SSO Solutions: Top 10 SSO Providers You Must Consider in 2024

How Do Single Sign-On Solutions Work?

Single Sign On (SSO) providers allow companies to use trusted third-parties to authenticate users to multiple systems using one set of credentials. SSO solutions handle all authentication activities and save valuable development time, because there is no need for a proprietary authentication system for each application.

Let’s look at things from the perspective of the end-user. Once the user has logged into an application successfully, they can access all applications registered with the single sign-on (SSO) tool. Furthermore, SSO tools can be used with multiple protocols – Security Assertion Markup Language (SAML), OpenID Connect, and more.

As shown in the illustration above, the initial action is checking for SSO cookies. When it’s a first time login, there is no SSO cookie. The user then utilizes one of the predefined login methods, following which an SSO cookie (with an expiry date) is created for future use. The user can then proceed to using the application with minimal fuss.

Main benefits of using SSO platforms include:

  • Ease of use for end-users, which enhances customer satisfaction
  • Less stress on developers to create new authentication solutions
  • Improved security and compliance capabilities
  • A seamless experience that is easy to integrate
  • Better and easier to manage, especially while scaling up fast

How to Choose an SSO Solution: Key Considerations

Here are the main things to consider when selecting an SSO solution:

Compatibility with Existing Infrastructure

An SSO solution must work seamlessly with your current systems, applications, and platforms. It should also support the various authentication protocols used by your systems, such as SAML (Security Assertion Markup Language), OIDC (OpenID Connect), or OAuth (Open Authorization).

Consider the technical requirements of the solution. Does it require specific hardware or software? Does it need any changes to your network configuration? Can it integrate with your current identity providers, such as Active Directory or LDAP (Lightweight Directory Access Protocol)? An SSO solution that aligns with your existing infrastructure will ensure a smooth and efficient implementation process.

Security Standards and Compliance

Security is a critical aspect of any SSO solution. The solution must adhere to the highest security standards to protect your systems and data from breaches. It should use strong encryption algorithms to secure the exchange of tokens and should offer robust mechanisms for authenticating users, such as multi-factor authentication.

In addition to security standards, the SSO solution must also comply with the various regulatory requirements applicable to your industry. For instance, if you operate in the healthcare sector, the solution must comply with HIPAA (Health Insurance Portability and Accountability Act) regulations. Similarly, if you deal with credit card information, the solution must adhere to PCI DSS (Payment Card Industry Data Security Standard) requirements.

End-User Experience

A good SSO solution should enhance the user experience, not complicate it. Users should be able to log in to their applications quickly and easily, without having to remember multiple passwords or go through complex authentication processes. The solution should also offer a seamless transition between different applications, ideally without requiring the user to log in again.

In addition to ease of use, the solution should also provide users with control over their accounts and data. They should be able to manage their credentials, update their information, and monitor their account activities. A solution that prioritizes user experience will not only improve productivity but also increase user satisfaction and acceptance.

Scalability and Performance

Scalability and performance are key considerations for any SSO solution. The solution must be able to handle the growing number of users and applications supported by your product or organization. It should also deliver high performance to ensure that the authentication process does not slow down the user’s access to their applications.

Consider the solution’s capacity to handle peak loads, such as during the start of a workday when many users are logging in simultaneously. Also, evaluate the solution’s ability to scale horizontally (by adding more servers) or vertically (by increasing the capacity of existing servers). A scalable and high-performing SSO solution will ensure that your organization’s productivity is not hampered by system slowdowns or downtime.

Customization and Flexibility

Lastly, consider the customization and flexibility offered by the SSO solution. Can it be tailored to meet the specific needs of your organization? Can it adapt to changes in your business processes or IT environment? Can it accommodate new applications or platforms as your organization grows and evolves?

A good SSO solution should offer a high degree of customization and flexibility. It should allow you to define your own authentication policies, customize the user interface, and integrate with a wide range of applications and platforms. It should also be flexible enough to adapt to changes, whether they are due to business growth, technological advancements, or regulatory updates.
