Sfax is a renowned internet fax service offered by a company called Scrypt Inc. The company boasts on having tens of thousands of customers of all sizes. Sfax is useful for both small companies and large corporations.

This internet service is one of the most secure ones in the industry. The service is HIPAA (Health Insurance portability and Accountability Act) compliant and uses solid encryption and security measures, such as 256-bit encryption for all faxes and two-factor authentication.

What is the pricing of Sfax?

Sfax has four plans: Standard, Plus, Contender and Enterprise. All these plans come with two options in terms of billing: monthly billing or annual billing. The latter is of course more affordable.

Here are the four plans and what they include:


Monthly billing - $29/month

Annual billing - $27/month

It includes 350 total fax pages per month, cloud storage for your faxes for an entire year, unlimited users and a toll-free number.

If you exceed your monthly limit, you have to pay $0.10 per additional page.


Monthly billing - $49/month

Annual billing - $47/month

It includes 700 fax pages and the same benefits as the Standard plan.

If you exceed your monthly limit, you have to pay $0.10 per additional page.


Monthly billing - $99/month

Annual billing - $90/month

In addition to the benefits included with Standard and Plus, it also includes the download feature and API.

If you exceed your monthly limit, you have to pay $0.10 per additional page.


This plan does not display fixed quotes because you get a custom price, depending on your needs. You have to contact Sfax for more details and they will make an offer tailored to your needs. Unlike the other three, this plan comes with custom overages.

What are the features and benefits of Sfax?

As we’ve already mentioned it, one of the biggest strengths of Sfax is the fact that it is a very secure and private service. This company places a lot of importance on making their customers feel safe using their service. Sfax comes with:

  • flawless data center and system security
  • it uses full 256-bit TLS encryption and 2048-bit private keys for all documents and data in motion
  • data is protected at rest with 256-bit AES encryption
  • automated session time-outs
  • two-factor authentication

Other features included:

  • this online fax service offers annotations and digital signature
  • fax API that lets you create your own custom integrations
  • print to fax (available on Windows and macOS devices)
  • Support for Word, Excel, PowerPoint, as well as comparable OpenDocument file formats and Rich Text Format. Image files supported include JPEG, PNG, BMP, GIF and TIF. It comes along with normally supported TXT and PDF

  • The ability to download all your faxes with the download service option (however, this option is only available with the most expensive plans: Contender and Enterprise)

Another useful feature of this internet fax service is its mobile app, although there is a drawback here: the app is only available for iOS devices. The mobile app lets you compose faxes with image capture, you can reply to a fax, you can forward a fax, access your files from the document management system and more.

Why should you switch from traditional faxing to internet faxing?

Regardless of the service you want to opt for, you should be aware of the benefits of using internet faxing over traditional, telephone-based one. There are several advantages online faxing has over the conventional one:

  • It is more affordable and helps you cut your expenses; you don’t need to buy fax machines, paper and other consumables such as ink, toners, etc. You don’t have to pay a professional to install the system either, you can do it by yourself
  • It is less harmful for the environment because it is a paperless technology so fewer trees will have to be sacrificed for paper production
  • It is more versatile, flexible and easier to use. Sending an internet fax is similar to sending an e-mail and you can use online fax services from anywhere in the world as long as you have an account with an online fax service and an internet connection at your disposal
  • You can port your phone number
  • Most online fax services also offer mobile apps
  • You get to save space with internet faxing because you no longer need to store bulky fax machines in your office
