As firewalls go, the CyberGuard SL3200 is a monster: a huge, noisy beast with performance that matches its rugged looks. The name denotes its capacity - 3.2 gigabits of total throughput, shared among a maximum of 26 Ethernet ports. Even more notably, it is able to multiplex several interfaces into a small number of very high-capacity pipes, all secured at wire speed.
Designed for high-demand environments, the box has all the HA features you'd expect - hot-swappable fans and power supplies, as well as RAID 5 storage, with an internal layout designed for maximum airflow and heat dissipation. Fail-over between two boxes is available if you have an extended license.
CyberGuard has a long and impressive track record in the firewall market, providing solutions from the desktop to those suitable for the high end, such as data centers. The SL2000 is positioned at the high end and, while certainly not the cheapest firewall in this Group Test, is worth every penny.
CyberGuard offers a range of firewall/VPN appliances with specifications ranging from three Ethernet interfaces and 125Mbits/ sec throughput to 21 Ethernet interfaces and 2Gbits/sec throughput. All have an integrated VPN, run the same firewall software, and have the same configuration GUI. We tested model KS1500, which can have up to 18 Ethernet interfaces, of which two are gigabit-over-copper as standard.
Performance is the strength of the KS1500, which is designed to cope with 1.5 Gbits/sec throughput and up to 1.2 million simultaneous connections. The firewall boasts a host of certification standards including Common Criteria Eval uation Assurance Level 4+ (EAL4+), ICSA, ITSEC E3, Checkmark, etc. The secure operating system was designed to meet TCSEC/NCSC criteria at the 'Orange-book' B2 level.
