Web Security Appliance (WSA)

WSA protects users from web-based threats by acting as a secure web gateway. It filters content, scans for malware, and enforces policies based on user identity, URL reputation, and web categories.

DLP and Encryption

Data Loss Prevention (DLP) technologies help prevent unauthorized sharing of sensitive information. Encryption ensures confidentiality of data in transit or at rest. Cisco's content security integrates both to prevent data exfiltration and enforce compliance.

# Example: Enabling encryption on email content
