Smarter DDoS Security at Scale

NETSCOUT introduced Arbor Edge Defense (AED), a selective decryption solution that inspects only suspicious encrypted traffic to mitigate DDoS attacks hidden in TLS 1.3 sessions. Traditional full‑traffic decryption is resource‑intensive, creating blind spots for security teams. AED combines known‑source blocking, TLS handshake analysis, TCP limiting, and rate‑based protections, leveraging the ATLAS Intelligence Feed to drop malicious flows before decryption. The approach preserves bandwidth and scales to high‑volume traffic while allowing customizable decryption policies.
