Description: Firewall as a Service (FWaaS) is a cloud-based security solution that protects networks and applications from various cyber threats. Unlike traditional firewalls, which require on-premises hardware and maintenance, FWaaS offers a more flexible and scalable implementation, allowing organizations to manage their security centrally through the cloud. This technology easily integrates with other cloud services and provides continuous protection against attacks by filtering malicious traffic and ensuring that only authorized connections can access critical resources. Additionally, FWaaS aligns with the Zero Trust approach, where it is assumed that no connection is secure by default, and authentication and authorization are required for each access. This is especially relevant in cloud computing environments, where infrastructures are dynamic and users may be geographically distributed. In summary, FWaaS not only enhances security but also optimizes resource management and reduces operational costs by eliminating the need for physical hardware and its associated maintenance.
