How the Prisma Access Browser Extension Works
PABX initiates a login attempt every few minutes or when it detects a
change in the existing IdP session cookie. The process includes the following
steps:
IdP session Detection: When a user signs in to a business
application (such as a CRM) that integrates with their IdP, the browser
receives a session cookie that confirms the active session.
Active session Verification: During each login attempt, Prisma Access Browser Extension checks for valid session cookies from supported
IdPs.
Domain Matching: If Prisma Access Browser Extension detects an
active session, it checks whether the user’s domain (for example,
company.com in user@company.com)
exists in the PABX loginDomains configuration.
Silent Background Login: If the domain matches, Prisma Access Browser Extension silently attempts to authenticate in the
background by accessing a configured Prisma Access Browser application that
integrates with the IdP. This typically occurs when you set up the Cloud
Identity Engine (CIE) during on-boarding.
- Local Session Establishment: After successful authentication, Prisma Access Browser Extension creates a local session and enforces policy rules
associated with the logged-in user.
By using single sign-on (SSO), Prisma Access Browser Extension enables users
to access multiple systems through a single login. This reduces sign-in effort and
improves security by centralizing credential management at the IdP level.
