Splunk Cloud SAML integration

Multi-factor authentication (MFA) is an extra layer of security used when logging into websites or apps to authenticate users through more than one required security and validation procedure that only you know or have access to.

Security Assertion Markup Language (SAML) is a protocol for authenticating to web applications. SAML allows federated apps and organizations to communicate and trust one another’s users.

Arculix™, as a SAML provider, improves the user login experience for Splunk Cloud users with smart and convenient single sign-on (SSO) MFA.

Prerequisites

  • Arculix account with a configured Identity Provider and LDAP Agent.

    For more information, see the Arculix LDAP Agent deployment guide.

  • User account with administrative privileges for Arculix.

  • Splunk Cloud user account with administrative access.
