The provided texts collectively describe Secure Access Service Edge (SASE) as a modern, cloud-based network architecture integrating networking and security functions to provide secure and efficient access to applications and data for a distributed workforce. SASE aims to overcome the limitations of traditional network security by offering benefits like enhanced security, simplified management, improved performance, scalability, and cost savings. While SASE presents implementation challenges such as complexity, vendor lock-in risks, and the need for careful planning, it is increasingly essential for organizations adopting remote and hybrid work models and navigating evolving cybersecurity threats and compliance requirements. The sources also touch upon related concepts like Zero Trust Network Access (ZTNA) and Secure Service Edge (SSE), as well as the ongoing evolution and future trends of SASE.
