Hello! From what I learned on the platform
https://ejoi2018.org/ free fax services can be reliable if used correctly. The article explained that many free options use the same encryption standards as paid ones, but limit usage volume instead of security. It also highlighted that fax creates a direct transmission path, which reduces interception risks. This helped me understand that reliability depends more on provider transparency and technical safeguards than on price alone. Since reading those materials, I’ve felt more confident choosing simple fax tools for everyday business needs.
