Supported Operating Systems for the Carbon Black Cloud Sensor

For a complete list of supported operating systems, see the following sensor OERs:

Supported Browsers for the Carbon Black Cloud Console

Windows: Firefox, Chrome, and Edge
macOS: Safari, Firefox, and Chrome

Linux 4.4+ Kernels for Linux Sensor 2.10+

Prior to installing the sensor, the underlying BPF implementation requires the Linux kernel headers for the active kernel to be installed.

See Linux Kernel Requirements for Linux Sensor Versions 2.10+ .

macOS User Space Functionality

Beginning in macOS 11, the Carbon Black Cloud macOS sensor (v3.5.1) operates by default in user-space via System Extensions (user-space) instead of Kernel Extensions (KEXTs) that are used in prior versions of the agent. Therefore, there are some functional differences when using the sensor in System Extension mode on macOS 11 and later.

Using the sensor in KEXT mode achieves the same functionality on macOS 11 as it does on older operating systems.

Unless otherwise specified, documentation related to macOS functionality on the Carbon Black Cloud pertains to macOS 10.15 and earlier or to functionality delivered via the KEXT on macOS 11.

The following matrix outlines macOS functionality on the Carbon Black Cloud. The functionality detailed in the macOS 11+ column pertains to the sensor’s functionality in user space (System Extension) in the initial macOS 11-compatible sensor release (v3.5.1+). For functionality provided via the kernel extension, refer to the macOS 10.12 - 11+ column.

Sensor Hardware Requirements

Endpoints must be in compliance with all hardware requirements for the host operating system.

Consider all processes that run on the endpoints when determining your hardware configuration. We recommend a multi-core CPU for all installations.

The following metrics represent system requirements against a minimum environment, which is defined in the context as a user level system (such as an inactive laptop).
