rypt Rule: Adopt Only When Client Data Residency and Key Custody Are Contractual Requirements

rypt handles key custody in Google Cloud KMS and logs every operation to an append-only audit trail, which means the agency never touches key material and can hand auditors a log without building logging infrastructure. The four pricing tiers (Free at $0, Extra Wrapped at $3/month, Software at $10/month, and Hardware) scale with operation volume, so a single-client deployment rarely exceeds double-digit monthly vendor cost. The verdict positions rypt for agencies already doing custom application development or data security consulting, not for general-purpose SaaS resellers, because the value comes from embedding the REST call into client code the agency already owns.

• •The client operates in healthcare, fintech, or e-commerce and has a written requirement to encrypt specific data fields at rest (SSN, DOB, payment info) rather than whole-database encryption.
• •The client's expected monthly encrypt/decrypt volume sits between 10,000 and 100,000 operations, which maps to rypt's Free, Extra Wrapped ($3/month), or Software ($10/month) tiers without over-provisioning.
• •The agency already delivers custom application development or data security consulting, so adding a REST encryption call to an existing build is incremental work rather than a new service line.
• •The client's compliance auditor requires an append-only log of every key operation, which rypt produces natively and which the agency would otherwise have to build and maintain.
• •The agency is prepared to charge a retainer on top of rypt's per-key monthly fees rather than absorbing the vendor cost into a fixed-price project.
