In their own words
AWS Key Management Service
AWS Key Management Service creates and controls cryptographic keys for data encryption and digital signatures. It centralizes key lifecycles and permissions, including separate control over administrators and key users. KMS supports symmetric encryption, asymmetric signing or encryption pairs, and HMAC generation and verification. The AWS Encryption SDK can use KMS as a key provider for local application encryption and decryption. Integrations include Amazon S3, EBS, RDS, DynamoDB, Lambda, and CloudTrail. With CloudTrail enabled, requests can record the user, time, API action, and key. AWS says hardware security modules validated to FIPS 140-3 Security Level 3 protect key material and operations, with plaintext keys kept only in volatile HSM memory. Multi-Region keys support cross-Region workflows; external key stores keep material in a customer-managed external manager. KMS scales with demand but has default key and request limits. The listed plan is $1 a month per KMS key, prorated hourly.
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.
