Value proposition
Enables developers to take full control of their payments stack through powerful encryption infrastructure - tokenize credit cards, optimize payment margins, achieve PCI compliance (reducing scope by up to 95%), avoid payment processor lock-in, and spin up card issuing programs. Customers can encrypt data at collection and maintain it encrypted throughout its lifecycle while still processing it, without storing plaintext or managing encryption keys.

Unique value
Evervault's dual-custody encryption model fundamentally differs from traditional tokenization - they never store customer data (customers store encrypted data themselves), while Evervault manages the encryption keys. This architecture requires both the client AND Evervault to be compromised for a successful data breach, eliminating single points of failure. Their zero-latency tokenization enables creating encrypted tokens without network requests (microseconds vs seconds), and their modular platform unbundles payment security from processors, giving developers flexibility to route payments to any processor while maintaining control.
Target customer
Developers and engineering teams at companies ranging from early-stage startups to large financial institutions who need to collect, process, and secure sensitive payment data while maintaining compliance (PCI DSS, HIPAA, GDPR)
Industries served
["Payments & FinTech","Banking & Financial Services","E-commerce & Retail","Healthcare & HealthTech","SaaS & Technology","Card Issuing","Payment Orchestration","Travel & Hospitality","Digital Insurance"]
Technology advantage
Built on the proprietary Evervault Encryption Engine (E3) powered by AWS Nitro Enclaves with Shamir's Secret Sharing for key management - splitting keys into three shares with quorum of three. Combines Elliptic Curve Cryptography (ECC) with AES-256-GCM for performance-optimized encryption (offers 5x faster r1 curve vs k1 curve). Their developer-first approach provides simple SDK integration across languages, infinitely customizable UI components with CSS-in-JS, auto-scaling to millions of transactions, and automatic key rotation/provisioning. Enables processing encrypted data in secure enclaves via Docker containers with built-in TLS attestation. Achieves PCI DSS compliance reduction to SAQ A level (95% fewer controls), HIPAA compliance with BAAs, and supports GDPR/CCPA requirements.
How they differentiate
Evervault's dual-custody encryption model fundamentally differs from traditional tokenization - they never store customer data (customers store encrypted data themselves), while Evervault manages encryption keys. This eliminates single points of failure and vendor lock-in. Their zero-latency tokenization enables encryption in microseconds vs seconds, and their modular platform unbundles payment security from processors, giving developers flexibility to route payments to any processor.
