CiviProxy is a tool to set up a security proxy server specifically for your CiviCRM instance. It uses whitelisting and parameter sanitation to allow only legitimate requests to pass through.
The documentation on CiviProxy can be found here: https://docs.civicrm.org/civiproxy/en/latest/
This software is provided as Free and Open Source Software, and we are happy if you find it useful. However, we have put a lot of work into it (and continue to do so), much of it unpaid for. So if you benefit from our software, please consider making a financial contribution so we can continue to maintain and develop it further.
If you are willing to support us in developing this tool, please send an email to info@systopia.de to get an invoice or agree a different payment method. Thank you!
