01
The brief
A security company running on infrastructure it would not have signed off for a client: shared credentials, manual deploys, alerts nobody read.
02
The build
Migration to hardened bare-metal hosts, containerised services, zero-trust access with short-lived credentials, CI/CD with one-command rollback, and monitoring tuned so an alert means something.
03
The result
In progress. Access is already zero-trust and deploys are boring; the monitoring cut-over lands next.
