Skyflow is an API-first data privacy vault that isolates and protects sensitive data using tokenization and polymorphic encryption, enabling operations on encrypted data without decryption. It is designed for regulated industries such as fintech, healthcare, and enterprise SaaS, where compliance with GDPR, HIPAA, PCI DSS, and CCPA is critical. The platform provides a zero-trust architecture with fine-grained access controls at column and row levels, supporting both structured and unstructured data.

Skyflow counts GoodRx and IBM among its customers and has raised approximately $100 million in disclosed equity financing, processing over 2 billion API calls per quarter. In December 2024, Skyflow launched its 'Agentic AI Security and Privacy Layer,' and in mid-2025 it announced an 'MCP Data Protection Layer' for AI-agent workflows, extending protection to Model Context Protocol connections. The platform supports vaultless tokenization, format-preserving encryption, synthetic data generation, and auto-scaling, with native integrations to Snowflake, BigQuery, Databricks, and Redshift.

Skyflow's AI Gateway provides two-way data rehydration: it detects PII in prompts, de-identifies data before sending to LLMs, and rehydrates responses with original sensitive data only when access controls permit. This prevents sensitive information from being exposed to AI model providers. The platform also redacts and masks LLM prompts, supports policy-based masking that preserves context, and offers REST APIs for protection workflows.

Competitors include Protegrity, Protecto AI, Very Good Security, and Ubiq Security. While Skyflow offers end-to-end data protection and supports data residency requirements, it has no public pricing tiers, no free trial, and all calls to action route to sales contact forms. The platform is lightweight and quick to deploy, but its sales-led pricing model can be a barrier for smaller teams or those needing immediate cost transparency.

How it works

  1. Polymorphic encryption

    Allows queries, analytics, and AI inference on encrypted data without decryption, using patented polymorphic encryption.

  2. Two-way data rehydration

    De-identifies PII in prompts before sending to LLMs, then rehydrates responses with original data only when access controls permit.

  3. MCP data protection

    Secures data flows between AI agents and Model Context Protocol connections, announced in mid-2025.

  4. Vaultless tokenization

    Supports tokenization without a centralized vault, reducing infrastructure complexity while maintaining security.

  5. Format-preserving encryption

    Encrypts data while preserving its original format, enabling use in existing applications without schema changes.

  6. Policy-based masking

    Applies context-preserving masking policies to redact sensitive data in LLM prompts and responses.

  7. Auto-scaling

    Automatically scales to handle bulk data processing and high-volume API calls, processing over 2 billion calls per quarter.

Strengths and trade-offs

Strengths

  • Skyflow has raised approximately $100 million in disclosed equity financing, indicating strong investor confidence and financial stability.
  • The platform processes over 2 billion API calls per quarter, demonstrating its ability to handle high-volume, production workloads.
  • Skyflow counts GoodRx and IBM as customers, validating its use in regulated industries like healthcare and enterprise SaaS.

Getting started with Data Privacy Vault

  1. Sign up for Skyflow

    Navigate to the Skyflow website and fill out the sales contact form to initiate the sign-up process. A sales representative will reach out to discuss your use case, compliance requirements, and deployment options before granting access to the platform.

  2. Connect your data source

    Use Skyflow's REST API to connect your database or data warehouse, such as Snowflake or BigQuery. Provide connection credentials and specify the tables or fields containing sensitive data to be protected by the vault.

  3. Configure protection policies

    Define fine-grained access controls at the column and row levels using Skyflow's policy engine. Set rules for tokenization, encryption, and masking based on user roles and compliance requirements like GDPR or HIPAA.

  4. Tokenize sensitive data

    Call the Skyflow API to tokenize sensitive fields, such as credit card numbers or personal identifiers, using vaultless tokenization or format-preserving encryption. Verify that the tokenized data retains its format for use in existing applications.

  5. Deploy AI data protection

    Enable the AI Gateway to de-identify PII in prompts before sending them to LLMs. Configure two-way data rehydration to restore original sensitive data in responses only when access controls permit, ensuring compliance during AI workflows.
