# Security and Compliance at Husk

> Husk is built on regulated financial infrastructure with real-time monitoring, 3D Secure, dynamic risk assessment, and full PSD2 and GDPR compliance.

Husk is built on regulated financial infrastructure and pairs it with real-time controls so your team can move fast without exposing the company to unnecessary risk. Cards are issued under a licensed European e-money institution, and every transaction runs through Husk's monitoring engine.

## How your funds are protected

* **Card issuance**: Stripe Technology Europe Limited, authorized by the Central Bank of Ireland (firm reference C187865) under the Mastercard scheme
* **PSD2 compliance**: bank connections use secure open-banking APIs with Strong Customer Authentication
* **GDPR**: your data is processed in the EU and covered by strict retention and access controls
* **Encryption**: all data in transit and at rest is encrypted with industry-standard ciphers

  <Card title="Transaction Monitoring" icon="eye" href="/security/transaction-monitoring">
    24/7 real-time monitoring that flags rogue spend and budget leaks as they happen.
  </Card>
</CardGroup>

## Dynamic risk assessment

Every card and account gets a risk score that updates as spending patterns evolve. Unusual transactions (new merchant, uncommon geography, spike in amount) trigger a review before they clear, reducing fraud without slowing down normal spend.

<Tip>
  Combine 3D Secure with per-card spending controls to make out-of-policy charges structurally impossible. See [Spending Controls](/cards/spending-controls).
