Rapid7

Rapid7 occupies the vulnerability management and penetration testing niche with its InsightVM, InsightIDR, and Metasploit (the world's most widely used open-source penetration testing framework) products, serving 11,000+ customers and $780M in annual recurring revenue. Its Command Platform unifies vulnerability exposure, threat detection, and incident response into a single console — a key requirement for resource-constrained security teams. Metasploit's 60M+ annual downloads have made it the reference standard in offensive security and the training tool of choice for ethical hackers and red teams globally, outperforming Tenable's Nessus in download volume by 20%. The company's managed detection and response (MDR) service acts as an outsourced SOC for mid-market enterprises that cannot hire full security analyst teams.
