What Is Firewall-as-a-Service (FWaaS)?

Firewall-as-a-Service (FWaaS) is a network security solution that provides a cloud-based firewall to monitor and control inbound and outbound network traffic.

FWaaS is typically delivered on-demand over the internet by a Managed Service Provider (MSP) as part of Infrastructure as a Service (IaaS) or Platform as a Service (PaaS) solutions. Organizations without the necessary expertise or resources can benefit from outsourcing these services, as the provider manages all administrative tasks, including firewall deployment, installation, troubleshooting, and patching.

Users don't have to deploy physical hardware to receive all the advantages of cloud resources, such as scalability and high levels of service availability.
