Kubescape
AI-powered workflows
Why teams pick it
Security engineers needing compliance checks against multiple frameworks
All open-source alternatives
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.
Clair
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
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.
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
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.
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.
