iFax

Mobile-first HIPAA faxing with built-in eSign

4.5^/5

Editor's score

iFax feels like a real modern SaaS app. The mobile clients are polished. The Plus plan ships a free signed BAA from day one. eSign is built in, not sold as an add-on. For most healthcare practices and small businesses, it strikes the right balance. You get compliance, usability and a fair price without a procurement committee.

eFax

The category-defining brand for large enterprise fax operations

4.4^/5

Editor's score

eFax is the longest-running brand in cloud fax. Its base is enterprise. Customers value continuity and procurement that feels familiar. Three plans cover the catalogue. Plus is for solo senders. Pro suits small teams. Protect at $49.99 a month unlocks HIPAA. The price is high next to modern rivals. Yet it remains the safe-list pick for teams that have used eFax for years.

Dropbox Fax

The HelloFax product, now under the Dropbox brand

4.4^/5

Editor's score

Dropbox Fax is the cloud fax product Dropbox bought as HelloFax in 2015. It now sits inside Dropbox Sign Services alongside Dropbox Sign and Dropbox Forms. Dropbox's Trust Center explicitly covers all three products under one compliance envelope. The web app is clean. The free tier removes friction. Fax numbers cover the US, UK and Canada. Integrations with Drive, Box and OneDrive feel native. HIPAA, HITECH, SOC 2 Type 2, ISO 27001, PCI DSS and GDPR all apply to the fax workflow when the BAA is signed at the Dropbox Sign Business or Premium tier.

SRFax

Healthcare-grade fax across the US and Canada with PHIPA coverage

4.2^/5

Editor's score

SRFax is the quiet workhorse of healthcare fax. US clinics and Canadian law firms reach for it when they need HIPAA or PHIPA at a reasonable price. Healthcare plans start at $12.60 a month for 200 pages. The signed BAA is free. Every plan ships free PGP encryption — rare in this category. The Canadian coverage is better than most US-first rivals.
