Cisco Zero Trust Overview

Why Cisco Zero Trust?

The most successful zero-trust solutions should seamlessly integrate with your infrastructure without entirely replacing existing investments. Cisco Zero Trust provides a comprehensive approach to securing all access across your applications and environment, from any user, device, and location.


Zero trust is a strategic approach to security that centers on the concept of eliminating trust from an organization's network architecture. Trust is neither binary nor permanent. We can no longer assume that internal entities are trustworthy, that they can be directly managed to reduce security risk, or that checking them one time is enough. The zero-trust model of security prompts you to question your assumptions of trust at every access attempt.

Cisco believes a zero trust security strategy is best executed by taking a connected, cohesive, and holistic approach.

A zero-trust approach:

  • Establishes trust in every access request, no matter where it comes from
  • Secures access across your applications and network
  • Extends trust to support a modern enterprise across the distributed network

How is a zero-trust approach different?

Traditional security approaches assume that anything inside the corporate network can be trusted. The reality is that this assumption no longer holds true, thanks to mobility, BYOD (bring your own device), IoT, cloud adoption, increased collaboration, and a focus on business resiliency. A zero-trust model considers all resources to be external and continuously verifies trust before granting only the required access.


The platform approach of Cisco Zero Trust provides a balance between security and usability. Security teams can make it harder for attackers to collect user credentials and network access and to move laterally, and users can get a consistent and more productive security experience--regardless of where they are located, what endpoints they are using, or whether their applications are on-premises or in the cloud. Its comprehensive approach to securing all access protects the workforce, workloads, and workplace.

We establish trust by verifying:

  • User and device identity
  • Device posture and vulnerabilities
  • Any workloads
  • Application and service trust
  • Any indicators of compromise

Zero-trust pillars

Cisco Duo, Cisco SD-Access, Cisco Secure Workload

Security is not one-size-fits-all. When approaching zero-trust design, it is easier to break it down into three pillars: workforce, workload, and workplace. These align with the model proposed by Forrester to simplify adoption. There are nuances to address in each area, while all work toward the same goal.

This pillar focuses on making sure users and devices can be trusted as they access systems, regardless of location. Cisco Zero Trust provides solutions that establish trust in users and devices through authentication and continuous monitoring of each access attempt, with custom security policies that protect every application. It allows you to:
