Responsible Disclosure Policy

At Pro4all the security of our systems is extremely important.

Despite our concern for the security of our systems during product development and maintenance, it could still be that a weak point exists.

We appreciate you notifying us if you found a weak point in one of our systems as soon as possible so that we can take measures immediately to protect our customers and their data.

How to report?

If you believe you found a security issue in one of our systems, please notify us as soon as possible by emailing us at


This responsible disclosure policy is not an open invitation to actively scan our network and applications for vulnerabilities. Our continuous monitoring will likely detect your scan and these will be investigated.

We ask you to:

  • Not share information about the security issue with others until the problem is resolved and to immediately delete any confidential data acquired
  • Not further abuse the problem, for example, by downloading more data than is necessary in order to demonstrate the leak or to view, delete or amend the data of third parties
  • Provide detailed information in order for us to reproduce, validate and resolve the problem as quickly as possible. Include your test data, timestamps and URL(s) of the system(s) involved
  • Leave your contact details (e-mail address and/or phone number) so that we may contact you about the progress of the solution. We do accept anonymous reports
  • Do not use attacks on physical security, social engineering, distributed denial of service, spam or applications of third parties

How Pro4all handles Responsible Disclosure

When you report a security issue, we will act according to the following:

  • You will receive a confirmation of receipt from us within 10 working days after the report was made
  • You will receive a response with the assessment of the security issue and an expected date of resolution within 10 working days after the confirmation of receipt was sent
  • We will take no legal steps against you in relation to the report if you have kept to the conditions as set out above
  • We will handle your report confidentially and we will not share your details with third parties without your permission, unless that is necessary in order to fulfil a legal obligation

Bug bounty program

Pro4all  encourages the reporting of security issues or vulnerabilities. We may make an appropriate reward for confidential disclosure of any design or implementation issue that could be used to compromise the confidentiality or integrity of our users’ data that was not yet known to us. We decide whether the report is eligible and the amount of the reward.


The following type of security problems are excluded

  • (D)DOS attacks
  • Error messages or error pages without sensitive data
  • Vulnerability scan reports for software we publicly use
  • Security issues related to outdated OS’s, browsers or plugins
  • Reports for security problems that we have been notified of before

Please note: Reports that are lacking any proof (such as screenshots or other data), detailed information or details on how to reproduce any unexpected result will be investigated but will not be eligible for any reward.

This policy is based on the National Cyber Security Centre’s Responsible Disclosure Guidelines
