What is the primary function of a secure web gateway (SWG)?

The primary function of a secure web gateway (SWG) is to protect users from web-based threats and enforce security policies. This security device acts as a filter between users and the internet, ensuring that malicious content, such as malware or phishing attempts, is blocked before it can reach users. By analyzing web traffic in real-time, a SWG can enforce organizational policies regarding acceptable internet usage and provide comprehensive protection against various threats.

The implementation of security features within a SWG includes URL filtering, malware scanning, and data loss prevention, which collectively enhance the overall safety of web interactions for users. By focusing on both threat mitigation and policy enforcement, a SWG plays a crucial role in maintaining a secure network environment for both remote and on-premises users.

Other options misrepresent the primary role of an SWG. While enhancing internet speed could be a secondary benefit due to optimizations, it is not the main purpose. Providing unrestricted access contradicts the very reason SWGs exist, as they are designed to impose controls and maintain secure browsing. Lastly, serving as a backup for all web traffic does not capture the essential function of a secure web gateway, which focuses instead on inspection and protection rather than data redundancy.
