Firewall
Nexus Firewall is your first line of defense against dangerous open source components. It provides tools to keep risky components from entering your software supply chain, allowing you to proactively manage your risk while accelerating development by reducing rework.
Nexus Firewall is powered by IQ Server, which also powers Nexus Lifecycle and Auditor. See Licensing and Features to learn more about our products and solutions.
Nexus Firewall is a solution that prevents bad components from entering your software supply chain. When new components are downloaded, Firewall every new package against a set of organization-defined policies. Any component or dependency that violates one of these policies is then blocked from your repository.
