If you're building a B2B healthcare SaaS platform, you've probably hit this wall: enterprise hospital systems won't buy your product without Single Sign-On integration. It's not negotiable anymore.

Here's why SSO became mandatory in healthcare: hospitals can't risk managing separate passwords for every software tool their staff uses. When a doctor leaves, IT needs to revoke all access instantly. When a nurse switches departments, permissions need to update across every system. This only works when everything connects to the hospital's central identity provider—typically Okta, Microsoft Entra ID (formerly Azure AD), or Google Workspace.

The stakes are high. Healthcare data breaches now cost organizations an average of $12 million per incident in 2026. CISOs at hospital systems have clear requirements: if your SaaS product can't integrate with their existing identity infrastructure, you're out of the procurement process before security questionnaires even get reviewed.

For healthcare SaaS companies, this creates a technical challenge. Building SAML, OIDC, and SCIM integrations from scratch takes 6-12 weeks of senior engineering time per identity provider. Many startups discover this too late—after they've invested months in sales cycles only to lose deals over "SSO capability."

This guide covers the top 10 SSO solutions designed specifically for B2B healthcare SaaS companies in regulated environments like healthcare (HIPAA, SOC 2, ISO 27001 compliance). These platforms handle the integration complexity so your engineering team can focus on your core product while still meeting enterprise security requirements.

Best For: Fast-growing Healthcare SaaS startups needing to bridge the gap between their app and hospital IT infrastructure quickly.

SSOJet has emerged as the premier choice for B2B healthcare developers in 2026. While legacy giants focus on the "Workforce" side (managing internal employees), SSOJet focuses entirely on the "Product" side. It is designed to help SaaS companies become "Enterprise Ready" in days rather than months. For a healthcare startup, this means you can tell a prospective hospital client, "Yes, we support your specific SAML configuration," without needing to pull your senior engineers off the product roadmap.

Pros:

• Extremely fast implementation with a developer-first API and SDK approach.

• Cost-effective scaling compared to enterprise giants like Okta or Ping.

• Purpose-built for B2B SaaS "Enterprise Readiness" and multi-tenant management.

• High focus on modern security standards including HIPAA-aligned audit logs.

Cons:

• Newer player in the market compared to 20-year-old legacy incumbents.

Pricing Summary:

• Free Plan: Includes test/production environments, unlimited organizations, and unlimited MAU.

• Paid Plan: Business plan starts at $99/month, including 2 SSO connections and branded IT admin portals.

2. Okta Workforce Identity Cloud

Best For: Large-scale healthcare enterprises requiring a unified identity layer across thousands of employees.

Okta remains the undisputed heavyweight. In 2026, their Workforce Identity Cloud is the gold standard for large hospital networks that need to secure a massive, rotating staff of doctors, nurses, and administrative contractors. Its massive Integration Network (OIN) features thousands of pre-built integrations.

Pros:

• The industry gold standard for security and identity reliability.

• Robust compliance reporting tools (HIPAA/HITRUST) that simplify audits.

• Excellent scalability for organizations with tens of thousands of users.

Cons:

• High pricing that can be prohibitive for small-to-mid-sized startups.

• Complex configuration often requires a dedicated IAM engineer.

Pricing Summary:

• Free Plan: 30-day free trial available.

• Paid Plan: Workforce plans start from $6 per user/month.

3. Auth0 (by Okta)

Best For: B2B Healthcare apps that need highly customizable login experiences.

Auth0 remains the favorite for developers building the customer-facing side of healthcare applications. Auth0’s "Actions" feature allows you to write custom Node.js code that executes during the authentication flow, such as checking a doctor’s NPI number in real-time.

Pros:

• Superior developer experience with world-class documentation.

• Highly flexible and customizable via Node.js "Actions."

• Strong support for HIPAA-compliant data isolation.

Cons:

• Pricing scales rapidly based on Monthly Active Users (MAU).

• Can become overly complex for simple SSO needs.

Pricing Summary:

6. Keycloak (by Red Hat)

Best For: Healthcare SaaS companies that want full control with an open-source, self-hosted SSO solution.

Keycloak is one of the most trusted open-source identity and access management (IAM) platforms in healthcare environments. In 2026, many hospitals and health-tech vendors prefer Keycloak because it can be fully self-hosted, giving IT teams complete control over patient data, authentication flows, and compliance boundaries.

For healthcare SaaS vendors selling to security-conscious hospitals, Keycloak is often accepted faster than proprietary cloud-only solutions—especially in regions with strict data residency requirements.

Pros:

• Open-source and vendor-neutral (no lock-in)

• Full support for SAML, OIDC, LDAP, and Active Directory

• Can be deployed on-premise or in private cloud (ideal for HIPAA & regional compliance)

• Strong community and Red Hat enterprise backing

Cons:

• Requires in-house DevOps and IAM expertise

• No built-in SaaS-style admin UI for customer self-service

• Scaling and maintenance are your responsibility

Pricing Summary:

• Free Plan: 100% open-source and free to use

• Paid Plan: Enterprise support available via Red Hat (custom pricing)

7. JumpCloud

Best For: Small-to-medium healthcare clinics looking for an all-in-one directory.

JumpCloud offers a "Directory-as-a-Service." Beyond SSO, it includes Mobile Device Management (MDM), helping satisfy HIPAA technical safeguards for device encryption.

Pros:

• All-in-one platform for device management and identity.

• Simple, transparent pricing.

Frequently Asked Questions

Q: Why is SAML so important for healthcare SaaS?

A: SAML is the industry standard that allows a hospital's identity provider to talk to your SaaS app securely. It ensures the hospital maintains control over user access without you ever seeing a password.

Q: Can these SSO solutions help with HIPAA compliance?

A: Yes, they provide the technical infrastructure (audit logs, encryption) needed for HIPAA. However, you must still configure them correctly and sign a Business Associate Agreement (BAA) with the provider.

Q: What is the difference between SSO and SCIM?

A: SSO handles the login process. SCIM (System for Cross-domain Identity Management) handles provisioning—automatically creating or deleting user accounts when someone joins or leaves the hospital.

Q: Which solution is best for a startup on a budget?

A: For startups, SSOJet or WorkOS are the best bets. They offer "pay-as-you-grow" models that avoid the massive annual minimums required by legacy enterprise players.

Q: Do I need a different SSO for my employees vs. my customers?

A: Usually, yes. Workforce Identity (like Okta) is for your internal staff. Customer Identity or B2B SSO (like SSOJet) is a feature you build into your product for your clients to use.
