$974.60M revenue TTM 2025 (+11% YoY); $3.51B market cap NYSE:TENB; #1 worldwide vulnerability management IDC 2024; Vulcan Cyber acquisition $148M Feb 2025; vulnerability leader
Tenable is a cybersecurity company founded in 2002 and headquartered in Columbia, Maryland, that pioneered the vulnerability management category and remains its global leader. The company was founded by Ron Gula and Jack Huffard around the Nessus vulnerability scanner, one of the most widely deployed security tools in the world, with a mission to help organizations understand and reduce their cyber exposure across their entire attack surface. Tenable's core conviction is that organizations cannot defend what they cannot see — and that comprehensive, continuous visibility into vulnerabilities is the prerequisite to effective security.\n\nTenable's platform portfolio includes Tenable.io (cloud-native vulnerability management), Tenable.sc (on-premises), Tenable OT Security (operational technology), Tenable Web App Scanning, Lumin (exposure-based risk scoring), and the Tenable One exposure management platform. The company serves enterprise and government customers globally with a product suite that covers cloud workloads, on-premises infrastructure, operational technology, and web applications. In February 2025, Tenable completed the $148 million acquisition of Vulcan Cyber, a risk-based vulnerability prioritization platform, expanding its capabilities in correlating vulnerability data with threat intelligence and business context.\n\nTenable reported trailing twelve-month revenue of $974.60 million as of 2025, up 11% year over year, and was named the number one worldwide vulnerability management vendor by IDC in 2024. The company trades on Nasdaq under the ticker TENB and competes against Qualys, Rapid7, and a growing set of cloud-native exposure management entrants. Its Nessus heritage, market leadership validation from IDC, and strategic expansion into broader exposure management through Tenable One and the Vulcan Cyber acquisition position it as the reference platform for enterprise vulnerability and exposure management.
Open-source observability leader with $6B valuation; Grafana dashboards plus Loki/Tempo/Mimir stack serving millions of installations as Datadog alternative with community-driven adoption.
Grafana Labs is the company behind Grafana — the world's most widely used open-source observability and data visualization platform — providing the Grafana Cloud managed service, Grafana Enterprise, and a suite of open-source tools including Loki (log aggregation), Tempo (distributed tracing), and Mimir (long-term Prometheus metrics storage). Founded in 2019 by Raj Dutt, Torkel Ödegaard, and Tom Wilkie (the creators of the original Grafana open-source project) in New York, Grafana Labs has raised over $600 million at a $6 billion valuation.\n\nGrafana's open-source project — downloadable and self-hostable for free — has driven extraordinary community adoption: millions of Grafana installations globally power engineering, IoT, and business dashboards at organizations from startups to large enterprises. Grafana's plugin ecosystem connects to 200+ data sources (Prometheus, InfluxDB, Elasticsearch, AWS CloudWatch, databases), making it the universal observability visualization layer. Grafana Cloud packages the open-source tools into a fully managed SaaS offering with unlimited metrics, logs, traces, and dashboards.\n\nIn 2025, Grafana Labs competes in the observability platform market against Datadog, New Relic, Dynatrace, and the ELK/OpenSearch stack for enterprise monitoring and observability. Grafana's open-source-first model creates a moat through developer community and ecosystem — engineers who build personal dashboards on Grafana become advocates for Grafana Cloud at their employers. The company's OpenTelemetry alignment and multi-source data philosophy ("query any data, anywhere") differentiates it from Datadog's monolithic agent model. The 2025 strategy focuses on growing Grafana Cloud enterprise adoption, advancing AI-powered Sift (automatic anomaly investigation), and expanding the Grafana IRM (incident response management) product.
