AWS Continuum now offers a post‑deployment gate that automatically launches an AI‑driven penetration test limited to the code change you just pushed. By embedding this gate in a CI/CD pipeline you can halt promotion to production whenever Continuum confirms an exploitable vulnerability, turning security validation into a per‑deployment checkpoint.
Why scoped testing is practical
Continuum determines the commit range for each run – the head commit being the change under test and the base commit the last one that cleared the gate. Only the files that altered the attack surface are examined, which keeps the execution time and cost low enough to run on every push. The service returns one of three scope decisions: in scope (the change affected the surface and findings are evaluated), scoped out (no security‑relevant change, pipeline passes), or scope conflict (the change fell outside the configured range, leaving the decision to the pipeline owner). Because the gate blocks on findings that Continuum has validated as exploitable, a failing pipeline signals a real vulnerability rather than a pattern match.
Gate architecture and data flow
The pipeline first deploys the change to a staging environment that Continuum can reach. A gate step then authenticates to AWS using OpenID Connect (OIDC) and assumes an IAM role you have created for the pipeline. With that role the step calls Continuum’s API, passing the Agent Space ID (as‑…) and penetration test ID (pt‑…). All scanning runs inside your AWS account; no penetration‑testing code executes on the CI runner. Continuum evaluates the scoped change, returns the scope decision and any findings, and the gate step either allows the workflow to continue or blocks promotion to production based on the severity threshold you configured.
Implementing the gate
Three actions are required:
- Configure a penetration test: Follow the one‑time setup in the Continuum documentation – verify the target domain, create a test in your Agent Space, enable CI/CD mode, and link your repository. Record the Agent Space ID and test ID for later use.
- Create an IAM role: Your AWS account must have permission to create an OIDC identity provider and an IAM role that the pipeline can assume. The role needs the permissions required by Continuum to start a test and read results.
- Add the gate step: Insert a step into your pipeline that performs the OIDC authentication, assumes the role, and invokes Continuum with the recorded IDs. The pattern is supported on GitHub Actions, GitLab CI/CD, Bitbucket Pipelines, and Azure DevOps Pipelines; the example in the source uses GitHub Actions.
Operational and security implications
Because the scan runs server‑side, the CI environment does not need any penetration‑testing binaries or credentials beyond the OIDC token. However, the IAM role must be scoped tightly to the minimum actions required by Continuum, and the staging environment must be reachable from the AWS account. Teams should define a severity threshold that aligns with their risk appetite; findings above that level will block the pipeline. Scope‑conflict decisions require a policy – either treat them as a pass or as a block – depending on how much you trust the change to stay within the defined surface.

What This Means For Practitioners
- Adopt the gate when you need exploitable‑vulnerability confirmation on every change, not just periodic manual pentests.
- Ensure your CI/CD system can perform OIDC authentication and that the IAM role follows the principle of least privilege.
- Validate that your staging environment is reachable and mirrors the production attack surface closely enough for meaningful results.
- Define clear policies for severity thresholds and scope‑conflict handling to avoid unexpected pipeline failures.
- Monitor the Continuum console for scope decisions and findings to maintain visibility into which commits introduced risk.
