Our mission
Eliminate the risk of non-compliance for every UK security company
Operating with unlicensed or expired security personnel is not just a regulatory risk — it is a legal liability. Fines, lost contracts, and reputational damage are real consequences that security companies face every day.
Guard Checker was founded to solve this problem. We connect directly to the official SIA public register to verify every licence in your workforce automatically. No manual lookups. No guesswork. Just continuous, reliable compliance monitoring.
Whether you are a sole trader running a small door supervision team or a national company managing thousands of operatives across multiple sites, Guard Checker scales to fit your operation.
What drives us
Our values
Compliance first
Every feature we build starts with one question: does this make it easier for security companies to stay compliant? Regulatory adherence is not optional — it is the foundation of our platform.
Simplicity over complexity
Managing SIA licences should not require training manuals. We design every screen to be intuitive, fast, and accessible — whether you manage 10 operatives or 10,000.
Security by default
We handle sensitive workforce data. Every record is encrypted, access is role-controlled, and our infrastructure meets enterprise-grade security standards. Your data never leaves the UK.
Built for the industry
We understand the challenges of running a security business. Guard Checker is built by people who know the sector — shift patterns, ACS audits, client compliance requirements, and the realities of frontline operations.
