FaxZero vs Retarus

Read on for our full Retarus vs FaxZero comparison.


Retarus is an enterprise solution that implements robust security protocols like HTTPS transfers, virtual private network (VPN), and encrypted TLS connections. It also has a secure encrypted storage system, the Retarus Enterprise Cloud, where your faxes are stored. You can also request all incoming faxes to be encrypted. Furthermore, it uses NeverBusy Technology and multiple storage centers to prevent downtime and ensure maximum availability through redundant backups. 

In comparison, FaxZero looks like a poor alternative to Retarus because of its simplicity. You might even wonder if it can send secure faxes since it’s made for one-time faxing only. According to its website, FaxZero uses HTTPS protocol to encrypt processed and transmitted information. The service also keeps the provided information private and deletes faxes within three days of successful transmission. It also performs periodic updates to its security features.

User Experience

Retarus, as an enterprise solution, offers Cloud Fax as one of its products. Despite being a robust enterprise app, it has a modern interface that’s easy to set up and navigate. 

As a Retarus alternative, the FaxZero interface has a very basic and somewhat dated design. It offers limited options for fax sending. On a positive note, you don’t need to spend hours to figure out how it works. 

FaxZero vs Retarus

HIPAA Compliance

It’s not surprising that FaxZero is not HIPAA compliant. For starters, it is not intended to be one, and while it secures transmitted faxes, there are other factors to consider to make this fax service abide by the HIPAA regulations

Retarus makes a better FaxZero alternative if HIPAA compliance is what you want. It implements the best security and privacy protocols to protect confidential patient information. Plus, it’s ready to provide a Business Associate Agreement (BAA) should you request one.


Retarus has digital signing capability through its integration with third-party digital signature apps. FaxZero lacks this capability.

Fax Numbers and Receiving Faxes 

FaxZero doesn’t offer any local or toll-free fax numbers, nor does it allow the receiving of faxes. You can only use this service to send faxes.

Retarus, on the other hand, allows you to receive faxes from anywhere in the world with its local numbers. It also supports porting existing numbers, so you don’t have to start all over with a new one.

Fax Status Monitoring

FaxZero will inform you through email of the status of your transmitted faxes, whether it’s a successful or failed delivery. However, you must see to it to check your SPAM folder and add its email address to your safelist, as most email clients flag its email address as spam. This can cause you to miss out on critical fax status updates.

Retarus offers comprehensive fax status reporting with real-time updates. It will immediately notify you of each successful fax delivery, so you don’t have to waste time checking them manually.

Pricing and Plans

FaxZero lets you send five faxes for free daily. Each fax can have a maximum of 3 pages, including the cover, but be mindful that it comes with branding. To remove the FaxZero branding, you can pay $2.09 per fax. This is good for 25 pages, including the cover page. Since you’re spending on a per-fax basis, there’s no limit to the number of paid faxes you can send daily.

Retarus doesn’t have a subscription plan or a one-time plan. Its pricing will be based on your specific requirements, so you must contact its sales team to request a quote.

Comparing FaxZero vs Retarus

Comparing Retarus and FaxZero is like comparing two drastically different business solutions. FaxZero is ideal for professionals or anyone needing a convenient and free fax service that they can use on the fly. Therefore, its benefits will have little appeal to those looking to fax regularly and in high volumes.

Retarus, on the other hand, is suitable for anyone needing an enterprise-level cloud-based fax solution. It also appeals to those who want to enable HIPAA-compliant faxing for their business or organization. 

Ultimately, choosing between the two fax services will depend on how often you fax, the number of pages you need to fax, and the features you need to achieve your desired communication outcomes.
