About The SSO Wall of Shame

The SSO Wall of Shame is a public list of software vendors that treat single sign-on as a luxury feature, not a core security requirement. Each listed vendor is shown with its base plan price, its SSO price and the percentage increase between them. The site also explains SSO, which lets a team log in once to reach all its applications, and argues that SSO should be included in all plans or offered for a reasonable charge.

Pricing is not clearly stated.
