Software supply chain attacks are on the rise. If your build system automatically pulls the latest version of a library from a public repository, you are vulnerable to compromised upstream packages. An exclusive repository acts as a firewall. You only host packages that have been scanned for vulnerabilities and license compliance. 📦 2. Guaranteed Build Reproducibility
To enforce exclusivity, you must remove the default public remotes and add your private server. Run the following commands on your developer machines and CI/CD agents: conan repository exclusive
Self-hosted or managed servers used by organizations to host internal proprietary code and verified third-party binaries. Understanding the "Exclusive" Repository Strategy Software supply chain attacks are on the rise
Public repositories can change. A package might be removed, or a recipe might be updated, causing your builds to fail unexpectedly. By hosting all required packages exclusively on your own server, you ensure that a build run today will yield the exact same results five years from now. 🚀 3. Optimized Network and Build Speeds You only host packages that have been scanned
The industry standard for Conan, offering native support, advanced replication, and security scanning (via JFrog Xray).
Use a pipeline that promotes packages from a "dev" repository to a "testing" repository, and finally to a "release" repository only after passing rigorous automated tests. Conclusion
Organizations building closed-source software cannot upload their packages to public servers. Private, exclusive repositories allow teams to share compiled binaries across different departments and projects without exposing intellectual property to the public.
