The correct answer is B. A direct security benefit of HTTPS Inspection is filtering malicious content inside encrypted traffic. Modern malware delivery, phishing, command-and-control activity, and file downloads often use HTTPS. If the gateway cannot inspect encrypted content, Threat Prevention, Anti- Virus, Threat Emulation, URL Filtering, and Application Control may have reduced visibility. Option A is partially related because URL Filtering can block sites, but site blocking is not the main technical benefit of HTTPS Inspection itself. Option C is wrong because bandwidth control is not the purpose of HTTPS Inspection. Option D is also only partially related: inspection can improve application visibility, but the stronger security answer is malicious-content filtering. HTTPS Inspection enables deeper inspection by decrypting traffic according to policy, applying security blades, and then re-encrypting traffic.
