O3 Security Image Scanner

Purpose: O3 scans container images for OS vulnerabilities, malicious layers, embedded secrets, and misconfigured permissions before registry push.
Image formats: The scanner works with Docker, OCI, and distroless images.
Layer inspection: O3 decomposes and inspects every image layer, including OS packages, application code, credentials, and layer changes.
Malware detection: O3 compares added binaries against known-good hashes and detects malicious signatures, unexpected cron jobs, startup scripts, and obfuscated shell scripts.
Secret detection: O3 detects secrets that remain in earlier layers even after later deletion, including API keys, database credentials, and private keys.
Registry integrations: The image scanner integrates with Amazon ECR, Google GCR and Artifact Registry, Azure ACR, Docker Hub, and private registries using Docker Registry API v2.
SBOM output: Each scan generates SBOM output in CycloneDX and SPDX formats.
Vulnerability intelligence: O3 matches packages against NVD, OSV, and distribution-specific advisories and reports CVSS, exploitability, fix version, and introducing layer.
Promotion blocking: The registry integration can block promotion to a production registry when critical findings are present.
Integrations: O3 lists more than 30 native integrations across CI/CD, code editors, package managers, cloud, ticketing, and registries.
Security certifications: O3 states that it is SOC 2 Type II and ISO 27001 certified, with audit reports available on request under NDA.
Data protection: O3 states that data in transit uses TLS 1.3, data at rest uses AES-256, and production access is restricted, logged, and reviewed.
Deployment: O3 states that it offers self-hosted deployment inside a customer VPC or air-gapped environment with no outbound telemetry required.
