Sendmarc Breach Detection is a monitoring service that identifies compromised company data by scanning multiple sources, including the dark web, for leaked or stolen information. The service covers three main areas: **Hijacked Credentials & Personal Information** Detects exposed passwords, email addresses, login details, and personal employee information that has been made available on the dark web as a result of a breach. **Device Breaches** Identifies data exfiltrated from malware-infected personal devices used to access work services. This includes data captured by keyloggers and other malware, such as browser history and login credentials. **Breach Visibility for Compliance** Provides visibility into breaches affecting the business, including those originating from internal systems or third-party service providers. This supports compliance with regulations such as HIPAA, GDPR, and POPIA, which require suppliers to notify customers of breaches. The service performs regular checks and sends alerts once notifications are configured. It also displays the sources of detected breaches, enabling businesses to assess and respond to incidents more effectively.
