Bitsight Security Ratings vs Tenable One Attack Surface Management

Bitsight Security Ratings helps security and risk leaders assess, monitor, prioritize, and communicate an organization’s cyber risk. It rates organizations on a 300–820 scale and assigns letter grades for individual risk vectors. Bitsight says ratings update daily, while validated rescan results can appear within minutes. Risk data is grouped into Compromised Systems, Organizational Diligence, User Behaviors, and Public Disclosures. Its methodology combines external data mapped to organizations with AI and analyst intelligence to assess risk vectors associated with breaches. Dynamic Remediation provides rescan feedback and rating credit after validated fixes involving SSL configurations, SSL certificates, open TCP ports, server software, and web application security. Plans cover rating and issue management, benchmarking, APIs, integrations, subsidiary management, continuous monitoring, and vendor-risk workflows. Integrations are described for GRC, vendor-risk, SIEM, SOAR, and workflow automation, including ServiceNow and Jira. Developers can build around Security Rating through APIs and MCP access. The product serves security, GRC, third-party risk, board, investor, insurer, financial, and government users. Pricing is on request.

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.
