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.
Why Do Companies Need FWaaS?
FWaaS allows enterprises to partially or fully migrate network security to the cloud. With cloud-based firewall security, a third-party provider manages the solution. The provider maintains hardware infrastructure that supports the solution. The customer organization agrees to a service contract which outlines what features it can access depending on its subscription level.
In a local setup, the organization must procure an NGFW appliance, which incurs significant upfront costs. Because there is a need to keep up with new attacks and technological developments, there is a continuous need to upgrade and extend the NGFW. Each new purchase or upgrade requires staff to be trained in the new capabilities.
FWaaS is a cloud-based service that does not require an upfront investment and is continuously updated with the latest threat intelligence and security capabilities. Providers invest in advanced technologies and methods to improve network security, taking responsibility for keeping devices up to date.
