Encryption Types & Security Standards
The HIPAA Security Rule (45 CFR §164.312(e)) requires encryption of ePHI in transit. The regulation is “addressable” — meaning you must implement it unless you can document why an alternative is equally effective. In practice, every auditor expects encryption. See our HIPAA encryption requirements guide for the full regulatory breakdown.
Key distinction: TLS encrypts email in transit between mail servers, but the email is stored unencrypted at the destination. End-to-end encryption (E2EE) keeps the message encrypted even after delivery — only the intended recipient can decrypt it.
| Provider | Encryption Type | Recipient Experience | Certifications |
|---|---|---|---|
| Paubox | Seamless TLS + fallback AES | Opens in inbox — no portal | HITRUST CSF, SOC 2 Type II |
| Virtru | Client-side E2EE | Secure Reader (browser-based) | SOC 2 Type II, FedRAMP |
| Hushmail | Portal-based encryption | Secure portal login required | SOC 2 Type II |
| Google Workspace | TLS (S/MIME optional) | Normal Gmail inbox | SOC 2, ISO 27001, FedRAMP |
| Microsoft 365 | OME + Azure RMS | Portal or Outlook plugin | SOC 2, ISO 27001, HITRUST |
| LuxSci | Flexible (TLS/PGP/Portal) | Configurable per recipient | SOC 2 Type II, HITRUST |
Compliance tip: Regardless of which provider you choose, document your encryption controls in a risk assessment. Auditors want to see written evidence that you evaluated email security, not just that you bought a product.
Pricing Comparison
Email encryption costs range from under $10/month for basic TLS compliance to $30+/month for seamless end-to-end encryption. Remember that the cost of a HIPAA violation starts at $145 per violation and can reach $2.19 million per year.

|---|---|---|---|---|
| Paubox | $29/mo/user | All plans | 14 days | Includes email encryption + DLP on premium |

Best Provider by Use Case
The “best” HIPAA email solution depends entirely on your practice type and workflow. A solo therapist has different needs than a 200-provider health system. Before committing, verify the vendor will sign a Business Associate Agreement and review your compliance checklist for email-specific requirements.
Solo Practice
Hushmail
Lowest cost per user, BAA included, built-in secure forms for patient intake. No IT staff needed to set up or maintain.
Group Practice (5-50 providers)
Paubox
Automatic encryption eliminates human error. Staff send email as usual — Paubox encrypts in the background. Integrates with existing Gmail or Outlook.
Billing Company / Clearinghouse
LuxSci
Flexible encryption methods (TLS, PGP, portal) to match each payer's requirements. Built-in archiving satisfies retention rules.
Therapists & Counselors
Hushmail
Affordable, includes HIPAA-compliant intake forms, and the secure portal is simple enough for patients unfamiliar with encryption.
Already on Google Workspace
Google Workspace + Paubox
Keep your existing Gmail workflow. Add Paubox as an encryption layer for outbound PHI emails. BAA covers Gmail, Drive, and Calendar.
Enterprise / Hospital System
Microsoft 365 + Virtru
M365 provides the infrastructure, Compliance Center, and DLP policies. Add Virtru for granular access controls and message-level revocation.
HIPAA Email Compliance Requirements
Buying a HIPAA-compliant email service does not make you compliant. You must also configure it correctly and maintain documentation. Use our risk assessment template to document your email security controls per 45 CFR §164.312.
Signed BAA with email provider
CriticalYour email provider is a business associate under HIPAA. Without a signed BAA, sending any PHI via email is a violation — even if the email is encrypted.
Encryption of ePHI in transit
CriticalPer 45 CFR §164.312(e)(1), ePHI must be encrypted when transmitted electronically. TLS 1.2+ is the minimum standard; E2EE provides stronger protection.
Access controls on email accounts
RequiredUnique user IDs, strong passwords, and MFA on every email account that handles PHI. Shared email addresses (info@, billing@) must still have individual access logs.
Disable auto-forwarding and POP/IMAP
RequiredAuto-forwarding can route PHI to personal accounts. Disable POP/IMAP access unless those connections are also encrypted and covered by your BAA.
Email retention and disposal policy
RequiredHIPAA requires policies for retaining and securely disposing of ePHI. Document how long emails containing PHI are stored and how they are purged.
