DockSec vs Docker Scout
Docker Scout is built into Docker Desktop and Docker Hub, which makes it the path of least resistance for anyone already in that ecosystem. That convenience is real and worth weighing.
Comparison
| Docker Scout | DockSec | |
|---|---|---|
| Setup | Already installed with Docker Desktop | pip install docksec |
| Account required | Docker Hub account for most features | No |
| Where analysis runs | Largely server-side | Entirely local |
| Base image recommendations | Yes, and good | Digest pinning only |
| Policy evaluation | Yes, via Docker Hub | Local config file and waivers |
| Compose topology analysis | No | Yes |
| Cross-service exploit chains | No | Yes |
| Automatic Dockerfile repair | No | Yes |
| EPSS tiering | Partial | Yes, four tiers, carried into SARIF |
| Works without Docker Hub | Limited | Fully |
| Licence | Proprietary | MIT |
Where Docker Scout is the better choice
- You want zero setup. It is already there.
- You want base image recommendations. Scout's suggestions for a less vulnerable base are genuinely useful and DockSec does not offer an equivalent.
- You are entirely inside Docker Hub and want policies alongside your registry.
Where DockSec is the better choice
- You cannot send images or findings to a third party. Scout's model assumes Docker Hub; DockSec assumes nothing leaves.
- You run Compose stacks. Scout analyses images. DockSec analyses the relationships between services, which is where the interesting failures are.
- You are not on Docker Desktop. Scout is least useful outside it; DockSec is a Python package and a container image.
- You need the output in CI, ranked. DockSec's exit codes,
--fail-ongating and SARIF with EPSS are built for a pipeline rather than a desktop.
Using both
Reasonable. Scout for base image recommendations during development, DockSec in CI for gating, chains and offline operation. They overlap on CVE detection but their strengths sit in different places.
