Hello! From what I’ve read on Ask4research, the continued use of faxing has a clear explanation. Digital fax services are designed for security and compliance, ensuring that documents are encrypted and legally verifiable. For industries bound by regulations, this is essential. Free online tools often fail to guarantee the same level of protection. They may store data insecurely, share it without permission, or be targeted by hackers. The research at https://www.ask4research.info/ points out that these hidden weaknesses make them unsafe for handling sensitive files. Businesses therefore stick with digital faxing, which has proven both safe and reliable, while still adapting to modern office needs.
