FortiGate 620B-DC Network Security Appliance answers the call of growing enterprise networks by integrating a purpose-built security processing ASIC, known as the FortiASIC Network Processor, designed to deliver security throughput at switching speeds. Sixteen hardware accelerated interfaces (expandable to 20) allow networks to enforce firewall policy between network segmentation points for layered security with switch-like performance. An additional purpose-built ASIC, known as the FortiASIC Content Processor, provides additional acceleration for content intensive security technologies such as intrusion prevention and antivirus scanning for dangerous traffic streams. The inclusion of an Advanced Mezzanine Card (AMC) expansion slot allows for even more flexibility, offering additional ASIC-accelerated ports for additional throughput or disk-based storage for local logging and content archiving.
