This post explains how Sophos' Responsible Disclosure Program works with Bugcrowd, a platform that helps find and fix vulnerabilities in software products. The program rewards researchers for discovering and reporting security issues, with varying levels of reward based on the severity of the bug. Researchers must submit verifiable evidence to receive recognition or an award, and must use test accounts and systems to avoid affecting real users' security and privacy. Sophos runs a private invite-only bug bounty program with higher risk and complexity applications, and has formalized its approach with Bugcrowd to improve response times and streamline internal processes.
