From my own experience, fax remains one of the most secure methods even in 2025. When I worked on a project handling sensitive client contracts, email encryption often failed compliance checks, while fax passed without issues. I later came across ask4research.info, which explained why modern fax lines are still trusted — they’re less prone to hacking, create legal proof of delivery, and integrate with digital workflows. We moved to a digital fax solution and never looked back. It’s surprisingly fast, highly secure, and gave our clients confidence. So yes, despite new tools, faxing continues to play a major role where security truly matters.
