User Guide – Privacera Encryption Gateway (PEG)

Privacera Encryption Gateway (PEG) enables secure, policy-driven encryption and decryption of sensitive data across hybrid and multicloud environments. It is tightly integrated with the Privacera Platform and works seamlessly with various data platforms including Databricks, StreamSets, Trino, Redshift, and more.

PEG provides advanced field-level encryption, format-preserving encryption (FPE), tokenization, masking, and hashing—ensuring both security and data usability. It supports vaultless tokenization and strong AES encryption (128-bit and 256-bit), making it ideal for securing personally identifiable information (PII), financial records, and other regulated data.

Key Features

  • Centralized Encryption Management
    Define, manage, and enforce encryption schemes and policies through a unified interface within Privacera.

  • Flexible Encryption Algorithms
    Support for Format-Preserving Encryption (FPE), AES (Standard/256-bit), tokenization, hashing (SHA-256/SHA-512), and masking.

  • Integrated Key Management
    Use Privacera Vault or connect to external KMS providers like AWS KMS and Azure Key Vault to securely manage keys.

  • Native Integration with Data Platforms
    Out-of-the-box connectors for Databricks, StreamSets, Trino, Snowflake, Redshift, and more—with native UDF support and automated certificate provisioning.

  • Policy-Driven Encryption Controls
    Apply fine-grained encryption policies using Privacera's policy engine, based on user roles, data classification, or context.

  • Secure REST API & CLI Support
    Perform encryption, decryption, and masking through secure REST endpoints and command-line utilities.

Benefits

  • Stronger Data Security
    Encrypt sensitive fields at the column level—across databases, files, and streaming data—to reduce the risk of breaches.

  • Regulatory Compliance
    Meet data privacy and security requirements for GDPR, HIPAA, PCI DSS, and other regulations with built-in auditability.

  • Operational Flexibility
    Deploy with or without a cloud vault, support for deterministic and non-deterministic encryption modes, and customizable scheme formats.

  • Data Usability with Privacy
    Use FPE and selective masking to protect sensitive data without disrupting downstream systems, analytics, or workflows.

  • High Performance
    Native UDFs and PEG's caching mechanism reduce API roundtrips and ensure minimal performance overhead for real-time encryption.
