The most valuable feature of the solution is that PingFederate is very customizable since it allows its user to write in Java while using Spring, allowing for any plugin for almost any place or entity inside of it. You can modify everything, and it's a very suitable tool, more than Okta or Azure AD when you have a non-standard structure since it allows for customization and runs as a separate solution or a service.

PingFederate is very flexible. We can do many customizations, and it also provides an SDK to tailor it to our specific requirements. There are also numerous plugins available. I've worked with tools like ForgeRock and Okta, but I find PingFederate to be the most customizable.

It provides basic SSO functionality, but we can easily extend it. For instance, if a client requires multi-factor authentication (MFA) beyond username and password, such as OTPs or knowledge-based answers, we can integrate those. 

Ultimately, we tailor the solution based on client needs. In fact, I've also worked in presales, demonstrating the capabilities of PingFederate through POCs (Proof of Concepts).

PingFederate gives you granular control over the settings. There are many options for fine-tuning policies. 

The most valuable feature is multifactor authentication.
