience of the frontline.
Before founding the business, David Fullerton worked as a Door Supervisor across Leeds. He saw an opportunity to raise industry standards by building a security company centred on professional service, responsible employment and respect for the people doing the job.
In 2005, David and Abby Fullerton founded Professional Security with a clear ambition: to provide clients with dependable, well-supported security teams while creating a better working environment for frontline professionals.
Today, we support hospitality venues, retail and leisure destinations, commercial premises, major events and stadia across the UK and Ireland.
Our growth has been shaped by exceptional people and long-term client relationships. From independent venues to complex multi-site portfolios, we work as an extension of our clients’ teams – protecting their people, premises, customers and reputations.
Part of Fullerton Group
Professional Security is the original business at the heart of Fullerton Group, which brings together specialist security, training and risk-management companies.
We retain our sector expertise and customer-focused approach while benefiting from shared central services across marketing, finance, recruitment, vetting and screening, compliance, technology and HR.
This gives our clients the personal service and specialist knowledge of a dedicated security partner, backed by the infrastructure, resources and stability of a wider organisation.
Expertise built around our clients
Our leadership team brings together experience from security, hospitality, retail, events, stadia and complex commercial operations.
This means we understand security from both the provider’s and the client’s perspective. Every solution is shaped around the premises, operating model, customer journey, risk profile and service expectations involved.
Our services include:
- Door Supervision
- Security Guarding
- Close Protection
- Event Security and Spectator Safety
- Retail Security and Loss Prevention

Responsible employment and transparent payroll
Our frontline colleagues are directly employed through PAYE. We do not operate a cash-in-hand employment model.
By managing payroll directly, we maintain clear employment records, correctly process tax and National Insurance contributions, and provide our colleagues with the employment protections and statutory benefits they are entitled to.
This transparent approach gives clients greater confidence in their security supply chain, reducing the risks associated with false self-employment, unclear subcontracting arrangements and non-compliant labour providers.
