TL;DR: Akeyless compares AWS Secrets Manager and HashiCorp Vault as two different answers to NHI secrets governance: one is a low-ops AWS service billed at $0.40 per secret each month, while the other is a cloud-agnostic platform that issues dynamic, short-lived credentials but must be operated by the customer. The real decision is whether your programme needs native AWS simplicity or cross-cloud lifecycle control.
Editorial analysis by NHI Mgmt Group, based on content published by Akeyless: “AWS Secrets Manager vs HashiCorp Vault: The Cost Math Nobody Runs”.
By the numbers:
- HashiCorp Vault's break-even with AWS Secrets Manager typically lands between roughly 3,000 and 8,000 secrets.
Key questions
Q: What breaks when teams store reusable secrets outside a governed lifecycle?
A: What breaks is not only confidentiality but also revocation, auditability, and ownership.
Q: Should organisations prioritise dynamic secrets over managed storage?
A: Prioritise dynamic secrets when credential lifetime is the main risk and the workload can authenticate without a permanent shared secret.
Q: What are the signs that a secrets platform is becoming too expensive to run?
A: The warning signs are rising engineer time, repeated unseal or upgrade work, expanding monitoring effort, and growing exception handling across clouds or environments.
Practitioner guidance
- Define the credential lifecycle by workload type Separate static application secrets from dynamically issued workload credentials, because each requires a different ownership model, rotation policy, and audit trail.
- Measure the real cost of operating Vault Include engineer time, infrastructure, monitoring, and unseal operations when comparing Vault against managed storage, not just license cost.
- Map bootstrap trust for every non-human identity Document how each workload authenticates before it can retrieve or mint a secret, especially where AWS IAM, Kubernetes service accounts, or certificates are involved.
Bottom line: AWS Secrets Manager and Vault solve the same problem through different governance models, not just different price points.

Static secret sprawl is a governance problem, not just a storage problem: The comparison only looks like a billing debate until teams account for how many secrets sit outside governed systems. When credentials live in files, pipelines, or ad hoc stores, the real cost is fragmented lifecycle control and unclear ownership. The practical conclusion is that storage location matters less than whether the credential estate can be governed end to end.
A few things that frame the scale:
- 96% of organisations store secrets outside of secrets managers in vulnerable locations including code, config files, and CI/CD tools, according to the Ultimate Guide to NHIs.
A question worth separating out:
Q: How should security teams replace shared secrets for workloads that span multiple clouds?
A: Use federated workload identity so the workload proves who it is with a signed token or attestation instead of a shared static secret. Then scope the resulting credential tightly to the request and make the trust relationship revocable when the workload, supplier, or environment changes.
