Welcome to Diama Security
– Trusted. Proven. Prepared.
At Diama Security, we are proud to be recognised as a leading provider of professional security services across the UK. With a steadfast commitment to protecting our clients’ assets, properties, and people, we deliver tailored security solutions built on operational excellence, discretion, and trust.
Our experienced team, comprised of former military, police, and industry specialists, delivers a wide range of services including Executive Protection, Behavioural Detection Officers (BDOs) trained in early threat identification, and Spectator Safety Officers deployed across major stadia and public venues to ensure safe, compliant, and enjoyable experiences for all attendees.
We don’t offer one-size-fits-all solutions. We listen, assess, and implement bespoke strategies that align with your specific risks and operational requirements, whether protecting high-profile individuals, managing dynamic crowd environments, or safeguarding critical infrastructure.
In light of the recently enacted Protection of Premises Bill, which has now received Royal Assent, we are actively supporting clients in meeting the new regulatory obligations. From comprehensive security risk assessments to integrated protective measures and response planning, Diama Security remains at the forefront of ensuring compliance and resilience under the evolving legal framework.
When security matters, trust Diama.
