Ubiquiti UniFi Cloud Key Enterprise (CK-Enterprise)

The Ubiquiti UniFi Cloud Key Enterprise (CK-Enterprise) is a powerful UniFi Console designed for managing large-scale UniFi deployments with reliability, redundancy, and performance at its core. Built to support thousands of UniFi devices and clients, the CK-Enterprise is ideal for enterprises, universities, hospitality groups, and service providers seeking centralized control over vast, distributed UniFi networks.

At the core of the CK-Enterprise lies a 16-core Intel® Xeon® Scalable processor (Gold 5218) running at 2.3 GHz. This enterprise-grade CPU is backed by 32 GB of DDR4 ECC RDIMM memory (2× 16 GB), providing ample processing power for running UniFi Network Controller and other UniFi OS applications in parallel. With a built-in 256 GB M.2 2280 SATA SSD, the device offers reliable storage for operating system and application data, ensuring fast access and smooth operation even under heavy workloads.

The Cloud Key Enterprise supports massive scalability, with the capability to manage over 1,000 UniFi Network devices and 10,000+ clients. This makes it suitable for organizations with multiple sites and high device counts, ensuring responsive control and monitoring without cloud dependency or external hosting services.

Connectivity is optimized with one 10G SFP+ port for high-speed uplink and one Gigabit RJ45 port, allowing flexible network integration into existing infrastructures. Dual 550W redundant power supply units (PSUs) ensure high availability, keeping the system operational even if one PSU fails or requires replacement—ideal for mission-critical networks with zero downtime tolerance.

Designed in a 1U rackmount form factor, the CK-Enterprise fits neatly into standard server racks, simplifying deployment in enterprise data centers or network control rooms. The device also includes built-in Bluetooth, allowing rapid initial configuration via the UniFi Mobile App—a convenient feature for on-site installers and IT teams.

Managed through UniFi OS, the Cloud Key Enterprise provides a unified platform for running UniFi Network and other UniFi applications, such as Protect (video surveillance), Talk (VoIP), and Access (door control), depending on organizational needs. The intuitive web-based dashboard makes it easy to onboard devices, configure networks, view performance metrics, and apply security policies—all from a single, central location.

In summary, the Ubiquiti UniFi Cloud Key Enterprise (CK-Enterprise) is an enterprise-grade controller designed to power the largest and most demanding UniFi environments. With its high-performance hardware, redundant power, and 10G networking, it offers scalable, reliable, and secure centralized network management that grows with your infrastructure.
