SonicWall NSa 6700 Network Security/Firewall Appliance

The SonicWall NSa 6700 is an enterprise-grade next-generation firewall (NGFW) designed for medium to large organizations that demand uncompromising security, scalable performance, and streamlined network management. Built on SonicWall’s Generation 7 architecture, the NSa 6700 delivers robust threat prevention, high-speed inspection of encrypted traffic, and flexible deployment options to protect data centers, campuses, and distributed networks. This appliance is engineered to handle modern threat landscapes with multi-layer defenses, including advanced intrusion prevention, application control, and real-time threat intelligence, all while maintaining predictable performance for critical business applications. With its scalable design, the NSa 6700 helps organizations consolidate security services in a single platform, reducing complexity and lowering total cost of ownership without compromising protection or reliability.

• Generation 7 architecture for unparalleled security – The NSa 6700 leverages SonicWall’s latest hardware and software architecture to deliver stateful inspection, flow-based processing, and dedicated acceleration for security services. This enables more effective containment of evolving threats while maintaining efficient performance as your network grows. Expect improved threat detection accuracy, faster policy enforcement, and tighter integration with SonicWall’s security services ecosystem to reduce dwell time for attackers across all network segments.
• High-performance throughput with scalable capacity – Designed to handle demanding workloads, the NSa 6700 provides strong firewall throughput and robust concurrent session handling. The platform is optimized for low latency, even under heavy SSL/TLS inspection, ensuring that business-critical applications such as ERP, CRM, and collaboration tools remain responsive. Its architecture supports scalable performance as traffic volumes increase, helping organizations keep pace with changing bandwidth demands without needing a hardware refresh each time.
• Comprehensive threat prevention and security services – Beyond dynamic firewall protection, the NSa 6700 includes integrated security services such as Intrusion Prevention System (IPS), gateway antivirus, content filtering, and application control. It also supports SSL/TLS inspection to reveal hidden threats in encrypted traffic and leverages real-time threat intelligence to block emerging exploits. With these multi-layer defenses, enterprises gain stronger protection against zero-day attacks, botnets, and targeted intrusions while maintaining user productivity and data security.
• Flexible deployment with high availability – The NSa 6700 is built for resilient, mission-critical networks. It supports deployment in data centers, campuses, and hybrid environments with options for high availability and clustering to ensure continuous protection even during maintenance or hardware failures. Redundant power and hot-swappable components further enhance reliability, while centralized management simplifies provisioning across multiple sites and allows synchronized policy enforcement.
• Unified management and streamlined operations – Manage security policies, traffic flows, and threat responses from a single console. The NSa 6700 integrates with SonicWall’s centralized management tools and cloud-based services for policy creation, monitoring, reporting, and automated updates. This cohesion reduces administrative overhead, accelerates incident response, and delivers consistent protection across distributed networks, remote sites, and mobile users.
