FortiNDR

Why do you need FortiNDR?

93% of malware hides in encrypted traffic. Traditional IDS/IPS requires SSL decryption, which is costly and not always possible. SOC teams drown in alerts, lacking time for threat hunting and correlation.

FortiNDR is an AI-powered Network Detection & Response that analyzes encrypted traffic without decryption using JA3/JA3S fingerprinting. Virtual Security Analyst automatically correlates alerts and maps to MITRE ATT&CK, reducing alert fatigue.
