Best Alternatives to Enterprise SSO Leaders in 2026

PingOne, from Ping Identity, is built for organisations with many apps, partners, and identity sources to connect. It supports common federation standards, so a company can link internal directories, partner systems, and cloud apps under one set of access policies. That breadth is why large enterprises choose it when a simpler SSO tool runs out of room.

The trade-off is effort and cost. Pricing is quoted, and a full rollout usually needs identity expertise on staff or from a partner. Smaller teams will find the setup heavier than they need. For a large organisation replacing or complementing a market leader, PingOne is a serious, proven alternative.

OneLogin is our pick for mid-market teams that want SSO live quickly. It offers thousands of pre-built connectors, so common apps like Salesforce, Google Workspace, and Slack can be connected without custom work. Pricing starts at $4 per user per month on its entry workforce plan, and adaptive authentication helps flag risky logins without annoying every user.

OneLogin is less of a full device and directory replacement than JumpCloud, so teams that also need device management will need another tool. Some advanced provisioning features also sit on higher tiers. For focused SSO and multi-factor authentication, it hits a good balance of price and simplicity.

JumpCloud replaces an on-premises directory as well as providing SSO, which makes it attractive to companies without Active Directory in the office. Staff get one identity for apps, devices, WiFi, and VPN, and IT manages it all from one console. The SSO plan starts at $11 per user per month billed annually, and a free tier covers very small teams.

The cost adds up as headcount grows, and teams that only need SSO may pay for directory features they do not use. JumpCloud also asks more of IT than a pure SSO add-on, since it becomes the core directory. For distributed teams on mixed devices, that consolidation is often worth it.

Keycloak is the open-source option that many engineering teams reach for first. It provides single sign-on, social login, user federation, and admin consoles, and it runs on your own servers or cloud infrastructure. There is no licence fee, which makes it appealing for startups, internal tools, and projects with tight budgets.

The real cost is time. Your team owns hosting, upgrades, backups, and security patching, and a production setup needs care around availability and monitoring. Keycloak also lacks the vendor support contract that larger buyers often require, unless you buy support separately. If you have the engineering capacity, it is a capable and flexible alternative.

Auth0, now part of Okta as a separate product, is best known for customer identity: login, sign-up, social login, and passwordless options for apps and websites. Developers can add authentication with SDKs and pre-built login pages, and the free tier covers early-stage products. Paid plans start at $35 per month.

Auth0 is less suited as a pure workforce directory replacement, since its strength is customer-facing apps rather than managing staff devices. Costs also rise with monthly active users, so a fast-growing consumer app should model that growth before committing. For product teams shipping customer login, it remains a strong pick.

CyberArk Identity brings SSO together with the company's strength in privileged access and credential security. That background appeals to banks, healthcare organisations, and other regulated teams that need tight control over who reaches sensitive systems. It offers adaptive authentication and lifecycle management alongside SSO.

Pricing is quoted, and the wider CyberArk platform can feel like more than a small team needs if the goal is only SSO for a handful of apps. For security-led buyers who already care about privileged accounts, though, the combination of workforce SSO and privileged controls in one vendor is a genuine advantage.

Frontegg solves a different problem from most tools here: it gives your SaaS product enterprise-ready login for its business customers. That means your customers can use their own SSO, manage their team roles, and review audit logs, without your team building all of that from scratch. It is aimed at B2B SaaS companies that keep losing deals because they lack enterprise login features.

Frontegg is not the tool for managing your own employees' access to internal apps, so do not buy it for that job. Pricing is also quoted rather than self-serve. If you sell software to companies and need customer SSO fast, it is a focused and practical choice.

WorkOS gives developers the building blocks for enterprise features inside their own product, including SSO, directory sync, and audit logs. Its documentation and APIs are designed for engineering teams that want to ship enterprise readiness without building SAML integrations app by app. That developer focus is its main appeal.

WorkOS is a set of APIs for your product, not a console where your own staff sign in to office apps, so the use case matters. Pricing is quoted and tied to usage, which makes early cost estimates harder. For SaaS teams that need enterprise SSO for customers, it is one of the cleanest developer options here.

WSO2 Identity Server is another open-source identity server, with a longer enterprise heritage than many community projects. It supports SSO, federation, access management, and API security, and it can be deployed on-premises or in a private cloud. Organisations that want source-code control without licence fees often shortlist it alongside Keycloak.

As with Keycloak, the work does not disappear: your team handles deployment, upgrades, and support unless you pay WSO2 for help. The admin experience is also more technical than a polished SaaS console. For engineering-led organisations with compliance or hosting constraints, that control is exactly the point.
