Kelderbridge
Films about Kelderbridge, a fictitious UK unitary council. It is a full model council: three sites, its own network, services and records. It is used to work out how a council's technology should be designed, secured and run, and every decision is kept in one design database.

How the council's data is protected against ransomware and how it would recover: locked backup tiers, integrity baselines, and restoring into a clean room before anything goes back into service.
The vault and the keys 5:58
Where the council's secrets and encryption keys live, who holds them, and how an application gets a key it needs without anyone handling it by hand.
One email's journey 5:12
An email from a resident followed from the internet to a caseworker's screen: every zone, firewall and check it passes through on the way.
