Case Study: Ströer achieves centralized cybersecurity visibility and measurable risk reduction with BitSight

Bitsight Helps Leading German Media Company Get a Grasp on Cybersecurity Across its Vast Ecosystem

Ströer, a leading German media company with more than 100 subsidiaries and 15,000+ domains, needed a single, objective way to measure and report cybersecurity performance across its disparate business units. To address this, Ströer engaged Bitsight and adopted Bitsight Security Performance Management (SPM) to produce consistent security ratings and a trusted baseline for stakeholders.

Bitsight implemented SPM to assign numerical security ratings, group subsidiaries into monitorable clusters, track Key Risk Indicators, and generate condensed management reports. With Bitsight, Ströer can continuously monitor changes across its 100+ companies and 15,000+ domains, quantify risk with greater confidence, show progressive improvements in its security rating, and streamline audit-ready reporting for executives and investors.
