Twilio's Bug Bounty Program has been in operation since 2015, with the goal of tapping into the skills and talent of security researchers from around the world to help keep Twilio safe. The program has grown significantly over the years, with almost 1,300 researchers participating and a total bounty paid exceeding $300k. To date, the program has received over 450 submissions in 2019, with 50 being Priority 1 findings, and has seen a significant increase in the average reward for a finding from $400 to $1500. The program has also implemented measures to better protect researchers, such as the Safe Harbor Program, and will continue to improve its scope and researcher experience in 2020, including adding assets and features to Twilio SendGrid products.
