Best Key Management System (KMS) Tools

Identity-Centric Security Protecting People, Devices, and Data in the AI Era

Fortanix is a data-first security company and a pioneer in Confidential Computing. We help enterprises discover, assess, and remediate data exposure risks across hybrid multicloud environments to maintain the privacy and compliance of their most sensitive and regulated data, wherever it may be.

For over 40 years, Futurex has been a trusted provider of hardened, enterprise-class data security solutions.

HashiCorp Vault is the industry standard for secrets management, providing a centralized system for storing and controlling access to tokens, passwords, certificates, and encryption keys. It enables Infrastructure as Code (IaC) security by allowing developers to pull secrets dynamically rather than hardcoding them in configuration files. Vault complements cloud-native security by offering a unified workflow across hybrid and multi-cloud environments, often replacing fragmented, cloud-specific key management services.

HashiCorp Vault is a secrets and cryptographic key management system used to store, distribute, rotate, and control access to encryption keys, certificates, tokens, and other sensitive material. In the Encryption & Key Management scope, Vault’s key management secrets engine centralizes lifecycle control while still interfacing with external KMS providers, and its encryption-as-a-service functions let applications encrypt data without exposing keys. It is typically chosen by teams operating mixed cloud and on-prem environments that need policy-controlled key handling, auditability, and integration with existing identity systems. Enterprise features are available through Vault Enterprise and HCP Vault Dedicated.

Together, we provide innovative platforms designed to reduce the complexity and risks of managing and protecting more applications, data, and identities than any other company can.

Protegrity provides encryption and key management for protecting sensitive data across databases, cloud services, and SaaS environments. In this category, its key-management controls focus on centralized lifecycle administration for master keys, repository keys, data store keys, signing keys, and data element keys, with support for external key custody through AWS KMS and Azure Key Vault. It is best suited for enterprises that need data-centric encryption controls tied to compliance and operational governance rather than a standalone hardware security module. The broader platform also includes adjacent data protection functions, but those are outside this profile.

Thales SafeNet is an enterprise MFA and access management platform combining authentication, SSO, and policy enforcement across on-premises, cloud, and virtual environments. The portfolio includes hardware tokens (eToken, smart cards, FIDO2 security keys), software authenticators, and the cloud-based SafeNet Trusted Access service. SafeNet serves large organizations requiring high-assurance authentication across distributed infrastructure, with particular strength in government and regulated sectors through FIPS 140-2 and Common Criteria certifications.

Vormetric, now part of Thales, is a data-at-rest encryption and key management product centered on the Data Security Manager (DSM) for centralized policy and key administration. It is used to protect files, databases, logs, and selected big-data workloads across physical, virtual, and cloud environments. In this category, it is best suited for enterprises that need centralized cryptographic control, auditability, and separation of duties for sensitive data protection. Adjacent capabilities historically included tokenization and access control, but the core buyer focus is encryption and key lifecycle management.
