Griesser AG, also known by its alias, is a manufacturer of window treatments with its headquarters located in Switzerland. The company focuses on the production of products classified as window treatments for use in building applications.

On 14 April 2021, Griesser AG was the target of a ransomware attack that specifically aimed at its servers. The attack disrupted operations at production facilities situated in Switzerland, Austria and France. The interruption affected manufacturing processes across these three countries during the incident.

Communication with partners and customers was restricted to telephone and email channels during the disruption.

Griesser AG stated that it had been prepared for such scenarios but did not confirm whether any customer, partner or employee data had been compromised. No details regarding the ransomware variant used or any potential ransom demand were disclosed publicly. The organization emphasized that the incident was managed through its existing contingency procedures.

The ransomware event was reported by public sources, including a databreaches.net article, and remains the only publicly documented security incident involving the company. No further technical specifics or follow‑up actions have been made available in the disclosed information.
