Encryption Key Management Software Resources

In encryption key management tools, we've been exploring how infrastructure and security teams manage keys and secrets across AWS, GCP, Azure, and on-prem environments simultaneously. The challenge that keeps surfacing is maintaining a single control plane for policy enforcement, automated rotation, and access governance without being locked into one provider's native tooling.

Here are five platforms worth considering for multi-cloud infrastructure automation and centralized key control:

1. Akeyless Identity Security Platform — Built cloud-native from the ground up, it unifies secrets management, PKI, certificate lifecycle, and PAM across hybrid and multi-cloud environments through a single control plane.
2. Doppler Secrets Management Platform — It centralizes secrets and environment config across cloud environments and syncs directly with Kubernetes, Terraform, and major CI/CD platforms.
3. Azure Key Vault — It offers centralized secret, certificate, and key management with deep integration into Azure DevOps, ARM templates, and managed identities
4. AWS Key Management Service (KMS) — It provides deeply integrated, IAM-governed encryption key management with cross-region replication and native hooks across S3, RDS, Lambda, and the broader AWS service catalog.
5. IBM Vault (formerly HashiCorp Vault) — A battle-tested platform built specifically for the multi-cloud, multi-system problem. Dynamic secrets, policy-as-code, and automatic lease-based rotation work across AWS, Azure, GCP, and on-prem without requiring infrastructure standardization.

For those managing key and secrets infrastructure across multiple cloud providers: which approach has actually held up at scale? Was it a cloud-native abstraction layer, leaning into your primary provider's native tooling, or going fully platform-agnostic? And did centralized policy enforcement or automated rotation end up being the bigger unlock?

Are there perhaps some online courses or instructional videos that will help me get more out of this platform? Since I only use one or two features in Egnyte, I would like to know if there were any other features that I have yet to discover on Egnyte that would be a benefit me and my job?
