What Fortinet solution is required for FortiSASE point of presence (POP) to connect as a spoke?

In the context of FortiSASE and its architecture, the Next Generation Firewall (NGFW) is essential for ensuring secure connectivity between the FortiSASE point of presence (POP) and other network components, such as branch offices or remote users acting as spokes. The NGFW extends its security capabilities beyond traditional firewall functions, offering features such as deep packet inspection, application awareness, and intrusion prevention, which are critical in maintaining a secure and efficient network environment.

Furthermore, the NGFW can support various security policies that adapt to the dynamic nature of a cloud-based SASE model, providing an optimized connection for remote users and devices. Its ability to integrate seamlessly with other Fortinet products also enhances the overall security architecture by maintaining consistent policy enforcement and visibility across different locations.

While other options might seem relevant in different aspects of network management, they do not effectively provide the same level of integrated security and connectivity required for FortiSASE POP to function optimally as a spoke. For instance, a VPN concentrator primarily manages multiple VPN connections rather than enforcing security policies directly, and a dedicated firewall appliance may lack the advanced features that an NGFW provides in the context of SASE. A unified threat management system, while useful, generally encompasses various security functionalities
