eFax Corporate provides industry-grade encryption methods to prevent cyber threats. It uses TLS encryption and 256-bit AES encryption, which provide a strong layer of protection against interception. Moreover, eFax assigns secure IDs and a toll-free or local number for each user. Data is stored in Tier III or Tier IV data centers with 24/7 monitoring.
Sfax provides the same encryption methods. As an added form of security, it doesn’t allow single sign-on (SSO). Instead, it offers multiple users per fax line. Data is also stored on your Sfax account, which uses SSAE16 Type II certified Tier III or IV data centers.
SSAE16 is a set of auditing standards and guidance for service organizations established by the American Institute of Certified Public Accountants (AICPA). It’s important to note that in May 2017, SSAE 16 was superseded by SSAE 18, which included notable improvements.
eFax Corporate and Sfax are internet service providers that help you comply with the Health Insurance Portability and Accountability Act (HIPAA). Compliance with HIPAA means you must employ technical standards, such as encrypted communications, to ensure the privacy and safety of protected health information (PHI).
Both fax services are willing to sign a Business Associate Agreement (BAA), which would make them accountable for any PHI mishandling. Note that you need to get the proper plan to ensure HIPAA compliance. For eFax, you must avail of its eFax Corporate Plan with BAA. For Sfax, you can get any plan higher than the Standard plan.
Sfax doesn’t allow faxing via email because of security concerns. You can only send a fax using your sFax account. If you’re looking for an alternative to Sfax that allows email to fax, eFax Corporate can be a good choice. It lets you fax from Gmail, Outlook, Yahoo, and other standard email clients.
To secure fax by email transmissions, eFax Corporate uses eFax Secure. eFax Secure emails your faxes using TLS 1.2 encryption to protect them during transit. Meanwhile, faxes received arrive with a URL to a secure website. This URL directs you to your eFax Corporate account so you can view the fax securely.
eFax Corporate allows faxing through its free Android or iOS apps. This helps you eliminate the sluggishness in traditional faxing by turning your mobile device into a virtual fax machine.
Sfax, on the other hand, limits mobile faxing to iOS and through your web browser. Also, its iOS app lets you monitor fax activity and securely manage your faxes from anywhere. However, it’s crucial to note that the Sfax app’s last update was in January 2022. The lack of newer updates could pose serious security risks and compatibility issues.
eFax and Sfax have eSignature features, so you can sign your faxes without printing them. You can digitally sign documents using eFax in two ways: using your finger to write on a touchscreen or choosing from your saved signatures. Sfax lets you drag and drop your signature into your document.
Both Sfax and the eFax Corporate plan include API and developer support. These fax services also employ APIs based on the RESTful standard, which lets you create user-friendly systems across different devices and platforms. You can make your fax workflows more efficient with APIs. Configuring APIs lets you fax directly using your current DMS or EHR system.
eFax Corporate lets you port your existing fax number to their service. Alternatively, you can choose from local or toll-free numbers. Toll-free numbers are easier to remember, but local numbers help establish credibility.
Sfax also offers number porting services. Also, you must pay a $10 one-time fee for each ported fax line.
eFax Corporate’s pricing focuses on customizable solutions, so the total cost depends on your specific faxing needs and compliance requirements.
Sfax, on the other hand, follows a subscription-based pricing model. Its lowest plan starts at $29 per month. If you’re doing high-volume faxing regularly, consider paying for its Enterprise plan with customized pricing.
Sfax and eFax are HIPAA-compliant internet fax services that take data security and privacy seriously. However, eFax Corporate offers more faxing features, such as cloud storage integrations, email-to-fax, and local numbers. Also, it doesn’t limit faxing to certain countries or regions.
As for Sfax, it’s a noteworthy option, especially if you want to ensure compliance with various industry regulations. The fax service provides a complete audit trail of all faxes sent and received.
