This case study outlines the implementation and outcomes of BigCommerce's bug bounty program in collaboration with Bugcrowd. Initiated in October 2020, BigCommerce's private bug bounty program has attracted nearly 500 researchers, leading to the validation of over 75% of identified vulnerabilities within four days. The program transitioned to a public model, allowing global security researchers to report vulnerabilities, thereby enhancing the company's cybersecurity strategy. The case study details the challenges faced by BigCommerce in identifying security vulnerabilities across its IT platforms and applications. It also highlights the benefits of partnering with Bugcrowd, which manages the vetting and triaging of claims, allowing BigCommerce to focus on rapid remediation. The program complements traditional security measures, such as code reviews and penetration testing, by providing an additional layer of defense. The insights from this case study emphasize the importance of collaboration with external researchers to strengthen security practices and protect stakeholders.
