The security of our website and your data is our highest priority.
We have therefore temporarily taken the Harren Group website offline as a precaution.
This measure follows the disclosure of critical vulnerabilities in PHP, a widely used technology that also supports our website. The shutdown is preventive and intended to avoid potential security risks while the systems are reviewed and updated.
When will the website be available again?
We are working to restore the website as quickly as possible. Security updates for PHP are scheduled for 21 October 2026. Once they are available, we will install the required updates and complete our security checks.
The Harren Group website will return as soon as those checks have been completed. We cannot yet provide an exact time.
What does this mean for you?
Website content and online functions are temporarily unavailable. This notice concerns only the website and does not affect Harren Group’s operational services.
