Aikido Container Image Scanning
Teams shipping containers at scale across multiple registries need Aikido Container Image Scanning because its reachability analysis cuts false positives by actually determining which CVEs can execute in your environment, not just flagging every known vulnerability. The tool scans Kubernetes workloads directly and integrates with 12 major registries including ECR, GCR, and Artifactory, with AutoFix generating pull requests to patch real risks automatically. Skip this if your organization runs fewer than 50 container images monthly or needs runtime threat detection alongside build-time scanning; Aikido stops at the image layer and doesn't monitor what happens after deployment.
Teams running microservices on Kubernetes who need runtime exploit detection without vendor lock-in will find Security-Guard valuable; it's free and open source, so you can audit the detection logic yourself and avoid subscription creep as you scale. The 67 GitHub stars and active community contributions show it's actually maintained, unlike many abandoned security projects. Skip this if you need integration with your existing SIEM or want a vendor to guarantee SLAs on detection accuracy; Security-Guard is a detection tool, not a managed security service.
