We follow the guidelines outlined in the next few sections as an architectural baseline.

Do One Thing Well

At a 5000-feet level, VMware Secrets Manager is a secure Key-Value store.

It can securely store arbitrary values that you, as an administrator, associate with keys. It does that, and it does that well.

Be Kubernetes-Native

VMware Secrets Manager is designed to run on Kubernetes and only on Kubernetes.

That helps us leverage Kubernetes concepts like Operators, Custom Resources, and Controllers to our advantage to simplify workflow and state management.

If you are looking for a solution that runs outside Kubernetes or as a standalone binary, then VMware Secrets Manager is not the Secrets Store you’re looking for.

Have a Minimal and Intuitive API

As an administrator, there is a limited set of API endpoints that you can interact with VMware Secrets Manager. This makes VMware Secrets Manager easy to manage.

In addition, a minimal set of APIs means a smaller attack surface, a smaller footprint, and a codebase that is easy to understand, test, audit, and develop; all good things.

Be Practically Secure

Corollary: Do not be annoyingly secure.

Provide a delightful user experience while taking security seriously.

VMware Secrets Manager is a secure solution, yet still delightful to operate.

You won’t have to jump over the hoops or wake up in the middle of the night to keep it up and running. Instead, VMware Secrets Manager will work seamlessly, as if it doesn’t exist at all.

Secure By Default

VMware Secrets Manager stores your sensitive data in memory. None of your secrets are stored as plain text on disk. Anything that VMware Secrets Manager saves to disk is encrypted.

Yes, that brings up resource limitations since you cannot store a gorilla holding a banana and the entire jungle in your store; however, a couple of gigabytes of RAM can store a lot of plain text secrets, so it’s good enough for most practical purposes.

More importantly, almost all modern instruction set architectures and operating systems implement memory protection. The primary purpose of memory protection is to prevent a process from accessing memory that has not been allocated to it. This prevents a bug or malware within a process from affecting other processes or the operating system itself.

Therefore, reading a variable’s value from a process’s memory is practically impossible unless you attach a debugger to it. And that makes keeping plain text secrets in memory (and nowhere else than memory) crucial.

For disaster recovery, VMware Secrets Manager (by default) backs up encrypted version of its state on the file system; however, the plain text secrets that VSecM Safe dispatches to workloads will always be stored in memory.

Resilient By Default

When an VMware Secrets Manager component crashes or when an VMware Secrets Manager component is evicted, the workloads can still function with the existing secrets they have without having to rely on the existence of an active secrets store.

When an VMware Secrets Manager component restarts, it seamlessly recovers its state from an encrypted backup without requiring manual intervention.


VMware Secrets Manager epitomizes robust security principles with a keen focus on simplicity and user-friendliness. Its architecture is rigorously aligned with Kubernetes-native principles, leveraging the platform’s features to ensure seamless operation and maintenance.

By concentrating on a minimalistic API, VMware Secrets Manager not only simplifies user interactions but also enhances security by reducing the attack surface. Its commitment to being practically secure—storing secrets in memory and encrypting any data on disk—demonstrates a balance between strong security measures and operational practicality.

Additionally, the system’s inherent resilience ensures that service continuity is maintained, even during component failures, without compromising on security.

These qualities make VMware Secrets Manager an ideal choice for administrators seeking a dependable, secure, and efficient way to manage secrets within Kubernetes environments.
