Best HIPAA-Compliant Secure Messaging for Clinics

Pick the right shape before you pick the vendor

Secure messaging splits cleanly into two problems: clinicians messaging each other about patient care, and clinicians messaging patients. Both need a signed BAA, but they need different features. Shortlists that blur the two end up with a tool that does neither well.

All five vendors below provide a BAA on their paid plans. None of their free or trial tiers should be used for PHI.

The five vendors clinics actually evaluate

TigerConnect. Clinician-to-clinician focused, with strong on-call scheduling, role-based paging, and EHR integration. Widely used in hospital and multi-site group practices where “who is on call for cardiology tonight” is a daily question.

OnPage. Clinician-to-clinician focused with an emphasis on critical alerting and escalation. Stronger at paging-style urgent workflows than at casual team chat.

Halo Health. Clinician-to-clinician and clinical team collaboration. Similar category to TigerConnect with focus on care-team coordination and role-based routing.

Spruce Health. Clinician-to-patient focused. Unified inbox for SMS, voice, fax, and secure chat with patients. A good fit for independent and small-group clinics that want a single patient-communication channel under a BAA.

Klara. Clinician-to-patient focused. Two-way patient messaging with EHR integration. Leans toward specialty clinics (dermatology, aesthetics, mental health) that do high-volume patient back-and-forth.

The comparison that actually matters

Vendor	BAA	Primary use	Audit trail	Pricing model
TigerConnect	Included on paid plans	Clinician-to-clinician	Message-level logs	Per-user
OnPage	Included on paid plans	Critical paging	Message-level logs	Per-user
Halo Health	Included on paid plans	Care-team collaboration	Message-level logs	Per-user
Spruce Health	Included on paid plans	Clinician-to-patient	Message-level logs	Per-provider
Klara	Included on paid plans	Clinician-to-patient	Message-level logs	Per-provider

Pricing details change; ask the vendor and confirm the BAA is included on the plan you are buying.

Policy is where most programs fail

Signing a BAA and buying the tool is the easy part. The program work is the policy:

• Who is allowed to message patients, and from what device.
• What types of PHI are appropriate for messaging versus a phone call.
• Retention period for messages and how they link back to the chart.
• What happens when a workforce member leaves and still has the mobile app installed.
• How a patient’s revocation of consent to text is recorded and enforced.

These are acceptable-use and workforce policies. They belong in your policy library with signed attestations, not in a Slack announcement that nobody remembers three months later.

What secure messaging does not cover

The messaging vendor handles the transmission and the logs. It does not run your compliance program. Training cadence, BAA register, incident log, and access reviews live in the operating layer. See PHIGuard pricing or the full HIPAA software comparison for that layer. For the underlying rules, see HIPAA basics. Telehealth-first practices should also review HIPAA software for telehealth providers since messaging and video policy usually ship together.

The practical rule: if it is PHI, it does not belong in a personal SMS thread. Ever.
