Certification for the AI Era
Calibre is a modern certification body helping tech companies get ISO 27001 certified without derailing the roadmap.
Days to decision, not months
Tech-first auditors
We understand startups
IAF/IAS Accreditation*
The fastest way to certified
Scope in Hours
Tell us what the certificate needs to cover. We agree the boundary — teams, sites and systems — and set out the records the audit will call for, so nothing is a surprise on the day.
Audit in Parallel
Our system reviews evidence continuously. A named lead auditor focuses on the judgement calls only a human should make.
Certified in Days
If the audit is successful, an impartial certification panel issues your accredited certificate. You leave with credentials your enterprise customers trust.
Fluent in your stack
The first AI-native ISO 27001 certificate
We are built AI-native from the ground up in every process.
Traditional Certification Body
Traditional certification spends most of its time processing documents.
- Not made for startups
- Works with DocX back and forth
- Takes months to complete
- Inflexible with a legacy process
With Calibre
Calibre spends its time on the parts that need judgement.
- Built for startups from the ground up
- Plugs directly into your tools and systems
- Done in days
- We move with your business
Blended team from both sides of the table
Calibre came out of years spent inside security, compliance and startup teams, on both sides of the audit table. We built the certification process we always wished existed.
