Integration Flexibility and Developer OptionsIntegration Flexibility and Developer OptionsInterFAX supports both REST and SOAP APIs, providing businesses with greater flexibility to integrate fax functionalities into a wide range of systems including both legacy and modern infrastructures. eFax, however, only offers a RESTful API, limiting compatibility with older systems and businesses requiring advanced customizations. |
|
|
Customizable Pricing OptionsCustomizable Pricing OptionsInterFAX provides pre-paid plans where unused credits never expire, making it ideal for businesses with fluctuating faxing needs. eFax follows a subscription-based pricing model, which offers less flexibility and contributes to budget waste, especially for businesses with inconsistent faxing volumes. |
|
|
Healthcare-Focused IntegrationHealthcare-Focused IntegrationInterFAX integrates seamlessly with Electronic Medical Records (EMR) systems such as Epic and OncoEMR, ensuring compliance with HIPAA. It provides features such as secure audit trails and the ability to delete faxes after completion, making it a top choice for healthcare providers. eFax lacks the depth of healthcare-specific integrations and features offered by InterFAX. |
|
|
Security and Data ProtectionSecurity and Data ProtectionInterFAX offers advanced security features, including public/private key authentication and TLS encryption for both inbound and outbound faxes. Its “Delete Fax After Completion” feature ensures that sensitive data is not retained unnecessarily. eFax provides encryption (AES 256-bit) and HITRUST certification, but it lacks granular controls and advanced options for managing sensitive data. |
|
|
High-Volume BroadcastingHigh-Volume BroadcastingInterFAX supports high-volume faxing to as many as 20,000 recipients, making it suitable for large-scale campaigns or businesses that rely on mass communication. eFax only supports fax broadcasting to a limited number of recipients (up to 20 per fax), which is insufficient for high-volume users. |
|
|
Industry-Specific CustomizationIndustry-Specific CustomizationInterFAX offers tailored solutions for industries such as healthcare, finance, and legal, leveraging its advanced API and integration capabilities to address specific needs. eFax is more generic in its approach, offering fewer customization options for niche industries or specialized workflows. |

Questions to ask
Questions to ask
-
Security is a no brainer, and everyone provides it. But you should seek out a cloud fax provider that delivers various data security guardrails to ensure you’re fully covered.
InterFAX is fully compliant with HIPAA, GDPR, and other global data privacy standards, ensuring secure document transmission and storage. It offers end-to-end encryption, audit trails, “Delete after fax” functionality, and customizable security settings to meet industry-specific compliance needs.
eFax, while secure, does not provide the same level of compliance flexibility or customizable security options, making InterFAX the preferred eFAX alternative for highly regulated industries like healthcare, finance, and legal services.
-
Traditional cloud faxing solutions only deliver documents, but AI-powered cloud faxing turns faxed documents into actionable data. With automatic data capture, verification, and routing, InterFAX+AI eliminates manual processing, reducing errors, delays, and inefficiencies. Critical information such as invoices, purchase orders, or patient records get where they need to go, without manual intervention.
eFax does not offer built-in AI capabilities, which means businesses must rely on manual data entry or third-party tools for document processing. InterFAX provides the whole package, and a smarter, more efficient approach to fax management.
-
When it comes to technology, you need a solution that grows alongside your business, and cloud fax is no different. InterFAX is built for scalability, handling high-volume faxing with superior performance and reliability. Its cloud-based architecture supports bulk faxing, automated workflows, and API integrations for seamless business operations.
eFax, while capable of handling faxes, often lacks the advanced automation and scalability needed for enterprise-level document processing. Businesses needing high-capacity, automated fax workflows will find the winner of InterFAX vs eFAX to be InterFAX, as it’s a more robust and flexible solution.
-
Fax definitely isn’t dead, and for many organizations across industries, cloud fax is the trusted technology to safely transmit data across the globe—not email. That means an investment in the right cloud fax provider is an investment in your future growth.
But in terms of daily spend, InterFAX helps businesses reduce costs by eliminating manual processes, improving accuracy, and integrating directly with business systems to save time and resources. Additionally, our flexible pricing model ensures businesses only pay for what they use, avoiding unnecessary overhead.
eFax, while convenient for basic faxing, comes with hidden fees and inflexible pricing plans, making it less cost-efficient for businesses that need scalable, automated, and AI-powered faxing solutions, making InterFAX the best eFAX alternative.
