Firewall-as-a-Service (FWaaS) is a cloud service for security-related tasks. Such a centralized firewall
has the advantage that the company does not have to set up its own firewall at each company location. A central firewall provided by a cloud service provider controls all data traffic between the company headquarters and the branch offices. With the FWaaS service, all communication connections between the company headquarters, the branch offices and production sites, and also the data traffic of mobile employees, can be filtered, controlled and monitored for malware. The central firewall provides a uniform security concept in which the entire IT landscape of the company is integrated and which requires a uniform procedure for securing resources and data traffic. All employees are equally involved. .
