HIPAA Compliant Texting Platform: The Complete Buyer’s Guide

A HIPAA compliant texting platform is not the same thing as an app with strong encryption. It is a system built with the administrative, physical, and technical safeguards the HIPAA Security Rule requires, backed by a signed Business Associate Agreement (BAA) with the vendor. Most standard SMS apps fail this test entirely, not because the message itself is unencrypted, but because the carrier handling that message will not sign a BAA and has no obligation to control who accesses the metadata attached to it.

This guide compares seven platforms relevant to a healthcare organization’s secure communication stack, spanning clinical texting, patient engagement, enterprise messaging suites, and on-premise secure communications infrastructure: TigerConnect, Spruce Health, OhMD, Klara, Imprivata Cortext, Microsoft Teams, and TrueConf.

Each is assessed on BAA availability, encryption model, deployment flexibility, and where it realistically fits inside a covered entity’s technology stack.

Quick Answer: Which Platform Should You Choose?

If your priority is…	Choose	Why?
Large hospital systems with clinical care team coordination	TigerConnect	Widely adopted in hospital environments with role based routing and on-call scheduling built in
Solo providers and small practices	Spruce Health	Full communication suite (texting, calling, video) priced and packaged for small teams
Patient-to-provider texting without app friction	OhMD	Patients text a normal looking number, no separate app download required on their side
Patient communication and digital intake	Klara	Texting combined with intake forms and pre-visit workflows
Large enterprise hospitals with existing badge and identity infrastructure	Imprivata Cortext	Deep integration with Imprivata’s single sign-on and identity governance already used in many hospital systems
Organizations already standardized on Microsoft 365	Microsoft Teams	HIPAA-eligible messaging and video under a signed BAA within an existing Microsoft tenant
Secure, on-premise video and communications infrastructure with no cloud dependency	TrueConf	Runs entirely on the organization’s own infrastructure, including air-gapped networks, for institutions that cannot route PHI-adjacent communication through any third party cloud

TrueConf is not a texting platform in the same sense as TigerConnect or OhMD. It is a secure video conferencing and communications platform that healthcare organizations deploy on-premise when telehealth visits, internal clinical video consults, or any PHI-adjacent live communication cannot legally or contractually pass through a third party commercial cloud.

Organizations building a full secure communications stack often pair a dedicated HIPAA compliant texting platform for message based workflows with TrueConf for the video layer, particularly in government health systems, defense-affiliated medical facilities, and health systems operating under especially strict data residency requirements.

TigerConnect, Spruce Health, OhMD, and Klara are the right choice when the core need is text based clinical or patient communication inside a standard cloud hosted, BAA covered service, while Imprivata Cortext and Microsoft Teams fit organizations that want messaging tied to an existing enterprise identity and collaboration ecosystem.

Our Rating

Platform	Compliance Depth	Clinical Workflow Fit	Deployment Flexibility	Overall Score (out of 10)
TigerConnect	9	9	6	8.6
Imprivata Cortext	9	8	6	8.3
TrueConf	8	4	10	8.1
Klara	8	7	6	7.8
Microsoft Teams	7	6	6	7.4
OhMD	7	7	5	7.3
Spruce Health	7	6	5	7.0

 

Scores weigh how directly each platform supports HIPAA required safeguards against how well it fits real clinical or administrative workflows, and how much control an organization has over deployment. TrueConf scores lower on clinical workflow fit because it is not a texting platform at all, and highest on deployment flexibility because on-premise deployment removes the third party hosting questions that every cloud only vendor in this list has to answer contractually rather than architecturally.

Why Standard SMS Texting Puts PHI at Risk?

Three gaps separate standard SMS from a compliant platform:

• First, native SMS messages are not encrypted end to end and can sit unencrypted on carrier infrastructure and on the device itself with no access control beyond the phone’s lock screen.
• Second, there is no audit trail: a covered entity cannot produce a log showing who read a message, when, or from which device, which is a specific requirement under the HIPAA Security Rule’s audit control standard.
• Third, a lost or stolen phone with SMS history containing PHI has no remote wipe mechanism tied to the organization’s device management policy, unlike a compliant platform where a lost device’s message access can be revoked centrally.

Vendor Analysis

TigerConnect

TigerConnect is a clinical collaboration platform built specifically for hospital care team communication, combining secure texting with on-call scheduling, care team roles, and alarm and alert integration. It is one of the most widely deployed platforms of its kind in large hospital systems, largely because it was built around clinical workflows rather than adapted from a general purpose messaging app.

