AWS Key Management Service vs CrystalKey 360

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.

CrystalKey 360 is an API-based control layer for managing cryptographic policy and automating key lifecycles across hybrid environments. It supports governance of ownership, approvals, and evidence, and automates key rotation through API integrations. Native data-protection capabilities include tokenization, MACing, data masking, code signing, database encryption, encryption, and decryption. Logging across supported environments is intended to improve visibility, accountability, and evidence collection. The product is designed to work alongside existing cryptographic infrastructure, with integrations listed for HSMs from Thales, Utimaco, Entrust, and Futurex, as well as AWS, Azure, GCP, other cloud platforms, and supported key stores. Identified use cases include cryptographic estate consolidation, shared trust infrastructure, payment-key management, and preparation for algorithm transitions and key migration. It supports AES, 3DES, RSA, EC, and HMAC keys, with external key control through BYOK. Platforms include API, Linux, self-hosted, web, and Windows.
