FAQs

How can a tailored high-security system benefit my organisation?

Standard security solutions may not meet the strict regulatory and operational requirements of sensitive sites like airports, police stations, or government facilities. SECOM designs tailored high-security systems that ensure compliance with industry standards while providing robust protection against potential threats.

Our expert teams conduct thorough assessments to identify vulnerabilities and implement bespoke solutions, from access control to advanced surveillance. Whether securing critical infrastructure or law enforcement facilities, our systems can adapt and grow to your evolving security and compliance needs.

Why choose SECOM for designing and installing high-security systems?

With over 60 years of experience in the security industry, SECOM has become a trusted name in protecting high-profile and sensitive sites. As a Gold member of the National Security Inspectorate (NSI), we uphold the highest standards in security design and installation.

Whether it’s an integrated airport security system or advanced access control for a government building, our team is equipped with the expertise to deliver customised solutions that meet your specific needs.

We have a deep understanding of the very special security needs of high-profile sites across the country. Often, their security needs are outlined in regulation and legislation due to their importance — like key national infrastructure for example. We have significant experience in building systems to meet those security and compliance needs.

For example, one of our clients maintains vital utility structures in the UK, and often sends accredited engineers on-site. Our remote monitoring teams can watch the CCTV to ensure the minimum number of engineers are on site when work is conducted, providing proof of compliance and peace of mind.

Who does SECOM protect?

While we can’t freely discuss the clients we are protecting today, we have worked on securing some of the most important pieces of British infrastructure, such as Heathrow Terminal 5 or the Channel Tunnel station at St. Pancras.

We protect a wide variety of institutions (judicial, financial, government etc.) on a daily basis to their exacting and rigorous standards.
