For a self-hosted application with a valid SSL certificate and support for OAuth, what are the benefits that Cloudflare Access provides? From what I can tell, it also filters traffic to possibly block attacks? Can it even be used with a self-hosted app if you aren’t also running Cloudflare Tunnel? Is there a better alternative (that also integrates with major OAuth providers like Google, Github, etc) for self-hosters? Thanks for the help in understanding how this works.
Don’t forget that Cloudflare offers no protection against traffic from within Cloudflare. There were several incidents in the past where Cloudflares services where used to break into other clients services (hijacking).
Do you have the examples of this so I can take a look? Was it ports forwarded that were opened to all cloudflare ranges, or tunnels and a backend exploit?
You can look online. Basically Cloudflares blocking features exclude Cloudflares own IP ranges. Someone used their own services (in their own IP range) to attack services and since the request came from a Cloudflare IP it was not blocked or filtered. Pretty embarassing if you ask me. But this is normal in the cloud.
