In their own words
Bloombase KeyCastle
Bloombase KeyCastle manages cryptographic keys and certificate authority certificates, including private signing keys, public verification keys, authentication keys, and data encryption keys. It supports key creation, import, protected storage, verification, validation, inquiry, and deletion. Bloombase says keys stored in KeyCastle cannot technically be retrieved in plain form; its specifications say capacity is limited by available system storage, not a preset key count. Listed algorithms include AES, RSA, SHA hashes, Camellia, SEED, ARIA, and post-quantum options such as CRYSTALS-Kyber and CRYSTALS-Dilithium. KeyCastle supports PKCS#11 hardware security modules, OASIS KMIP, and a listed FIPS 140-2 compliant Bloombase Cryptographic Module. It connects with key services from AWS, Google, IBM, Microsoft Azure, and Oracle. Certificate functions include X.509 and PKCS#12 import and export, validity checks, retrieval, and revocation checks. Administration includes web and command-line consoles, central configuration, SNMP, and syslog. Optional high availability supports active-active or active-standby operation; recovery options include configuration backup and restore and recovery quorums. Pricing is on request, and Bloombase says customers may request a 30-day evaluation kit.
Utimaco Enterprise Secure Key Manager
Utimaco Enterprise Secure Key Manager (ESKM) centralizes cryptographic key management across on-premises and cloud environments. It provides policy controls, centralized administration, and audit trails for key lifecycle management, alongside monitoring, recovery, scheduled backups, log rotation, and restore functions. Administrators can use a web GUI or command-line interface. ESKM supports OASIS KMIP, a RESTful API, and a native XML-based KMS protocol; it conforms to KMIP specifications 1.0 through 2.1 and supports client libraries including OpenKMIP and PyKMIP. The product page states capacity for more than 2 million keys, over 25,000 clients, and thousands of nodes per distributed cluster. Four models are available, including a Linux-based virtual appliance and hardware appliances. Physical L3 and L4 models include embedded HSMs identified as FIPS 140-2 Level 3 and Level 4; the virtual L1 is a hardened appliance with FIPS 140-2 Level 1 security. Listed key types include AES, 3-Key Triple DES, HMAC, RSA, and ECDSA. Pricing is on request.
