Basis Theory was built for Enterprise-grade resilience, with a clear focus on eliminating any single point of failure across the payments stack. Basis Theory is designed as an extension of your infrastructure, giving you:

• Enterprise-grade resilience
• No dependency on a single system
• Full PCI compliance without the burden

In payments, no system is immune to failure: processors, gateways, and infrastructure providers can all experience downtime.

Our architecture and product design ensure one simple outcome:

You never miss a payment.

Below are the core mechanisms that ensure you never miss a payment — even in the rare event of an outage.

How We Eliminate SPoF

We approach resilience across two critical layers:

1. Card Capture (Frontend / CITs)
2. Payment Execution (Backend / MITs)

Each layer has independent fallback paths, ensuring continuity even during outages.

💳 Frontend Resilience (CITs / Card Capture)

1. Dual Writing (Primary Resilience Layer)

• Enables card data to be sent directly to payment processors if the Basis Theory Vault API experiences downtime.
• Our Elements are statically distributed via a global CDN with near-perfect uptime.
