Reveal requirements

Review the requirements before you install and use Reveal.

Review the requirements before you use Reveal.

Core platform dependencies

Make sure that your environment meets the following requirements:

Tanium license that includes Reveal
Tanium™ Core Platform servers: 7.3.314.4250 or later
Tanium™ Client: Any supported version of Tanium Client. For the Tanium Client versions supported for each OS, see Tanium Client Management User Guide: Client version and host system requirements.
If you use a client version that is not listed, certain product features might not be available, or stability issues can occur that can only be resolved by upgrading to one of the listed client versions.

Computer group dependencies

When you first sign in to the Tanium Console after a fresh installation of Tanium Server 7.4.2 or later, the server Tanium™ Cloud automatically imports the computer groups that Reveal requires:

All Computers
All Windows
All Mac
All Linux

For earlier versions of the Tanium Server, or after upgrading from an earlier version, you must manually create the computer groups. See Tanium Console User Guide: Create a computer group.

Solution dependencies

Other Tanium solutions are required for Reveal to function (required dependencies) or for specific Reveal features to work (feature-specific dependencies). The installation method that you select determines if the Tanium Server automatically imports dependencies or if you must manually import them.

Some Reveal dependencies have their own dependencies, which you can see by clicking the links in the lists of Required dependencies and Reveal requirements. Note that the links open the user guides for the latest version of each solution, not necessarily the minimum version that Reveal requires.

Tanium recommended installation

If you select Tanium Recommended Installation when you import Reveal, the Tanium Server automatically imports all your licensed solutions at the same time. See Tanium Console User Guide: Import all modules and services.

Import specific solutions

If you select only Reveal to import and are using Tanium Core Platform 7.5.2.3531 with Tanium Console 3.0.72 or later, the Tanium Server automatically imports the latest available versions of any required dependencies that are missing. If some required dependencies are already imported but their versions are earlier than the minimum required for Reveal, the server automatically updates those dependencies to the latest available versions.

If you select only Reveal to import and you are using Tanium Core Platform 7.5.2.3503 or earlier with Tanium Console 3.0.64 or earlier, you must manually import or update required dependencies. See Tanium Console User Guide: Import, re-import, or update specific solutions.

Required dependencies

Reveal has the following required dependencies at the specified minimum versions:

Tanium Client Index Extension 2.5.13 or later
Tanium Direct Connect 1.4.0 or later
Tanium Endpoint Configuration 1.2 or later (installed as part of Tanium Client Management 1.5 or later)
Tanium Interact 2.5.146 or later
Tanium Trends 3.6.331 or later

Tanium Threat Response™ 3.4.346 or later is required if Threat Response exists in the same environment. Threat Response is not a required Reveal dependency.

Client extensions

Tanium Endpoint Configuration installs client extensions for Reveal on endpoints. Client Extensions perform tasks that are common to certain Tanium solutions. The Tanium Client uses code signatures to verify the integrity of each client extension prior to loading the extension on the endpoint. Each client extension has recommended security exclusions to allow the Tanium processes to run without interference. See Security exclusions for more information. The following client extensions perform Reveal functions:

Core CX - Provides a management framework API for all other client extensions and exposes operating system metrics. Tanium Client Management installs this client extension.
Config CX - Provides installation and configuration of extensions on endpoints. Tanium Client Management installs this client extension.
DEC CX - Provides a direct connection between endpoint and Module ServerTanium Cloud. Tanium Direct Connect installs this client extension.
Index CX - Provides the ability to index the local file systems on endpoints. Tanium Reveal or Tanium Threat Response installs this client extension.
Py CX - Provides a library that enables communication between Python-based client extensions and Core CX. Tanium Integrity Monitor, Tanium Reveal, or Tanium Threat Response installs this client extension.
Reveal CX - Provides distributed keyword and pattern searching capability against content on disk. Tanium Reveal installs this client extension.

Reveal deploys the Tanium Client Index Extension tools, if necessary, and starts the indexing process. Additionally, Reveal deploys a default Index configuration. Ensure that any file types or directories that you expect Reveal to scan are not excluded from hashing. By default, the following directories are excluded from hashing:

^/Library/Tanium/TaniumClient/ (macOS)
^/opt/Tanium/TaniumClient/ (Linux)
\\Tanium\\Tanium Client\\ (Windows)

Tanium Module Server

Reveal is installed and runs as a service on the Tanium Module Server. The impact on the Module Server is minimal and depends on usage.

Endpoints

Supported operating systems

Operating system	Version	Notes
Microsoft Windows Server	Windows Server 2008 R2 SP1 or later	Windows Server 2008 R2 SP1 requires Microsoft KB2758857.
Microsoft Windows Workstation	Windows 11 Windows 10 Windows 8 Windows 7 SP 1	Windows 7 Service Pack 1 requires Microsoft KB2758857.
macOS (Intel processor only)	Same as Tanium Client support	For Tanium Client operating system support, see Tanium Client Management User Guide: Client version and host system requirements

Disk space requirements

Up to 2 GB of free disk space is required on each endpoint.

Host and network security requirements

Specific ports and processes are needed to run Reveal.

Ports

The following ports are required for Reveal communication.

Source	Destination	Port	Protocol	Purpose
Tanium Client (internal)	Module Server	17475	TCP	Used by the Module Server for endpoint connections to internal clients.
Tanium Client (external)	Zone Server* Tanium Cloud	17486	TCP	Used by the Zone Server for endpoint connections to external clients. The default port number is 17486. If needed, you can specify a different port number when you configure the Zone Proxy. Used for endpoint connections.
Module Server	Module Server (loopback)	17470	TCP	Internal purposes, not externally accessible
Module Server	Zone Server*	17487	TCP	Used by the Zone Server for Module Server connections. The default port number is 17487. If needed, you can specify a different port number when you configure the Zone Proxy.
Module Server	Zone Server*	17488	TCP	Allows communication between the Zone Server and the Module Server. On TanOS, the Direct Connect Zone Proxy installer automatically opens port 17488 on the Zone Server. This port must be manually opened on Windows.
*These ports are required only when you use a Zone Server.

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.

Security exclusions

If security software is in use in the environment to monitor and block unknown host system processes, Tanium recommends that a security administrator create exclusions to allow the Tanium processes to run without interference. The configuration of these exclusions varies depending on AV software. For a list of all security exclusions to define across Tanium, see Tanium Core Platform Deployment Reference Guide: Host system security exclusions.
