Keycloak vs PingOne: Open Source vs Enterprise IAM Comparison

Keycloak and PingOne are two prominent solutions in the Identity and Access Management (IAM) space, each catering to different needs and environments. Keycloak is an open-source IAM solution, while PingOne is a fully managed, enterprise-grade IAM platform. In this post, we’ll dive into the specifics of both, compare their features, and provide practical guidance on when to choose one over the other.

What is Keycloak?

Keycloak is an open-source IAM solution that provides a comprehensive set of features for managing identities and access controls. It supports Single Sign-On (SSO), user federation, role-based access control, and integrates with various protocols like OAuth 2.0 and OpenID Connect. Keycloak is highly customizable and extensible, making it suitable for organizations looking for flexibility and control over their IAM infrastructure.

What is PingOne?

PingOne is an enterprise-grade IAM platform offered by Ping Identity. It provides a unified identity management solution that includes SSO, multi-factor authentication (MFA), and secure access management. PingOne is fully managed, meaning it handles all the operational aspects, allowing organizations to focus on their core business. It supports a wide range of identity providers, including social logins and enterprise directories.

Keycloak vs PingOne: Feature Comparison

Let’s break down the key features of both solutions to understand their strengths and weaknesses.

Authentication Protocols

Both Keycloak and PingOne support standard authentication protocols like OAuth 2.0, OpenID Connect, and SAML. However, PingOne also offers additional protocols such as WS-Federation and Kerberos, which might be necessary for legacy systems.

Multi-Factor Authentication (MFA)

PingOne provides robust MFA options out-of-the-box, including push notifications, SMS, voice calls, and hardware tokens. Keycloak also supports MFA, but it requires additional configuration and plugins.

User Federation

Keycloak excels in user federation, allowing you to connect to external identity providers like LDAP, Active Directory, and social logins. PingOne supports similar capabilities but with a more streamlined setup process due to its managed nature.

Customization and Extensibility

Keycloak is highly customizable and extensible, offering a rich set of APIs and SPIs (Service Provider Interfaces) for extending its functionality. This makes it a great choice for organizations with unique requirements. PingOne is less customizable but provides pre-built integrations and connectors for common use cases.

Scalability and Performance

PingOne is designed to scale globally and handle large volumes of users and transactions. Its fully managed nature ensures high availability and performance. Keycloak can be scaled horizontally, but it requires more effort in terms of infrastructure management.

Cost

Keycloak is free to use under the Apache License 2.0, making it a cost-effective option for small to medium-sized organizations. PingOne is a paid service, with pricing based on the number of users and features used. However, it eliminates the need for on-premises infrastructure costs.

Implementing Keycloak

Let’s walk through the process of implementing Keycloak for a simple SSO setup.

Step-by-Step Guide

Example Configuration

Here’s an example of configuring a client in Keycloak using the REST API.

curl -X POST \
  http://localhost:8080/auth/admin/realms/myrealm/clients \
  -H 'Authorization: Bearer <admin-token>' \
  -H 'Content-Type: application/json' \
  -d '{
    "clientId": "myclient",
    "rootUrl": "http://myapp.example.com",
    "publicClient": true,
    "redirectUris": [
      "http://myapp.example.com/*"
    ],
    "protocol": "openid-connect"
  }'

Implementing PingOne

Now, let’s explore the steps to implement PingOne for a similar SSO setup.

Step-by-Step Guide

Example Configuration

Here’s an example of creating an application in PingOne using the API.

curl -X POST \
  https://api.pingone.com/v1/environments/<environment-id>/applications \
  -H 'Authorization: Bearer <api-token>' \
  -H 'Content-Type: application/json' \
  -d '{
    "name": "My Application",
    "description": "SSO application for myapp.example.com",
    "enabled": true,
    "oidcApplication": {
      "grantTypes": ["AUTHORIZATION_CODE"],
      "responseTypes": ["CODE"],
      "homePageUrl": "http://myapp.example.com",
      "redirectUris": ["http://myapp.example.com/callback"],
      "logoutUrls": ["http://myapp.example.com/logout"]
    }
  }'

Security Considerations

Both Keycloak and PingOne offer strong security features, but there are some critical points to consider.

Securing Client Secrets

Always store client secrets securely, using environment variables or secure vaults. Avoid hardcoding them in your application code.

Data Encryption

Ensure that all sensitive data is encrypted both in transit and at rest. Use HTTPS for communication and enable encryption options in your database configurations.

Regular Updates

Keep your IAM solution up to date with the latest patches and updates to protect against vulnerabilities. Monitor security advisories and release notes for both Keycloak and PingOne.

Monitoring and Auditing

Implement logging and monitoring to track access and changes. Regularly review audit logs to detect and respond to suspicious activities.

Choosing Between Keycloak and PingOne

The decision between Keycloak and PingOne depends on your organization’s specific needs and constraints. Here are some factors to consider:

Budget

Keycloak is free to use, making it an attractive option for budget-conscious organizations. PingOne is a paid service, but it eliminates the need for on-premises infrastructure costs.

Customization Needs

If you have unique requirements and need extensive customization, Keycloak might be the better choice. PingOne offers pre-built integrations and connectors, but it’s less customizable.

Operational Overhead

Keycloak requires more effort in terms of infrastructure management and maintenance. PingOne is fully managed, reducing operational overhead and allowing you to focus on your core business.

Scalability Requirements

PingOne is designed to scale globally and handle large volumes of users and transactions. Keycloak can be scaled horizontally, but it requires more effort in terms of infrastructure management.

Security Requirements

Both solutions offer strong security features, but PingOne provides additional security options like advanced MFA and automated threat detection. If security is a top priority, PingOne might be the better choice.

Conclusion

Keycloak and PingOne are both powerful IAM solutions, each with its own strengths and weaknesses. Keycloak offers flexibility and customization at a lower cost, while PingOne provides a fully managed, enterprise-grade solution with robust security features. By understanding the differences and considering your organization’s specific needs, you can make an informed decision that aligns with your goals and requirements.
