HackerOne, a new volunteer-driven security firm run founded by former Facebook  security expert Alex Rice, took in $9 million in series A funding. Rice was previously Facebook’s (S FB) director of its security and Internet Bug Bounty program.

The company’s SaaS platform, custom built on Ruby, functions as a way for tech companies to participate in a bug-disclosure program that is completely confidential, said Rice.

According to Rice, he and the company’s other founders witnessed how large tech companies like Google (S GOOG) and Microsoft (S MSFT) were able to successfully use bug disclosure programs that aided in discovering vulnerabilities and fixing any potential problem with their platform. For smaller companies without the resources to create similar platforms within their own organizations, Rice saw the opportunity to bring a universal platform in which companies could share and discover bugs without the threat of potential litigation looming over one’s head.
