4. Deployment Options

The SonicWall NSA 2700 offers flexible deployment options suitable for various network architectures, particularly for medium and distributed enterprises.

4.1 Internet Edge Deployment

In this standard deployment, the SonicWall NSA 2700 protects private networks from malicious traffic originating from the internet. This setup allows for:

• Deployment of a Next-Generation Firewall (NGFW) solution with high performance and port density, including 10 GbE connectivity.
• Visibility and inspection of encrypted traffic, including TLS 1.3, to block evasive threats without compromising performance.
• Integrated security features such as malware analysis, cloud app security, URL filtering, and reputation services.
• Reduced complexity and increased efficiency through central management and an intuitive user interface.

4.2 Medium and Distributed Enterprises Deployment

The NSA 2700 supports SD-WAN and can be centrally managed, making it suitable for medium and distributed enterprises. This deployment model enables organizations to:

• Future-proof against evolving threat landscapes with multi-gigabit threat analysis performance.
• Provide direct and secure internet access to distributed branch offices, avoiding back-hauling through corporate headquarters.
• Allow distributed branch offices to securely access internal resources in corporate headquarters or public clouds, improving application latency.
• Automatically block threats using encrypted protocols like TLS 1.3, securing networks from advanced attacks.
• Leverage high port density, including 10 GbE connectivity, to support distributed enterprise and wide area networks.

5. Key Technologies

5.1 Reassembly-Free Deep Packet Inspection (RFDPI)

The SonicWall Reassembly-Free Deep Packet Inspection (RFDPI) engine is a single-pass, low-latency inspection system. It performs stream-based, bi-directional traffic analysis at high speed without proxying or buffering. This technology effectively uncovers intrusion attempts and malware downloads across Layers 3-7, even when applying to encrypted traffic like TLS/SSL. RFDPI neutralizes evasion techniques by normalizing and decrypting network streams, then analyzing them against multiple signature databases for threats.

5.2 Secure, High-speed Wireless

The NSA 2700 can be combined with a SonicWall 802.11ac Wave 2 wireless access point (e.g., SonicWave 432i) to create a high-speed wireless network security solution. Both NSA series firewalls and SonicWave access points feature 2.5 GbE ports, enabling multi-gigabit wireless throughput. The firewall scans all wireless traffic for malware and intrusions, even over encrypted connections. Additional security features like content filtering, application control, and Capture Advanced Threat Protection can be applied to the wireless network.
