The turn of the century saw a new approach to firewall implementation with increased Internet speeds and firewall adoption within enterprises, overall performance was now behind the driving force of firewall purchases. Adopting the Netscreen firewall appliance was a preferred choice for many because of its faster inspection rate, which demanded less latency and high throughput at a lower cost.
With performance now high on the list of requirements, Netscreen had a significant advantage over its competitors due to its ease of use despite it did not offering a central management platform during its early stages. Performance and management had become the focal selling points during the mids and all firewall vendors thrived as security moved to the mainstream. A string of high-profiled attacks revolutionized the way security was perceived.
Security was no longer seen as a separate entity and instead, incorporated within the business model.
Firewalls acted as a first defence for organisations, limiting the risk to only the access defined. Because of their stand-alone functionality, a security engineer could deploy a firewall without the need for external hardware or operating system support to manage the entire system.
The firewall was at the forefront of security technology and became one of the most commercially successful security products on the market. However, as time progressed, so did the hardware and software performances between vendors and their firewalls, meaning the strategy now changed and a race had begun to see which vendors could push the boundaries beyond the traditional firewall.
Palo Alto Networks was able to position itself and its new technology, which could filter applications like Facebook at the perimeter of the network to control outbound user behaviour, as an essential security requirement to already existing systems. It would then spread its footprint before integrating its IPS with the next generation firewall which had become the industry standard.
This strategy allowed Palo Alto Networks to take a considerable amount of market share, leaving competitors to play catch up. The cat and mouse game between vendors escalated firewall development from a packet filter with limited functionality to a robust conglomerate of security functions that has become indispensable to the IT security industry.

The Evolution of the Firewall: From Data Center to the Cloud While a number of different types of firewalls exist, two of the most important steps in the evolution of the firewall are the introduction of the stateful firewall, invented by Check Point Founder and CEO Gil Schwed in , and the transition from the traditional data center firewall to the next-generation cloud firewall.
Stateless vs. Stateful Data center vs. Cloud Essential features Modern firewall. Stateful Firewalls One of the major milestones in the development of early firewalls was the transition from stateless to stateful firewalls. Data Center Firewall vs. Essential Features for the Modern Firewall The main difference between traditional firewalls and a next-generation firewall is that a modern firewall provides a range of features above and beyond simple port and protocol-based traffic inspection.
Unified Security Management Modern companies face a sophisticated and evolving cyber threat landscape and are protecting growing and diverse network environments. Integrated Threat Prevention The modern firewall should provide protection against both basic and advanced cyber threats. Hybrid Cloud Support Almost every enterprise is using a multi-cloud deployment, and the majority of these have hybrid cloud infrastructure.
Scalable Performance Traditional, hardware-based firewalls do not scale well, making it difficult and expensive for an enterprise to adapt to changing conditions.
Making the Move to a Modern Firewall Firewalls have undergone a number of stages in their evolution from the original, stateless firewall to the modern, cloud firewall. So defending the perimeter is nothing more than creating a barrier that separates the public part of the interconnection offered by the internet, and operated by large telecommunications companies and local providers as well, in the private network segments.
In computer networks, information travels through packets from one point to another. Each packet is a unit that carries a portion of identification header and data content , being routed independently through the internet.
DEC , marking, therefore, the first generation. This stage was marked as second generation of firewalls. In a short time, the third generation of firewalls appeared, when the commercialization of the DEC SEAL was started, counting on modern resources of application proxies. The combination of packet filtering and proxy in a single solution has made the hybrid firewall name begin to be more widely used in the market and academia.
In , Checkpoint launched Firewall-1 that was extremely important for the development and maturation of the security market, pioneering the GUI Graphic User Interface concept, as well as other technologies directly related to security. In the second half of the s, several parallel projects appeared, such as Squid and Snort that had as their main purpose not commercialization but the development and maturation of solutions and concepts over time.
These projects have, to this day, great use by commercial and free security solutions. At the same time, other companies emerged, and other security features were added to the solutions, making them increasingly hybrid. Features such as VPN , URL filters, QoS, integration or incorporation of antivirus, WAF and other solutions have allowed for greater robustness in the construction of secure environments for companies. The term is nothing more than a better name for the evolution of firewalls over the years.
