Zaun Ltd.

Zaun Ltd., operating under the alias Zaun, is a United Kingdom‑based organisation that designs and supplies perimeter fencing products. The company’s core offering consists of fencing solutions intended for security and boundary demarcation across various sectors. Its products are described as publicly visible perimeter fencing, indicating they are used in environments where the fencing itself is observable. Zaun’s headquarters are located in the United Kingdom, which serves as the base for its operational and administrative functions. The organisation serves markets that require physical perimeter protection, though specific industries or geographic reach are not detailed in the available sources.

Zaun distinguishes itself through its focus on manufacturing perimeter fencing, a specialization that relies on dedicated production equipment connected to its network. In August 2023 the company experienced a cyber‑attack carried out by the LockBit ransomware group, which exploited an isolated, outdated Windows 7 PC linked to manufacturing machinery. Although Zaun’s security controls prevented the ransomware from encrypting its servers, the attackers succeeded in exfiltrating approximately ten gigabytes of data, including historic emails, customer orders and project files. The firm has stated that no classified or sensitive documents were compromised and that the stolen information pertains only to its publicly visible perimeter fencing product line. This incident highlights both the organisation’s reliance on legacy equipment for production and the ongoing challenges of securing industrial control systems against ransomware threats.
