Firewall as a Service
Firewall as a Service (FWaaS) is a cloud-based firewall solution that provides network security services to businesses without the need for physical hardware. Instead of deploying and managing on-premises firewall appliances, users can leverage FWaaS to secure their network traffic and applications in the cloud.
