Harness your existing Container Image Vulnerability Scanning information to your Kubernetes Cluster. iskan enables you to:
- Plug one or more container image vulnerability providers such as ECR, GCR, Azure, Harbor and others
- Analyse the running Pods and their containers for known vulnerabilities.
- Control the scan scope to certain namespaces
- Filter scan results by: Severity, CVSS Score, Fixable CVEs, and even snooze specific CVEs.
Supported Vulnerability Scan Providers
- AWS ECR
- GCP GCR
- Azure ACR (Preview)
- Rapid7 InsightVM (Preview)
- Harbor - v2.0 API
- Inline Local Scanner - Trivy (Experimental)
