Скачать или смотреть Episode 98 — Firewall Types: NGFW vs cloud-native firewall vs WAF

Firewall selection is a common CloudNetX decision point because different firewall types operate at different layers and solve different problems, and scenarios test whether you can match the control to the traffic. This episode defines an NGFW as a firewall with application-aware inspection and richer policy controls, a cloud-native firewall as an integrated provider control that aligns with cloud routing and identity constructs, and a WAF as an application-layer firewall designed to protect web applications by understanding HTTP patterns and common web threats. The first paragraph focuses on the selection logic: choose controls based on traffic type and where enforcement should occur, such as placing WAF protections at web ingress, using NGFW for broader segmentation and inspection across many protocols, and using cloud-native options where integration and scalability are primary requirements. It also explains that these controls can complement each other, but overlapping them without governance can create complexity and inconsistent outcomes.
