Is fax still considered a secure way to send sensitive documents, or has it been overtaken by digital alternatives? I've read that traditional fax isn't encrypted, but online fax services use TLS – though they might introduce other risks like email or cloud storage vulnerabilities.

I work in healthcare and we still use fax because many institutions refuse to accept documents any other way. The reality is that traditional phone-line fax is not encrypted, but it is a closed system that does not go through the internet, so it is less exposed to mass hacking attempts. Online faxing adds TLS encryption during transmission, which is a layer of protection that analog fax does not have. But it also introduces risks like email compromise, cloud storage breaches, or weak account passwords. I spent time reading through https://mfax.to/blog/is-fax-secure to understand the trade-offs, and it helped me realize that no method is perfect. The key is choosing a service that secures both transmission and storage, with features like audit logs, access controls, and encryption at rest. For sensitive documents, I now use a HIPAA-compliant online service because it gives me more control and visibility than an old machine sitting in a hallway. The extra steps are worth it for peace of mind.
