Common FortiSASE use cases

With FortiSASE, remote users (agent-based, agentless, and site-based) form secure connections to the Internet, data center, and cloud by accessing global FortiSASE security points of presence, which enforce an organization’s security policies regardless of remote users' locations. Following are examples of common FortiSASE use cases:

FortiSASE component	Use case	Description
Secure Internet access (SIA)	Agent-based remote user Internet access	Secure access to the Internet using FortiClient agent
	Agentless remote user Internet access	Secure access to the Internet using FortiSASE secure web gateway
	Site-based remote user Internet access	Secure access to the Internet using Thin Edge FortiExtender device as FortiSASE LAN extension
Secure private access (SPA)	Zero trust network access (ZTNA) private access	Access to private company-hosted TCP-based applications behind the FortiGate ZTNA application gateway for various ZTNA use cases. This access method allows for a direct (shortest) path to private resources.
	SD-WAN private access	Access to private company-hosted applications behind the FortiGate SD-WAN hub-and-spoke network. This access method extends private access for TCP- and UDP-based applications and offers data center redundancy.
	Next generation firewall (NGFW) private access	Access to private company-hosted applications behind the FortiGate NGFW. This use case extends private access for UDP-based applications and agentless remote users.
Secure SaaS access	FortiCASB SaaS access	Access to SaaS applications using FortiCASB Cloud/API
	FortiSASE Inline-CASB	Access control to SaaS applications using FortiSASE inline-CASB and SSL deep inspection on endpoint
SIA and SPA	Site-based remote users using FortiGate SD-WAN as a secure edge	Secure access to the Internet using FortiGate as FortiSASE LAN extension

Following is an example architecture of FortiSASE that incorporates all mentioned use cases:
