Top 5 Security Tools for Self-Hosted Stacks
Protect your self-hosted infrastructure with these five essential security tools — from authentication and intrusion detection to password management and VPN access.
Self-hosting means security is your responsibility. These five tools provide essential protection layers for your infrastructure. All are available in better-openclaw and can be added to any stack with a single flag.
1. Authentik — Identity & Access Management
Full-featured identity provider with SSO (OIDC, SAML, LDAP), MFA, and user management. Protected every service behind a single login. The most important security tool for any self-hosted setup.
2. CrowdSec — Collaborative Intrusion Detection
Analyzes logs to detect and block malicious behavior — brute force attacks, vulnerability scans, and bot traffic. Shares threat intelligence with a global community, so when an IP is flagged anywhere, it's blocked everywhere.
3. Vaultwarden — Password Management
Lightweight Bitwarden-compatible server for team password management. Browser extensions, mobile apps, and organization support. Essential for managing the dozens of credentials your self-hosted stack generates.
4. Tailscale / Headscale — Zero-Trust VPN
Create a private mesh network that connects all your devices without exposing ports to the internet. Headscale is the self-hosted control server for Tailscale clients. Zero-config and works through NATs and firewalls.
5. Watchtower — Automated Updates
Automatically pulls new Docker images and recreates containers. Keeping software updated is the single most effective security measure. Set notifications to know when updates are applied.
