Why we built it
Clarity first, then security.
Most small and mid‑sized businesses do not have a full picture of the technology they depend on — who controls it, where it lives, and what is at risk. We built CentroKey to give owners that picture in plain English, and then to help them act on it. We store the map, never the keys, and everything is hosted in the UK.
What we stand for
- Plain English over jargon
- UK‑hosted, UK GDPR
- We store the map, never your keys
- Honest about what software can and cannot do
Two products, one platform
CentroKey Vault and CentroKey Sentinel
CentroKey Vault
Know who holds the keys to your business. A living register of every domain, login, supplier and renewal — and who controls what.
CentroKey Sentinel
Find the weakness before they do. AI penetration testing, attack surface monitoring and vulnerability management in one platform.
