eFax and SRFax both sell HIPAA-compliant fax, but to very different buyers. eFax is the brand-recognition incumbent: long-running, enterprise-friendly, and bundled with jSign signatures on the Protect tier at $49.99 per month. SRFax is the quiet specialist: $12.60 per month for Healthcare Lite with 200 HIPAA-compliant pages, free PGP encryption across every plan, and explicit PHIPA coverage for Ontario. The price gap is wide enough that the choice usually comes down to whether the buyer values eFax's legacy footprint or SRFax's compliance-per-dollar ratio.
eFax and SRFax look superficially similar — both ship HIPAA-compliant cloud fax with audit trails, both encrypt PHI in transit and at rest, both offer signed Business Associate Agreements. The differences hide one layer down, and they decide most procurement outcomes.
eFax is the older product. j2 Global (now Consensus Cloud Solutions) acquired the brand in 2000 and has run it as the largest commercial online fax service since. The product reflects that lineage: deep integrations, enterprise contracts, brand recognition that closes the procurement loop quickly in conservative IT shops, and a pricing posture that increasingly pushes buyers toward the Protect tier where HIPAA actually lives. The interface is functional but feels its age next to newer entrants. Mobile coverage works but has not been rebuilt around 2020s phone workflows.
SRFax is the newer specialist. Founded in 2008 in Canada, the product was designed from day one around regulated workflows — first for Ontario PHIPA, then expanded to US HIPAA. Every plan tier ships free PGP encryption. Every Healthcare plan ships a signed BAA without sales escalation. The pricing is published transparently with no surprises. SRFax does not market on celebrity, does not bundle eSignatures, and does not pretend to be all things to all buyers. For a healthcare practice that cares about compliance per dollar more than brand recognition, the SRFax pitch lands cleanly.
The practical question for most buyers is not 'which product is better' in the abstract — it is 'which product is the right fit for my specific workload, compliance pressure, and procurement constraints.' This article works through that decision in depth.

Pricing: the four-times gap and what it buys
eFax Protect costs $49.99 a month for 300 pages. SRFax Healthcare Lite costs $12.60 a month annual for 200 pages. The all-in difference is roughly $37 a month, $444 a year. For a solo practice, that is not a rounding error — it is the cost of a junior staff member's monthly health insurance.
What does the $37 difference buy on the eFax side? Bundled jSign electronic signatures, a higher page allowance on the Protect tier, and the brand-recognition halo. None of these is worthless. For a small law firm that already uses jSign for client engagement letters, the bundling argument has teeth. For a healthcare practice that handles eSignatures separately (through DocuSign, HelloSign or Dropbox Sign), the jSign bundle adds nothing.
On the SRFax side, the $12.60 plan covers a signed BAA, optional PGP encryption (included at no extra cost), audit logs and SOC 2-aligned controls per SRFax's security page. SOC 2 Type 2 and ISO 27001 attestations are not surfaced on SRFax's public pages — buyers should request the current certificates directly. For a solo psychotherapist or a single-physician clinic, the BAA plus the audited operational practices is the complete compliance footprint without paid add-ons. SRFax Healthcare Basic Plus at $22.95 covers 500 pages; Healthcare Standard at $41.35 covers 2,500 pages. The step-up curve is gentle and predictable.
The four-times gap shrinks at higher volume. eFax Pro at $19.99 a month for 200 pages is closer to SRFax Healthcare Lite pricing but does not include the HIPAA-tier BAA, which means it cannot transmit PHI without elevating the contract. A buyer comparing eFax to SRFax for healthcare cannot use eFax Pro — the comparison is structurally Protect vs Healthcare Lite, and Protect loses the price contest by a wide margin.
06
Compliance posture: paperwork that survives a vendor review
Both vendors clear the basic HIPAA bar. eFax Protect ships the BAA, publishes SOC 2 on its compliance page, encrypts AES-256 at rest, TLS 1.2+ in transit, and produces a defensible audit trail. SRFax does the same on every Healthcare-tier plan plus offers optional PGP encryption (included at no extra cost) that lets the practice control the key material end-to-end if it chooses to.
The paperwork divergence shows up when a security review pulls the full vendor questionnaire. SRFax publishes the BAA template, audit-log export and DPA but does not currently surface SOC 2 Type 2 or ISO 27001 certificates on its public security pages — buyers requiring these for procurement should request them directly. eFax publishes some of this in the customer portal but routes the deepest documentation through enterprise sales. For a solo practice, the SRFax direct-publish model is simpler. For a hospital system whose security team has an established eFax relationship, the existing access path is already greased.
PHIPA is the cleanest practical differentiator. SRFax markets Personal Health Information Protection Act coverage explicitly — Canadian-built, Ontario-anchored, with audit-log fields and BAA-equivalent agreements designed around provincial law. eFax does not market a published PHIPA stance. For an Ontario practice, the SRFax fit is direct. For a US-CA cross-border practice (a healthcare system with sites in Buffalo and Toronto, say), the SRFax single-vendor solution removes a compliance gap that eFax does not address.
The other certification gap is HITRUST CSF. Neither eFax nor SRFax holds HITRUST. Buyers whose security review specifically requires HITRUST should not select either — Documo is the alternative to evaluate.
eFax's support is broad — phone, chat, email — and the documentation library is extensive. Response times on standard plans are adequate but not standout; enterprise contracts unlock dedicated account managers. SRFax's support is narrower in channel coverage (primarily phone and email) but reviewer feedback consistently points to faster first-response and more technically competent first-line agents. The difference matters most when something breaks at the worst time.
Uptime is comparable. Both vendors target 99.9% availability with no major outage history in the last twelve months that we could verify. Neither publishes a public status page with multi-year history, which is a credit gap. For a healthcare practice where a four-hour outage during a CMS prior-authorisation window has real cost, the lack of a public uptime track record is something to flag in procurement.
Migration from eFax to SRFax (or the reverse) is straightforward but not friction-free. The fax number ports in 3-10 business days. Run dual receipt during the porting window. Audit-log history does not transfer between vendors; export from the outgoing vendor before cancellation if you need the historical record. Most practices we surveyed who switched did so over a single weekend with parallel coverage during the cutover.
The operational risk of staying on a less-fit vendor is greater than the migration friction. Healthcare practices that limp along on a plan that does not meet compliance or volume requirements accumulate breach-notification risk that the cheapest migration cost would have absorbed in a single year.
08
Edge cases: when eFax is actually the right answer
Three scenarios make eFax the rational pick despite the price gap. First, existing enterprise contracts. A hospital system already running eFax across 40 sites does not migrate for $37 a month per line — the operational risk of fragmenting the vendor relationship outweighs the savings. Second, jSign integration as a load-bearing workflow. If the practice already uses jSign for engagement documents and the bundled access reduces ops overhead, the eFax Protect price reflects two products, not one.
Third, brand-recognition procurement. Some IT shops and procurement committees move faster on names they recognise. For a department where the fax procurement is a small line item and the procurement officer's bandwidth is the bottleneck, the brand-recognition shortcut sometimes wins. We would argue this is the weakest justification but acknowledge it is real.
Outside these three cases, SRFax is the rational pick. The compliance footprint is equivalent (modulo PHIPA, which favours SRFax). The price difference is significant. The support experience is at least equivalent. The operational fit for solo and small-clinic practice is markedly better.
A fourth scenario sometimes raised — that eFax is 'more reliable because it's been around longer' — does not survive scrutiny. SRFax has run since 2008 with no major reliability incidents we could verify. Brand age is not an uptime guarantee. Procurement decisions made on this dimension alone are usually decisions made on perception, not evidence.

