Bij DESAN beschouwen we de beveiliging van onze systemen als van het grootste belang. Ondanks onze beste inspanningen om onze systemen te beveiligen, kunnen er toch kwetsbaarheden bestaan. Als u een beveiligingszwakte ontdekt in een van onze systemen, moedigen wij u aan om dit onmiddellijk aan ons te melden. Deze samenwerking helpt ons om onze klanten en systemen effectief te beschermen.

We kindly request that you:

1. Share your findings with us.

2. Refrain from exploiting the issue, such as downloading more data than necessary to demonstrate the vulnerability, or accessing, modifying, or deleting third-party data.

3. Avoid disclosing the issue to others until it has been resolved. We also ask that you promptly delete any confidential data obtained once the vulnerability is fixed.

4. Do not engage in physical security attacks, social engineering, distributed denial of service attacks, spam, or attacks on third-party applications.

5. Provide sufficient information to reproduce the problem, allowing us to address it as quickly as possible. Typically, the IP address or URL of the affected system, along with a description of the vulnerability, is adequate. However, for more complex vulnerabilities, additional information may be necessary.


In return, we promise:

1. To respond to your report within 5 days, providing an assessment and an expected resolution date.

2. Not to pursue legal action against you if you adhere to the above conditions.

3. To treat your report confidentially and not share your personal information with third parties without your consent unless required by law. You are welcome to report under a pseudonym.

4. To keep you informed about the progress of resolving the issue. If you wish, we will mention your name as the discoverer in our communications about the problem.

5. To strive for swift resolution of all reported issues. We are also open to collaboration on any public disclosure of the problem after it has been resolved.
