Check Point Technologies released the stateful inspection firewall back in the 1990s. Now it's bringing the world's first Web 3.0 firewall, furthering its mission of securing the digital world for everyone, everywhere.

Firewall technology harks back to age-old methods of physical defense when people first begun building walls to stop intruders. Yes, the Great Wall of China is a predecessor of today's firewall with attackers having moved online instead of in person.

Check Point has been at the forefront of firewalls since its founding over 30 years ago. In fact, Check Point created the stateful firewall. You can read the patent by Gil Shwed here. Previously, firewalls inspected data packets and looked up a table of rules to consider the source, destination, ports, and protocols before making an allow or reject decision. It was a good start but lacked any memory of previous packets, treating every new packet in isolation. Acceptance or rejection was based solely on the set of rules without context of the packet's place in a communication sequence. Check Point considered not all packets are independent, and by maintaining context-awareness, stateful firewalls could make more informed decisions and assess the packet as well as its relationship to previous packets. It was a huge paradigm shift and beat the competiting option of proxies on performance, protocol support, and security.

The world has continue evolving and we've now moved from stateful inspection to next-gen firewalls and to today's AI/ML-powered firewalls. An example is Check Point's own Infinity Platform, the culmination of decades of innovation and acquired technologies that combine to provide collaborative security solutions across an entire enterprise.

Not one to rest on its laurels, Check Point is still innovating and inventing and is building the world's first Web 3.0 firewall - helping protect and defend blockchain transactions be they financial or otherwise.

Check Point Technologies chief technologist Web 3.0 and head of product vulnerability research Oded Vanunu spoke with iTWire to explain what this means.
