Cloud-native firewall services provide network security filtering without managing virtual appliances. AWS Network Firewall, Azure Firewall, GCP Cloud NGFW (powered by Palo Alto), and OCI Network Firewall each offer different rule paradigms, inspection capabilities, and pricing models. Some provide stateful L3/L4 filtering, others include L7 application-aware inspection, IDPS, TLS decryption, and URL filtering. This comparison helps you evaluate cloud-native firewall capabilities across providers, understand feature gaps, and plan multi-cloud network security architectures.
