NETSCOUT Arbor Edge Defense is an always-on, inline security solution deployed on premises between an internet router and firewall.
What NETSCOUT Arbor Edge Defense is
NETSCOUT Arbor Edge Defense is an always-on, inline security solution deployed on premises between an internet router and firewall. It provides stateless perimeter protection against short-lived application-layer and state-exhaustion DDoS attacks affecting applications and firewalls. The system can block inbound scanning and brute-force attempts, communications with known malicious sites, and outbound command-and-control traffic from compromised devices. For content-delivery-network deployments, it addresses direct-to-origin attacks and sources exploiting CDN proxies. AI-driven traffic analysis detects and classifies new attacks, recommends countermeasures, and can automatically mitigate them. Protection can use indicators from NETSCOUT’s ATLAS Intelligence Feed or third-party threat-intelligence feeds. Administrators can selectively decrypt traffic for chosen services, IP segments, or protection levels. Listed integrations include REST API, STIX/TAXII, and Syslog with CEF and LEEF formats. Arbor Enterprise Manager centralizes deployment, DDoS management, and reporting. Appliance and virtual form factors are available. Pricing is provided on request.