Collaboration model: Messages route to roles (the on-call cardiologist, the charge nurse for a specific unit) rather than only to named individuals, which matters in a hospital where the specific person filling a role changes shift to shift.

Data privacy: TigerConnect signs a BAA, supports full encryption in transit and at rest, and provides detailed audit logging designed specifically to support HIPAA compliance reporting during an audit.

Spruce Health

Spruce Health is a communication suite built for solo providers and small practices, bundling secure texting, calling, and video into one platform rather than requiring a practice to stitch together separate tools for each channel.

Collaboration model: A single shared business number handles patient texting, team messaging, and calls, which suits a small practice that cannot justify separate systems for each communication type.

Data privacy: Spruce Health signs a BAA and provides encryption for messages and stored data, with practice level admin controls over who can access which conversations.

OhMD

OhMD is built around patient-to-provider texting without requiring the patient to download a separate app. Patients text what looks like a normal business number, while the provider side manages the conversation through OhMD’s compliant platform.

Collaboration model: Removing the patient side app requirement measurably increases patient response rates compared to platforms that require a portal login or app install before a patient can read a message.

Data privacy: OhMD signs a BAA and secures the provider side conversation with encryption and access controls, while the patient facing side functions like a normal text conversation from the patient’s perspective.

Klara

Klara combines secure texting with digital intake forms and pre-visit workflows, positioning itself less as a pure messaging tool and more as a patient communication and intake platform that happens to use texting as the delivery channel.

Collaboration model: Conversations can trigger structured workflows, such as sending an intake form automatically after a patient’s first text, which reduces manual staff work compared to a platform that only handles free text messaging.

Data privacy: Klara signs a BAA and applies encryption and access controls consistent with other platforms in this category, with intake form data subject to the same compliance safeguards as message content.

Imprivata Cortext

Imprivata Cortext is built for large enterprise hospitals already using Imprivata’s identity and access management infrastructure, extending that same single sign-on and identity governance into secure clinical texting.

Collaboration model: Because Cortext shares identity infrastructure with the rest of an Imprivata deployment, a clinician’s access to texting is governed by the same badge tap or biometric authentication already used for EHR access, reducing the number of separate credentials staff have to manage.

Data privacy: Cortext signs a BAA and inherits the access governance strength of the broader Imprivata identity platform, which is a meaningful advantage for hospitals that already rely on Imprivata for clinical workstation access.

Microsoft Teams

Microsoft Teams can operate as a HIPAA eligible messaging and video platform when an organization has a signed BAA with Microsoft covering its Microsoft 365 tenant, extending the same compliance boundary that governs email and documents to chat and meetings.

Collaboration model: Clinical and administrative staff already using Microsoft 365 for email and documents get messaging and video inside the same governed tenant, rather than adding a separate vendor relationship purely for texting.

Data privacy: Teams inherits Microsoft 365’s BAA coverage and broader compliance certifications, though organizations must confirm the specific configuration and licensing tier in use actually falls under the signed BAA, since not every Microsoft 365 feature is automatically covered.

TrueConf

TrueConf is a secure video conferencing platform built around on-premise and hybrid deployment, and in a healthcare context it functions as the video layer of a secure communications stack rather than a texting platform. TrueConf Server installs directly on an organization’s own infrastructure, including fully air-gapped networks with no external internet connection, which places it in a different category from every cloud hosted texting vendor in this comparison.

Collaboration model: TrueConf delivers live video consults and multipoint conferencing for telehealth and internal clinical communication, making it a foundation layer that a dedicated HIPAA compliant texting platform can sit alongside rather than compete with.

Data privacy: Because on-premise TrueConf Server keeps all video and session data inside the organization’s own network, it avoids the third party hosting and BAA scope questions that every cloud based texting vendor in this list has to answer contractually, and it integrates with an organization’s existing Active Directory for authentication.

On-Premise and Secure Communications Considerations

Most healthcare organizations never need an on-premise communications layer, because a properly signed BAA with a cloud vendor satisfies their compliance obligation. But the BAA model has a structural limit worth naming directly.

On-premise deployment removes the BAA scope question rather than negotiating it favorably. When TrueConf Server runs entirely inside an organization’s own network, there is no third party processor handling PHI-adjacent video at all, so there is no BAA scope to define, audit, or renegotiate when the vendor changes its infrastructure or subprocessors.

This is structurally different from every cloud hosted texting platform in this comparison, where the BAA has to be reviewed each time the vendor updates its subprocessor list or infrastructure footprint.

