Secure Access Service Edge (SASE) is a cloud-based architectural model that unifies network connectivity and security functions into a single platform. It moves network controls from traditional corporate data centers to the cloud edge, allowing for simpler, secure, and consistent access to applications and data for users regardless of their location. This approach is particularly beneficial for supporting hybrid and remote work environments and modern cloud-based infrastructures. SASE integrates various security services, often based on Zero Trust principles, such as Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Firewall-as-a-Service (FWaaS), and Zero Trust Network Access (ZTNA), with Software-Defined Wide Area Networking (SD-WAN) capabilities. This consolidation simplifies IT infrastructure, enhances security, reduces complexity and costs, and improves overall performance.
