Which is a Cisco solution feasures retrospective security?

AMP for Endpoints uses a retrospective security model, meaning it does not stop analysis at the point of initial file inspection. It continuously tracks file behavior over time, and if a file's disposition changes from clean to malicious based on new threat intelligence, AMP retroactively identifies all systems that encountered that file and provides an alert and trajectory. This continuous analysis distinguishes it from traditional point-in-time antivirus solutions.

Cisco Defense Orchestrator is a cloud-based policy management platform for simplifying firewall and VPN policy administration and does not provide retrospective malware analysis.

Cisco Umbrella is a DNS-layer security and SASE platform that blocks threats at the DNS level before a connection is established and does not perform retrospective file analysis.

Cisco Investigate (now Umbrella Investigate) is a threat intelligence and investigation tool used for researching domains and IPs, not for retrospective endpoint malware detection.
