Zero Exposed Ports: How Our AI Agents Stay Invisible

SecurityTailscaleZero Trust

The Problem with AI Agents on the Internet

Most AI agent setups have a security problem: they need open ports. Webhook URLs, API endpoints, dashboard access — all reachable from the internet.

That's a nightmare.

We use Tailscale — an encrypted mesh network built on WireGuard. That means:

Zero open ports — not a single port is reachable from the internet

Automatic encryption — everything is end-to-end encrypted

No central server — peer-to-peer connections

Simple as WiFi — no complicated VPN setup

Our agents run on a Hetzner server. The firewall allows exactly ONE incoming port: SSH (and even that's secured with key auth).

All agent connections go through Tailscale. Whether we access from laptop, phone, or another server — everything goes through the encrypted mesh.

If you're running AI agents with access to your emails, code, and business data — you do NOT want the world to know about it.

In our playbook, we show step by step how to build the same setup.

And of course, the guide is available in German. 🇩🇪
