Censys Banks $75M for Attack Surface Management Technology

Michigan startup raises $75 million in new funding as venture capital investors bet big on attack surface management technologies.

Michigan startup Censys has deposited $75 million in new funding as venture capital investors continue to bet big on technology to help organizations automate the finding and fixing of serious security problems.

Censys said the new financing included a $50 million Series C venture round and $25M in debt funding led by SVB Capital, Silicon Valley Bank.

The Series C was led by Decibel Partners, GV, Greylock and Intel Capital and included new investors Ascension Ventures and Four Rivers Partners.

Censys, based in Ann Arbor, competes with the likes of Randori, Bishop Fox, NCC Group, CyCognito and a wave of new startups hawking tools to help defenders with Internet-wide scans for exposed corporate assets.

The company claims it has built the most complete and accurate collection of global internet infrastructure data and provides technology to enrich the data with context to drive security decisions.

Since its last raise, a $35 million round led by Intel Capital, Censys said it recorded 130% annual recurring revenue (ARR) growth, a key metric used by subscription-based SaaS companies.

Censys counts prominent organizations like Google, NATO, the Swiss Armed Forces, and the U.S. Department of Homeland Security among its customer base.

The attack surface management category has grown in importance to solve problems with vulnerability and patch management, especially for software and other assets that are exposed to the internet.
