WatchGuard Firebox T20-W Security Appliance with 1YR Total Security Suite

The range of alternating current voltage that the product accepts from its power source, expressed in volts (V). It indicates the minimum and maximum supply voltages compatible with the device across different regions.

A list of software applications, operating systems, drivers, or utilities that are pre-installed or bundled with the product. The values may include antivirus suites, productivity tools, device management utilities, and other essential software components.

The highest count of simultaneous sessions or links that a device can handle without performance degradation. This value indicates how many concurrent connections—such as network sockets, user sessions, or data streams—can be active at the same time.

Indicates whether a device can automatically update its IP address with a Dynamic DNS service, allowing remote access even when the public IP changes.

Represents the total count of Ethernet LAN (RJ‑45) interfaces available on a product. The value is an integer indicating how many physical Ethernet ports are present, regardless of speed or generation.

The maximum rate at which a firewall can process or transmit network traffic, expressed in megabits per second (Mbits/s). It indicates the capacity of the device to handle data flow without bottlenecks.

The altitude interval (in meters) at which a product or component ceases to function correctly due to environmental factors such as reduced atmospheric pressure, temperature changes, or other elevation‑related effects. The value is expressed as a minimum–maximum range and applies to any device that has documented limits for operation above or below certain heights.

The range of altitudes (in meters) at which a product or component can operate reliably without performance degradation due to changes in atmospheric pressure, temperature, or other altitude‑related effects.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

The range of temperatures in which a product can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

A list of cryptographic and authentication methods that a device can use for secure communication or data protection. Each entry represents a distinct algorithm or protocol, such as encryption ciphers (e.g., AES, WEP), authentication mechanisms (e.g., RADIUS, WPA‑PSK), or network security protocols (e.g., HTTPS, SSL/TLS). The values are typically separated by commas and may include both technical identifiers and consumer‑friendly labels.

The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

A list of environmental, safety or quality certifications that a product has obtained from recognized authorities. Typical entries include RoHS, ENERGY STAR, CE, WEEE, TCO Certified, FCC, and other industry‑specific standards.

The total count of USB 3.2 Gen 1 (also known as USB 3.1 Gen 1 or SuperSpeed) ports available on the device, indicating how many peripherals can be connected simultaneously via this interface.

A list of the wireless networking protocols and frequency bands that a device can connect to, such as 802.11a, 802.11b, 802.11g, Wi‑Fi 4 (802.11n), Wi‑Fi 5 (802.11ac) or Wi‑Fi 6 (802.11ax). The values are typically separated by commas and may include both the technical name and a consumer‑friendly label.
