QuintessenceLabs Trusted Security Foundation vs SAP Data Custodian Key Management Service

QuintessenceLabs Trusted Security Foundation (TSF) is a centralized manager for cryptographic keys and policies across the key lifecycle. It is offered as a virtual machine or hardware appliance; TSF 100 virtual appliances can run locally or on AWS, Azure, and GCP. Product materials describe policies for objects and users, plus replication across up to 16 nodes. The TSF range supports OASIS KMIP and has been tested with products from IBM, HP, Oracle, and NetApp. Listed capabilities cover one-time pad, symmetric and asymmetric ciphers, key derivation, random objects, certificates, and selected cryptographic operations. Administrators can use web HTTPS or command-line SSH interfaces. The product sheet states support for thousands of end-client systems, tens of millions of keys, and 8,000 key requests per minute per node. The maker says TSF 400 contains an Entrust nShield XC FIPS 140-3 Level 3 validated HSM as a root of trust. TSF is under evaluation for Common Criteria NDcPP compliance. The maker also states that its key management application is compliant with NIST SP 800-57 where applicable. Pricing is available on request, with configurations tailored to different needs.

SAP Data Custodian Key Management Service is a cloud service accessed through the web for managing cryptographic keys. It supports three listed key types: AES, RSA, and ECC. Automated key rotation changes keys according to the service’s rotation capability, while key audit logs provide records of key-related activity. The service supports external key control and also lists a combined external-and-other control option, giving organizations more than one way to handle control of keys. Its deployment model is cloud, and its platform is web. SAP sells the service on a paid basis. Pricing is available on request, and no free plan is listed. Organizations can use the service as a web-based cloud option when AES, RSA, or ECC management, rotation, control choices, and audit logging are requirements.
