Aspects of the disclosure relate to monitoring source code repository data in real-time to protect sensitive information and provide entity-specific alerts. A computing platform may receive configuration information defining one or more criteria for identifying sensitive data of an enterprise organization. The computing platform may monitor external code repository server infrastructure based on the configuration information. In response to detecting that first source code received by the external code repository server infrastructure contains first sensitive information associated with the enterprise organization, the computing platform may generate a notification comprising information indicating that the first sensitive information associated with the enterprise organization has been detected at the external code repository server infrastructure. Subsequently, the computing platform may send the notification to an enterprise administrator user computing device associated with the enterprise organization.
