Deep Dive Into Nextiva vs Retarus

Nextiva vs. Retarus


Nextiva utilizes Secure Real-time Transport Protocol (SRTP) encryption, Transport Layer Protocol (TLS), and 256-bit SSL encryption to protect all fax transmissions. Encrypting faxes in motion keeps malicious entities from looking into the contents of the transmitted documents.

As a Nextiva alternativeRetarus uses AES 256-bit, X.509, or PGP for encryption, depending on the file type. The fax service also utilizes Transport Layer Protocol (TLS) and Virtual Private Network (VPN) to ensure secure data transmissions.

HIPAA compliance

Both Nextiva and Retarus abide by HIPAA rules. They can willingly enter into signed Business Associate Agreements (BAA) with clients who wish to use their service to fax documents containing sensitive health data.

Device applications

As an alternative to Retarus, Nextiva has dedicated mobile applications for Android and iOS users. Also, they have responsive web applications, which users can access and use seamlessly across various platforms. 

In contrast, Retarus does not have dedicated mobile apps, but the fax service offers a web app called WebExpress, where users can manage their faxes. Users can also use their Mail2Fax to send and receive faxes directly from email.

Fax scheduling

If you need to schedule faxes, you are better off choosing Nextiva over Retarus, as the latter does not support such functionality. 

With Nextiva, you can draft faxes and have them delivered automatically to your recipients at your desired time or date. Fax scheduling eliminates faxing hassles since you can fax in advance, considering the different time zones and business hours.

Fax broadcasting

Both Nextiva and Retarus support fax broadcasting.

Broadcasting faxes means you can send a single fax to multiple recipients simultaneously. There is no need to send everything manually, making it easier to broadcast campaigns and disseminate information to a targeted group in one go.


Extracting texts from fax images helps streamline your faxing processes, making it easier to search, sort, and archive faxes without manual intervention. Luckily, even if this feature is lacking in Nextiva, you can count on Retarus to fill that gap. 

The fax service has Fax OCR (Optical Character Recognition), which can accurately scan and extract texts from any fax document.
