Network Security

Block malware, prevent intrusions and control applications, for your entire network traffic, with our industry-leading firewall solutions.

Big Iron provides Dell SonicWALL solutions, one of the leading providers of next-generation firewalls (NGFWs).

The proven SonicOS firmware is at the core of every Dell SonicWALL NGFW. SonicOS leverages scalable, multi-core hardware architecture and single-pass, low latency. The Reassembly-Free Deep Packet Inspection® (RFDPI) engine scans all traffic regardless of port or protocol. SonicWALL NGFWs ensure that every byte of every packet is inspected while maintaining the high performance and low latency that busy networks require. Unlike other firewalls, the SonicWALL single-pass RFDPI engine enables simultaneous, multi-threat and application scanning, as well as analysis of any size file, without packet reassembly. This enables Dell SonicWALL NGFWs to massively scale to extend state-of-the-art security to growing and distributed enterprise networks.

Dell SonicWALL firewalls offer a range of robust capabilities, including:

Website/URL filtering (content filtering)
Deep packet inspection of SSL encrypted sessions (DPI-SSL)
Malware protection
Wireless security
Virtual private networking (VPN) over SSL or IPSec
Application intelligence, control and real-time visualisation
Stateful failover/failback
Intrusion prevention service
Multi Layered Security
