+title: "Strengthening Yeoman: Our 2025 Security Overhaul"
+---
+
+Following our [Security Policy Update](https://yeoman.io/blog/security-policy-update), we’ve completed a **full security review** across Yeoman’s organization.  
+This milestone reinforces Yeoman’s foundation and ensures the project remains **reliable and secure** for the developer community.
+
+## Strengthening Yeoman’s Security
+
+As part of the [Maintenance Reboot Initiative](https://yeoman.io/blog/maintenance-reboot), the team has been hard at work improving processes, hardening infrastructure, and reducing long-term risks.  
+
+Our 2025 security overhaul introduces clear responsibilities, proactive monitoring, and consistent policies across all Yeoman repositories.  
+
+### Key Improvements
+
+- **Organization-wide Security Policy**  
+  A unified [`SECURITY.md`](https://github.com/yeoman/.github/blob/main/SECURITY.md) now defines responsible disclosure and response expectations.  
+  Learn more in our [previous blog post](https://yeoman.io/blog/security-policy-update).
+- **Centralized Resources**  
+  A dedicated [`.github`](https://github.com/yeoman/.github) repository now manages shared templates, documentation, and workflows across Yeoman projects.
+- **OpenSSF Scorecard Integration**  
+  Automated audits and checks are now active across repositories.  
+  Improvements include branch protection, dependency automation, and CI/CD hardening.  
+  See our [OpenSSF Scorecard report](https://github.com/yeoman/.github/blob/main/tools/ossf_scorecard/report.md).
+- **CVE Reviews and Patches**  
+  Known vulnerabilities have been reviewed and mitigated.  
+  See the [analysis discussion](https://github.com/yeoman/yeoman/issues/1779#issuecomment-2656182789).
+- **Threat Model**  
+  A new [Threat Model](https://github.com/yeoman/.github/blob/main/SECURITY.md#threat-model), based on Express and Node.js, outlines potential risks and mitigation strategies.
+- **Access Control Updates**  
+  GitHub and npm permissions were audited to follow the **principle of least privilege**, ensuring tighter access control across the board.
+- **Dependency Updates and Releases**  
+  Outdated dependencies were upgraded, and inactive packages are being refreshed with essential security updates.  
+  Track progress in [issue #28](https://github.com/yeoman/.github/issues/28).
+
+
+## Deprecations and Cleanup
+
+To reduce maintenance overhead and improve overall security, several legacy repositories have been archived:
+- [yeoman/generator-commonjs](https://github.com/yeoman/generator-commonjs)  
+- [yeoman/generator-gruntfile](https://github.com/yeoman/generator-gruntfile)  
+- [yeoman/generator-gruntplugin](https://github.com/yeoman/generator-gruntplugin)  
+- [yeoman/generator-jasmine](https://github.com/yeoman/generator-jasmine)  
+- [yeoman/generator-jquery](https://github.com/yeoman/generator-jquery)  
+- [yeoman/generator-karma](https://github.com/yeoman/generator-karma)  
+- [yeoman/generator-mocha](https://github.com/yeoman/generator-mocha)  
+- [yeoman/Hackathons](https://github.com/yeoman/Hackathons)  
+- [yeoman/yeoman-app](https://github.com/yeoman/yeoman-app)  
+- [yeoman/yeoman-assert](https://github.com/yeoman/yeoman-assert)  
+- [yeoman/yeoman-generator-list](https://github.com/yeoman/yeoman-generator-list)  
+- [yeoman/yeoman-remote](https://github.com/yeoman/yeoman-remote)  
+- [yeoman/yeoman-dummytest](https://github.com/yeoman/yeoman-dummytest)
+
+Most of these repositories relied on outdated dependencies or duplicated functionality already available elsewhere in the ecosystem.  
+Others were for initiatives that no longer are being worked on.
+
+Their respective npm packages have also been deprecated.
+
+## What’s Next
+
+Security work is never truly done. We’ll continue monitoring **OpenSSF Scorecard** results, improving automation, and releasing regular maintenance updates.  
+
+In parallel, we are also going through the plethora of still-active Yeoman packages and updating them to modern Node.js conventions.
+That includes migrating from CommonJS (CJS) to ECMAScript Modules (ESM) and updating their dependencies.
+This will make sure users are able to use the latest versions of both Yeoman and non-Yeoman packages, rather than old and potentially insecure predecessors.
+
+Afterwards, we plan on auditing this documentation website and updating it to reflect all the latest changes in Yeoman.
+Quite a lot has happened since the website was last overhauled!
+
+Community feedback will continue to shape our priorities — your insights help keep Yeoman secure and dependable.
