Grype logo

Grype

Fast, comprehensive vulnerability scanner for containers and filesystems

Active developmentPermissive licenseFast to deployGo

Why teams choose it

  • Scans Docker, OCI, and Singularity images directly
  • Detects vulnerabilities in major Linux distros and popular language package managers
  • Supports SBOM input (Syft, SPDX, CycloneDX) for faster analysis

Watch for

Limited to macOS and Linux binaries

Migration highlight

CI pipeline image validation

Automatically fail builds when newly introduced CVEs are detected in container images.

Dagda

Comprehensive Docker image security scanning and runtime monitoring

Permissive licenseFast to deployIntegration-friendlyPython

Why teams choose it

  • Static vulnerability scanning using CVE, BID, RHSA, RHBA databases
  • Malware detection via ClamAV integration
  • Runtime anomaly detection with Falco

Watch for

Requires a separate MongoDB instance

Migration highlight

CI/CD pipeline image validation

Automatically reject Docker images containing known CVEs or malware before deployment.

Dockle logo

Dockle

Secure Docker images with CIS‑compliant linting made simple

Permissive licenseFast to deployAI-powered workflowsGo

Why teams choose it

  • CIS Benchmark compliance checks for Docker images
  • Zero‑runtime dependencies; single binary execution
  • CI/CD friendly with JSON output and exit‑code control

Watch for

Only scans built images, not Dockerfile syntax

Migration highlight

CI pipeline image validation

Fail builds automatically when Dockle detects critical security violations.

Kubescape

Unified Kubernetes security from development to runtime

Active developmentPermissive licenseIntegration-friendlyGo

Why teams choose it

  • Multi‑framework misconfiguration scanning (NSA‑CISA, MITRE ATT&CK, CIS)
  • In‑cluster operator with continuous scanning, image vulnerability, runtime analysis, and network policy generation
  • CLI and GitHub Action for fast, on‑demand assessments

Watch for

Requires cluster access for in‑cluster operator

Migration highlight

Pre‑deployment compliance scan

Detects misconfigurations in Helm charts and YAML before they reach production, ensuring alignment with NSA‑CISA and CIS benchmarks.

Transparent vulnerability scanning for container images using static analysis

Active developmentPermissive licenseFast to deployGo

Why teams choose it

  • Static analysis of OCI and Docker images
  • API-driven image indexing and vulnerability matching
  • Transparent reporting of known CVEs

Watch for

Main branch may be unstable; use releases for production

Migration highlight

CI/CD pipeline integration

Automatically fail builds that contain images with known vulnerabilities

Trivy logo

Trivy

Unified scanner for vulnerabilities, misconfigurations, secrets, and SBOMs

Active developmentPermissive licenseFast to deployGo

Why teams choose it

  • Scans images, filesystems, Git repos, VM images, and Kubernetes clusters
  • Detects CVEs, IaC misconfigurations, secrets, licenses, and generates SBOMs
  • Integrates with CI/CD, GitHub Actions, Kubernetes operator, VS Code plugin

Watch for

Canary builds may contain bugs and are not recommended for production

Migration highlight

CI pipeline vulnerability check

Automatically fails builds when new CVEs are found in container images

Choosing a container security alternative

Teams replacing Sysdig in container security workflows typically weigh self-hosting needs, integration coverage, and licensing obligations.

  • 4 options are actively maintained with recent commits.

Tip: shortlist one hosted and one self-hosted option so stakeholders can compare trade-offs before migrating away from Sysdig.
