KeyCaliber provides a vulnerability and patch management platform that helps organizations gain visibility into their security fundamentals. The company was founded by a former Executive Office of the President and Department of Homeland Security security leader who identified a pattern where security spending increased without corresponding improvements in security outcomes. The platform uses patent-pending machine learning technology to compute risk for each asset and prioritize vulnerabilities based on business impact. KeyCaliber aggregates data from existing security tools to provide security stack analysis, coverage intelligence, and business impact intelligence. The platform enables organizations to identify critical assets, detect gaps in security controls, and understand which assets pose the greatest risk to business operations. KeyCaliber's approach focuses on strengthening security program fundamentals rather than adding more security products. The platform provides visualizations and metrics for senior leadership while offering detailed technical data for vulnerability and patch management teams. Organizations can track patching cadence, open vulnerabilities, system hardening, scan coverage, and risk by business unit or asset group. The company serves security teams that need to prioritize remediation efforts based on asset criticality and business impact. KeyCaliber correlates vulnerability data with factors such as cost of data breach, operational impact, and internet exposure to help organizations make informed decisions about patch deployment and risk mitigation.
