The Proxmox Web UI Hardening

Locks down the Proxmox web UI behind a hardened front door — reverse proxy with HTTPS, MFA, audit logging, and fail2ban — the fix for a data-center default install with nothing standing guard.

Most Proxmox installs arrive from the data center or hosting provider with the web UI reachable directly, no multi-factor authentication, and the enterprise-repo nag left unresolved. We put a reverse proxy (Caddy or Nginx) in front of the Proxmox web interface with a real HTTPS certificate, enable MFA via Yubikey or a TOTP app, configure audit-log retention so admin actions are traceable, switch the box to the no-subscription repository if you're not paying for enterprise support, clean up role-based access so accounts only hold the permissions they need, and install fail2ban against repeated login attempts. The result is a hardened administrative front door rather than the box being left exactly as delivered. This is a configuration pass on an existing Proxmox install, not a fresh deployment — if Proxmox itself still needs installing, that's scoped separately. Staff who carry out this pass build the same hardening sequence across multiple clusters, so it's well-trodden rather than assembled ad hoc.

FAQ

How fast is delivery?
Standard delivery is within 20 weekday hours (≈ 2 working days). Express delivery — within 12 weekday hours — costs 25% more.
Does this include installing Proxmox itself?
No — this is a hardening pass on an existing install. A fresh Proxmox deployment is scoped and quoted separately.
Why harden the admin UI if there is nothing sensitive on the box yet?
Because as soon as VMs go live, an unauthenticated, internet-reachable web UI is the highest-value target on the box. Closing it before anything sensitive lands is cheaper than doing it after.
Does this pair with anything else?
It sells well alongside The Proxmox Audit & Tune-up, and as a follow-on once a cluster is freshly built.
