Censys Attack Surface Management
What Censys Attack Surface Management is
Censys Attack Surface Management helps security organizations identify and monitor internet-facing infrastructure from an outside-in perspective. It maps the global internet across all 65,000 ports and uses first-party scanning to find exposed assets, including services on nonstandard ports, hosts with self-signed certificates and hosts in residential networks. Continuous monitoring tracks changes such as newly visible hosts, ports, certificates and services, and can alert teams to meaningful changes. The product detects more than 700 exposures and misconfigurations and over 7,000 vulnerabilities. Teams can enable or disable risk types and assign severity levels. Prioritization includes EPSS, KEV and other vulnerability risk scoring mechanisms. Integrations with ticketing, vulnerability management and security tools can create, route and track remediation tasks. Listed integrations include AWS, Azure, Google Cloud, Microsoft Sentinel, ServiceNow, Slack, Jira, Tenable, Qualys and Swimlane. Executive and audit-friendly views cover exposure trends and remediation progress. Pricing is quote-based on Assets Under Management, which Censys says is a lower count than the Attack Surface Size metric.
