Responsible Disclosure Policy


Babylon takes the protection of our members’ health information very seriously. We use a Secure Software Development Lifecycle process to ensure that security and data protection are at the heart of our information governance programme. We always seek to improve what we do and feedback from our users is especially important to us. We value the responsible disclosure of security vulnerabilities carried out by well-intentioned and ethical security researchers. This helps us to keep information safe and improve our business.

We would ask researchers to please not publicly disclose details of vulnerabilities without contacting Babylon first, so that we can ensure our users’ sensitive information is protected.


  • If you have found a potential vulnerability (that fits within the notification criteria listed below) please tell us about it, by emailing us at:
  • You can expect to receive acknowledgement from the Babylon security team within 48 hours of your submission
  • Babylon does not provide submitters with financial rewards
  • Guidelines for the type of testing allowed cannot modify or destroy any personal data other than your own, and cannot violate any of Babylon’s or its partners’ Privacy Policies
  • Babylon will investigate your responsible disclosure submission findings and the priority for fixes and/or mitigations will be assigned based on severity classification, impact and ease of exploitation
  • We will provide feedback on the outcome of our investigation privately and confidentially to the submitter
  • Upon validating an issue, Babylon will remediate in a timely manner, in accordance with our relevant security policies
  • Babylon will notify the submitter once the vulnerability is remediated
  • All disclosures must be made following Babylon’s Responsible Disclosure Program Policy
  • We would ask anyone not to report vulnerabilities publicly (for example to the press or within a social media stream or other public domain) due to the potential impact this could have on our users. We would consider this irresponsible disclosure and ask for the chance to fix any vulnerabilities before announcements are made public.

Acceptable scope and guidelines

We may make changes to our Responsible Disclosure Programme so please visit frequently to keep up-to-date and ensure you stay within its scope.

Disclosure reporting guidelines
