Summary

Censys Attack Surface Management continuously measures an organization’s internet-facing exposure from an outside-in perspective. It maps the global internet across all 65,000 ports and discovers exposed assets, including services on nonstandard ports, hosts with self-signed certificates, and hosts on residential networks. Continuous monitoring tracks changes such as new hosts, ports, certificates, and services, with alerts for meaningful changes. The product detects more than 700 exposure types and misconfigurations and over 7,000 vulnerabilities; organizations can enable or disable risk types and assign severity levels. Prioritization includes EPSS, KEV, and other vulnerability scoring mechanisms. Integrations with ticketing, vulnerability management, and security tools can help create and track remediation tasks. Listed integrations include AWS, Azure, Google Cloud, ServiceNow, Jira, Slack, Microsoft Sentinel, Tenable, Qualys, and Swimlane. Executive and audit-friendly views cover exposure trends and remediation progress. Pricing is quote-based on Assets Under Management, a count Censys says is lower than its Attack Surface Size metric.
