Talend, a leader in data integration and integrity solutions, faced significant challenges with infrastructure credentials and secrets leaking through GitHub, an issue identified by CISO Anne Hardy upon her arrival in 2020. Despite initial attempts to address the problem with an in-house tool, Talend recognized its limitations and sought a more effective market solution, eventually adopting GitGuardian's GitHub public monitoring solution. This decision enabled rapid remediation of past incidents and comprehensive monitoring of both company and personal developer repositories, revealing that the majority of leaks originated from personal code repositories. After extensive training of their 400 developers and implementing a new procedure for handling leaks, Talend successfully cleaned up past issues within three months. GitGuardian now provides real-time alerts, allowing Talend to continuously monitor all code commits and address credential leaks swiftly. The company plans to expand the use of GitGuardian to security champions within its team to ensure ongoing adherence to best practices.
