Firewall as a Service (FWaaS): A cloud-based solution that delivers firewall and other network security capabilities as a cloud service. It enables organizations to simplify their network security management by moving their security perimeter to the cloud, which can offer more flexibility, scalability, and cost-effectiveness compared to traditional on-premises firewall hardware. FWaaS typically includes features like intrusion prevention, URL filtering, and malware protection, and it is designed to protect both on-site and remote users in an increasingly decentralized IT landscape.
