Case Study: Sierra-Cedar achieves fast, seamless Juniper VPN protection from phishing with Duo Security

Sierra-Cedar - Customer Case Study

Sierra‑Cedar is a global technology and management consulting firm of about 1,000 largely remote employees that faced growing risk from phishing and spear‑phishing aimed at remote access to its Juniper VPN. After pen‑testing and social engineering exercises revealed credential theft as a primary attack vector, the company pursued stronger email filtering and an out‑of‑band two‑factor authentication solution to protect VPN logins.

They chose Duo for its seamless Juniper integration and fast deployment — setup took only a few hours using clear instructions — and its flexible authentication options (push, SMS, phone, tokens). Adoption was smooth with minimal support tickets, easy onboarding during acquisitions, and a measurable reduction in exposure to stolen credentials, prompting a strong endorsement from the company’s security leadership.
