ITShield Networks Inc.(http://www.itshield.com) has released a
wonderful firewall - ITShield Firewall:
ITShield Firewall, a transparent firewall, contains the advantages of
all three critical firewall architectures - packet-filtering, Stateful
Inspection, and application gateway firewall. By using some advanced
technologies, ITShield Firewall can handle more than 5000 TCP
sessions, unlimited UDP sessions, and unlimited IP sessions at
application-level in parallel. Because application proxy provides the
highest level of security and flexibility, ITShield Firewall handles
all the sessions in application-level by default. Furthermore,
ITShield Firewall can drop the unwanted requests at packet level. If
the high-speed network traffic keeps the firewall very busy, the
administrator can enable Stateful Inspection.
ITShield Firewall supports PPTP VPN and IPSEC VPN. It is very easy for
you to configure them.
You can use ITShield Firewall for free before Jan 1, 2004.
