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.
