The white paper "Moving Beyond Users: The Case for Zero Trust SASE" by John Grady, commissioned by Zscaler, argues that traditional SD-WAN alone cannot achieve secure network transformation. While SD-WAN was intended to enable this transformation, it has limitations, particularly in security. Secure Access Service Edge (SASE) attempts to merge SD-WAN with security but often falls short. The paper emphasizes the need for a Zero Trust approach that extends beyond user access to all network connectivity, advocating for Zero Trust SASE as the solution. The paper concludes with Zscaler's Zero Trust SASE as a comprehensive approach to secure network transformation.
