Secure fragmented multi-cloud and SaaS architectures

Refined Question

Our data now lives across multiple clouds, managed databases, and dozens of SaaS tools, each with its own access model. How do we apply one coherent protection standard across an architecture we don't fully control?

Why This Matters

Perimeter security assumes there is a perimeter. In a multi-cloud, SaaS-heavy stack, the "perimeter" is the union of every vendor's security posture — and your exposure is set by the weakest of them. Re-securing each boundary separately doesn't scale and never converges.

Why CipherStash

CipherStash makes the data self-protecting. Values encrypted at the application layer remain ciphertext wherever they travel — across clouds, through integrations, into vendor systems — and can only be decrypted by an authorised identity, wherever that decryption happens.

This allows:

• One protection model to hold across every cloud and vendor boundary
• SaaS and integration breaches to expose ciphertext, not customer data
• Security posture to stop depending on each vendor's weakest control
• New services to be added without redrawing the security architecture

Key Differentiators

• Application-layer encryption — data is protected before it reaches the database
• Per-value keys via ZeroKMS — keys are derived on demand, never stored
• Identity-aware decryption — every decryption is bound to the identity behind the request
• No re-platforming — works over the Postgres you already run
• Cryptographic auditability — a verifiable record of who decrypted what, and when
