Avoid allowing developers to pull random, un-vetted packages from the web. If a project requires a new open-source library, have a security team approve it, proxy it through your exclusive remote cache, or internalize the recipe under your own company namespace.
In Conan 2.x, you can view and configure remote properties using the conan remote command.
Whether you are using Conan Center Index or a private artifact repository, pre-built binaries for various configurations can be included. This ensures that end-users receive a ready-to-use package without the need for additional downloads. SDKs can be shared between different work groups without exposing internal details.
In the context of (the C/C++ package manager), the term "exclusive" typically refers to a configuration policy or a repository mode that restricts how packages are consumed or uploaded. conan repository exclusive
Let's walk through how to set up and enforce an exclusive repository strategy using both JFrog Artifactory (server-side) and Conan 2.0 (client-side). Step 1: Set Up Server-Side Exclusivity in Artifactory
: Navigate to Administration -> Repositories -> Repositories , click "Add Repositories," select Local Repository , choose Conan as the package type, give it a key (e.g., conan-local ), and click Create Local Repository .
A team is developing a proprietary 3D rendering engine that depends on several internal libraries. They want to share an SDK with external partners without exposing the source code of these dependencies. Avoid allowing developers to pull random, un-vetted packages
Understanding the theory is important, but seeing how an exclusive repository functions in practice is what truly clarifies its value. Here are two archetypal scenarios.
: Ideal if your code is already on these platforms. GitLab provides a built-in Conan registry. Conan Server
Even with a great setup, teams encounter friction. Here are solutions to frequent issues with an exclusive Conan repository: Whether you are using Conan Center Index or
Conan's "Repository Exclusive" mode enhances build security and speed by restricting package searches to designated, single repositories for specified packages. This feature prevents dependency confusion attacks and ensures reproducible builds by pinning package patterns to secure remotes, improving upon the default broad search behavior.

Public repositories face risks from typosquatting, malicious code injection, and sudden package deletions. An exclusive repository eliminates external variables. Your build system interacts only with code your organization owns, audits, and approves. Reproducible Builds and Binary Stability
Dependency confusion (or a substitution attack) occurs when an attacker registers a malicious package with the same name as an internal, proprietary package on a public repository (like ConanCenter). If a build system queries the public remote before or alongside the internal remote, it might inadvertently pull the higher-versioned malicious public package into the software supply chain.
