Firewalls have come a long way from their humble beginnings of assessing network traffic based on appearance alone. Here are six predictions for the future of the firewall. For example, 5G is now used in more situations, such as in factories and for drone operations. And NGFWs aren’t done evolving.

Vulnerabilities at the operating system level may be exploited by rogue container workloads if not hardened. A typical example would be a policy to restrict container workloads from running in privileged mode. It is important to remember that just because an endpoint is behind a firewall doesn’t mean it is not a vulnerability.
