Case Study: WTW achieves an 80% reduction in remediation time (MTTR) with Mend SCA

WTW uses Mend to reduce MTTR

WTW (formerly Willis Towers Watson) is a global insurance advisor and consulting firm serving 140 countries. As their products shifted from installable applications to SaaS and API-driven delivery, WTW faced growing open-source licensing and supply-chain security risks — made urgent by high-profile dependency confusion incidents — and needed an SCA solution that integrated with CI/CD, scaled across business units, provided intuitive reporting, and delivered high-quality, low‑noise results.

WTW selected Mend SCA, centralized templating and assigned clear ownership to drive adoption and standardize developer workflows. The solution improved license compliance and developer visibility, freed resources for higher‑value work, increased contributing developers by 15%, and cut remediation time (MTTR) by at least 80%, enabling faster, more confident remediation across the organization.
