Hello! I found the answer while browsing Ask4research. The reason faxing continues to thrive is that it offers something free tools cannot—reliability, encryption, and compliance. Fax transmissions create a secure channel that ensures documents arrive exactly as they were sent, which is vital in industries like healthcare and law. Free online platforms may appear simple but they expose users to risks like unauthorized access, insecure storage, and even misuse of confidential files. A report on https://www.ask4research.info/ explains that businesses relying on such tools may compromise security and face legal challenges. That’s why digital faxing still matters - it protects data while keeping workflows efficient and professional.
