The firewalls will sport support for redundant configurations to ensure high availability and load balancing, along with better performance and scalability, said Barry Cioe, senior director of product management at Symantec.
The three models will each have four 10/100 Ethernet ports and will add proxies for protocols such as H.323 and RTSP (Real Time Streaming Protocol) used in Web conferencing, allowing them to support secure Web conferences.
The appliances will also feature enhanced proxies for longer-supported protocols such as HTTP (Hypertext Transfer Protocol) and SMTP (Secure Mail Transfer Protocol).
The VelociRaptor line will include support for the US government-approved Advanced Encryption Standard crypto-system, Cioe said. The firewalls are aimed at offices that have between 30 and 10,000 systems to protect, and offer up to 100M bps (bits per second) of throughput, he added.
The VelociRaptor 1100, the low-end model, is designed for networks of between 30 and 100 nodes, offer 60M bps of throughput and will cost $4,995 (£3,450).
The 1200 supports up to 250 nodes, can handle up to 100M bps of traffic and will carry a $9,995 (£6,900) price tag.
The high-end model, the VelociRaptor 1300, has no limit to the number of devices it can protect, performs at 100Mbps and will cost $14,995 (£10,354).
