If it were on public display, this portion of our Firewall Blowout would be the geek equivalent of the Chicago Auto Show. Our Chicago Neohapsis partner labs focused on the muscle cars: enterprise-class, gigabit-capable network firewall appliances and turnkey systems that support high-availability stateful failover, VPNs and centralized management as well as DI (deep inspection), which we define as having the ability not only to perform stateful packet filtering, but also to inspect packet payloads higher up the OSI model using specific attack signatures and Layer 7 protocol engines.

Once they were border controls, then customs and excise, now they are the police, the fire brigade and the health service. Can the firewall become the sole security device in the enterprise? Zaphod Beeblebrox, the two-headed anti-hero of Douglas Adams’ Hitchhiker’s guide to the galaxy, wears the future of firewalls on his head. His Joo Janta 200 Super-Chromatic Peril Sensitive Sunglasses turn black at the first hint of danger. This saves him from witnessing frightening events, so he remains cool and un-panicked in a dangerous universe.

Guardian Digital, Inc., a leader in open source security products, today announced the release of a new firewall product that will revolutionize internet security as we know it, forever.

Guardian Digital CEO Dave Wreski explains, "Our new product works differently from most other firewalls on the market, which can possibly allow dangerous packets into protected networks. Our technical wizards realized that all virus, worm, and malware authors use dangerous 'zeroes' in their binary code, therefore our new firewall product blocks all 'zeroes' while allowing the friendly, useful 'ones' through."
