GDPR for Security Companies: A Practical Guide

What UK GDPR means for security guarding firms — handling staff and CCTV data, lawful basis, retention and the records buyers increasingly ask about.

Category: Compliance · Published: 2026-06-14

Security firms handle a lot of personal data — staff vetting records, biometric check-ins, CCTV, incident details. UK GDPR sets the rules for handling it. This guide covers the practical essentials.

What data security firms hold

Guarding companies process more personal data than they often realise:

  • Employee records, including sensitive vetting and screening data.
  • Biometric data where facial-recognition check-in is used.
  • Location data from GPS check-ins and live tracking.
  • CCTV footage and incident details involving members of the public.

Lawful basis and consent

Every processing activity needs a lawful basis. Employment and compliance obligations often provide one for staff data, but special-category data (like biometrics) needs extra care and usually explicit consent and a clear necessity.

Document why you process each category of data and on what basis.

Data minimisation and retention

Only collect what you need, and keep it only as long as you need it. Continuous location tracking, for example, should be limited to when it's genuinely necessary and retained for a defined, justifiable period.

Set retention periods and delete or anonymise data when they pass.

Rights, security and accountability

Individuals have rights over their data — access, correction, erasure in some cases. You also need appropriate security measures and the ability to evidence your compliance.

Buyers in regulated sectors increasingly ask about your data handling during procurement, so good GDPR hygiene is also a sales asset.

Frequently asked questions

Does GDPR apply to small security firms?

Yes. UK GDPR applies regardless of size whenever you process personal data, which all guarding firms do.

Is facial-recognition check-in allowed under GDPR?

It can be, but biometric data is special-category data. You need a clear lawful basis (usually explicit consent and necessity), data minimisation and appropriate security.

How long should I keep vetting and location data?

Only as long as necessary for the purpose. Define retention periods, justify them, and delete or anonymise data once they expire.

Is this legal advice?

No. This is general guidance — consult the ICO's resources and, where needed, a qualified data-protection adviser for your specific situation.
