Utimaco Enterprise Secure Key Manager (ESKM) centralizes cryptographic key management across on-premises and cloud environments. Policy controls, centralized administration, and audit trails support key lifecycle management. ESKM is offered in four models, including Linux-based hardware appliances and a virtual appliance. Physical L3 and L4 models have embedded HSMs identified as FIPS 140-2 Level 3 and Level 4; the virtual L1 appliance is described as security-hardened with FIPS 140-2 Level 1 security. The product page states capacity for more than 2 million keys, over 25,000 clients, and thousands of nodes in a distributed cluster. Interfaces include OASIS KMIP, a RESTful API, and a native XML-based KMS protocol, with conformance to KMIP specifications 1.0 through 2.1. Listed key types include AES, 3-Key Triple DES, HMAC, RSA, and ECDSA, as well as keys created with NIST- and BSI-recommended post-quantum algorithms. Operations include monitoring, recovery, scheduled backups, log rotation, and restore functions through a web GUI or command-line interface. Pricing is on request.
