We build, install, and configure highly effective Linux Firewalls for a fraction of the cost of specialized hardware.

Adaptive Firewalls with VPN and Failover capability

We can build, install, and configure a highly effective Linux Firewall for a fraction of the cost of specialized hardware yet the Linux Firewall will be just as effective and reliable. Better still, your Linux and Unix system administrators already will know how to maintain it. Our custom designed Firewall rules block virtually all common attacks and scans. Our firewall has been benchmarked at triple the bandwidth of Cisco Pix Firewall and one quarter the cost to deploy. Both North American and European power can be accommodated.

Cracker Trap™ Adaptive Firewall

Supplement the basic Firewall with our Cracker Trap™ that operates as an Adaptive Firewall. It detects when a cracker is trying to break in and will lock him permanently out of your network in a fraction of a second, forever eliminating him as a problem. It then will notify you via email and/or pager of the action taken. It even can generate audio and visual alerts by playing any sound file on the speakers of the Firewall system or on another system via a secure connection and can flash the lights or other devices via an X10 interface.

When running Cracker Trap™ at multiple locations, a cracker attacking one location will be locked out of all your Cracker Trap™ firewalls at the same time.

It is very customizable and can be programmed with a list of trusted systems to avoid locking them out while still alerting you if they are acting suspiciously and might be compromised. It determines in an unspoofable way what system has tried to attack your network so that the site's system administrator can be notified to get the system shut down or for use in legal actions. It is compatible with almost all other IDS, Firewall, and anti-virus systems.


Load Balancing

For clients with multiple Internet feeds, we can automatically balance traffic between the two feeds for maximum performance.

 

 

Redundant Fault-tolerant Failover Capability

We offer a fault-tolerant failover capability so that if your primary Internet connection fails, all traffic will be re-routed through a secondary connection. Internet access from your desktop systems, VPN capability between your offices, and Internet access to your servers can be failed over automatically. The failover will be transparent to your VPN sessions. Typically, the primary connection would be T1 and the secondary connection would be DSL or dialup. Some clients have two separate T1 connections for redundancy.

An additional fault-tolerant failover capability is available so that if a Firewall component fails, a switch to a backup system will happen automatically almost immediately. Even existing sessions will be preserved when this happens.

The Firewall can be further supplemented with automatic 24x7 monitoring of your network.

 

Virtual Private Network

A Virtual Private Network (VPN) capability can be added to your organization's Linux Firewalls in its different offices as well as for telecommuters and travelers running Windows, Macs, Linux or Unix. This allows secure communication between your offices, enjoying the low cost of communicating over the Internet with the security of encrypted communication. Our VPN capability is invisible to your people and they do not need to do anything special to enjoy it nor can they defeat it.
