The 2019 Duo Trusted Access Report: Expanding the Enterprise Perimeter with Zero-Trust Security for the Workforce

This year, more customers are using biometrics as an authentication factor to access applications with 77 percent of Duo customers having devices with biometrics enabled. Meanwhile, 71 percent of Duo customers have Flash uninstalled from their devices. And fewer Duo customers are falling for internal phishing simulations – 47 percent of phishing campaigns captured at least one set of credentials and 39 percent involved at least one out-of-date devices, which is an improvement over last year.

The Journey to Zero Trust

Duo has offerings to help you throughout your journey to a complete zero-trust security model. Our trusted access solution features everything you need to protect your applications and data at scale.

Confirm User Identities

Verify the identity of all users with effective, strong authentication (two-factor authentication) before granting access to corporate applications and resources.

Gain Visibility Into Access Activities

Gain visibility into every device used to access corporate applications, whether or not the device is corporate-managed, and without the use of onerous device management agents.

Ensure Trustworthiness of User Devices

Inspect all devices used to access corporate applications and resources in real time, at the time of access, to determine their security posture and trustworthiness.

Enforce Risk-Based & Adaptive Access Policies

Protect every application by defining policies that limit access to the users and devices that meet the organization’s risk tolerance levels.

Enable Secure Connections to All Applications

Grant users secure access to all protected applications (on-premises or cloud-based) through a uniform, frictionless interface accessible from anywhere.

That's all it takes to get
to zero trust.
