Continuous attack surface management pioneer Bishop Fox continues to attract the attention of investors with the banking of another $46 million in growth funding led by WestCap.
The Phoenix, Arizona company said the new cash infusion adds to a $75 million Series B round secured earlier this year to build and market an attack surface management platform that automates the discovery and mitigation of security weaknesses.
In addition to WestCap, NextEquity Partners and Rockpool Capital joined the latest funding.
Bishop Fox, an 18-year-old firm known for its penetration testing and offensive security expertise, has raised more than $154 million in lifetime funding, including a $25 million Series A investment from Forgepoint Capital.

The company said its flagship Cosmos platform is capable of performing continuous offensive testing at scale, executing more than 2.3 billion operations and identifying 13,000+ exposures per week, saving security teams more than 5,000 hours per year in vulnerability identification and triage.
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.
The technology is meant to address gaps in point-in-time penetration testing and vulnerability management and is a highly competitive category with multiple startups jostling for market share.
Well-funded players in the attack surface management space include RunZero, CyCognito, Censys and Cyberpion.
