Is Online Faxing Secure?

Graphic image representing security and technology

One of the primary concerns businesses face when considering web-based faxing is security. On the surface, a faxing system that makes use of an internet connection seems to be less secure than the traditional fax. But in reality, online faxing can be one of the safest faxing methods available. While a conventional faxing system prints physical copies easily readable by anyone with access to the fax machine, internet fax systems deliver faxes to an inbox, where it’s less likely to be accessed.

However, this assumes the faxing service provider has taken the proper precautions, like SSL encryption and multi-step authentication. Not all online fax services employ these methods, so it’s important to know what to look for when shopping for an online faxing service. For this reason, Softlinx has assembled some of the most critical security issues to consider when comparing possible web-based faxing services.

How to Assess Fax Security

When you want to choose an online faxing service to work with, keep your security needs in mind. While a company that offers no-equipment, user-friendly faxing at a cheap rate may sound desirable, obtaining appropriate security for your business is essential. Here are some primary topics to look out for and ask about:

  • Password Protection: Ensuring your faxes are only available to be viewed by you, the recipients and your staff is a fundamental security need. Multi-factor authentication helps protect your faxing system at a fundamental level, so outside parties don’t have access to your faxing platform or your fax history.
  • Virus Scanning: Incoming faxes sent online can carry viruses with them, just like emails, so it’s essential for a faxing service to screen them before you open them.
  • File Encryption: Encryption adds an extra layer of protection to a faxed message, as it is digitally transmitted or uploaded to a fax server. This way, your data is still protected even if it’s intercepted.
  • SSL Certificate:Web-based fax platforms use SSL certificates to create secure, protected connections in a customer’s browser, so any data you input into the browser is protected. You know the browser connection is secure when you see a little icon of a lock next to the URL in your browser.
  • Standard Compliance: Depending on the type of business you run, you may be required to uphold specific security and privacy standards, as dictated by your industry or government. HIPAA and PCI-DSS are the two most common examples, with HIPAA protecting the personal health information of patients and PCI-DSS protecting the financial information of customers. Both standards require a certain amount of security in your faxing protocol and data center hosting, and any fax service that meets these requirements will say they are HIPAA and PCI-DSS compliant.

Other features to look out for include system logs, user tracking, and network management, all of which can contribute to a highly secure fax system.
