Prepare your environment before installing a Sensor Gateway. What to read next Set Up Your EnvironmentTo ensure a successful installation of the Sensor Gateway appliance, you must perform some required tasks and pre-checks before running the installer. Provision Sensor Gateway API KeyYou must generate an API key from the Carbon Black Cloud console and use the generated API key to establish a connection between the Carbon Black Cloud console and the Sensor Gateway deployed in the vCenter Server. If you are configuring multiple Sensor Gateways, generate a separate API key for each instance. Carbon Black Cloud AccessYou must configure your firewall-protected network to allow connection to the following environment-specific URLs. Sensor Gateway Certificates A Carbon Black sensor talks to the Sensor Gateway through a certificate. The Sensor Gateway can run on both CA-signed certificate and self-signed certificate. Carbon Black recommends using the CA-signed certificates so you can install all needed certificates on all Sensor Gateway servers at once instead of installing the trusted certificate on each machine individually. Create a Certificate Chain FileCarbon Black uses a certificate chain file to perform a proper OCSP stapling. Parent topic: Installing and Using Carbon Black Sensor Gateway
