NSa series firewalls feature a multi-core hardware architecture that utilizes specialized security microprocessors. When organizations activate deep packet inspection functions such as intrusion prevention, anti-virus, anti spyware, TLS/SSL decryption/inspection and others on their firewalls network performance often slows down, sometimes dramatically. Inclusion and exclusion rules allow total control to customize which traffic is subjected to decryption and inspection based on specific organizational compliance and/ or legal requirements. It looks deep inside every packets (the header and data part) searching for protocol non-compliance, threats, zero-days, intrusions, and even defined criteria to detect and prevent hidden attacks that leverage cryptography, block encrypted malware downloads, cease the spread of infections, and thwart command and control (C&C) communications and data exfiltration. Going beyond intrusion prevention, anti-malware and web filtering, SonicWall NGFWs provide a further level of protection by performing full decryption and inspection of TLS/SSL and SSH encrypted traffic as well as non-proxyable applications, enabling complete protection regardless of transport or protocol. The security architecture in SonicWall NGFWs has been validated as one of the industry’s best for security effectiveness by NSS Labs which awarded SonicWall its “Recommended” rating for the fourth consecutive year. Unlike other security products that cannot inspect large files for hidden threats, NSa firewalls scan files of any size across all ports and protocols. The NSa series leverages on-box capabilities including intrusion prevention, anti-malware and web/URL filtering in addition to cloud-based services such as CloudAV and SonicWall Capture multi-engine sandboxing to block zero-day threats at the gateway. Our patented single-pass RFDPI threat prevention engine examines every byte of every packet, inspecting both inbound and outbound traffic simultaneously. NSa series next-generation firewalls (NGFWs) integrate a series of advanced security technologies to deliver a superior level of threat prevention. Superior threat prevention and performance
