Security, data & compliance

How we protect your data, our approach to UK GDPR, connecting to HMRC safely, and how to report a security issue.

How your data is protected

  • Data is encrypted in transit (TLS), and sensitive credentials — including HMRC access tokens — are encrypted at rest.
  • Each customer’s data is logically separated so it cannot be accessed by other customers.
  • Access to production data is restricted on a least-privilege, role-based basis.
  • Valix connects to HMRC using OAuth 2.0, so your Government Gateway password is never stored.

UK GDPR & your data

You control your data. You can export your records, and you can request deletion. Our Privacy Policy explains what we collect, why, and your rights under UK data-protection law.

Reporting a security issue

If you believe you have found a vulnerability, please tell us so we can investigate and fix it. Our full responsible-disclosure process and machine-readable contact details are on the Security page.
