What are scheduled rescans?

Re-analyzing code on a schedule even when nothing has changed, to catch newly published vulnerabilities.

By Cláudia FernandesUpdated 2026-10-02

Your dependencies do not have to change for your risk to change. A package that was clean at merge time becomes vulnerable the moment an advisory is published, and commit-triggered scanning alone will never notice.

Continuous rescanning closes that gap. For a stable service that is rarely deployed, sometimes one running a critical workload, it is frequently the only thing watching for new CVEs at all, unless someone monitors an SBOM of the deployed build. The cost is alerts landing on repositories nobody is actively working on, so routing needs thought.

What to look for

Rescan frequency, and whether it is configurable
How alerts are routed when nobody is actively working on the repository
Whether rescanning covers deployed artifacts as well as source
Which plan tier includes it, since this is frequently gated

Best 19 code quality, security and code review tools with scheduled rescans

Every tool in the directory whose documentation covers this, 12 fully and 7 partially. Full support is shown first. Shown in a random order that changes on every visit, so no tool gets an advantage from its position.

Support is not the same as parity, since some implementations are narrower in scope, gated to a higher plan tier, or maintained only for existing customers. The note under each tool is what its own documentation describes.
