Censys, the internet intelligence and insights platform, has raised $70m in a combined funding round to accelerate the development of its AI-driven security solutions.
The raise comprises a $40m Series D led by Morgan Stanley Expansion Capital, alongside $30m in debt financing. The round also saw participation from Decibel Partners, Greylock Partners, GV, Intel Capital, and a number of other undisclosed investors.
The company provides internet intelligence capabilities, helping enterprises, governments, and critical infrastructure providers track and respond to threats across their internet exposure. Its platform is used by more than 300,000 security practitioners worldwide, including organisations representing over 50% of the Fortune 500, and is positioned as a foundational source of first-party internet intelligence for security and threat intelligence teams globally.
Censys intends to use the fresh capital to accelerate the development of AI-driven solutions for modern security operations, building on its recently launched internet intelligence platform, as well as to drive faster innovation and pursue global expansion.
The funding arrives at a moment when internet infrastructure has become the primary attack vector targeting organisations, with remediation windows tightening as adversaries increasingly harness AI. Governments and businesses alike are seeking real-time intelligence to proactively block threats, manage supply chain risk, and protect critical infrastructure.
Censys founder and CEO Zakir Durumeric said, “AI is transforming every aspect of security operations, but its ultimate success will be fundamentally shaped by the quality and timeliness of the data available to it. Censys is positioned to drive this transformation with our leading intelligence to make AI actionable at global scale. This investment will enable faster innovation and global expansion.”
Morgan Stanley Expansion Capital managing director Pete D. Chung said, “Censys is widely recognized by their customers as THE authoritative source for Internet intelligence. We believe its unmatched visibility, combined with a clear strategy to build AI-driven solutions on top of its platform, positions Censys to be a foundational pillar of the modern security ecosystem.”
