Top 10 Best Database Encryption Software of 2026

CipherTrust Transparent Encryption (CTE) by Thales is a premier database encryption solution that secures sensitive data at rest across major databases like Oracle, SQL Server, MySQL, PostgreSQL, and DB2 without requiring application code changes or data migration. It delivers field-level and table-level encryption, granular access controls, and centralized key management to ensure compliance with standards such as PCI-DSS, HIPAA, and GDPR. CTE minimizes performance impact through efficient proxy or agent-based architectures while supporting multi-tenancy and dynamic data masking.

Protegrity Data Protection is an enterprise-grade data security platform specializing in database encryption, tokenization, and dynamic masking to safeguard sensitive data across heterogeneous environments. It supports a wide range of databases including Oracle, SQL Server, PostgreSQL, MongoDB, and big data platforms, enabling protection at rest, in transit, and in use without significant application changes via its transparent proxy architecture. The solution ensures compliance with GDPR, HIPAA, PCI-DSS, and other regulations through granular controls and audit capabilities.

IBM Security Guardium Data Encryption is an enterprise-grade solution designed to protect sensitive data at rest across databases, files, and big data environments. It offers transparent encryption without requiring application code changes, supporting major databases like Oracle, SQL Server, DB2, and Hadoop. Key features include centralized key management, compliance reporting for standards like PCI DSS and GDPR, and integration with the broader IBM Guardium security platform for unified data protection.

Voltage SecureData, now part of OpenText (formerly Micro Focus), is a data-centric encryption platform specializing in format-preserving encryption (FPE) for databases and applications. It protects sensitive data such as PII and payment information by encrypting it at rest and in transit while preserving data format, length, and query performance. The solution supports tokenization, secure search, and multi-tenant environments, making it ideal for compliance-heavy industries like finance and healthcare.

Symantec Database Encryption, now offered by Broadcom, is an enterprise-grade solution designed to protect sensitive data at rest across a wide range of database platforms including Oracle, Microsoft SQL Server, IBM DB2, and MySQL. It provides transparent encryption that operates without requiring application changes, ensuring minimal performance impact while maintaining data availability. The software includes centralized key management, policy-based encryption, and integration with hardware security modules (HSMs) for enhanced security and compliance with standards like PCI-DSS, HIPAA, and GDPR.

Oracle Transparent Data Encryption (TDE) is a native feature of Oracle Database Enterprise Edition that encrypts sensitive data at rest, including entire tablespaces, specific columns, or tables, without requiring modifications to applications or SQL queries. It operates transparently by encrypting data before writing to disk and decrypting it on-the-fly for authorized access, minimizing performance overhead. TDE supports advanced security options like Hardware Security Module (HSM) integration, auto-login keystores, and compliance with standards such as PCI-DSS and GDPR.

SQL Server Transparent Data Encryption (TDE) is a native feature in Microsoft SQL Server Enterprise Edition that encrypts entire databases, log files, and TempDB at rest using AES encryption algorithms. It operates transparently, meaning applications and queries require no modifications as encryption/decryption happens automatically at the I/O level. TDE supports key management via certificates, service master keys, or external key managers like Azure Key Vault or HSMs, ensuring compliance with standards like GDPR and HIPAA.

MySQL Enterprise Transparent Data Encryption (TDE) is a built-in feature of MySQL Enterprise Edition that provides at-rest encryption for InnoDB tablespaces, including data files, redo logs, and undo logs, without requiring changes to applications or SQL queries. It operates transparently, automatically encrypting data as it is written to disk and decrypting it during reads using a master key managed externally. TDE helps meet compliance requirements like GDPR, HIPAA, and PCI-DSS by securing data at the storage layer.

Baffle Data Security is a database security platform that provides continuous data protection through field-level encryption, dynamic data masking, and tokenization without requiring changes to applications or underlying databases. It supports a wide range of cloud data warehouses like Snowflake, Redshift, BigQuery, and traditional databases such as PostgreSQL and Oracle. Baffle enables organizations to enforce granular access controls and comply with regulations like GDPR, HIPAA, and PCI-DSS while preserving query performance.

PK Protect by PKWARE is a data-centric security platform specializing in persistent encryption for databases, filesystems, and big data environments. It provides transparent, format-preserving encryption that protects sensitive data at rest without requiring application changes or impacting query performance. Supporting major databases like Oracle, SQL Server, DB2, and PostgreSQL, it ensures compliance with regulations such as GDPR, HIPAA, and PCI-DSS through centralized key management and granular access controls.
