Sendbird, an award-winning communication platform used by popular mobile apps, launched a managed bug bounty engagement with Bugcrowd two years ago. The program has rewarded over $53,000 to ethical hackers and found over 500 vulnerabilities, including RBAC issues, web vulnerabilities like XSS and CSRF, and potential user confidentiality compromises. Sendbird's public bug bounty program plays a crucial role in safeguarding their systems, and the company values the hacker community, aiming to establish lasting relationships with them. The collaboration with Bugcrowd has reduced operational burden, allowing Sendbird's security team to focus on enhancements. Sendbird prioritizes the hacker experience, issuing payouts within five days for valid reports, which has led to a steady stream of submissions.
