What is the primary function of a secure web gateway?

The primary function of a secure web gateway is to filter and inspect web traffic for threats. This involves various security measures such as blocking malware, phishing attempts, or unauthorized access to harmful websites. A secure web gateway acts as a barrier between internal networks and the internet, ensuring that any data entering or leaving the organization's network is safe and in compliance with company policies.

By inspecting web traffic, the secure web gateway safeguards against a multitude of cyber threats and helps maintain the integrity of the organization's data. Additionally, it often provides visibility into user activity and helps enforce security policies, enabling organizations to respond to threats in real-time.

The other options do not accurately reflect the core role of a secure web gateway. For instance, providing unlimited internet access goes against the fundamental purpose of security by exposing users to potential threats. Monitoring employee productivity may be a secondary benefit, but it is not the primary function of a secure web gateway. Likewise, increasing overall network speed is not a goal of this technology; in fact, the filtering process could introduce some latency, though it is necessary for enhanced security. Thus, the true and essential function of a secure web gateway lies in its ability to filter and inspect web traffic for threats.
