OpenTDF vs Virtru Data Security Platform
Comparing the open-source foundation with the mission-ready platform
OpenTDF is an open-source project that includes the Trusted Data Format (TDF) specification and foundational software services for data-centric security solutions. It provides a starting point for developers building custom applications, including basic key management, access control, and data encryption.
The Virtru Data Security Platform builds on this foundation and offers additional proprietary capabilities required to deliver a mission-ready platform, including:
- Standards support for IC-TDF, ACP-240 Zero Trust Data Format (ZTDF), Intelligence Community metadata (IC-EDH, ISM, IC-ID), and NATO STANAG 5636, including classification markings, releasability controls, and dissemination restrictions that travel with protected data
- Ready-to-deploy policy enforcement across collaboration applications, data analytics pipelines, and agentic AI workflows
- Automated tagging with native support for reading and writing STANAG and Intelligence Community handling metadata, along with support for metadata generated by third-party tagging systems like Fortra and JanusNet
- Universal identity integration with any OIDC/OAuth2 provider
- Enterprise key management with native HSM support ensuring full key sovereignty within FIPS 140-2/3 validated hardware
- Advanced cryptography with FIPS-validated options and support for FIPS-203/204 Post-Quantum Cryptography
Feature Comparison for OpenTDF and Virtru Solutions
The chart below compares OpenTDF and the Virtru Data Security Platform, highlighting key differences in scope, capabilities, and use cases.
| Feature Category | OpenTDF | Virtru |
|---|---|---|
| Administration & Management | ||
| System Configuration | Headless / Config-as-Code Configuration requires editing YAML/JSON files, Helm charts, or making direct API calls. No visual interface. | Unified Web Console Comprehensive graphical interface for managing system settings, platform configurations, and service integrations. |
| Policy Management | CLI / API only | Visual Policy Builder No-code, drag-and-drop web UI for defining attributes, creating rules, and managing access logic. Import / Export Policy Support for import and export of atomic policy bundles with the ability to run the platform backed by a read-only policy backbone. |
| Standards & Interoperability | ||
| TDF Formats Supported | Base TDF Only Reference implementation of the standard JSON-based Trusted Data Format. | Multi-Format Support Support for Base TDF, IC-TDF (US Intelligence Community), ACP 240 ZTDF, and proprietary Binary TDF for high-volume data streaming and IoT applications. |
| Data Tag Extraction and Processing | None No native tagging service; developers must build their own solution to extract attributes from raw data and normalize across multiple data tagging regimes. | Extensible Tagging Service Fully supported Tagging Service with out-of-the-box support for CCEB STANAGs, US Intelligence Community Handling Metadata , and Fortra tags. Extensible via API. |
| Data Integrity | Hooks Only API stubs for assertions, but no direct support for Organizational PKI. Default implementation requires data entitlement to verify metadata signatures. | Signed Assertions Native integration with Organizational PKI to cryptographically sign metadata for non-repudiation and provenance. |
| Integrations & Ecosystem | ||
| Policy Enforcement Points (PEPs) | Build Your Own SDKs provided; you must write the code to integrate policy enforcement into applications. | Full Collaboration and Data Analytics Suites Ready-to-deploy PEPs for Microsoft Outlook, Exchange, SharePoint, SMTP Gateway, Windows Desktops, Secure Share Enclave; S3 Object Storage, Apache Trino, and Apache NiFi. Proprietary SDKs for advanced features like data tagging. |
| Centralized Configuration Service | N/A | Consolidated Service Management Allowing for streamlined administration of deployed PEP solutions |
| Search Capabilities | N/A | Encrypted Search Proprietary technology enabling search over encrypted data without decrypting the payload. |
| Authorization Extensibility | N/A | Integration With Authorization Systems Allows extension of the base authorization system |
| Identity Provider Support | Limited Reference implementation tightly coupled with Keycloak. | Universal Identity Support Agnostic integration with any OIDC/OAuth2 provider, including Ping Federate, Okta, Azure AD, and Keycloak. |
| Key Management | ||
| HSM Support | Software Only Basic Key Access Service (KAS) implementation without hardware bindings. | Enterprise HSM & Cloud KMS Native support for Thales Luna, Entrust nShield, AWS KMS, and Google Cloud KMS. |
| Cryptography | Standard Base AES encryption for data Encryption with support for RSA or ECC-based key encryption . | Advanced & Future-Proof FIPS-validated options and support for FIPS-203/204 Post-Quantum Cryptography. |
| Enterprise Security | ||
| Audit Logs | No | Yes |
| SSO with SAML 2.0 support | No | Yes |
| Compliance (HIPAA, SOC-2 Type 2, FedRAMP Moderate, PCI-DSS) | No | Yes |
| Deployment | ||
| Self-Hosted / DIY You define the architecture, scaling, and reliability engineering. | SaaS / Hybrid / Private Managed SaaS or customer-hosted private cloud options with SLA guarantees. |
|
| Support | ||
| Open source community-based support (no SLA) | Help and support from the creators and maintainers of OpenTDF. | |
