Zscaler vs Cisco Secure Access -- SASE & Zero Trust Compared
Zscaler vs Cisco Secure Access
Cisco Secure Access brings together Cisco's extensive security portfolio (Umbrella, Duo, Talos, ThousandEyes) into a converged SASE platform, making it compelling for existing Cisco shops. Zscaler offers a more mature, cloud-native SASE architecture with superior inline inspection performance and a simpler operational model. Cisco wins on breadth of security portfolio and installed base; Zscaler wins on cloud-native architecture, inspection depth, and SASE maturity.
