Zero Trust Starts with Secure Access

Never trust; always verify. A zero trust model establishes trust in users and devices through authentication and continuous monitoring of each access attempt, with custom security policies that protect every application.

How to Implement Zero Trust

In order to implement a zero trust architecture, organizations must meet four functional requirements: establish trust, enforce trust-based access, continuously verify trust, and respond to changes in trust. Duo’s user-focused approach provides each of these functions in a way that frustrates attackers and not users, so you can move towards zero trust with zero friction.

  • Duo authenticates users and verifies devices to establish trust
  • Duo enables access and applies powerful and granular adaptive policies to enforce trust-based access
  • Duo provides risk-based authentication to continuously verify trust
  • Duo provides alerts, logs, and anomalous login detection to allow organizations to detect and respond to changes in trust

Why Duo for Zero Trust

Provides Strong Security

Duo provides a critical foundation for zero trust strategy. It ensures that only the right users with the right devices are accessing the right applications, aligning with the zero trust concept of “least privilege.”

Continuous trust assessment with risk-based authentication adjusts security requirements in response to risk signals in real-time to help ensure secure access.

Enables High Productivity

Duo enables zero trust security that doesn’t get in the way of users. With its simple and intuitive interface and capabilities, Duo provides a frictionless authentication experience. 

The user-friendly administrator dashboard helps IT and security teams gain deep visibility into all devices attempting to access resources, enabling efficient zero trust security policy creation and fast incident response.

Delivers Unmatched Value

Duo simplifies zero trust implementation with an all-in-one solution that includes strong MFA, passwordless, single sign-on, VPN-less remote access, trusted endpoint verification, and more, that works with any organization’s environment. 

Duo is lightning fast to deploy and can significantly reduce IT helpdesk overhead and costs thanks to user self-service features such as enrollment, password resets, password management, and endpoint remediation.

The Value of Zero Trust at Cisco

The number $3.4M representing the annual savings in employee productivity saved by Cisco implementing zero trust.

$3.4M annual savings in employee productivity

As a result of 410,000 fewer VPN authentications per year.

The $500K number represents the annual savings in IT helpdesk support costs when Cisco implemented zero trust.

$500K annual savings in IT helpdesk support costs

With <1% of users contacting the IT helpdesk vs. 7% for typical security technology rollouts.

The 86K number represents the potential compromises averted per month when Cisco implemented zero trust.

Five Phases to Implement Zero Trust

We have developed a plan with five iterative phases for how you can implement zero trust for user and device access to applications. Learn how Duo can help your business with all five phases to accomplish a zero trust architecture.

Phase 1: Establish User Trust

Leverage phishing-resistant MFA to verify users truly are who they say they are. Make it easy for users to strongly authenticate – on managed and unmanaged devices, and whether they’re employees or contractors (e.g., BYOD).

The number 2 representing the second phase of our five phased approach to zero trust.

Phase 2: Verify Device Trust

Apply device posture checks and block unwanted access with a trusted endpoint policy. Guide users in fixing device trust issues on their own before gaining access to apps, and without having to call the helpdesk.

The number 3 representing the third phase of our five phased approach to zero trust.

Phase 3: Enable Access to Applications

Shrink the attack surface by reducing password usage with passwordless SSO and make it faster and more convenient for users to get to the apps they need with VPN-less access (e.g., ZTNA) – whether SaaS-based or private.


The number 4 representing the fourth phase of our five phased approach to zero trust.

Phase 4: Enforce Contextual Access

Deploy risk-based authentication, increase device visibility, and adapt access dynamically based on user or device behavior. Step up access based on increased risk and ease up access requirements based on lowered risk. Respect the user’s privacy and productivity by anonymizing location data and eliminating unnecessary decisions.

The number 5 representing the fifth phase of our five phased approach to zero trust.

Phase 5: Verify Trust Continuously

Continuous trusted access relies on innovations like Wi-Fi profile analysis and session trust analysis. By leveraging open protocols to communicate signals and react to changes in risk, session trust analysis brings visibility and control to a traditionally opaque surface: risk remediation during the established session.

Frequently Asked Questions

What is zero trust?

Zero trust is a strategy for securing your business by eliminating excessive trust and continually verifying trust – of a user, device, application, or network – before access is granted. By never assuming trust, always verifying it, and applying least privilege to each access control decision, organizations can reduce risk systematically.

What are the principles of a zero trust architecture?

The principles of zero trust architecture are: never assume trust; always verify it; and enforce the principle of least privilege. Using guidance such as the CISA Maturity Model can help organizations make progress. It outlines five pillars to apply zero trust policies: identities (users), devices, networks, apps, and data; with three cross-cutting capabilities: visibility & analytics, automation & orchestration, and governance.

What are the functional requirements of a zero trust platform?

  1. Establish trust for users, devices, and applications driven by visibility and context
  2. Enforce trust-based access based on the principle of least privilege
  3. Continuously verify trust to detect any change in risk even after initial access is granted
  4. Respond to change in trust by investigating and orchestrating responses to potential incidents

Where are zero trust policies enforced?

Zero trust policies are enforced across networks, users, devices, applications, and clouds.

What are some examples of zero trust in action?

These are some examples of zero trust in action:
• Securing hybrid work
• Applying micro-segmentation to workloads at scale
• Unifying access policy across environments
• Orchestrating unified security workflows for faster incident response
