Case Study: Ströer achieves continuous external attack-surface visibility and secures hidden digital assets with CyCognito

Ströer Uncovers, Secures Hidden Digital Assets with CyCognito

Ströer, a leading German media company with more than 100 subsidiaries and a sprawling digital footprint, lacked a reliable inventory or map of its internet-facing assets and couldn’t calculate external risk. After a failed, costly consulting effort, the company selected the CyCognito platform for external attack surface discovery and continuous monitoring to address that gap.

CyCognito deployed its machine-learning and graph-based platform to autonomously discover and relate Ströer’s assets, quickly producing a single inventory and remediation workflow. The result: continuous visibility into roughly 40,000 assets, discovery and remediation of previously hidden vulnerabilities, elimination of shadow servers and unmanaged sites, independent monitoring for 50+ subsidiaries, faster remediation and reporting to the board, and reduced reliance on costly pen tests — all delivered by CyCognito within weeks.
