Prisma SaaS, as a Cloud Access Security Broker (CASB), primarily uses a direct, API-based integration to connect with sanctioned SaaS applications. This out-of-band connection allows Prisma SaaS to scan data at rest, monitor user activity, and analyze sharing permissions directly within the SaaS environment. By leveraging the application provider's APIs, it gains deep visibility and can enforce Data Loss Prevention (DLP) and threat detection policies without being in the direct path of user traffic. This method is essential for discovering and remediating risks in data that already exists within the application.

A. Prisma SaaS is designed to secure cloud-based SaaS applications, not internal, on-premises services like print and file servers.

B. This is incorrect. Sanctioned applications are a primary source of risk for data leakage and threats, which is precisely why a CASB like Prisma SaaS is needed to provide additional security.

C. This describes a function of a Secure Web Gateway (SWG), such as that found in Prisma Access, not the primary mechanism of Prisma SaaS for protecting sanctioned applications.

"How It Works" section. The document states

"Prisma SaaS directly integrates with SaaS applications to provide visibility

data loss prevention

and threat prevention... API-based security for sanctioned SaaS applications provides detailed visibility and granular control over data and user activity." This directly supports the mechanism described in option D.

"Prisma SaaS" section. The guide explains

"Prisma SaaS is a multi-mode cloud access security broker (CASB) service that enables you to govern sanctioned SaaS application usage across your organization... It connects directly to sanctioned SaaS applications via APIs to scan for risks in data at rest and in transit." This confirms the direct API connection for sanctioned applications.

Reference: Chapter: "Get Started with Prisma SaaS

" Section: "Onboard SaaS Applications." The guide details the process of connecting Prisma SaaS to applications like Microsoft 365

which involves authorizing Prisma SaaS to access the application's data via its native APIs

demonstrating the direct connection model.
