Case Study: a leading IT security company identifies exposed vendors and mitigates Microsoft Exchange zero-day risk with Exiger

Inherited Vendor Cyber Risk – Microsoft Exchange Server Zero Day Vulnerability

Exiger worked with a leading IT security company that was dealing with the late-September 2022 Microsoft Exchange Server zero-day vulnerabilities affecting Exchange Server 2013, 2016, and 2019. The customer needed better visibility into inherited vendor cyber risk and limited exposure across its ecosystem as attackers rapidly targeted the newly discovered flaws.

Using Exiger’s Supply Chain Explorer Cyber module and DDIQ Cyber Analysis, the company identified vendors potentially exposed to the vulnerability and created a real-time view of threat criticality for risk-based mitigation. Exiger’s data immediately flagged several at-risk vendors and revealed a direct nexus of Microsoft Exchange Server exposure within the customer’s ecosystem, enabling the team to focus response efforts where they mattered most.
