Case Study: Open-Xchange strengthens attack surface monitoring and vendor risk management with UpGuard

Open-Xchange uses UpGuard for attack surface monitoring and to strengthen its vendor risk management processes

Open-Xchange, an international software and cloud provider, needed better visibility into its expanding attack surface and a more efficient way to manage vendor risk. Its security team relied on an internal vulnerability scanner and manual spreadsheet-based questionnaires, but both approaches were limited: scans were not real-time, asset discovery was incomplete, and vendor assessments were slow and difficult to complete.

With UpGuard, Open-Xchange automated external asset discovery, monitored third-party vulnerabilities, and moved vendor questionnaires into a more streamlined workflow. UpGuard also improved executive reporting with external validation and competitor comparisons, while helping the team cut manual work in vendor risk management and due diligence across 50+ vendors, 70+ risk vectors, and 2,500+ digital assets.
