Firewall as a Service (FWaaS) is a new and revolutionary way of delivering firewall and other network security capabilities as a cloud service. Enterprises have always deployed next generation firewalls as appliances. While form factor varies between physical and virtual appliances, deployed on-premises or in the cloud, customers need to support the full appliance life cycle. Distributed locations need dedicated appliances that have to be sized and upgraded to accommodate business growth. Appliance software has to be patched and upgraded, and policy management must be done on an appliance basis.
FWaaS is a new type of a next-generation firewall. It doesn’t merely hide physical firewall appliances behind a “cloud duct tape”, but truly eliminates the appliance form factor, making network security (URL Filtering, IPS, AM, NG-AM, Analytics, MDR) available everywhere. In essence, the entire organization is connected to a single, logical global firewall with a unified application-aware security policy. Gartner has highlighted FWaaS as an emerging infrastructure protection technology with a high impact benefit rating.
