Datadog has partnered with GitHub and GitGuardian to protect its customers' accounts from leaked credentials, which are a major cause of data breaches. Datadog uses regular expressions and detection rules to identify potential leaked credentials in public repositories, and notifies users as soon as it detects a leak. Once notified, users can take immediate action to limit the impact of the leak by revoking the key and reviewing their account for suspicious activity. To prevent leaks from occurring in the first place, Datadog recommends best practices such as defining scopes for application keys, using service accounts, revoking unused API keys, and creating multiple API keys for different purposes. By implementing these strategies, users can safeguard their data and reduce the risk of unauthorized access to their accounts.
