Connect to the 'primary security update source' via proxy

You can connect your agents and relays to your 'primary security update source' via a proxy. By default, the 'primary security update source' is the Trend Micro Update Server (also called Active Update).

The agents and appliancesClosedThe Deep Securty Agent and Deep Security Virtual Appliance are the components that enforce the Deep Security policies that you have defined. Agents are deployed directly on a computer. Appliances are used in VMware vSphere environments to provide agentless protection. They are not available with Deep Security as a Service. will only use the proxy if their assigned relay is not available, and they've been granted explicit permission to access the primary update source.

  1. Make sure you're using Deep Security Agent 10.0 or later. Only 10.0 and later supports connections through a proxy.
  2. Register a proxy in the manager.
  3. In Deep Security Manager, click the Administration > System Settings > Proxies tab.
  4. In the Proxy Server Use area, change the Primary Security Update Proxy used by Agents, Appliances, and Relays setting to point to the new proxy.
  5. Click Save.
  6. Restart the agents.

Connect to Deep Security Manager via proxy

Agents connect to their manager during agent activation and heartbeats. There are two methods to connect an agent to its manager via a proxy.

Connect to Deep Security Relays via proxy

Agents connect to their relay to obtain software and security updates. There are two methods to connect an agent to a relay via a proxy.

Connect to Deep Security Software Updates, CSSS, and more via proxy
