Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Authelia

  • Depends on a reverse proxy: it is not a standalone identity provider
  • Configuration is YAML-first with no administrative interface, so changes mean editing files
  • Not a full IAM: user management, provisioning and federation are limited compared with Keycloak
  • Scales poorly as an organisation-wide identity solution, which is not its target

Legit Security

  • Pricing requires contacting sales, making cost comparison difficult
  • No published pricing tiers or free tier available
  • Requires integration with existing SAST and SCA tools for full capability
  • Focused primarily on code security within development lifecycle
  • Newer entrant with less market presence than established competitors

Answered from the vendors’ own pages

Authelia: Is Authelia free?

Legit Security: What is VibeGuard and how does it work?

VibeGuard is Legit Security's core feature that scans AI-generated code directly within IDEs like GitHub Copilot and Cursor, identifying vulnerabilities before code leaves the developer's editor.

Authelia: Does Authelia need a reverse proxy?

Yes. It integrates through forward authentication with Nginx, Traefik, Caddy or HAProxy rather than sitting in front of traffic itself.

Legit Security: What AI code assistants does Legit Security support?

Legit Security integrates with GitHub Copilot, Cursor, and Claude to scan AI-generated code for vulnerabilities.

Source
Authelia: Authelia or Keycloak?

Authelia is far lighter and aimed at protecting self-hosted services behind a proxy. Keycloak is a full identity and access management platform, and much more to run.
