Modernize beyond tokenization and perimeter security

Refined Question

Our current protections are a tokenization vault from one era and network perimeter controls from another. Both fight modern architectures — vaults add latency and a single point of failure, perimeters dissolve in the cloud. What does the modern replacement look like?

Why This Matters

Tokenization centralises risk in the vault and strips data of its utility — every search and analytic needs a detokenization round-trip. Perimeter models assume an inside and an outside that cloud and AI architectures no longer have. Both leave the actual data unprotected the moment their boundary is crossed.

Why CipherStash

CipherStash protects the values themselves. Searchable encryption keeps data useful without round-trips to a vault; per-value keys derived by ZeroKMS remove the central honeypot; identity-bound decryption enforces access wherever the data travels.

This allows:

• Tokenization vaults to be retired without losing searchability
• Protection to persist beyond any network or organisational boundary
• Latency and availability to stop depending on a central detokenization service
• A single model to cover applications, analytics, and AI consumers

Key Differentiators

• Searchable encryption — equality, range, and free-text queries over encrypted Postgres fields, with standard indexes
• Per-value keys via ZeroKMS — keys are derived on demand, never stored
• Application-layer encryption — data is protected before it reaches the database
• Identity-aware decryption — every decryption is bound to the identity behind the request
• No re-platforming — works over the Postgres you already run
