What is the purpose of secure web gateway (SWG) in FortiSASE?

The purpose of a secure web gateway (SWG) in FortiSASE is primarily to provide secure access to web applications while simultaneously protecting users from web-based threats. This is achieved through various functionalities that SWGs offer, such as URL filtering, malware detection, and inspection of web traffic. By analyzing outgoing and incoming web traffic, the SWG ensures that users can access web applications safely, reducing the risk of exposure to harmful content like malicious websites, phishing attacks, and other internet threats.

In contrast to filtering email traffic, which is not the primary role of an SWG, the focus is broader and oriented around securing web-related interactions. SWGs do not typically restrict all internet access, as such a measure would be counterproductive to enabling users to perform necessary online tasks. Lastly, an SWG is designed to enhance security without unnecessarily increasing the workload on users; rather, it streamlines and safeguards their internet usage. Hence, option A accurately reflects the comprehensive role of an SWG within FortiSASE.
