Column-level encryption for open-source databases without code changes
MyDiamo is a transparent column-level encryption solution for open-source databases including MySQL, MariaDB, PerconaDB, and PostgreSQL. Developed by Penta Security Systems since 2013, it operates at the engine level requiring no code modification, providing 256-bit encryption with access control and auditing for HIPAA and PCI-DSS compliance.
Encrypt specific database columns with 256-bit encryption rather than entire tables, minimizing performance overhead
Engine-level operation requires no application code modification for seamless integration
Encrypt only sensitive fields like SSNs or credit cards while leaving non-sensitive data accessible
Granular control over who can access encrypted data with role-based permissions per column
Track and monitor all access to encrypted columns for compliance reporting and security analysis
Works with MySQL, MariaDB, PerconaDB, and PostgreSQL on both Windows and Linux
Helps meet HIPAA, PCI-DSS, GDPR, and other regulatory requirements for data protection
Encrypt patient records and PHI in MySQL/MariaDB databases to meet HIPAA requirements without rewriting applications
Protect credit card numbers and financial data at the column level for PCI-DSS compliance
Encrypt personally identifiable information in European applications while keeping non-sensitive business data accessible
Measured 6.5% overhead by sysbench, significantly less than full-database encryption approaches
