What NSE7_SSE_AD-25 Questions and Answers feature?

FortiSASE is designed as a unified, single-vendor solution that specifically targets the convergence of networking and security to address the modern challenges of a distributed enterprise.2

Multicloud and SaaS Adoption: FortiSASE addresses the surge in cloud-first strategies by providing Next-Generation Dual-Mode CASB (Cloud Access Security Broker).3 This feature uses both inline and API-based inspection to provide comprehensive visibility into sanctioned and unsanctioned SaaS applications (Shadow IT), ensuring that data is protected regardless of whether it resides in AWS, Azure, Google Cloud, or SaaS platforms like Microsoft 365.

Hybrid Workforce: To support a workforce that moves between the home, the office, and public spaces, FortiSASE delivers consistent security posture.5 It replaces the inconsistent experience of legacy VPNs with a geographically dispersed network of over 150 Points of Presence (PoPs), ensuring low-latency access to applications while maintaining high-performance SSL inspection and threat detection for all remote users.

Zero Trust Integration: Central to the FortiSASE architecture is Universal ZTNA (Zero Trust Network Access).7 Unlike traditional VPNs that grant broad network access, ZTNA applies the principle of "never trust, always verify". It grants access on a per-session, per-application basis, continuously verifying the device posture and user identity before and during application access.9 This shift from implicit to explicit trust significantly reduces the internal attack surface and mitigates the risk of lateral movement by attackers.

By integrating these components into a single operating system (FortiOS) and managed via a single console, FortiSASE simplifies IT operations while delivering the visibility and control required for today's multicloud and hybrid environments.

In the FortiSASE architecture, there are two primary methods for delivering Secure Internet Access (SIA): Agent-based (using FortiClient) and Agentless (using Secure Web Gateway/SWG).

Use Case Analysis: The scenario describes a contractor—an unmanaged user—who requires temporary access for a web-based application (the POS system). For contractors or guests using personal/non-corporate devices where installing the FortiClient agent is either not feasible or not desired, FortiSASE provides the SIA Agentless deployment model.

Mechanism (SWG & PAC): In this mode, FortiSASE functions as an explicit web proxy. To steer the contractor's web traffic (HTTP/HTTPS) to the SASE cloud for inspection, the administrator provides the user with a proxy auto-configuration (PAC) file. The contractor simply configures their browser or operating system to point to the URL of this PAC file.

Security Enforcement: Once the PAC file is applied, all web traffic from the contractor's device is redirected to the FortiSASE SWG PoP. Here, the traffic is subject to the organization’s full security stack, including SSL deep inspection, Antivirus, Web Filtering, and Application Control, ensuring that even temporary contractor access is fully secured and logged.

Why other options are incorrect:

Option B (Tunnel Policy): This refers to agent-based access where a VPN tunnel is established. This requires FortiClient, which is generally not used for temporary contractors on unmanaged devices.

Option C (ZTNA Unmanaged): While ZTNA supports agentless access to private applications (SPA), providing internet access (SIA) to an unmanaged endpoint is specifically the role of the SWG/Proxy service.

Option D (Self-registration): While FortiSASE has a User Portal for onboarding, it is a method for user registration/credential management, not the technical traffic-steering mechanism used to provide internet connectivity.

According to the FortiSASE 25 Secure Internet Access Architecture Guide, the SWG (Agentless) approach is the recommended best practice for securing web-only traffic from unmanaged endpoints and third-party contractors.

Zero Trust Network Access (ZTNA) private access provides the most efficient and secure method for remote users to access a TCP-based application hosted on a private web server. ZTNA ensures that only authenticated and authorized users can access specific applications based on predefined policies, enhancing security and access control.

Zero Trust Network Access (ZTNA):

ZTNA operates on the principle of "never trust, always verify," continuously verifying user identity and device security posture before granting access.

It provides secure and granular access to specific applications, ensuring that remote users can securely access the TCP-based application hosted on the private web server.

Secure and Efficient Access:

ZTNA private access allows remote users to connect directly to the application without needing a full VPN tunnel, reducing latency and improving performance.

It ensures that only authorized users can access the application, providing robust security controls.
