Tenable One Attack Surface Management
Tenable One Attack Surface Management identifies internet-facing assets and services that threat actors could reach externally. It continuously maps the internet, drawing on a map of more than 5 billion assets to help organizations find unknown assets. Continuous monitoring and change notifications track the external attack surface, and users can scan assets that have not yet been assessed to look for hidden risk. More than 200 metadata fields, filters, tags, and datatypes add context for assessing internet-connected assets. The product is part of Tenable One, which unifies external attack surface assets and exposure data. Connectors combine third-party security-tool information with Tenable sensor data; listed examples include CrowdStrike, Qualys, Rapid7 InsightVM, and ServiceNow CMDB. An Open Connector can ingest data from additional tools, internal systems, spreadsheets, or files. Listed use cases span cybersecurity, compliance, brand protection, mergers and acquisitions, competitive analysis, and legal. It is a hybrid deployment with Windows, macOS, and Linux support. Pricing starts at $4,790/yr, and there is no free plan.
