Security Built for Online Faxing
Best Fax uses TLS encryption in transit and stores documents in access-controlled accounts. The final delivery leg uses the recipient's phone line.
Quick Answer
Best Fax uses TLS encryption in transit and stores documents in access-controlled accounts. The final delivery leg travels over the recipient's phone line. Unlike traditional faxes that may print in open areas, online faxes arrive in a dashboard protected by per-user access controls.
Key Features
TLS Encryption in Transit
TLS encryption protects documents in transit between your device and Best Fax. The final delivery leg travels over the recipient's phone line, as with any fax transmission.
Security-Minded Workflows
TLS encryption in transit, per-user access controls, and delivery confirmation support careful document handling. Best Fax does not offer a BAA.
Automatic Document Deletion
After successful delivery, temporary processing copies are automatically removed from our servers. Your fax history and delivery records remain accessible in your dashboard.
Secure Access Controls
Role-based team accounts ensure only authorized people can send and view faxes. Sub-user permissions let you control exactly who can do what.
Delivery Confirmation
Verified delivery receipts confirm that your document reached the intended fax machine — not just the network. You know exactly when delivery occurred.
No Third-Party Access
Best Fax does not share, sell, or provide access to your documents to any third party. Your files are processed solely for transmission purposes.
How Best Fax Protects Your Documents
Security at Best Fax operates at every layer. When you upload a document, it's encrypted in transit using TLS — the same protocol that protects online banking. On our servers, access to your documents is restricted to your account only. During fax transmission, the document is sent over the phone network to the recipient's machine. After successful delivery, documents are removed from temporary processing storage. Your complete fax history remains in your access-controlled dashboard for your records.
Online Faxing Compared with Traditional Fax
Traditional fax machines can print documents in open areas where anyone walking by can read them. Best Fax instead places incoming faxes in an access-controlled dashboard. TLS protects documents in transit between your device and Best Fax, while the final delivery leg travels over the recipient's phone line. Login credentials and role-based permissions control dashboard access.
Security for Sensitive Industries
Best Fax is designed for organizations that handle sensitive information. Our security measures — TLS encryption, per-user access controls, delivery confirmation, and transmission records — are relevant to healthcare providers, legal professionals, and financial services. For healthcare-specific compliance considerations, see our healthcare faxing page. Payments are processed securely through Stripe, which maintains PCI-DSS compliance.
Security for Teams and Organizations
For businesses with multiple users, Best Fax provides granular access controls. Account administrators can create sub-user accounts with specific permissions — controlling who can send faxes, who can view received faxes, and who can access the full fax history. This prevents unauthorized access within your organization while giving each team member the access they need to do their job. All user actions are logged for audit purposes.
Frequently Asked Questions
