January 2020, version 1.0
Are you a security researcher and did you find vulnerabilities in our systems? If so, we would like to cooperate with you to resolve these vulnerabilities before they can be exploited by attackers. Every day, specialists at Rabobank are working hard on improving our systems and processes. By doing this, data from our clients is protected and the availability of our services are secured. This does not mean that our systems are always flawless and free of vulnerabilities, that’s why we would like to cooperate with security researchers who are able to find those vulnerabilities.
You can submit reports regarding security issues on Rabobank services. If you have found a security issue of vulnerability, please report this as soon as possible. Examples are;
- Remote Code Execution
- Cross-Site Scripting (XSS)
- Cross-Site Request Forgery (CSRF)
- SQL Injection
- Encryption vulnerabilities
- Authentication bypasses and unauthorized data access

Rabobank provides domain registration for trusted third parties and subsidiaries. This means domains which are not part of any Rabobank services could have WHOIS information related to the Rabobank and/or use the name servers of Rabobank. Most of these domains are out of scope. We understand that the distinction can be hard so we evaluate them case by case.
We will not reward trivial or non-exploitable bugs. Examples below include known issues and accepted risks:
- HTTP 404 codes/pages or other HTTP non-200 codes/pages
- Fingerprinting / version banner disclosure on common/public services
- Disclosure of know public files, directories or non-sensitive information (e.g. robots.txt)