What to check before you sign
If you are a solo practice or a clinic under five clinicians, default to SRFax Healthcare Lite unless you have a specific reason not to. The 200-page allowance covers most low-to-moderate volume. The $12.60 monthly cost is honest. The BAA signs at checkout. There is no reason to pay four times more for the same compliance bar.
If you are a multi-site practice with growing volume, run two months on SRFax Healthcare Basic Plus at $22.95 (500 pages) or Healthcare Standard at $41.35 (2,500 pages) before committing. The upgrade path inside SRFax is gentle. If volume turns out to exceed Healthcare Standard, the conversation shifts to Fax.Plus Enterprise or Documo, not eFax — at high volume, eFax's price-per-page does not catch back up.
If you already run eFax at scale, do not migrate without a clear operational driver. Switching costs at scale absorb the savings for at least 12-18 months. The right moment to revisit is when the contract comes up for renewal or when a new requirement (PHIPA, HITRUST, SCIM) makes the existing fit insufficient.
If you handle eSignatures and want them bundled with fax in one vendor, eFax Protect with jSign is the cleaner pick. If eSignatures live in a separate product (DocuSign, HelloSign), the bundling argument does not apply and the price gap reverts to SRFax's favour.

Frequently asked questions
01Is SRFax HIPAA-compliant on the entry plan?
SRFax Basic plans do not include the BAA. The HIPAA-compliant plans start with Healthcare Lite at $12.60 a month, which signs the BAA at checkout. Healthcare Basic Plus at $22.95 and Healthcare Standard at $41.35 also include the BAA. For PHI transmission, you need a Health-tier plan.
02Is eFax HIPAA-compliant on Plus or Pro?
No. eFax Plus and Pro do not include the BAA. HIPAA coverage starts with eFax Protect at $49.99 a month. Plus and Pro can transmit non-PHI documents safely but cannot legally handle PHI without elevating to Protect.
03Does SRFax work for US-only practices?
Yes. SRFax operates US data centres alongside Canadian and serves US healthcare practices on Health-tier plans with US HIPAA coverage. The Canadian origin and PHIPA option are advantages for cross-border practices but do not create any disadvantage for US-only buyers.
04How do their audit trails compare?
Both produce defensible HIPAA-grade audit trails. SRFax exports CSV/PDF logs from every Health-tier plan. eFax Protect exports comparable logs but the export depth on Plus/Pro is shallower. For pure audit-trail completeness on the entry HIPAA tier, SRFax wins.
05What is the cleanest migration path between the two?
Port the fax number to the new vendor (3-10 business days). Run dual receipt during the porting window. Export the historical audit log from the outgoing vendor before cancellation. Sign the new BAA. Cancel the old account. The whole process typically takes a single weekend with planning and a two-week tail for log export.
06Which one is better for Canadian healthcare?
SRFax. The product was built around Ontario PHIPA from inception. eFax does not market a published PHIPA stance. For Canadian healthcare practices, SRFax is the right answer without close competition.
The verdict
SRFax delivers more compliance value per dollar for healthcare practices and small-to-mid clinics. eFax's Protect tier costs four times as much as SRFax Healthcare Lite and gives you fewer pages, no PHIPA option, and an interface that has not modernised as quickly as competitors. If you do not already run eFax in production and you are not bound by an existing enterprise contract, SRFax is the rational pick.
