Why is VaultMail the only HIPAA email encryption service that's actually cheap?

Enterprise email encryption suites run $25–60 per seat per month. VaultMail is $5 — or $18 with a signed BAA and a 6-year audit ledger. Here's how, and why the price gap exists at all.

Ask any practice manager who has priced out HIPAA-compliant email and you’ll hear the same story: the quote starts reasonable, then comes the per-seat minimum, the annual contract, the onboarding fee, and the “compliance tier” that actually includes the BAA. By the time the paperwork lands, a five-person clinic is looking at thousands of dollars a year — to send email safely.

The enterprise suites in this space — the Virtru, Paubox, and Zix class of products — typically run $25 to $60 per seat, per month. VaultMail is $5, the Vault Ledger plan with a six-year audit ledger is $18, and individual providers can start free. As far as we can tell, that makes VaultMail the only genuinely cheap HIPAA email encryption service on the market.

What the $60 seat actually pays for

It’s not the cryptography. AES-256 is AES-256 whether you pay $5 or $60 — the algorithms are public, standardized, and free. What the enterprise price tag funds is everything around the encryption:

• Mail infrastructure duplication. Legacy secure-email gateways re-route your mail through their own servers, which means they run (and bill you for) a parallel mail pipeline.
• Sales-led onboarding. Demos, procurement calls, and custom contracts are expensive, and that expense is priced into every seat.
• Portal bloat. Recipient portals with accounts, passwords, and password resets require support teams. Support teams require revenue.

Encryption is cheap. Enterprise software sold like enterprise software is what’s expensive.

How VaultMail gets to $5

VaultMail took the opposite architecture. It’s a Chrome extension that lives inside Gmail and Outlook compose — your mail keeps flowing through your existing provider. Messages and attachments are encrypted with AES-256-GCM, a unique key per message, and delivered by secure link, so there is no parallel mail pipeline to run. Recipients open messages with one click after verifying their email — no account, no app, no portal password — so there is no army of support staff to fund. Even the BAA is self-serve: you sign it online in about a minute on Vault Ledger.

Cheap doesn’t mean less secure

The security model is the strongest part of the product, not a casualty of the price:

• AES-256-GCM with a unique data-encryption key per message — TLS 1.3 in transit, stored only as ciphertext.
• Signed HIPAA BAA, self-serve on the Vault Ledger plan.
• Append-only audit log of every send, open, and decrypt — with a six-year ledger option for clinics that need disclosure accounting.
• Recall and expiry — revoke a mis-sent message before it’s opened, or set messages to expire on their own.

The price gap isn’t a security gap. It’s an architecture gap — and it means solo providers and small practices no longer have to choose between compliance and payroll.
