SonicWall NSa 4700 Secure Upgrade Plus Firewall

The SonicWall NSa 4700 is a next-generation firewall engineered for mid-to-large enterprise environments, delivering high-throughput threat prevention across campus perimeters and data-center edge deployments. Built on SonicWall's seventh-generation hardware platform and powered by a multi-core architecture, the NSa 4700 provides deep packet inspection without sacrificing throughput, sustaining firewall performance of up to 18 Gbps and threat-prevention throughput of 4.2 Gbps. The appliance supports SonicWall's Real-Time Deep Memory Inspection (RTDMI) and Reassembly-Free Deep Packet Inspection (RFDPI) engines, enabling simultaneous scanning of encrypted and unencrypted traffic streams with minimal latency impact on production workloads.

A distinguishing capability of the NSa 4700 is its TLS/SSL inspection throughput of 4.0 Gbps, addressing the growing enterprise challenge of encrypted traffic blind spots without creating network bottlenecks. The platform handles up to 3,000,000 maximum connections and supports 120,000 new connections per second, making it well-suited for dense user environments and east-west data-center traffic. The appliance ships with an integrated 10 GbE and 2.5 GbE port mix, providing flexible high-speed connectivity for redundant uplinks, aggregated server segments, and multi-zone security architectures.

The NSa 4700 is offered under SonicWall's Secure Upgrade Plus program (part number 02-SSC-9468), which bundles the appliance with an Advanced Protection Service Suite (APSS) subscription covering Capture ATP sandboxing, Gateway Anti-Virus, Anti-Spyware, Intrusion Prevention, Application Control, Content Filtering, and 24×7 support for the subscription term. This packaging model simplifies procurement planning for enterprise security teams seeking a single-SKU solution that covers both hardware refresh and ongoing threat intelligence services, and it is particularly relevant for organizations migrating from legacy SonicWall platforms to current-generation hardware.

Ideal for

• Campus perimeter firewall providing full threat-prevention inspection for 1,000–5,000 concurrent users without degrading application performance
• Data-center edge enforcement point for east-west microsegmentation and north-south encrypted traffic inspection in hybrid on-premises environments
• Encrypted traffic visibility layer for organizations with high TLS 1.3 adoption, enabling compliance-driven deep inspection of HTTPS, SMTPS, and other SSL-wrapped protocols
• Consolidated branch aggregation hub terminating multiple SD-WAN or VPN tunnels from distributed regional offices into a central high-availability pair
• Regulatory compliance enforcement boundary for PCI-DSS, HIPAA, or NIST-aligned segments requiring granular application control, IPS, and detailed logging
• Legacy appliance refresh target for enterprises running end-of-support SonicWall NSa 4600 or NSa 4650 hardware seeking a direct throughput and capacity upgrade on the same management platform
