Secure Your Container Workloads — From Image to Runtime
Container security addresses the complete container lifecycle — securing base images, scanning application images for vulnerabilities, enforcing runtime security policies in Kubernetes clusters, and providing the network policy and admission control that prevents container workloads from becoming a security liability.
What RLM Delivers on Container Security
Container adoption has outpaced container security maturity in most organizations. Misconfigured Kubernetes clusters, vulnerable container images, and overly permissive pod security policies are a rich attack surface. RLM advises on the container security architecture that protects containerized workloads without impeding developer velocity.
How We Approach Container Security
Every Container Security engagement starts with what you have today and ends with something running in production — with independent evaluation in between.
Container Security Posture Assessment
We assess your container security posture — image vulnerability density, Kubernetes configuration against CIS Benchmarks, RBAC policy quality, network policy coverage, and the runtime security gaps that represent your most significant container risk.
Container Security Platform Evaluation
We evaluate container security platforms — Aqua Security, Prisma Cloud, Sysdig, Twistlock/Prisma, Snyk Container, and Falco (open source) — against your Kubernetes environment, CI/CD integration requirements, and the runtime protection depth required.
Image Security Pipeline Design
We design the image security pipeline — base image hardening standards, vulnerability scanning in CI/CD, and the admission control policy (OPA/Gatekeeper, Kyverno) that prevents vulnerable or non-compliant images from being deployed.
Kubernetes Hardening & Network Policy
We assess and harden your Kubernetes configuration — pod security standards, RBAC least privilege, network policy implementation, and the secrets management approach — against the CIS Kubernetes Benchmark and your threat model.
Container Security Evaluation Criteria
What follows is the Container Security evaluation checklist we actually use — the criteria that predict outcomes rather than demo well.
Image Vulnerability Management
Container images inherit vulnerabilities from base images and installed packages. Evaluate the scanning coverage — OS packages, application libraries, and configuration files — and the remediation workflow that ensures vulnerable images are replaced promptly.
Kubernetes RBAC Complexity
Kubernetes RBAC policies accumulate over time and become overly permissive. Evaluate the RBAC audit approach and the least-privilege enforcement mechanism that prevents privilege escalation through Kubernetes permissions.
Runtime Threat Detection
Vulnerabilities in container images are pre-deployment concerns; runtime threats occur after deployment. Evaluate runtime security capabilities — syscall monitoring, behavioral baselines, and the response actions available when anomalous container behavior is detected.
Registry Security
Container images are often pulled from public registries that may include malicious images. Evaluate the image registry security controls — private registry enforcement, image signing and verification, and the policy that prevents untrusted image sources.
Secrets in Containers
Application secrets in environment variables or configuration files are a common container vulnerability. Evaluate the secrets management approach — Vault integration, Kubernetes secrets encryption, and the scanning that detects hardcoded secrets in images.
Network Policy Coverage
Default Kubernetes networking allows pod-to-pod communication without restriction. Evaluate the network policy implementation that enforces micro-segmentation between workloads and limits the blast radius of a compromised container.
"We had three overlapping security tools doing the same job. RLM helped us rationalize the stack, cut spend by 30%, and actually improve our detection coverage in the process."
Independent means we will tell you when the answer is to keep what you have.
Where This Matters Most
Sector-specific considerations we see repeatedly in security engagements.
A Sample of the Security Providers We Evaluate
RLM is vendor neutral. These are among 600+ providers in our evaluation set — inclusion here is not an endorsement, and we are paid by the provider you choose, not by any provider in particular. How that works →
