How does Trivy compare to Amazon Inspector for container scanning?

Trivy is free, open-source (Apache 2.0), and scans container images, directories, Git repositories, IaC files (Terraform, CloudFormation), and SBOMs for vulnerabilities and misconfigurations. Inspector scans container images in ECR and EC2 instances continuously within AWS. Trivy integrates into any CI/CD pipeline on any cloud; Inspector is AWS-only. For multi-cloud or non-ECR registries, Trivy is the standard choice for container vulnerability scanning.

What is Snyk and why do development teams prefer it for container security?

Snyk scans container images directly from IDEs (VS Code, IntelliJ), CLI, and CI/CD pipelines, providing vulnerability results with suggested base image upgrades and contextual fix advice during development rather than post-deployment. Inspector scans images after push to ECR. Snyk's developer-first approach shifts security left into the development workflow, reducing the time to fix vulnerabilities. For DevSecOps programs where developers own remediation, Snyk's UX and fix guidance are superior.

When should I choose Sysdig or Aqua over Amazon Inspector for container security?

Choose Sysdig or Aqua when you need runtime security beyond static scanning: behavioral anomaly detection, syscall monitoring, Kubernetes admission control, network policy enforcement, and incident response for containers in production. Inspector focuses on vulnerability detection pre-runtime. Sysdig's Falco-based runtime detection catches zero-day threats that static scanning misses. Aqua provides a full platform from image build through production runtime protection.
