NSE7_SSE_AD-25 Exam Dumps : Fortinet NSE 7 - FortiSASE 25 Enterprise Administrator

The FortiSASE On/off-net detection feature is a two-part configuration designed to optimize bandwidth and user experience by determining when a device is in a trusted environment.

Rule Set Definition: The first part involves defining what constitutes an "on-net" or "on-fabric" status. In this scenario, the customer successfully configured a rule set named CERT-PUBLIC-IP using the Connects with a known public IP detection type. This tells FortiSASE that if the endpoint’s public WAN IP matches the corporate gateway, it is considered to be on the corporate network.

Profile Exemption Logic: Defining the rule set is not enough to stop the VPN connection. Within the Endpoint Profile (under the Connection tab > On/off-net Settings), there is a specific toggle labeled Exempt endpoint from FortiSASE auto-connect when endpoint is on-net (or in some versions, Bypass FortiSASE when endpoint is on-net).

Exhibit Analysis: Looking at the provided exhibit (image_57097d.jpg), the "Exempt endpoint from FortiSASE auto-connect..." toggle is clearly disabled (switched to the left).

Root Cause: Because this toggle is disabled, FortiClient identifies that it is "on-net" based on the IP rule, but it has no instruction to skip the VPN connection. Consequently, the "Automatically" initiate tunnel setting remains the dominant instruction, causing the VPN to connect regardless of the network location.

To resolve the issue, the administrator must enable the Exempt endpoint from FortiSASE auto-connect when endpoint is on-net option in the SASECert01 profile.

In a FortiSASE environment, the Unified FortiClient agent is the critical component that fulfills the requirement for "always-on" connectivity and security for remote users.

Persistent Encrypted Tunnels: The Unified FortiClient maintains a persistent, always-on connection to the FortiSASE infrastructure.4 This is typically achieved through an auto-connect VPN tunnel (SSL or IPsec) that initiates as soon as the user logs into their device and has internet access.

Continuous Security Enforcement: By staying connected to a nearby FortiSASE Point of Presence (PoP), the endpoint ensures that all traffic is inspected. This allows the organization to enforce a consistent security posture—including Web Filtering, Antivirus, and Application Control—regardless of whether the user is at home, in a coffee shop, or traveling.

Zero-Trust Integration: Beyond simple connectivity, the unified agent supports Universal ZTNA. It continuously verifies the identity of the user and the security posture of the device before granting access to specific applications, thereby satisfying modern zero-trust security mandates.

Comparison of Other Components:

SD-WAN on-ramp (B): Used primarily to integrate existing branch office SD-WAN networks with the SASE cloud for private application access.

Secure Web Gateway (C): While a feature of the SASE PoP, the agentless SWG deployment (using PAC files) does not provide the same level of "always-on" persistent tunnel protection as the FortiClient agent.

Thin-branch SASE extension (D): Focused on securing small branch locations (using FortiAP or FortiExtender) where individual client agents may not be deployed on every device.

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.
