Case Study: CommSec achieves 100% client retention and stronger Zero Trust security with Duo Security

A Dublin-based managed service provider uses Duo to protect workers and data through a zero trust security approach

CommSec is a managed security provider founded in 2013 that focuses exclusively on enterprise-grade security for organizations of all sizes. After more than 50% growth in 2021 — driven by rising ransomware and high-profile incidents like the Irish HSE attack — many customers sought help knowing where to begin. CommSec typically starts with a security audit to identify gaps, then prioritizes fixes such as multi-factor authentication and device hygiene.

CommSec has partnered with Duo since 2017 to deliver a practical zero trust stack that is quick to deploy, integrates via API, and is device‑agnostic for diverse customer environments. Duo’s unified management and strong support make onboarding simple for MSPs and end users, enabling faster deployments and better endpoint control; as a result CommSec reported a 100% client retention rate in 2022 and stronger overall security postures for its customers.
