Vulnerability disclosure program

The security of our online systems and the information they hold are our highest priority. We take every care to ensure that they are secure and up to date. However, we recognise that despite these efforts there may still be vulnerabilities.

We welcome engagement from the security community and we are grateful for anyone sharing their findings with us to make our system, security even stronger. Our security vulnerability program provides an avenue for you to responsibly report any potential issues or vulnerabilities with us.

If you are a supplier and you would like to make an enquiry relating to a procurement process with the Tax Ombudsman or a government procurement complaint, please email us and it will be assigned to the appropriate area.
