Which two mechanisms does Cisco Threat Defense use to gain visibility into high-risk cyber threats?

Cisco Threat Defense (FTD) leverages file reputation and traffic telemetry to identify high-risk threats. File reputation services analyze file characteristics and known threat intelligence databases to determine if a file is malicious. Traffic telemetry involves collecting and analyzing network flow data and metadata to detect anomalies, suspicious patterns, and indicators of compromise that signify malicious activity. Virtual private networks (VPNs) provide secure connectivity but don't inherently offer threat visibility. VLAN segmentation isolates network traffic but isn't a threat detection mechanism itself. Dynamic enforce policy is a security control, not a visibility mechanism.
