Case Study: Sophos achieves secure, scalable BYOD for 3,000+ employees and reduced VPN reliance with Duo Security's Duo Beyond

Sophos - Customer Case Study

Sophos, a global leader in endpoint and network security, needed to enable secure worldwide mobility and a broader BYOD program while protecting a complex mix of SaaS and on‑premises applications. Their existing access stack—VPNs, ADFS, endpoint certificates and RSA tokens—was costly and cumbersome, limiting BYOD to fewer than 200 employees and preventing the agile, secure access the business required.

By deploying Duo Beyond integrated with Sophos Mobile, Sophos implemented a zero‑trust approach that verifies user identity and device trust (via Duo Device Insight and Sophos Mobile management) before granting application access. The result: mobile access scaled to 3,000+ employees and 7,000+ devices, self‑enrollment eliminated help‑desk setup, RSA infrastructure was phased out, and VPN use for app access became rare—delivering stronger, lower‑friction security and lower costs.
