FWaaS (Firewall-as-a-Service) is a cloud-based security service that delivers firewall protection through the cloud rather than relying on traditional on-premises hardware firewalls. This service offers the same functionality as a traditional firewall, such as traffic filtering, intrusion prevention, and threat detection, but with the flexibility, scalability, and management simplicity that comes with being cloud-native.
