Provider data is maintained in provider.yaml and compiled into sources_data.json, making the project a compact data-and-code package for infrastructure detection. ### Adoption history Its adoption is tied to ProjectDiscovery's security tooling ecosystem, where small composable CLIs are used in reconnaissance and asset analysis pipelines. The README documents both direct CLI use and library import via github.com/projectdiscovery/cdncheck. ### How it is used Users run cdncheck against IP or DNS input, filter results to CDN, cloud, or WAF matches, write plain or JSONL output, and can add providers through the repository's provider data workflow. ### Why package nerds care cdncheck is package-nerd-relevant because it packages frequently changing provider intelligence into a Go CLI/library with reproducible releases; the package value is as much the curated data as the executable. ### Timeline - 2020: GitHub repository metadata identifies projectdiscovery/cdncheck repository creation era. - 2020s: README documents CDN, cloud, WAF detection, provider generation, CLI flags, and library usage. ### Related projects - cdncheck belongs to the ProjectDiscovery ecosystem of reconnaissance and security tools and is commonly adjacent to DNS, HTTP probing, and asset-enrichment workflows. ### Sources - - - - - ## Security Notes No matching local secret-handling manifest was found for cdncheck.
