GuardianKey for KeyCloak/RH-SSO

Painless authentication protection for your Single-Sign-On System.
Free native extension for KeyCloak and RH-SSO.

How the extension works

The GuardianKey extension for KeyCloak/RH-SSO sends events to the GuardianKey engine on each login attempt.

GuardianKey returns a risk level and a suggested action (ACCEPT, NOTIFY, HARD-NOTIFY, or BLOCK).

KeyCloak/RH-SSO or GuardianKey can notify your users about accesses in their accounts. Also, high-risk attempts can be blocked.

Notified users can tell if the attempts were legitimate or not. In the affirmative case, GuardianKey learns for future analysis, otherwise, your security team can be notified.
