Choosing a cloud fax service means weighing encryption standards, HIPAA compliance, pricing tiers, and integrations — all at once. This comparison breaks down every key feature so you can match the right platform to your industry, team size, and budget.
Frequently Asked Questions
What is a cloud fax service?
A cloud fax service routes fax transmissions over the internet instead of analog phone lines. Users send and receive faxes through a web portal, mobile app, or email — no fax machine or dedicated phone line required. Documents are encrypted in transit (TLS) and at rest (AES-256).
Is cloud fax HIPAA compliant?
Cloud fax can be HIPAA compliant, but only if the provider signs a Business Associate Agreement (BAA) and uses AES-256 encryption plus audit logging. Not every provider offers this. See our guide to [HIPAA fax requirements](/blog/hipaa-fax-requirements/) for the full checklist.
How much does a cloud fax service cost per month?
Starter plans run $6–$15/month for 100–300 pages. Professional plans with HIPAA compliance and team features cost $20–$50/month. High-volume enterprise plans start around $75–$200/month or are custom-quoted.
Can I keep my existing fax number when switching to cloud fax?
Yes. Most major cloud fax providers — including mFax Business, eFax, RingCentral, and Fax.Plus — support number porting. The transfer typically takes 5–10 business days.
Do I need a phone line for cloud fax?
No. Cloud fax works entirely over the internet. You can eliminate your dedicated fax phone line — saving $30–$60/month — and send faxes from any device with a web browser or mobile app.
