Welcome to AD Porta, the railway security specialists

Dedicated railway security

We are a privately-owned, dedicated railway security specialist  working closely with blue chip rail construction companies and London Underground, providing a range of security services to major rail and Tube projects in the London area,  as well as trackside security during upgrade and enabling works.

Unlike many other security firms, we operate exclusively in the rail industry, so we fully understand the pressures to hit stagings and to ensure all projects run smoothly.
BSI and UKAS accreditated

Quality Assured

We actively recruit ex-military and police personnel, guaranteeing the quality of our guards.

We are so confident in our personnel that we regularly perform penetration audits on our sites and constantly monitor and improve our service.

Customer satisfaction

As part of our commitment to customer care and satisfaction we periodically ask clients to complete a customer satisfaction survey. We use their feedback to help us assess how well we are doing and to ensure we exceed service level agreements.
