DarkLight is a cybersecurity company that develops Cyio, a platform designed to support Continuous Threat Exposure Management (CTEM) programs. The platform is built around the concept of continuously ingesting, correlating, and applying data from multiple sources — including vulnerability scanners, threat intelligence feeds, and asset inventories — to prioritize cyber risks in the context of an organization's business operations. Cyio integrates with vulnerability assessment platforms such as Tenable, Rapid7, and Qualys to continuously collect scan results and update risk statuses. It applies threat intelligence to an organization's specific environment rather than simply supplying raw intelligence data, allowing risks to be reprioritized on at least a daily basis. The platform supports multiple risk response paths, including acceptance, transfer, and mitigation, and includes audit trail capabilities to capture the rationale behind deviations such as accepted risks or false positives. A key feature of Cyio is its use of NIST-based "Information Systems" constructs, which allow organizations to represent business capabilities as collections of assets grouped by the types of information they process. This enables risk management to be contextualized by business function, not just by individual devices or software. Cyio integrates with ticketing and collaboration tools including Jira, ServiceNow, ConnectWise, Microsoft Teams, and Slack, enabling teams to assign and track remediation tasks directly from the platform. It also provides customizable dashboards and reporting tailored to different audience types within an organization.
