Choosing Vaulted Tokenization: The Advantages Over Vaultless
Blog post from Basis Theory
Vaulted and vaultless tokenization take different approaches to protecting payment and personally identifiable information in e-commerce. Vaulted tokenization stores sensitive data in a centralized secure vault and gives merchants randomly generated tokens that cannot be decrypted or reverse-engineered, allowing transactions to be processed without exposing underlying data to merchant systems. Vaultless tokenization instead tokenizes data locally through an encryption-based process that recipients can decrypt, enabling distributed architectures, potentially faster processing, and broad scalability but introducing risks if encryption keys or methods are compromised. The comparison argues that vaulted tokenization offers stronger security, reduces PCI-DSS compliance scope and associated costs, preserves merchant control over payment data, and provides a single integration point for multiple payment processors, while acknowledging that vault infrastructure must be managed to avoid performance or availability issues.
