Port numbers, URLs, and IP addresses

Deep Security default port numbers, URLs, IP addresses, and protocols are listed in the sections below. If a port, URL or IP address is configurable, a link is provided to the relevant configuration page.

If your network uses a proxy or loadbalancer, you can configure Deep Security to use it instead of the default ports and URLs listed on this page. For details, see Proxy settings and Load Balancers.

In addition to the ports on this page, Deep Security uses ephemeral ports when opening a socket (source port). Under rare circumstances these may be blocked, causing connectivity issues. For details, see Activation Failed - Blocked port.

Deep Security port numbers

Port type Default port number
Manager listen ports
  • 443/HTTPS (Deep Security AMI from AWS Marketplace listen port)
  • 4120/HTTPS (Deep Security Manager heartbeat port)
  • 8080/HTTP (AWS web installer port)
Manager destination ports
  • 25/SMTP* (email server port)
  • 53/DNS (DNS server port)
  • 80/HTTP, 443/HTTPS (these ports are used by various Deep Security cloud services, Smart Protection Network services, Whois server, AWS, and Azure)
  • 123/NTP* (NTP server port; the NTP server can be Trend Micro Control Manager)
  • 162/SNMP* (SNMP manager port)
  • 389/LDAP, 636/LDAPS* (Active Directory)
  • 514/Syslog* (SIEM or syslog server port)
  • 1433/SQL (Microsoft SQL database port)
  • 1521/SQL (Oracle database port)
  • 5432/SQL (PostgreSQL database port)
  • 4118/HTTPS* (Deep Security Agent port)
  • 4122/HTTPS (Deep Security Relay port)

* Notes:

Deep Security Agent listen port
  • 4118/HTTPS (Agent listen port for heartbeats)

4118 can be closed if you are using agent-initiated communication. By default, bidirectional communication is used, so 4118 must be opened. See Agent-manager communication for details.

Deep Security Agent destination ports
  • 53/DNS (DNS server port)
  • 80/HTTP, 443/HTTPS (Smart Protection Network portDeep Security Manager port,)
  • 123/NTP* (NTP server port)
  • 514/syslog* (SIEM or syslog server port)
  • 4120/HTTPS* (Deep Security Manager heartbeat port)
  • 4122/HTTPS (Deep Security Relay port)
  • 5274/HTTP, 5275/HTTPS* (Smart Protection Server ports)

* Notes:

Deep Security Relay listen ports
  • Open all the agent listen ports, since they apply to the relay as well
  • 4122/HTTPS (relay port)
  • 4123 (port for communication between the agent and its own internal relay)

4123 should not be listening to connections from other computers, and you don't need to configure it in network firewall policies. But if you have firewall software (such as Windows Firewall or iptables) on the manager's server itself, verify that it does not block this connection to itself. Also verify that other applications do not use the same port (a port conflict).

Deep Security Relay destination ports
  • 80/HTTP, 443/HTTPS (Trend Micro Update Server/Active Update and Download Center ports)
  • 4122 (port of other relays)

Deep Security URLs

If you need to restrict the URLs that are allowed in your environment, read this section.

You'll need to make sure your firewall allows traffic to the following Trend Micro, Deep Security, AWS, and Azure server URLs on port 443 (HTTPS) and port 80 (HTTP).

AWS and Azure URLs

Used for
adding AWS accounts and Azure accounts to Deep Security Manager.



  • URLs of AWS EC2 endpoints. For the endpoint URL names, see this AWS page.

Azure URLs

  • login.windows.net (authentication)
  • management.azure.com (Azure API)
  • management.core.windows.net (Azure API)
  • azureconnector.deepsecurity.trendmicro.com (Azure connector 'Quick' option)

The management.core.windows.net URL is only required if you used the v1 Azure connector available in Deep Security Manager 9.6 to add an Azure account to the manager. With Deep Security Manager 10.0 and later, a v2 connector is used, and does not require access to this URL.
