B2B Authentication Provider Comparison: Features, Pricing & SSO Support (2026)

Tue, 28 Apr 2026 20:29:55 +0000

Enterprise SaaS buyers now expect SSO and SCIM support by default.

Most enterprise security teams will reject SaaS products that do not support SSO. Identity infrastructure has become a core requirement for B2B SaaS platforms.

Modern authentication providers help SaaS companies integrate:

Enterprise Single Sign-On (SSO)
Directory synchronization
SCIM user provisioning
Multi-factor authentication
Passwordless login

Instead of building authentication infrastructure internally, most SaaS companies rely on specialized identity platforms.

Below is a quick comparison of the leading B2B authentication providers in 2026.

Quick Comparison of Authentication Providers

Enterprise authentication platforms differ significantly in architecture and pricing models.

Some providers offer complete identity platforms, while others focus on enterprise SSO infrastructure.

For example:

Auth0 provides a full CIAM platform covering authentication, MFA, and user management.
Okta dominates enterprise workforce identity.
SSOJet focuses on enterprise SSO integrations for SaaS apps.

However, many modern B2B SaaS companies prefer dedicated enterprise SSO platforms designed specifically for multi-tenant SaaS architectures.

This is where platforms like SSOJet stand out.

Instead of replacing your authentication system, SSOJet allows SaaS companies to add enterprise SSO and SCIM provisioning quickly without rebuilding their identity stack.

This approach is particularly valuable for SaaS startups and mid-market platforms that want to support enterprise customers without complex identity infrastructure.

Key Authentication Trends in 2026

The authentication landscape is evolving rapidly as organizations prioritize stronger identity security and seamless access management. Several major trends are shaping the identity and authentication market in 2026.

1. Enterprise SSO Becoming a Standard Requirement

Enterprise Single Sign-On (SSO) is no longer considered an optional feature. Most enterprise customers now require SSO support as part of their vendor procurement process.

Organizations expect SaaS platforms to integrate with existing identity systems to simplify user management and improve security. Supporting standards like SAML and OpenID Connect has become essential for B2B applications.

2. Rapid Growth of Passwordless Authentication

Traditional password-based authentication is gradually being replaced by passwordless methods.

Technologies such as Passkeys and WebAuthn are gaining adoption because they:

eliminate password-related security risks
reduce phishing vulnerabilities
improve user experience

Many modern authentication platforms now prioritize passwordless login as a core capability.

3. Identity Security Moving Toward Zero-Trust

Security architectures are shifting toward Zero Trust Architecture, where access decisions are based on verified identity signals rather than network location.

In this model:

every access request is verified
user identity and device signals are continuously evaluated
trust is never assumed

Identity providers and authentication platforms play a central role in enabling these zero-trust security models.

4. Expansion of Enterprise Identity Integrations

Modern organizations rely on multiple identity providers and enterprise platforms to manage user access across their technology stack.

Common identity providers used by enterprises include:

Okta
Microsoft Entra ID
Google Workspace
Ping Identity

As a result, SaaS companies must support seamless identity integrations to enable enterprise customers to authenticate users using their existing identity systems.

Why This Comparison Matters

Choosing the wrong authentication platform can create major technical and financial problems later.

Identity infrastructure directly impacts:

Security
Enterprise Sales
Developer Productivity
Platform Scalability

A poorly chosen identity provider can make it difficult to support enterprise customers.

On the other hand, the right provider can dramatically accelerate enterprise onboarding and reduce engineering complexity.

Why Authentication Infrastructure Is Critical for B2B SaaS

Authentication is no longer just a login feature.

For modern SaaS platforms, identity infrastructure directly impacts security, enterprise sales, and user management.

Enterprise customers expect SaaS applications to support secure authentication standards and identity federation. Without these capabilities, many companies cannot even begin a security review.

Below are the key reasons why authentication infrastructure has become essential for B2B SaaS products.

Enterprise Customers Require SSO

Enterprise companies typically manage employee access through a centralized identity provider.

These identity providers control:

Employee Authentication
Application Access
Security Policies
Multi-factor Authentication

Instead of creating separate accounts for every SaaS application, employees sign in using Single Sign-On (SSO).

SSO allows a company’s identity provider to authenticate users across multiple applications.

For example, a company using Okta can allow employees to log into a SaaS product using their corporate account.

This approach improves security and reduces password management issues.

However, it also means that SaaS companies must integrate with enterprise identity providers to support SSO.

Platforms like SSOJet and WorkOS help SaaS applications quickly add enterprise SSO integrations without building complex identity infrastructure.

Enterprise Procurement Requires Identity Integration

SSO is often a mandatory requirement during enterprise procurement.

