Visible health

A server you can actually see at a glance.

Every engagement ends with a basic, real-time view of CPU, memory, disk, and uptime — no opening a terminal to check.

Hardening baseline

Six switches every production server needs.

Default-on in our setup. Documented in your runbook.

Verified with a fresh SSH session after handover
Switch 01

SSH keys only

Password auth disabled, root login off, port hardened.

Switch 02

UFW firewall

Default-deny, explicit allowlists, IPv4 + IPv6.

Switch 03

Unattended upgrades

Security patches auto-installed, reboots scheduled.

Switch 04

Fail2ban

Bruteforce protection for SSH, Nginx, common services.

Switch 05

Non-root sudo user

Workflows under a deploy user with explicit sudo.

Switch 06

Log rotation

journald + logrotate sized to the disk you actually have.

Real config, not snippets

An Nginx vhost we actually deploy.

SSL, HSTS, gzip, proxy headers, and rate-limit defaults included — handover-grade, not toy.

/etc/nginx/sites-available/app.conf● nginx -t passed
server {
  listen 443 ssl http2;
  server_name app.yourco.com;

What we run

Six things we set up alongside the app.

From the boring nightly to the rare emergency — everything has a playbook.

Op 01

Deploys

Git-driven, PM2 / Docker / systemd as suits the runtime.

Op 02

Nginx

Reverse proxy, SSL termination, redirects, multi-app routing.

Op 03

SSL renewal

Let's Encrypt via certbot, automated, alerting on failure.

Op 04

Backups

Restore-tested DB + uploads. Off-server. Documented.

Op 05

Health checks

Uptime + disk + process supervision with alerting.

Op 06

Incident handling

Run-now playbooks for OOM, disk full, runaway process.

Tool belt

The tools we keep on every server.

No surprises in your handover — everything below is documented and named.
