Traditional firewalls track the domains that traffic is coming from and the ports it’s going to. Nextgen firewalls go beyond that — they also monitor the content of the messages for malware and data exfiltration and can react in real time to stop threats. The newest iterations do even more, adding behavioral analytics, application security, zero-day malware detection, support for cloud and hybrid environments, and even endpoint protection.
