Our verdict on O3 Security Image Scanner

O3 Security Image Scanner examines Docker, OCI, distroless and minimal container images layer by layer. It is aimed at security teams that need to inspect both image contents and how those contents entered an image, including teams working across small, mid-market or enterprise environments. Findings cover operating-system and application vulnerabilities, malicious binaries or scripts, embedded secrets, permission misconfigurations and provenance deviations. The emphasis is on detailed image analysis rather than a general-purpose security workflow.

The scanner’s depth is its clearest distinction. CVE matching includes the vulnerable package and the layer that introduced it, while secret discovery checks image history, including secrets deleted in later layers. It also looks for obfuscated scripts and unexpected startup or cron activity, and analyzes binaries in distroless and scratch images. Registry scans can run on push, pull or a recurring schedule; critical findings can block promotion. CycloneDX and SPDX SBOM generation supports teams that need software inventory alongside scan results.

O3 connects with Amazon ECR, Google GCR and Artifact Registry, Azure ACR, Docker Hub and GitHub Packages, as well as CI systems including GitHub Actions, Jenkins, GitLab CI, CircleCI, Bitbucket Pipelines and Azure DevOps. Its cloud integrations span AWS, Google Cloud and Azure. This breadth suits teams with mixed registries or pipelines, while buyers looking for a non-web platform should note that web is the listed platform. The contact-sales pricing model is less suited to buyers who need a self-serve purchase path. Choose O3 when layer-level analysis, registry automation and image promotion controls matter; consider alternatives if those capabilities exceed your scanning needs.
