Why Use SAML?


One-click access from portals or intranets, deep linking, password elimination and automatically renewing sessions make life easier for the user.


Based on strong digital signatures for authentication and integrity, SAML is a secure single sign-on protocol that the largest and most security conscious enterprises in the world rely on.

Open Source Standards Base

SAML is based on a standard, which ensures interoperability across identity providers and gives enterprises the freedom to choose a vendor.

Phishing Prevented

If you don't have a password for an app, you can't be tricked into entering it on a fake login page.

It's Friendly

SAML simplifies life for IT because it centralizes authentication, provides greater visibility, enables the provisioning of users in and out of applications and cuts down on password resets and help desk tickets.
