Upon receipt of a suspected security issue report, an automatic acknowledgement shall be sent advising that a response should be expected within 3 working days.

If the security issue is confirmed, we will come back to you with an estimate of how long the issue will take to fix. Once the fix is available, we will notify you and recognise your efforts on this page.
