Company Overview
About Censys
Censys is a cybersecurity and internet intelligence company founded in 2017 and headquartered in Ann Arbor, Michigan, that provides a continuously updated, comprehensive global map of internet-facing infrastructure. The company's platform enables security teams, threat intelligence analysts, and government agencies to discover, monitor, and prioritize risks across all internet-exposed assets — including web servers, databases, cloud resources, IoT devices, and certificates — by scanning the entire public internet and building a real-time inventory of what is exposed.
Business Model & Competitive Advantage
Censys raised $70M in strategic funding, comprising a $40M Series D equity round led by Morgan Stanley Expansion Capital and $30M in debt financing, bringing total venture capital raised to more than $149M. The platform is trusted by more than 300,000 security practitioners worldwide and is used by organizations representing more than 50% of the Fortune 500. Censys's internet intelligence capabilities make it the authoritative data source for attack surface management (ASM) — the practice of discovering and continuously monitoring all internet-facing assets an organization owns or is exposed to — as well as for threat hunting and proactive incident response by identifying attacker infrastructure before attacks launch.
Competitive Landscape 2025–2026
Censys competes with platforms including Shodan (the original internet scanner), Palo Alto's Cortex Xpanse, and Tenable's attack surface management products — but distinguishes itself through the breadth, freshness, and accuracy of its internet scan data, which is updated continuously rather than periodically. The company's data is also used extensively by academic security researchers, vulnerability disclosure programs, and national cybersecurity agencies for internet-wide threat visibility. Censys is building AI-driven solutions for modern security operations to provide more intelligent, automated prioritization of exposure risks across the internet.
