Reachability for Python, coming soon to GA 🎉

We are excited to share that Reachability for Python will gradually enter General Availability (GA) across all Snyk environments during the period of December 11th, 2025 to January 12th, 2026.

What is Reachability?

If enabled for your Group or Org, Reachability works by scanning your source code and determining whether the code (e.g. a specific function) that makes a vulnerability exploitable is actually reachable, either directly or transitively.

This contextual risk factor can help you prioritize which issues to prevent or fix first, based on the exploitability risk they pose to your applications.

What's changing with this release?

With the GA release of Reachability for Python, Snyk will automatically detect the reachability of issues across all pip, pipenv, and poetry projects.

If you use Reachability today but have not opted into the Snyk Preview of Reachability for Python, you may notice changes in the Risk Score for issues in these projects due to the inclusion of the reachability risk factor.

You can also expect ongoing Reachability improvements to be released twice monthly for all languages in General Availability, helping to regulate false positives and negatives across your projects.
