Oct 1, 2024In October 2024, delivered key enhancements to the Domain and Vulnerability Search features in cisagov/XFD. The work refactored search logic to improve filtering and sorting, enabling more precise data retrieval for relevant stakeholders. Export readiness was advanced by stubbing CSV export methods for domains and vulnerabilities, establishing a clear scaffold for future CSV and S3 export integration. Debugging output was cleaned up as part of the refactor, improving maintainability and reducing log noise. Commits captured the changes, including merging search_domains/search_vulnerabilities and stubbing export methods, and adding a TODO for export function integration with CSV and S3 when available. This set of changes positions the project for faster, more reliable data exports and supports future analytics and reporting requirements.
