Deep Dive Into SRFax vs. Nextiva

Nextiva vs SRFax

Security and HIPAA Compliance

SRFax assures HIPAA compliance through a BAA, securing patient data with SSL encryption, firewalls, and optional PGP encryption. User access is via email and password, preventing unauthorized data access. You can also count on its redundant backup systems and 24/7 server security.

Nextiva, as an SRFax alternative, offers top-tier security with its 256-bit SSL, TLS, and SRTP encryption. Its fortified facilities have security scanners, 24/7 monitoring, and bullet-resistant glass. The service also meets the standards for HIPAA compliance.

Both offer API and Developer Support

SRFax offers a feature-rich RESTful Fax API, which you can use to control how you send or receive faxes in any app or platform. This is a useful feature that enables faxing straight from your EMR and EHR systems.

If you need integrations or APIs, you should get the Nextiva business plans which integrate with various apps like Salesforce, Zoho, Google Workspace, and more. Its dedicated faxing solution, Nextiva vFax, doesn’t offer any integration with other apps.

Fax broadcasting is better with SRFax

SRFax enables fax broadcasting, which you can tailor to your specific needs. You can add or remove recipients as required and integrate SRFax with your business applications like CRM systems. With fax broadcasting, you can fax simultaneously to a maximum of 50 fax numbers.

As an alternative to SRFax, Nextiva lets you send up to 6 faxes at once. To send additional faxes, you need to wait for these faxes to complete. Technically, this isn’t fax broadcasting, which they don’t currently support. 

Easy team management

Nextiva lets multiple people log in to the vFAX portal at once, so they can share one fax number. However, for each vFax, only one unique email address can be used to send faxes. You can add up to five additional email addresses to receive fax notifications. 

SRFax offers unlimited outbound users free of charge. They can have their own login accounts and won’t be able to view faxes of other users. If you want each user to have a unique fax number, they can with a fee of $4.95 per number.

There’s no extra usage fee for using a toll-free number. 

With SRFax, you get toll-free and local numbers for Canada and the US. You can also port an existing number for a one-time fee of $25. SRFax also supports international faxing with varied rates depending on the country.
