Best Secrets Management Software for Cloud

Use keys to protect the secrets, personal data, and sensitive information you store in the cloud. Create and delete keys, set up access policies, and perform rotation via the management console, CLI, or API. Yandex KMS implements symmetric and asymmetric cryptography. Use the REST or RPC API to encrypt and decrypt small amounts of data, such as secrets and local encryption keys, as well as to sign data using e-signature schemes. You manage access to encrypted data, and Yandex KMS ensures the reliability and physical security of keys. Hardware Security Modules (HSMs) are available. Encrypt small amounts of data using the SDK in Java or Go. To encrypt larger amounts of data, the service is integrated with popular encryption libraries, including the AWS Encryption SDK and Google Tink. Integration with Yandex Lockbox makes it possible to encrypt secrets with your own keys. Secrets and data can also be protected using encryption keys in Managed Service for Kubernetes.

Enhance data protection and compliance with Key Vault. Secure key management is essential to protect data in the cloud. Use Azure Key Vault to encrypt keys and small secrets like passwords that use keys stored in hardware security modules (HSMs). For more assurance, import or generate keys in HSMs, and Microsoft processes your keys in FIPS validated HSMs (hardware and firmware) - FIPS 140-2 Level 2 for vaults and FIPS 140-2 Level 3 for HSM pools. With Key Vault, Microsoft doesn’t see or extract your keys. Monitor and audit your key use with Azure logging—pipe logs into Azure HDInsight or your security information and event management (SIEM) solution for more analysis and threat detection.

Akeyless delivers identity security for an era shaped by automation and AI. The cloud-native platform secures machines, AI agents, and human access across hybrid, multi-cloud, and on-prem environments. It provides a practical path to secretless, identity-based access through secrets management, certificate lifecycle management and PKI, PAM, and unified governance. Akeyless is built on a cryptography foundation that combines encryption, key management, and Distributed Fragments Cryptography to keep sensitive material under customer control and protected from post-quantum threats. With integrations for cloud IAM, Kubernetes, CI/CD, and MCP-based AI agent workflows, teams can adopt and scale AI agents securely without expanding risk. Akeyless Jarvis™ delivers identity intelligence to surface risky access and strengthen oversight.

Stop struggling with scattered API keys, hacking together home-brewed configuration tools, and avoiding access controls. Give your team a single source of truth with Doppler. The best developers automate the pain away. Create references to frequently used secrets in Doppler. Then when they need to change, you only need to update them once. Your team's single source of truth. Organize your variables across projects and environments. The scary days of sharing secrets over Slack, email, git, zip files, are over. After adding a secret, your team and their apps have it instantly. Like git, the Doppler CLI smartly knows which secrets to fetch based on the project directory you are in. Gone are the futile days of trying to keep ENV files in sync! Practice least privilege with granular access controls. Reduce exposure when deploying with read-only service tokens. Contractor needs access to just development? Easy!
