The Complete Self-Hosting Security Stack: Fail2Ban + CrowdSec + Authelia Running self-hosted services on the open internet without a security stack is like leaving your front door unlocked in a busy neighborhood. Individual tools help, but real protection comes from layering defenses so each one covers the gaps of the others. This guide builds a complete security stack using three open-source tools: Fail2Ban — reactive log-based banning for brute-force attacks CrowdSec — community-powered threat intelligence and behavioral detection Authelia — authentication portal with single sign-on and multi-factor authentication Together, they give you intrusion prevention, shared threat intelligence, and access control. All running in Docker, all free. ...

The Complete Self-Hosting Security Stack: Fail2Ban + CrowdSec + Authelia Running self-hosted services is great — until someone else discovers them. The moment you expose a port to the internet, bots start probing. Brute-force SSH attempts, credential stuffing on web apps, vulnerability scanners — it never stops. No single tool solves this. You need layers. This guide walks through building a complete security stack using three open-source tools that complement each other perfectly: ...

Running Authentik vs Authelia: SSO Comparison for Self-Hosters (2026) You’re tired of logging into every self-hosted service separately. You want single sign-on. You’ve narrowed it down to two options: Authentik and Authelia. Both are open-source, both work with Docker, both solve the “too many logins” problem — but they take fundamentally different approaches. Authentik is a full identity provider. Authelia is a lightweight authentication portal. Choosing between them depends on what you actually need. ...

If you’re running multiple self-hosted services, you’ve probably noticed the login fatigue. Nextcloud has its own login. Portainer has another. Grafana, Gitea, Jellyfin — each with separate credentials. It’s a mess. Authelia solves this by acting as a single sign-on (SSO) gateway with built-in two-factor authentication (2FA). Put it in front of your reverse proxy and every service gets enterprise-grade authentication without touching the service itself. What is Authelia? Authelia is an open-source authentication and authorization server. It works as a companion to your reverse proxy (Nginx Proxy Manager, Traefik, Caddy) and provides: ...
