Your data. Only yours.

PaySentry uses AES-256-GCM encryption with per-tenant keys derived through HKDF. Zero-knowledge means exactly that -- even PaySentry cannot access your encrypted data. In an industry where a competitor has already been breached, this isn't a feature. It's a requirement.

Architecture

How we protect your data.

AES-256-GCM

Military-grade encryption standard. The same encryption used by governments and financial institutions worldwide.

Per-tenant encryption keys

Your data is encrypted with keys unique to your organisation. No shared keys, no shared risk. Your data is fully isolated.

Zero-knowledge architecture

PaySentry staff cannot access your data. Not won't -- cannot. The architecture makes it technically impossible.

Encrypted at rest and in transit

Data is encrypted the moment it enters the platform and stays encrypted in storage. No plaintext, anywhere.

Privacy-preserving search

HMAC-SHA256 blind indexes allow the platform to search and match encrypted data without ever decrypting it. Compliance screening works on hashes, not raw data.

Trust is earned. Not assumed.

The umbrella compliance industry handles sensitive worker data -- payslips, tax codes, National Insurance numbers, personal details. A breach doesn't just cost money. It costs trust.

A competitor in this space has already suffered a data breach while displaying Cyber Essentials badges. Badges mean intentions. Architecture means protection.

PaySentry was built from day one with zero-knowledge encryption. It wasn't bolted on. It's how the platform works.

Security by design, not by promise.
