    1. Security update successfully completed – Trenda is available again

      Today, October 21, 2026, at approximately 4:00 p.m., security updates were released for PHP, a widely used technology on which a large portion of the world’s websites are based. The updates address a critical vulnerability that was recently discovered.

      We responded immediately after the release and took Trenda offline as a precaution. We then installed the security updates, carefully checked our systems, and brought the platform back online shortly thereafter.

      Trenda has been fully available again since 5:30 p.m. The temporary shutdown was purely a precautionary measure to ensure the security of our platform and customer data at all times.

      The security of our platform is our top priority. That’s why we continuously monitor relevant security alerts and implement important updates as quickly as possible.

      If you have any questions, you can reach us at support@trenda.ch.
