What is the primary benefit of blocking password-protected and unscannable content?

Blocking password-protected and unscannable content primarily serves the purpose of preventing the download of potentially harmful content. This is crucial in maintaining network security, as such content can hide malware or other security threats that are not identifiable by security systems. When files are password-protected or unscannable, they bypass standard security checks, increasing the risk of introducing harmful software into the organization’s environment. By restricting access to these types of content, organizations can significantly reduce their vulnerability to cyber threats, ensuring a safer and more secure digital workspace for users.

The other choices focus on aspects such as downloading speed or unrestricted access, which do not address the core security issue presented by unscannable or password-protected files. Ensuring security and data integrity through content filtering is a fundamental aspect of network administration in modern IT environments.
