Is Faxing Secure? Yes, With the Right Network Protection
When done right, faxing is a very secure means of communication. Lawyers and doctors continue to use faxing — and it’s not because they are lax about document security. Most companies still using fax do so because it meets strict compliance requirements in industries like healthcare and finance, where secure document transmission is critical. Modern cloud-based fax services enhance security by using encryption, secure data centers, and audit trails to protect sensitive information and ensure compliance. So yes, fax is secure, that’s the short answer. Like any other communication channel, fax is as secure as the network it’s running on. If you use a business phone service that includes fax, then you don’t have to worry about securing the infrastructure — but you still have to enforce strong passwords, enable MFA, delete old user accounts, and so on. Let’s go through everything in detail. 1 RingCentral RingEx Employees per Company Size Micro (0-49), Small (50-249), Medium (250-999), Large (1,000-4,999), Enterprise (5,000+) Medium (250-999 Employees), Large (1,000-4,999 Employees), Enterprise (5,000+ Employees) Medium, Large, Enterprise Features Hosted PBX, Managed PBX, Remote User Ability, and more 2 Talkroute Employees per Company Size Micro (0-49), Small (50-249), Medium (250-999), Large (1,000-4,999), Enterprise (5,000+) Any Company Size Any Company Size Features Call Management/Monitoring, Call Routing, Mobile Capabilities, and more Is faxing safe for sensitive information? Yes. It’s perfectly legal and secure to fax a check, a lease, or any other document. As a direct means of point-to-point transmission, fax machines can successfully send sensitive data without exposing it to third parties during transit. In fact, faxed documents are considered legally binding and are included among the approved communication methods regulated in the Health Insurance Portability and Accountability Act (HIPAA) of 1996 — which governs the privacy and security of protected health information (PHI). Whether offline or over the internet, any establishment that faxes confidential information about your health is legally required to enact strict procedures and processes to maintain your privacy. In short, providers must take all necessary steps to control who has access to your data and how it is communicated, including asking for your permission. As a result, only authorized individuals should be able to access and fax your records. Administrative personnel are also advised to take extreme caution when it comes to ensuring that your fax number is accurate, reconfirming receipt immediately after sending. Such measures protect not only your confidential data but also the business itself from hefty fines. Most online business fax solutions include modern security measures to protect your sensitive data. These hosted services often encrypt your fax transmissions and store your data using Transport Layer Security (TLS), establishing a unique “handshake” between two user ports to guarantee a safe connection. During transmission, AES (Advanced Encryption Standard) 256-bit encryption ensures that all data is kept secure and inaccessible to cyberattacks. This security protocol uses a symmetrical algorithm and a 256-bit key to transform your data into a code that is undecipherable to humans and computers alike.

Anytime you send a fax, whether analog or digital, there are opportunities for data interception or infiltration that can present a dangerous security breach. Because traditional fax machines are not connected to an office’s online network, they are not “hackable” in the same way that an online file might be. Although a landline can potentially be hacked via wiretapping, most cyber attackers are searching out weak spots in your digital framework. The real vulnerability of analog faxing lies in its points of origin and receipt. For example, many fax machines store unencrypted electronic copies of each transmission on their hard drives. In some cases, these copies will get backed up to a company’s shared fax server, creating the potential for online interception. Other problem areas include the human errors of misdialing a recipient’s fax number or leaving an incoming fax sitting in the machine’s tray for any amount of time. Your method of storing or shredding any fax printouts also deserves careful consideration, as any missteps can lead to an unauthorized person obtaining sensitive data. As for the role of telephone companies, they are required by the Federal Communications Commission (FCC) to secure records regarding your billing information and service usage. They are not, however, generally held responsible for any breaches in your fax line or protocols. Similarly, the FCC demands that internet providers protect personal customer records and clearly communicate relevant network management protocols. Such features often include the most recent iteration of Wi-Fi Protected Access (WPA) encryption to keep your data safe from prying eyes. Nevertheless, an attacker may still hack your information by getting ahold of your password or running a phishing scam to access any faxes stored on your company’s server. Once again, your provider is not typically considered at fault for these breaches. Keeping your fax system truly secure means taking extra precautions to make sure your data ends up in the right hands. The best practices for supporting a safe transmission include: Setting access codes for any personnel who might use the machine. Calling beforehand to confirm that your recipient is standing by to retrieve the document. Securing the machine hard drive to ensure that all information stored on a shared server is encrypted and purged at regular intervals. Following any additional protocols when sending sensitive data, such as including a HIPAA-compliant cover sheet. Using only dedicated machines located in a secure area of your office space rather than a public device. The last thing I’ll say is — and this is true of any tech, not just faxing — is that it’s essential to have Multi-Factor Authentication enabled on any account that has access to sensitive information. MFA is an easy and effective way to prevent phishing attacks. Is faxing secure from a public fax machine?
