One might consider the firewall the most significant invention in cybersecurity in the last 30 years. The firewall has certainly evolved since its inception in 1988 as simple packet filters, launching with stateful filters, then upgrading to its third-generation application layer firewall and more recently upgrading again to the next-generation firewall (NGFW).

While NGFW is certainly part of the cybersecurity stack, NGFW is no longer revolutionizing the way we protect our critical business assets.

Today’s cybersecurity strategies have been disrupted by two new models: the Zero Trust model and DevSecOps.
