The short version
- Only Authelia has a free tier, so it costs nothing to try first.
- Each has a real cost: Authelia depends on a reverse proxy: it is not a standalone identity provider; Sophos Intercept X sophos publishes no price for endpoint protection: the product page names editions but gives no per user rate, no minimum seat count and no contract length, and routes buyers to a sales enquiry
- They diverge on capability: Authelia covers Reverse proxy integration, Sophos Intercept X covers Deep learning AI.

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
Sophos Intercept X
- Sophos publishes no price for endpoint protection: the product page names editions but gives no per user rate, no minimum seat count and no contract length, and routes buyers to a sales enquiry
- Extended detection and response requires the Advanced with XDR edition rather than the base endpoint product
- 24x7 monitored detection and response is sold as the separate Sophos MDR service on top of the endpoint licence
- The Intercept X name has been retired in favour of Sophos Endpoint, so older documentation refers to a brand the vendor no longer uses
