The Defenaar difference

We secure what you build, and govern how it runs.

Assurance usually arrives in two halves: engineers who cannot speak the language of an auditor, and advisers who cannot read a Terraform plan. Defenaar holds both — a control designed in the console, written into policy, and evidenced in a form your certification body will accept.

Defenaar acts strictly as your adviser. Certification audits remain with your independent certification body — we prepare you for that room, we never sit on both sides of it.

Insights

Notes from the practice

All insights

30 July 2026

The breach came through the help desk

Why peripheral platforms — the ITSM tools nobody classifies — have become the softest route to your most sensitive client data.

1 July 2026

Your vendor switched on AI. Nobody told you.

Sixty-four percent of suppliers never disclosed new AI subprocessors. The annual vendor review has quietly stopped working.

23 June 2026

When AI fails quietly, the clock still starts

Article 73 of the EU AI Act gives high-risk providers as little as two days to report a serious incident — for a failure mode no SIEM was built to see.
