System and network requirements
Verify your system and network requirements before you install a DigiCert® sensor.
System requirements
Your environment must have at least a minimal installation of a supported operating system:
Server type | Minimum OS | Minimum settings | Sensor version |
|---|---|---|---|
Docker |
|
Be sure to review the installation considerations. | 3.8.31 |
Windows |
|
| 3.8.31 |
Linux |

| 3.8.31 |
Considerations for installing with Docker
Docker sensor containers use a bridge network by default. This associates the Docker network with a bridge interface on the host, along with firewall rules to filter traffic between these interfaces.
Docker containers that share the same Docker network and host bridge interface but are isolated from each other by a firewall can communicate with each other on the bridge network.
To view a list of Docker interfaces, run the
docker network lscommand.To get information about Docker interfaces, run the
docker inspect <docker_container_ID> | grep sensorcommand.
Network requirements
The sensor must be able to meet the following considerations:
Connect outbound to HTTPS (port 443).
Resolve the fully qualified domain names (FQDNs) for its host system, either via DNS or a local "hosts" file.
Access any external systems that it will integrate with via connectors, or any systems on your network that it will target for certificate lifecycle automation or in network scans.
Access the two DigiCert platform URLs for one of the following regions:
