Network and security across six sites
Rebuilding a six-site network and the security around it, without closing a single branch for a day.
The challenge
Every device at every branch sat on one flat network, remote access was a shared password, firewall rules had grown by accident over years, and backups ran to a disk nobody had ever restored from. An insurance audit failed, which is how the conversation started.
What we built
We redesigned the network with segmentation per function, resilient links between sites and secure remote access behind MFA. Servers were consolidated onto managed virtualisation with patching and immutable, tested backups.
Monitoring and alerting now cover every site, and the estate is documented with runbooks the client's own IT staff use. We handed over training and a rehearsed incident plan, and continue to manage patching and monitoring.
- Unplanned site outages
- 0
- Since the new network went live.
- Tested restores

- Backups are verified by restoring, not by a green tick.
- Remote access behind MFA
- 100%
- Shared credentials removed entirely.
What it runs on
