To meet the requirement of ensuring that emails received by company users that contain URLs do not make them susceptible to data loss from accessing malicious or undesired external content sources, the administrator must configure two features on Cisco Secure Email Gateway:
antispam scanning and URL filtering. Antispam scanning can block or quarantine messages that are identified as spam based on various criteria, such as sender reputation, message content, and message headers. URL filtering can rewrite or defang URLs in messages that are associated with malicious or undesirable websites, such as phishing, malware, adult, or gambling sites.
