What NETSCOUT Arbor Edge Defense is

NETSCOUT Arbor Edge Defense is an always-on, on-premises solution for protecting a network perimeter against DDoS attacks and other threats. It is deployed inline between an internet router and firewall, with appliance and virtual form factors available. Its stateless perimeter defenses target short-lived application-layer and state-exhaustion attacks that can affect applications and firewalls. Arbor Edge Defense can also block inbound scanning and brute-force attempts, communications with known malicious sites, and outbound command-and-control traffic from compromised devices. For networks using content delivery networks, it can address 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. Threat indicators can come from NETSCOUT’s ATLAS Intelligence Feed or third-party feeds. Administrators can selectively decrypt traffic for specific protected services, IP segments, or protection levels. Listed interfaces include REST API, STIX/TAXII, and Syslog, including CEF and LEEF formats. Arbor Enterprise Manager provides centralized deployment management, DDoS management, and reporting. A cloud-signaling feature can connect on-premises mitigation with Arbor Cloud for multi-vector attacks, including volumetric attacks. Pricing is on request; NETSCOUT says its solutions use hardened operating systems, regular updates, encrypted communications, a built-in firewall, and local or TACACS/RADIUS authentication.
