NETASQ IPS-Firewalls have been built around a unique real-time intrusion prevention technology: ASQ (Active Security
Qualification). ASQ provides context-based intrusion prevention by analyzing traffic from network up to application layer, while applying
multiple methods to identify and block malicious traffic. ASQ uses classes of attacks guaranteeing superior accuracy to protect against
zero-day threats at wire speeds of up to 1.5 Gbps. This unique concept, linked to hardware specifically designed to provide next-
generation intrusion prevention, allows NETASQ IPS-Firewalls to provide real-time application layer intrusion prevention without
degrading system performance.
