Tenable Attack Surface Management

Tenable Attack Surface Management delivers continuous, comprehensive visibility into an enterprise full external cyber exposure, mapping internet-facing digital assets and identifying risky technologies that expose organizations to cyber attacks. Operating from an outside-in perspective, the platform discovers every domain, subdomain, IP address, cloud instance, and web server connected to an organization brand, helping security teams eliminate perimeter blind spots that traditional internal vulnerability scanners cannot detect.

The solution utilizes automated internet-wide discovery engines that analyze DNS records, WHOIS data, public certificate transparency logs, and IP routing tables to uncover forgotten marketing domains, subsidiary infrastructure, and shadow cloud resources. Key technical features include automated risk scoring for external assets, continuous change detection that alerts on newly opened ports or expired TLS certificates, rogue asset identification, and automated asset categorization. By seamlessly feeding external discovery data into Tenable risk-based vulnerability management workflows, the solution allows organizations to evaluate external asset exploitability and prioritize remediation efforts effectively.

Tenable Attack Surface Management integrates with Tenable One Exposure Management Platform, Tenable Vulnerability Management, ServiceNow, Splunk, and enterprise ITSM systems. Core enterprise use cases include identifying unknown shadow IT infrastructure, discovering exposed administrative interfaces on the public internet, monitoring third-party cloud assets, and satisfying regulatory requirements for continuous attack surface inventory. Tenable Attack Surface Management delivers exhaustive external asset discovery, continuous monitoring, and actionable cyber exposure insights.