This distinction matters most for government health systems, defense-affiliated hospitals, and organizations operating under data residency requirements stricter than HIPAA alone imposes. For a typical outpatient practice or hospital system, the BAA backed cloud platforms covered above are sufficient, and adding an on-premise layer would introduce infrastructure overhead without a compliance gap that actually needs closing.

What to Look For in a HIPAA Compliant Texting Platform?

A signed BAA is the non-negotiable starting point, but it is not sufficient on its own. Confirm the platform provides encryption at rest, not only in transit, since data sitting on a server between messages is a common audit gap.

Confirm audit logging captures enough detail to reconstruct who accessed a specific message during an OCR investigation, not just that a login occurred. Confirm remote wipe and automatic session timeout are configurable at the organization level rather than left to individual user settings, and confirm the vendor’s subprocessor list is disclosed and reviewed as part of the BAA, not treated as a black box.

Common Use Cases for HIPAA Compliant Texting

Care team coordination inside a hospital, where role based routing gets a message to whichever clinician is currently on call rather than a specific named individual, is the most common enterprise use case and the reason platforms like TigerConnect and Imprivata Cortext lead in hospital deployments. Patient facing use cases, including appointment reminders, no-show reduction, and digital intake, are the primary driver behind OhMD and Klara adoption in outpatient practices.

On-call escalation and critical alerting round out the category for smaller teams that need a lighter weight platform focused on urgent notification rather than full clinical workflow integration. Telehealth video visits and internal clinical video consults, particularly in organizations with strict data residency requirements, are where a video layer like TrueConf becomes relevant alongside whichever texting platform handles the organization’s message based workflows.

FAQ

What makes a texting platform HIPAA compliant rather than just encrypted?

A HIPAA compliant texting platform combines technical safeguards, including encryption at rest and in transit, audit logging, and access controls, with a signed Business Associate Agreement that makes the vendor contractually responsible for protecting PHI. Encryption alone, without a BAA and audit trail, does not satisfy HIPAA’s Security Rule. TrueConf follows the same principle on the video side of a secure communications stack, since its on-premise deployment model removes the BAA scope question entirely by keeping data off third party infrastructure.

Is standard SMS ever acceptable for sending PHI?

No. Standard SMS lacks encryption at rest, carriers will not sign a BAA, and there is no audit trail showing who accessed a message. Any PHI sent through native SMS is a reportable breach risk, which is why platforms like TigerConnect, OhMD, and Klara exist specifically to provide a compliant alternative, and why organizations needing video rather than text turn to a platform like TrueConf that offers the same on-premise data control for live communication.

What is the difference between TrueConf and a dedicated HIPAA compliant texting platform?

TrueConf is a secure video conferencing platform, not a texting platform, so it does not offer patient texting, intake automation, or role based message routing the way TigerConnect, OhMD, or Klara do. Instead, TrueConf provides on-premise video infrastructure for telehealth visits and internal clinical video consults, which organizations typically deploy alongside a dedicated texting platform rather than as a substitute for one.

Can a small practice afford a HIPAA compliant texting platform?

Yes, several platforms in this category, including Spruce Health and OhMD, are priced and packaged specifically for solo providers and small practices rather than large hospital systems. Larger organizations with more complex identity and video requirements, including those needing TrueConf’s on-premise deployment, typically have larger budgets and dedicated IT staff to match, so cost scales roughly with organizational complexity rather than being a barrier at the small practice level.

Does a signed BAA guarantee full HIPAA compliance?

No. A BAA establishes the vendor’s contractual responsibility, but the covered entity still has to configure the platform correctly, train staff, enforce access controls, and audit usage. TrueConf’s on-premise model reduces one category of this burden by removing third party subprocessor risk for the video layer, but it does not eliminate the organization’s own responsibility to configure access controls and audit logging correctly.

How do compliance officers manage risk from a vendor’s subprocessors?

Every cloud texting vendor relies on its own subprocessors for hosting, backup, and other infrastructure, and a breach at any of them creates liability for the covered entity, not just the primary vendor. Compliance officers should require subprocessor disclosure as part of the BAA review for platforms like TigerConnect, Klara, or Microsoft Teams, while an on-premise platform like TrueConf removes this specific risk category for the video layer by keeping data on the organization’s own infrastructure.

What is the biggest real world risk in HIPAA texting compliance?

Shadow IT, specifically staff texting PHI on personal phones because the compliant platform feels slower than native SMS, is the most consistent real world risk across healthcare organizations, more common than any specific encryption weakness. This is true whether the organization uses TigerConnect, OhMD, Klara, or pairs a texting platform with TrueConf for video, which is why interface speed and staff adoption matter as much as the underlying security architecture when selecting a platform.
