In basic terms, a proxy is a networking function, while an SWG is a security solution. Typically, a proxy is a dedicated computer, or app, that is positioned between a remote user and an online destination, such as a website, server, or cloud-based app. An SWG is also positioned between the user and his/her intended target, but its functionality is much broader and more targeted — monitoring in real time for web-based threats such as malware, phishing attempts, and other malicious activities, and using tactics that can include URL filtering, virus/malware scanning, SSL inspection, and content filtering.
