Tenable has built the market-leading vulnerability management and exposure management platform since its founding in 2002. Headquartered in Columbia, Maryland, Tenable is best known for Nessus, the world's most widely deployed vulnerability scanner used by millions of security professionals. The company went public in 2018 and continues expanding from vulnerability scanning to comprehensive cyber exposure management.
Tenable's platform includes Nessus vulnerability scanning, Tenable.io for cloud-delivered vulnerability management, Tenable.sc for on-premises deployments, Tenable.ad for Active Directory security, and web application scanning. Their Cyber Exposure approach goes beyond traditional vulnerability management to help organizations measure and communicate cyber risk in business terms. Tenable integrates with diverse IT environments including cloud platforms, containers, OT systems, and IoT devices. Their research team regularly discovers and reports critical vulnerabilities.
The company differentiates through comprehensive coverage across IT, cloud, OT, and IoT environments from a single platform. Tenable's Predictive Prioritization uses data science to focus remediation on vulnerabilities most likely to be exploited. Their exposure score provides business-friendly risk metrics that resonate with non-technical stakeholders. Strong community support and extensive integrations make Tenable easy to deploy and operate. However, effective use requires process maturity around vulnerability management.
For organizations requiring comprehensive vulnerability assessment and exposure management across diverse IT environments, Tenable delivers industry-standard capabilities. Their platform approach suits enterprises seeking to consolidate multiple scanning tools. Best fit for mature security programs requiring quantifiable risk metrics, organizations with heterogeneous IT environments spanning on-premises and cloud, and companies needing to demonstrate cyber risk reduction to boards and regulators.
