Quick Answer
The answer is Web mode. This is the correct choice because Web mode provides clientless access through a standard browser, using the FortiGate’s SSL VPN web portal as a reverse proxy to translate HTTPS requests from the user to internal application servers, eliminating the need for any client software installation. On the Fortinet NSE 7 Advanced Security NSE7 exam, this question tests your understanding of SSL VPN deployment modes, often appearing alongside tunnel mode as a distractor; a common trap is confusing Web mode with tunnel mode, which requires a client and full network-layer access. To remember, think of “Web” as “browser-only”—no client, no install, just a portal. A useful mnemonic is “W for Web, W for Without client.”
This NSE7 practice question tests your understanding of advanced vpn and zero trust. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrator is configuring SSL VPN on FortiGate and wants to allow users to access internal applications via a web portal without installing any client software. Which SSL VPN mode should be used?
DTLS
Why wrong: DTLS is a transport protocol to improve performance, not a mode.
Tunnel mode
Why wrong: Tunnel mode requires the FortiClient software to be installed.
Web mode
Web mode provides clientless access through a web portal.
Split tunneling
Why wrong: Split tunneling is a routing configuration, not a VPN mode.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Web mode
Web mode (option C) is correct because it enables users to access internal web applications through a FortiGate SSL VPN web portal using only a standard browser, with no client software installation required. The portal acts as a reverse proxy, translating HTTPS requests from the client to the internal application servers, making it ideal for clientless remote access.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
DTLS
Why it's wrong here
DTLS is a transport protocol to improve performance, not a mode.
Tunnel mode

Split tunneling
Why it's wrong here
Split tunneling is a routing configuration, not a VPN mode.
Common exam traps
The trap here is confusing 'Web mode' with 'Tunnel mode' because both are SSL VPN features, but only Web mode provides clientless access via a browser portal, whereas Tunnel mode always requires the FortiClient software to be installed.
Detailed technical explanation
In Web mode, the FortiGate acts as an HTTPS reverse proxy, terminating the SSL/TLS connection from the client and then initiating a separate connection to the internal web server. This allows the FortiGate to inspect and rewrite URLs, cookies, and embedded links in the HTML content to ensure seamless navigation, while also enforcing security policies such as client certificate authentication or SAML-based SSO. A real-world scenario is providing access to a corporate SharePoint or ERP system for contractors who cannot install VPN clients on their personal devices.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the NSE7 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
