VESSOT (Vault Encrypted Single Source Of Truth) is a SaaS platform that gives businesses one encrypted, centralized vault for storing and syncing sensitive data pulled from disparate systems such as CRM, analytics, e-commerce, HR, and finance tools. Data is protected with zero-knowledge, AES-256-GCM encryption, meaning only the account owner and their authorized users can ever decrypt stored information -- VESSOT itself cannot read it. The platform is API-first: developers integrate via a RESTful API or a PHP Composer library exposing simple store, show, update, and destroy operations, with ready-made extensions available for WordPress and Magento 2. VESSOT targets teams building mission-critical applications that need a portable, encrypted single source of truth for customer, financial, or operational data, with GDPR- and HIPAA-oriented security controls and single sign-on support.

PHP Composer Library — A standalone PHP library exposing store, show, update, and destroy methods for custom application integrations.
WordPress & Magento 2 Integrations — Pre-built, platform-native integrations automate the encrypted data workflow for WordPress and Magento 2 sites.

Pros & Cons
Pros
Zero-knowledge, AES-256-GCM encryption means VESSOT itself cannot access stored data

Simple, well-documented CRUD-style API and PHP Composer library make integration straightforward
Ready-made WordPress and Magento 2 integrations reduce setup work for common platforms
30-day free trial lets teams evaluate the platform before paying
Cons
No published tiered/enterprise plans -- pricing is pay-per-use only, which may be harder to budget for at scale
Integration currently centers on a PHP library plus WordPress/Magento plugins, which may limit fit for teams outside the PHP ecosystem
Public evidence of company background (founding date, team size, headquarters) is limited
Support appears limited to email, with no published live chat or phone option
