Built on professionalism, discretion and trust.

DECKO is led by former military operators with extensive covert surveillance experience, bringing operational discipline and field-proven tradecraft to every case we take on.

Our operational footprint covers west central Scotland, including Glasgow and the surrounding areas. We work quietly and methodically, building cases that stand up to scrutiny while protecting our clients' privacy at every step.

Every enquiry is handled with professionalism, discretion and full compliance with UK law — from private clients navigating sensitive personal matters to businesses requiring rigorous investigation and security support.
