Kubernetes security doesn't have to slow you down. We break down the top platforms for secrets management, CI/CD pipeline scanning, and managed infrastructure — HashiCorp Vault, GitLab, and Amazon EKS — so you can ship fast without compromising on security.
If you're running containers in production, you already know the tension: move fast, but don't get pwned. A 2024 Red Hat survey found that 90% of organizations encountered at least one Kubernetes security incident in the past year.1 That's not a stat you can ignore.
The good news? The DevSecOps movement and "shift left" philosophy — catching vulnerabilities before they reach production — means security tooling has caught up. You don't have to choose between speed and safety. You just need the right platforms.
Here are three tools that cover the most critical Kubernetes security surfaces: secrets, pipelines, and infrastructure.
| Pick | Best For | Key Strength |
|---|---|---|
| HashiCorp Vault | Secrets management | Dynamic credentials, automated rotation, granular access controls |
| GitLab | CI/CD pipeline security | Built-in container registry + security scanning in your pipeline |
| Amazon EKS | Managed K8s infrastructure | Deep AWS security service integration at scale |
If you're still storing API keys, database passwords, or TLS certificates in plaintext ConfigMaps, stop. HashiCorp Vault is the industry standard for Kubernetes secrets management, and for good reason.
Vault transforms how you handle secrets by generating dynamic credentials on demand — so there's no static secret to leak. It also handles automated rotation and enforces granular access controls at the application level.2
> Bottom line: If your team deals with any sensitive credentials (and every K8s team does), Vault is the first thing you should add to your stack.
Best for: Teams that need enterprise-grade secrets management with dynamic, short-lived credentials.
Security that happens after deployment is too late. GitLab brings security scanning directly into your CI/CD pipeline, so vulnerabilities are caught the moment code is committed — not when it's already running in production.
GitLab provides built-in CI/CD pipelines, a container registry, and integrated security scanning that checks your container images for known vulnerabilities before they ever get deployed.3 This is the "shift left" approach in practice: find the problem before it becomes an incident.
Best for: Teams already using GitLab who want to consolidate their toolchain and add security without bolting on a separate scanner.
Sometimes the most secure option is letting someone else manage the control plane. Amazon Elastic Kubernetes Service (EKS) gives you a managed K8s environment with deep integration into AWS's security ecosystem — IAM roles for service accounts, VPC networking controls, and AWS PrivateLink for secure API access.
EKS handles control plane patching, uptime monitoring, and certificate rotation, so your team can focus on workloads instead of cluster administration.
Best for: Teams already on AWS who want a managed, enterprise-grade K8s experience with minimal operational overhead.
| Dimension | Vault | GitLab | EKS |
|---|---|---|---|
| Primary function | Secrets management | CI/CD + scanning | Managed K8s |
| Deployment model | Self-hosted or cloud | SaaS or self-hosted | AWS-managed |
| Best for | Credential hygiene | Pipeline security | Infrastructure scale |
Your Kubernetes security strategy isn't one tool — it's a stack. Start with Vault for secrets, layer in GitLab for pipeline scanning, and run it all on EKS if you're in AWS. Each covers a different attack surface, and together they give you a solid foundation.
