I will secure and harden the linux vps your ai agent runs on

Your agent has an API key, a database and a shell. It lives on a VPS that was set up in twenty minutes and never touched again. Port 22 open to the whole internet, root login on, no updates since March.

I close that down.

What I do:

- SSH: keys only, no root login, no password auth, port moved off 22

- Firewall: only what you actually use stays open, everything else shut

- fail2ban on SSH and your web endpoints, so brute force stops being free

- Automatic security updates, so the box doesn't rot between deploys

- A look at what your agent itself exposes: open ports, admin panels, .env sitting in a web root

What you get:

- A before/after list: what was reachable, what is now

- On Standard, Cloudflare in front, with rate limits on login and API

- On Premium, Telegram alerts when something goes wrong at 3am, plus backups

I have run my own servers behind Cloudflare since 2023 and I build security monitoring for a living (secmon.io). Same work, done on your box.

I need root or sudo access, and access to DNS if there is a domain.

Not included: rewriting your app, migrating to another host, compliance paperwork, pentesting a whole company network.
