Cy4Data Labs Cy4Secure

Cy4Secure is a data encryption product that applies field-level encryption, referred to by the company as Atomic-Level Encryption (ALE), to individual data fields within a database rather than encrypting an entire database with a single key. Each field is assigned its own encryption key, so that if a breach occurs, exposed data is limited to disconnected, individually encrypted fragments rather than a complete dataset. The product includes post-quantum cryptography intended to address "harvest-now-decrypt-later" threats where encrypted data collected today could be decrypted once quantum computing capabilities advance. Cy4Secure enforces access control at the data layer on a per-field, per-role basis, which the company states restricts what LLMs and AI agents can access to only authorized fields. The vendor states the product operates beneath the application layer, requiring no code changes and adding no measurable latency or database performance impact. Cy4Secure is positioned to support compliance requirements including SOC 2 Type II, HIPAA, PCI DSS, and CMMC 2.0, and uses 256-bit AES alongside post-quantum cryptography. The vendor states it integrates with cloud, on-premises, hybrid, and SaaS environments without requiring a rip-and-replace deployment, with most implementations reaching production within 30 days. An admin console provides visibility into key analysis, active and inactive keys, and growth metrics related to encryption key usage.
