An agent is a low-footprint, secure application that runs on managed servers. The agent runs as two OS processes: Agent and Agent Shield.
- On Windows, the Agent and Agent Shield run as Windows services.
- On Linux, the Agent and Agent Shield run as OS processes.
Agents can be configured to connect to the cloud in one of the following ways:
- Connect directly
- Connect using proxy
Each Agent connects to the cloud directly over the internet. The direct connection configuration is suitable for small environments that do not have a local gateway deployed.
Connecting using proxy
Each Agent connects to the cloud using a proxy. The gateway includes an embedded proxy and is the recommended proxy for this configuration. An embedded proxy is a Squid proxy server prepackaged with the gateway and by default, the Proxy service in the gateway is turned-off state and you need to start the Proxy service.

When you connect the Agent using a proxy, you avoid opening outbound access for each agent.
Outbound connectivity requirements
|TCP port 443||To connect to the cloud using its public IP addresses, if the agents are configured to connect directly.|
|TCP port 3128||To connect to the cloud, use the proxy server embedded in the gateway.|
