Zero Trust architecture ensures strict identity verification for every user and device attempting to access resources, minimizing risks of breaches by assuming no implicit trust. Secure Access Service Edge (SASE) integrates network security functions like SWG, CASB, FWaaS, and ZTNA with WAN capabilities to deliver secure cloud-native access. Explore the differences and benefits of Zero Trust and SASE to enhance your cybersecurity strategy.
Why it is important
Understanding the difference between Zero Trust and Secure Access Service Edge (SASE) is crucial for implementing effective cybersecurity strategies tailored to organizational needs. Zero Trust focuses on strict identity verification for every user and device, minimizing trust assumptions within the network. SASE combines Zero Trust principles with cloud-delivered security services, optimizing secure access for distributed workforces and resources. Recognizing these distinctions enables businesses to enhance security posture while supporting mobility and scalability demands.
