SOLUTION COMPARISON

InterFAX vs ETHERFAX

When comparing vendors such as InterFAX vs ETHERFAX, the products may look similar at a quick glance, but once you dive into the features and benefits, InterFAX is the clear ETHERFAX alternative.

InterFAX delivers secure, reliable, and compliant cloud fax service that integrates seamlessly into existing workflows, systems, and applications, reduces manual data entry, and scales to meet your growing needs, all while ensuring data security. ETHERFAX covers some of that but isn’t a fully comprehensive solution.

For businesses prioritizing flexibility, security, advanced APIs, end-to-end security, compliance, and high-volume efficiency, InterFAX is a simple choice.

	Comparison Comparison
	Compliance and Security Compliance and Security Both are certified for PCI DSS Level 1 for both inbound and outbound faxing, but InterFAX offers a hardened subsystem specifically for handling secure fax data, something ETHERFAX does not clearly match. InterFAX also provides clear options for “delete upon delivery,” full audit trails, and in-country data residency (e.g., for PHIPA in Canada), with certifications such as ISO 27001 and HIPAA fully documented and in place. While ETHERFAX has strong general security, some compliance items like FedRAMP High are still awaiting authorization, and specific deletion or data residency policies aren’t clearly defined. For organizations requiring high assurance, immediate certification, and granular control, InterFAX delivers a more mature and transparent compliance posture, making it an ideal ETHERFAX alternative.
	Mature Integrations Mature Integrations InterFAX offers a broader range of prebuilt connections with major business and healthcare platforms like Salesforce, Epic, and RamSoft’s PowerServer. It also offers seamless multifunction printer (MFP) integration through a partnership with Konica Minolta, enabling direct faxing from devices without traditional fax servers. InterFAX supports multiple user workflows, including email, web portals, and APIs—making it highly flexible and easy to embed into existing systems. While ETHERFAX has solid developer tools and some integrations, InterFAX provides a more mature, enterprise-ready integration ecosystem tailored to diverse business and healthcare environments.
	High Volume Workflow Optimization High Volume Workflow Optimization InterFAX offers high-volume workflow optimization due to its robust support for large-scale fax broadcasting (up to 20,000 recipients), unlimited senders, and scalable cloud infrastructure, eliminating bottlenecks. It offers advanced automation tools like intelligent capture to reduce manual processing, and flexible APIs to integrate with existing systems. Features such as deferred transmission and automatic retries ensure efficient delivery. InterFAX provides detailed reporting and monitoring to manage high volumes effectively. While ETHERFAX supports scalable faxing and peak overflow handling, InterFAX offers a more comprehensive and mature solution for organizations with demanding, high-volume fax workflows.
	Cloud vs. Hybrid Fax Cloud vs. Hybrid Fax InterFAX is the superior ETHERFAX alternative due to its fully cloud-native model, which eliminates the need for on-premises fax servers, phone lines, or hardware maintenance. This results in faster deployment, easier scalability, lower infrastructure costs, and greater reliability through built-in redundancy and high availability. InterFAX also provides consistent security controls across the entire system, simplified remote access for users, and strong migration support for porting existing fax numbers.
	Scalability Scalability InterFAX easily manages high-volume fax, supporting up to 20,000 faxes per batch, making it ideal for both growing businesses and enterprises with large-scale communication needs. ETHERFAX’s services are scalable when replacing legacy, on-premise faxing infrastructure. However, its hybrid architecture is better suited for certain environments and may not offer the same “cloud-native” scalability as InterFAX. When comparing InterFAX vs ETHERFAX, the latter is unable to deliver on cloud scalability for businesses with significant faxing needs.
	Customer Support Customer Support InterFAX boasts a higher level of customer service than ETHERFAX by offering more comprehensive 24/7 global support, more localized phone and email help, strong migration and onboarding assistance, faster responses, friendlier personnel, and better documentation resources. While ETHERFAX is praised for its responsive support in standard business hours and reliability, it has limitations in its administrative portal, and does not match InterFAX’s support SLAs or global reach under its standard plan. If your organization needs always‑on support, fast escalation, and minimal friction for onboarding or migration, InterFAX stands out as the preferred solution.
	Pricing Flexibility Pricing Flexibility InterFAX offers superior pricing flexibility by providing clear, transparent, and scalable plans without setup fees or long-term contracts. InterFAX allows businesses to choose from tiered subscription options or customized enterprise solutions, with straightforward overage charges and flexible billing methods like prepaid or ongoing credit billing. In contrast, ETHERFAX’s pricing is less transparent, and lacks clarity around overage fees and potential extra costs related to its hybrid-cloud model and on-premises infrastructure, making budgeting more complex. Overall, InterFAX’s flexible and predictable pricing better supports a wide range of business needs.
	Mobile Access Mobile Access InterFAX offers advanced mobile access compared to ETHERFAX by providing a secure, web-based control panel accessible from any device. It also seamlessly integrates with Konica Minolta, enabling users to send and receive faxes efficiently from anywhere. While ETHERFAX offers a mobile app and email-to-fax options for mobile faxing, InterFAX’s broader device compatibility and deeper integrations deliver a more flexible, reliable, and consistent mobile faxing experience for businesses.

Changed the Way We Work for the Better

I really like this tool mainly because of the ease of sending faxes and because the APIs are easy to use and I also liked the experience with the support which is friendly and excellent. On the other hand, the interface is well done, a little minimalist but excellent, which makes it easy to use so we do not get confused in each of its functions.

Mid-Market

Good Interface

What I like most about Upland InterFAX is the technical support is friendly, provides quick responses and always solves the problem. I also like that I can sed and receive faxes without any problems. Also, during the time Ive been using it Ive liked the improved user interface and that the drag and drop feature has been very useful.

Faxing in the Modern Day

This service is great for those that no longer want the extra steps of having an analog phone line and physical fax machine. For the random times you need to a fax line it's a great alternative. This will work regardless of where you are or what you are doing and sending/receiving faxes through your email client is a breeze. It has a decent GUI interface and it does a good job of separating incoming and outgoing faxes. There is a history section that shows what has come in and gone out which is nice keeping everything in pdf.

Enterprise

Very Convenient Service

Interfax is my go-to method of faxing from my desk. All I have to do is scan my document or attach an already digital pdf copy and send it through email. I have an easy record to reference when I need to find out when I faxed something as well, just a quick search in gmail.

Easy Access Tool

I like this tool because it is easy to use due to its user interface and a good easy to configure panel. I also like being able to review the reports with their drag and drop features and the support responds quickly to our questions. This online fax tool works very well overall. Its integration was perfect, it solved our problems with Online Fax, improving the workflow. Sending things by fax physically is no longer a problem, now everything is online and we save time and money.
