Cisco Systems | Professional Services | 90400 | $53.8B | United States | Duo Security | Duo Multi-Factor Authentication | Identity and Access Management (IAM) | 2022 | n/a |
In 2022, Cisco Systems implemented Duo Multi-Factor Authentication as part of a zero trust initiative to secure application access for more than 100,000 users and 170,000 devices. The deployment used Duo Beyond and is categorized under Identity and Access Management (IAM).
Cisco configured Duo Multi-Factor Authentication to provide policy based access controls and device posture verification, emphasizing device health checks and multifactor prompts for application access. Configuration work focused on adaptive access policies and continuous device assessment, aligning authentication workflows with corporate identity and endpoint hygiene requirements.
The rollout was executed as a global IT and security deployment and completed in about five months, extending protection across corporate applications and remote access infrastructure. Operational telemetry captured approximately 5.76 million device health checks per month, and the implementation reduced reliance on traditional VPN usage while maintaining centralized authentication enforcement.
Governance for the Identity and Access Management (IAM) deployment was managed by Cisco’s IT and security organization, with phased policy enforcement and a support model sized to keep help desk contacts under 1 percent of users. The implementation consolidated MFA controls and device visibility under Duo Beyond, enabling centralized policy orchestration and ongoing operational monitoring.

CSC global | Professional Services | 7500 | $1.8B | United States | Duo Security | Duo Multi-Factor Authentication | Identity and Access Management (IAM) | 2014 | n/a |
In 2014, CSC Global deployed Duo Multi-Factor Authentication to secure employee VPN and Outlook Web Access accounts as part of its Identity and Access Management (IAM) program. The rollout spanned multiple countries and dozens of offices, covering a workforce of approximately 7,500 employees.
The implementation concentrated on MFA for remote access channels, specifically integrating Duo Multi-Factor Authentication into VPN access workflows and Outlook Web Access authentication. CSC Global replaced an RSA SecurID token program, centralizing authentication policies and enrollment workflows to reduce dependence on physical tokens.
Integrations were explicitly with the organization’s VPN infrastructure and OWA authentication stack, aligning MFA prompts with network access and mailbox access flows. Operational coverage included IT and security teams executing the rollout across the noted countries and office sites, with both remote workers and on-site employees in scope.
Governance and process changes removed token lifecycle management from day to day operations and improved user adoption and scalability for remote access MFA, outcomes described in the case study. The deployment positioned Duo Multi-Factor Authentication as the centralized Identity and Access Management (IAM) control for critical remote access points.

Day & Zimmermann | Construction and Real Estate | 43000 | $2.6B | United States | Duo Security | Duo Multi-Factor Authentication | Identity and Access Management (IAM) | 2014 | n/a |
In 2014, Day & Zimmermann deployed Duo Multi-Factor Authentication to meet DoD/CUI two factor requirements. The Identity and Access Management (IAM) initiative was executed by the companys IT and security organization in the United States, with an initial focus on securing VPN access for remote workers and contractors.
Duo Multi-Factor Authentication was configured to provide MFA for VPN and to extend endpoint and login protection across additional applications, and offline authentication capabilities were provisioned for traveling employees. Implemented functional capabilities included MFA challenge flows for VPN logons, device based authentication for endpoints, and offline passcode generation for users without network access.
The rollout followed a phased expansion from VPN to broader application coverage, aligning technical controls with DoD/CUI compliance requirements and centralizing administrative controls within IT/security. The deployment improved compliance and user experience while enabling offline MFA usage for traveling staff, and operational governance emphasized IT configuration management and access policy enforcement.