Security teams typically evaluate SaaS vendors based on their identity and access management capabilities.

Common enterprise requirements include:

SAML SSO support
SCIM Provisioning
Multi-Factor Authentication
Role-Based Access Control
Audit Logging

If a SaaS product cannot support enterprise identity standards, it may fail security reviews.

This is one of the main reasons many SaaS startups adopt dedicated authentication platforms such as:

Auth0
SSOJet
WorkOS

These platforms simplify enterprise identity integrations and reduce development effort.

SCIM Automates User Provisioning

Managing user accounts manually becomes difficult for large organizations.

When a new employee joins a company, the IT team needs to create accounts across multiple SaaS tools.

When an employee leaves, those accounts must be removed immediately.

SCIM (System for Cross-domain Identity Management) solves this problem.

SCIM allows enterprise identity providers to automatically:

Create User Accounts
Update User Information
Deactivate Accounts

This process is called automated user provisioning.

For SaaS companies selling to enterprises, SCIM support is becoming just as important as SSO.

Platforms such as SSOJet and WorkOS provide built-in SCIM provisioning to simplify enterprise onboarding.

Security Risks of Building Authentication Internally

Some SaaS teams attempt to build authentication systems from scratch.

While this may seem simple initially, identity systems quickly become complex.

Authentication infrastructure must support:

Password Hashing and Security
Multi-Factor Authentication
Session Management
Token Handling
Identity Federation
Enterprise SSO Protocols

Maintaining these systems securely requires significant engineering effort.

Security vulnerabilities in authentication systems can lead to:

Account Takeovers
Data Breaches
Compliance Violations

For this reason, most SaaS companies rely on specialized identity providers rather than building authentication internally.

Platforms like Auth0 provide a complete identity platform, while providers like SSOJet focus specifically on enterprise SSO infrastructure.

Identity Has Become the Security Perimeter

Modern cloud applications no longer operate within traditional network boundaries.

Employees access SaaS platforms from:

Remote Locations
Mobile Devices
Multiple Networks

Because of this, security teams increasingly rely on identity-based security models.

In a zero-trust architecture, identity verification becomes the primary method of controlling access.

Authentication providers play a central role in this model by managing:

User Authentication
Identity Federation
Access Policies
Security Signals

This shift is one reason why identity infrastructure has become a critical component of SaaS architecture.

Why Many B2B SaaS Platforms Use Dedicated SSO Providers

Supporting enterprise authentication standards can significantly slow product development.

Implementing SAML integrations with multiple enterprise identity providers often requires:

Complex Protocol Handling
Metadata Configuration
Certificate Management
Security Testing

Dedicated enterprise SSO providers simplify this process.

Platforms like SSOJet provide ready-to-use integrations with enterprise identity providers, allowing SaaS companies to support enterprise authentication quickly.

This enables SaaS teams to focus on their core product rather than building identity infrastructure.

Core Authentication Protocols Every SaaS Company Should Know

Enterprise authentication relies on a few core identity standards.

These protocols allow SaaS applications to integrate with enterprise identity providers and support secure login flows.

Most modern SaaS authentication platforms support the following protocols:

SAML
OAuth 2.0
OpenID Connect (OIDC)
SCIM

Understanding these protocols helps SaaS teams choose the right authentication provider.

SAML (Security Assertion Markup Language)

SAML is the most widely used protocol for enterprise Single Sign-On (SSO).

SAML allows an enterprise identity provider to authenticate users for external applications.

In a typical SAML login flow:

A user attempts to access a SaaS application.
The application redirects the user to their company’s identity provider.
The identity provider authenticates the user.
The identity provider sends a signed authentication response back to the application.

The SaaS application trusts this response and grants access.

SAML is commonly used by enterprise identity providers such as:

Okta
Google Workspace
Microsoft identity services

Because SAML integrations can be complex, many SaaS companies rely on platforms like SSOJet or WorkOS to simplify implementation.

OAuth 2.0

OAuth 2.0 is an authorization framework.

It allows applications to access resources on behalf of a user without sharing passwords.

OAuth is commonly used for:

API access
third-party integrations
delegated permissions

For example, when a SaaS application asks to access a user's Google Drive files, it typically uses OAuth authorization.

OAuth does not authenticate users directly. Instead, it provides access tokens that allow applications to access specific resources.

OpenID Connect (OIDC)

OpenID Connect is an authentication layer built on top of OAuth 2.0.

OIDC allows applications to verify a user’s identity.

Unlike OAuth, which focuses on authorization, OpenID Connect provides authentication information.

OIDC is widely used for modern applications because it supports:

Mobile Applications
Web Applications
API-Based Authentication

Many modern authenticati
