Specialist security services



First Security is uniquely placed to adapt its resources and blend its security services to perfectly match the demands of our clients’ environments. We offer a range of specialist security services from close protection, to penetration testing. Ensuring that people feel safe, buildings are secure, and the working communities are supported. It’s this personal delivery that allows us to deliver smarter security every day.

Close Protection

First Security provides cost-effective close protection services in the UK to our private clients: 
  • Close protection officers fully trained to SIA standards and vetted to BS 7858.
  • Advanced drivers to chauffeur our clients.
  • Full executive protection trained security teams.

Penetration Testing

Penetration testing involves breaking into an organisation to expose possible weaknesses in security. From that, we can work out how to prevent future intrusions. Our testing includes:
  • A fully documented test plan, so we can agree an acceptable level of intrusion.
  • Agreed rules of engagement.
  • Immediate notification if the test results expose any critical security flaws.
  • Full executive summary report of all our findings.

Store Detectives

Specifically trained retail Security Officers with substantial experience within the retail environment are equipped with the additional training and the necessary expertise to optimise loss prevention.

Executive Protection

First Security provides a professional executive protection service tailored to the individual requirements of our clients with the emphasis on maintaining a low, or covert profile, minimising attention and disruption. We provide a professional service that plans, manages and carries out the full assignment.

Surveillance and Counter Surveillance

At First Security we understand that an executive protection team does not always suit a client’s lifestyle or plans, but that our clients may still require protective surveillance. This covert executive protection or ‘protective surveillance’ team then carries out counter surveillance and protective intelligence duties to ensure the clients complete safety and security.

Workforce Infiltration

We provide covert operatives who work within workforces where there are security issues, a solution used frequently in the retail and logistics sectors, it can be applied to many environments. We can also provide covert operatives who can converse in different languages so that they reside seamlessly within any working environment.
