A fully-featured packet-filtering router, Trustix Enterprise Firewall has advanced abilities including an intuitive graphical user interface (GUI) for visualizing and editing firewall policy.
This unique GUI enables you to manage traffic for all your zones (up to 24) as well as port forwarding, network address translation (NAT) and virtual private network (VPN) configurations.
Packet-filtering enables Enterprise Firewall to act as a router to accelerate data transmission. Meaning no more bottle necks due to time consuming proxies.
IP-address sharing by masquerading or NAT.
The underlying rules generated by the software are then fully optimized before being deployed- thereby optimizing the security and performance of your firewall's architecture, and avoiding errors and duplications.
Trustix Enterprise Firewall uses the IPsec protocol to encrypt data transmitted over the 'net- extending the security of your network to all arms of your business. Communications between your office and home users are protected using 168-bit 3DES encryption- triple the encryption, triple the security! Enables remote, secure configuration of multiple firewalls from one Windows or Linux desktop.
Trustix Enterprise Firewall Blockades and repel malicious attacks from hackers, Trojans, worms and infected files.
Based on Trustix Operating System, the most reliable and robust OS for Enterprise Server Applications, Trustix products will reduce the Total Cost of Ownership (TCO) to your company over their operational lifetime.
