NetScreen's full-featured firewall uses technology based on stateful inspection, securing against intruders and denial-of-service attacks. NetScreen's custom-built ASIC processes the firewall access policies and encryption algorithms in hardware.

If the access policies of the Netscreen firewall are misconfigured, then the environment will be exposed to harmful virus attacks and intrusion from malicious users. It is therefore imperative that the firewall is monitored 24 x 7 for availability and all-round health. This is where eG Enterprise helps administrators.
