If you’re researching alternatives to Paubox for HIPAA email, you’re likely looking for a secure email solution with better flexibility, stronger controls, or broader compliance support.
Paubox is known for simple encrypted email, but some organizations may need more than a point solution — especially if they also need compliant hosting, backups, cloud infrastructure, or managed compliance support. Some third-party reviews also mention limitations around admin controls, setup complexity, storage, and pricing.

Why Organizations Look for Paubox Alternatives
Paubox can be a useful solution for HIPAA email encryption, but it may not fit every healthcare organization’s needs.
Common reasons teams compare Paubox alternatives include:
- Limited admin visibility
- Setup challenges with domains or Outlook
- Need for more complete encryption and data protection
- Limited built-in infrastructure
- Cost concerns as organizations scale
→ For organizations that need more than secure email alone, a broader platform with HIPAA-compliant email solutions and managed infrastructure may be a better fit.

Learn MoreWhat Makes an Email Solution HIPAA-Compliant?
A HIPAA email solution should help protect electronic protected health information (ePHI) through administrative, physical, and technical safeguards. The HIPAA Security Rule requires covered entities and business associates to protect the confidentiality, integrity, and availability of ePHI.
Important features include:
- Encryption for data in transit
- Access controls
- Audit controls
- Authentication
- Secure storage
- A signed Business Associate Agreement
HHS also explains that covered entities need a written business associate contract when a vendor handles protected health information on their behalf.
For secure transmission, NIST TLS guidance provides recommendations for configuring Transport Layer Security using modern cryptographic standards.

2. Nightfall AI
Nightfall AI focuses on data loss prevention across SaaS, email, AI tools, and endpoints. It is useful for organizations that need to detect sensitive data such as PHI, PII, PCI, secrets, and intellectual property across multiple systems.
Nightfall may be a good fit for teams that need advanced detection and SaaS security, but it is not primarily an email hosting provider.
3. Virtru
Virtru provides email encryption for platforms like Gmail and Microsoft 365. It is often considered by teams that want to keep their existing email environment while adding encryption and access controls.
Virtru may be useful for organizations that want granular message-level controls, but some teams may still need separate hosting, backups, or broader compliance infrastructure.
4. Zix
Zix, now part of Proofpoint, offers policy-based email encryption for enterprise organizations. It can automatically detect sensitive content and apply encryption rules.
Zix is often better suited for larger organizations with internal IT and compliance teams because setup and management can be more complex.
5. SendSafely
SendSafely provides secure file sharing and encrypted communication. It may be useful for organizations that frequently send sensitive files or need simple secure delivery workflows.
However, teams with broader HIPAA hosting or infrastructure needs may still require additional solutions.
6. Proofpoint
Proofpoint offers enterprise email security, threat protection, and data loss prevention. It is a strong option for larger organizations with mature security operations.
For smaller healthcare teams, Proofpoint may be more complex and costly than needed.

How to Choose the Right Paubox Alternative

Choose a point email encryption tool if you only need to send secure messages. Choose a broader compliance platform if you need secure email, hosting, backups, disaster recovery, monitoring, and infrastructure support.
For organizations managing PHI across multiple systems, secure HIPAA cloud infrastructure may provide better long-term protection than email encryption alone.
A good provider should offer:
- A signed BAA
- Encryption in transit and at rest
- Strong access controls
- Audit logging
- Reliable support
- Scalable infrastructure
- Clear compliance documentation

- Preparing for audits or risk reviews
→ You can also schedule a HIPAA risk assessment to identify gaps in your current email, hosting, and cloud environment.
