The DigiCert® sensor software is DigiCert’s native gateway application for enabling network-based integrations, discovery, and automation. You need at least one sensor installed on your network to use the following features in DigiCert® Trust Lifecycle Manager:
You install the sensor on-premises for security and performance reasons. DigiCert sensors use a pull communication model to synchronize with Trust Lifecycle Manager over outbound port 443 (HTTPS). They do not require inbound access. Each sensor can keep itself updated as new software versions get released to reduce the need for ongoing maintenance.
