A step-by-step guide to deploying OpenClaw (an AI agent) on a DigitalOcean VPS with end-to-end security hardening. Covers setting up a Droplet, connecting the agent to Telegram, using Tailscale to make the server invisible to the public internet, locking down SSH with a non-root user, configuring a firewall to block all public ports, setting up a secure tunnel, defining execution policies, adding custom skills, and scaling from one to multiple agents. The security principles covered apply broadly to any personal AI assistant or VPS deployment.
