Systems Administration
We keep your systems steady, so you can focus on your work. We put your websites, accounts, and tools in order, document them, and look after them over time.

Start at any stage. We agree the scope and price before starting. All prices are plus tax.

Our tooling
Powered by FrontierStack
FrontierStack is a server-management app that Enfour built in-house, drawing on our experience running production services on Apple hardware since 1992. We use it to monitor the systems we look after for clients, so your servers, services, and devices are watched by the same tool we rely on ourselves.
Earlier detection
Monitors run on each host, so they keep watching even while our Mac sleeps. CPU, memory, disk, and crash trends are checked against a learned baseline, and alerts reach us on Slack, email, and more, so problems surface before they turn into outages.
Clearer visibility
Macs, Linux, and Windows servers and devices in one view, with health, alerts, and repair history on the same timeline. Diagnosis starts with read-only checks, and nothing changes without approval.
Better reporting
Measurements are kept as a 30-day history, and every change is recorded as the exact script that ran. We can also publish a status page for your sites and services, so you can see their health for yourself.
Passwords and keys stay in the macOS Keychain and are never shown to any AI. FrontierStack is also available to buy for your own team.
