Committed to protecting your data.

While the phrase bank-level security is widely used across the internet these days, it doesn't mean much without a description of what a company is doing under-the-hood. We will be transparent and upfront about how we secure your data.

    Bank-Level Security

    We strive to meet and exceed the best security practices using layers of protection and bank-level standards.

Security Expertise

Security is one of the biggest considerations in everything we do. At Greenback, security begins with the people engineering our product. Our executive team has years of experience founding and managing companies across the payment and telecommunications industries — which have strict security and compliance requirements.

HTTPS and HSTS for secure connections

Greenback forces HTTPS for all services using TLS (SSL), including our public website and the Dashboard. When interacting with third-party providers such as Intuit, QuickBooks, Amazon, Gmail, etc. we connect over TLS and verify TLS certificates on each connection.

  • We regularly audit the details of our implementation: the certificates we serve, the certificate authorities we use, and the ciphers we support.
  • We use HSTS to ensure browsers interact with Greenback only over HTTPS. Greenback maintains the highest level TLS rating per Qualys.

Encryption of Sensitive Data

All sensitive data (such as credentials to third parties) at Greenback is encrypted on disk with AES-256. Master decryption keys are not permanently stored on any machine and must be manually supplied if we need to restart a handful of critical internal services.

  • None of Greenback’s public-facing servers and daemons are able to obtain plaintext sensitive data.
  • Greenback’s infrastructure for storing, decrypting, and transmitting sensitive data runs in separate hosting infrastructure, and doesn’t share any credentials with Greenback’s primary services (API, website, etc.).
