Tanium Appliance specifications
Review the Tanium Appliance specifications to ensure support with your environment. For more information, see Reference: Tanium Appliance specifications.
Tanium Appliance software versions
The TanOS version is the version of the appliance operating system and menus. The appliance operating system is updated periodically to support new features and to support new Tanium Core Platform features.
The Tanium Core Platform version is the version of the platform server component. All components must run the same build version. The TanOS distribution includes installers for supported Tanium Core Platform versions. In Tanium Appliance deployments, support for a Tanium Core Platform release might require a TanOS upgrade. For more information, see the TanOS Release Notes for your release.
The connections to the Tanium Console or SOAP and REST APIs, the connections between the Tanium Server and the Tanium Module Server, and connections to the Module Server are secured with SSL/TLS certificate and key exchanges. The installation process uses self-signed certificates. For best results, verify the installation with the self-signed certificates before you replace them with your commercial or enterprise certificates signed by a Certificate Authority. Doing this facilitates troubleshooting by separating potential installation issues and SSL issues.
For more information on SSL certificate requirements, see the Tanium Core Platform Deployment Reference Guide: SSL certificates.
Network connectivity and firewall
Tanium components use TCP/IP to communicate. You must work with your network administrator to ensure that the Tanium components are provisioned IP addresses and that DNS can be used to resolve host names.
The Tanium Server must be able to connect to the Tanium database server and Module Server. In a redundant cluster, the Tanium Servers must be able to connect to each other over a reliable Ethernet connection. These connections require a minimum throughput of 1 Gbps and a maximum round-trip latency of 30 ms.
The following table summarizes the Tanium processes and default values for ports used in Tanium core platform communication. You might need to configure network firewalls to allow the specified processes to send/receive TCP packets through the ports listed. For a detailed explanation, see Tanium Core Platform Deployment Reference Guide: Network ports.
|Tanium Clients||Tanium Server||17472||TCP||Client communication with the Tanium Server|
|Tanium Module Server||Tanium Server||443, 8443||TCP||Tanium Module Server communication to the Tanium Server|
|Console users||Tanium Server||443, 8443||TCP||Tanium Console communication with the Tanium Server|
|Tanium Server||Tanium Module Server||17477||TCP||Tanium Module Server communication from Tanium Server|
|Tanium Zone Server Hub||Tanium Zone Server||17472||TCP||Tanium Zone Server Hub communication with the Tanium Zone Servers|
|External servers||443, 80||TCP||Tanium Server or Module Server communication with external servers such as content.tanium.com|
In addition, the installation and management of the appliance requires communication over common network service ports. The following table shows the default ports for these services.
Tanium Module Servers
|DNS servers||53||UDP, TCP||DNS resolution for Tanium Servers and Tanium Module Servers|
|Tanium Servers||Not applicable||IPsec ESP1||Protocol for data confidentiality and authentication in Tanium Server cluster communications|
|Tanium Module Servers||Tanium Module Servers||Not applicable||IPsec ESP1||
Protocol for data confidentiality and authentication during Tanium Module Server synchronization
|Tanium Servers||500, 4500||UDP||IPsec IKE for setting up a secure channel in Tanium Server cluster communications|
|Tanium Module Servers||Tanium Module Servers||500, 4500||UDP||IPsec IKE for setting up a secure channel during Tanium Module Server synchronization|
|Tanium Servers||LDAP servers||389, 636||TCP||(Optional) External LDAP communications for Tanium authentication|
|All Tanium Appliances||NTP servers||123||UDP||NTP time synchronization|
|Tanium Servers||All Tanium Appliances||22||TCP||SSH, SCP, SFTP communication for appliance array management|
|Tanium administrator workstations||All Tanium Appliances||22||TCP||SSH, SCP, SFTP communication for appliance management|
|SNMP servers||Tanium Appliances||161||UDP||(Optional) SNMP monitoring|
|Tanium Appliances||Syslog servers||514||TCP, UDP||(Optional) Syslog monitoring|
|Tanium administrator workstations||Tanium Appliances||443, 5900||TCP||(Physical appliances only) iDRAC communications2|
|Tanium Console user workstations/browsers||content.tanium.com
|80, 443||TCP||Download and install solutions to the Tanium Core Platform|
|Tanium Appliances||download.tanium.com||443||TCP||(Optional) Download and install Tanium Server upgrades.|
1 IPSec ESP is not a port. For Appliance Array traffic to properly work, you must add custom exceptions to your firewall rules.
2 These ports need to be open only for the IP address of the dedicated iDRAC port (if applicable). The iDRAC port has an IP address that is different from the TanOS network interfaces. See
Do not allow a Tanium Server, a Module Server, or a Zone Server Hub to accept inbound connections from the internet. On a Zone Server, allow only the Tanium Client port to accept inbound connections from the internet.
The following figure illustrates how the Tanium Core Platform uses ports in an active-active deployment with Appliance infrastructure.
Tanium™ Direct Connect uses additional ports for communication between Tanium Clients and the Module Server. See Tanium Direct Connect User Guide: Host and network security requirements.
For more information about the port requirements of other Tanium modules and shared services, see
Configure firewall policies to open ports for Tanium traffic with TCP-based rules instead of application identity-based rules. For example, on a Palo Alto Networks firewall, configure the rules with service objects or service groups instead of application objects or application groups.
Internet access (direct or by proxy)
During both installation and ongoing operations, the Tanium Server must be able to access specific Internet URLs to import updates to Tanium core components and modules. For a list of URLs, see Tanium Core Platform Deployment Reference Guide: Internet URLs required.
If your enterprise network environment requires outbound Internet connections to traverse a proxy server, you can configure settings used to traverse the proxy server. For guidelines on proxy settings, see Tanium Core Platform Deployment Reference Guide: Proxy server settings.
If you plan to deploy Tanium into an air-gapped environment, see Reference: Air gap support.
