Configure proxies

Register a proxy in Server & Workload Protection

1. In the Server & Workload Protection console, go to Administration > System Settings > Proxies.
2. In the Proxy Servers area, click New → New Proxy Server.
3. In the Name and Description fields, enter a friendly name and description for your proxy.
4. For the Proxy Protocol, select either HTTP, SOCKS4, SOCKS5, or Proxy Auto-Configuration (PAC). Not all protocols are supported by all components. See Supported proxy protocols for details.

Note The proxy in the PAC file only supports HTTP and direct connection PACs.

1. In the Address and Port fields, enter the IP address or URL of the proxy as well its port (by default 8080 or 80 for HTTP; 3128 for the Squid HTTP proxy; 443 for HTTPS; and 1080 for SOCKS 4 and 5).
2. Enable Proxy requires authentication credentials if you previously set up your HTTP or SOCKS 5 proxy to require authentication from connecting components. Enter those credentials in the User Name and Password fields.

Supported proxy protocols

Connect to the 'primary security update source' via proxy

Note The primary security update source for the new improved relay is the Server & Workload Protection relay. Deep Security Agent 20.0.0-3964+ can connect to Server & Workload Protection relays via this proxy setting.

Note The agents and appliances 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 agent version 10.0 or later. Only 10.0 and later supports connections through a proxy
2. Register a proxy in Server & Workload Protection.
3. In the Server & Workload Protection console, 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 Server & Workload Protection via proxy

Connect an agent to Server & Workload Protection via a proxy using a deployment script

1. Make sure you're using agent version 10.0 or later. Only 10.0 and later supports connections through a proxy.
2. Register a proxy in Server & Workload Protection.
3. In the top right-hand corner of the Server & Workload Protection console, click Administration → Updates → Software → Local → Generate Deployment Scripts.
4. From Proxy to contact Server & Workload Protection, select a proxy.
5. Copy the script or save it.
6. Run the script on the computer. The script installs the agent and configures it to connect to Server & Workload Protection through the specified proxy.

Connect an agent to Server & Workload Protection via a proxy using dsa_control

cd C:\Program Files\Trend Micro\Deep Security Agent\
dsa_control -u myUserName:MTPassw0rd
dsa_control -x dsm_proxy://squid.example.com:443

/opt/ds_agent/dsa_control -u myUserName:MTPassw0rd
/opt/ds_agent/dsa_control -x dsm_proxy://squid.example.com:443

• Make sure the proxy uses a supported protocol. See Supported proxy protocols.
• For details on dsa_control and its -u and -x options, see dsa_control.
• Repeat these commands on each agent that needs to connect through a proxy to Server & Workload Protection.
• Run the following commands to update the agent's local configuration.

Connect to relays via proxy

Connect an agent to relays via a proxy using a deployment script

1. Make sure you're using agent version 10.0 or later. Only 10.0 and later supports connections through a proxy.
2. Register a proxy in Server & Workload Protection.
3. In the top right-hand corner of the Server & Workload Protection console, click Administration → Updates → Software → Local → Generate Deployment Scripts.
4. From Proxy to contact Relay(s), select a proxy.
5. Copy the script or save it.
6. Run the script on the computer. The script installs the agent and configures it to connect to the relay through the specified proxy.

Connect an agent to relays via a proxy using dsa_control

cd C:\Program Files\Trend Micro\Deep Security Agent\
dsa_control -w myUserName:MTPassw0rd
dsa_control -y relay_proxy://squid.example.com:443

/opt/ds_agent/dsa_control -w myUserName:MTPassw0rd
/opt/ds_agent/dsa_control -y relay_proxy://squid.example.com:443

• Make sure the proxy uses a supported protocol. See Supported proxy protocols.
• For details on dsa_control and its -u and -x options, see dsa_control.
• Repeat these commands on each agent that needs to connect through a proxy to Server & Workload Protection.
• Run the following commands to update the agent's local configuration.

Connect to Server & Workload Protection/Relays via Proxy Auto_Configuration (PAC) proxy

1. Ensure you're using agent version 20.0.0-6680 or newer. Only 20.0.0-6680 and newer supports connections through a PAC-resolved proxy.
2. Register the proxy in Server & Workload Protection.
3. In the top right-hand corner of the Server & Workload Protection console, click Administration → Updates → Software → Local → Generate Deployment Scripts.
4. From Proxy to contact Server & Workload Protection/Relay, select a proxy.
5. Copy the script or save it.
6. Run the script on the computer. The script installs the agent and configures it to connect to Server & Workload Protection/Relay through the PAC-resolved proxy.

cd C:\Program Files\Trend Micro\Deep Security Agent\
dsa_control --pacproxyunpw myUserName:MTPassw0rd
dsa_control --pacproxy http://pac.example.com:80/proxy.pac

/opt/ds_agent/dsa_control --pacproxyunpw myUserName:MTPassw0rd
/opt/ds_agent/dsa_control --pacproxy http://pac.example.com:80/proxy.pac

Note Make sure the proxy uses an HTTP protocol. Currently, the PAC-resolved proxy supports the HTTP method only. For details on dsa_control and its --pacproxy and --pacproxyunpw options, see dsa_control. Repeat these commands on each agent that needs to connect through a proxy to Server & Workload Protection/Relay. Run the commands to update the agent's local configuration. The PAC proxy function is supported using a deployment script on Windows only.
