Calibre

Calibre is a certification body based in London that helps technology companies obtain ISO 27001 certification on short timescales. Its process is designed for startups and fast-moving businesses: the audit scope is defined in hours rather than weeks, and the certification decision and certificate are delivered in days rather than the months typical of conventional audits. The service is built to work alongside clients' existing tools and systems, and is structured so that compliance work does not hold up product roadmaps.

The company describes its operation as AI-native, with artificial intelligence embedded across its internal processes. Auditors concentrate on the decisions that require human judgement; a named lead auditor and an impartial certification decision lead are assigned to each engagement, preserving the independence of the certification decision. The team draws on experience from both sides of the audit table, spanning security, compliance, startup operations and large AI deployments.

Technical domains covered by the business include information security, compliance and certification auditing, AI management systems and AI-native operations. Its stated market focus is technology companies, startups and fast-moving businesses.
