The SonicWall Network Security services platform (NSsp) 12000 series takes a modern approach to threat detection and prevention by combining cloud intelligence with appliance-based protection in a scalable, high-speed platform. Designed for large distributed enterprises, data centers and service providers, NSsp series next-generation firewalls (NGFWs) leverage innovative deep learning security technologies in the Capture Cloud Platform to deliver proven protection from the most advanced threats without slowing performance.


Features & Benefits

Advanced Threat Protection

Stop Zero-Day and unknown malware in its tracks with Real-Time Deep Memory Inspection (RTDMI™) and Reassembly-Free Deep Packet Inspection (RFDPI). Pair robust on-box technology with cloud-based updates to stay ahead of the threats.

Multi-Instance Firewall

Take a modern approach to legacy multi-tenancy with Multi-Instance using containerized architecture. Run multiple independent firewall instances, software versions, and configurations on the same hardware without managing multiple appliances.

Unified Policy for Modern Enterprises

Unified Policy allows administrators to combine Layer 3 to Layer 7 access and security rules into a single policy to reduce rule management overhead. Intuitive policy creation and visual workflow reduce configuration errors and deployment time for a better overall security posture.

Scalability and Availability

With multiple configuration options and easy deployment build a security perimeter that will grow with you. Keep your business up and safe from threats to your network and beyond with redundant power supplies, fans and a built-in storage module to store logs, reports, firmware backup files and more.

High-Speed Performance

Featuring high port density and multiple 100/40/10 GbE interfaces, process several million simultaneous encrypted and unencrypted connections with unparalleled threat prevention technology. Get more from your investment as resource utilization and connection requirements grow with the explosion of connected devices and users.
