Overview
WhiteSource Diffend detects and blocks malicious dependency updates.
Diffend acts as a shield between you and the wild world of open-source libraries, allowing you to define policies around the usage of libraries and their versions. Under the hood, we run WhiteSource runs extensive security checks to find potential vulnerabilities and exploits.
When you run your package manager commands with our plugin, all of this knowledge, policies and research is are combined into one easy-to-understand verdict that you or your security team can use to control and mitigate potential problems before they hit production. The Diffend heuristics learn with each package release, and whenever we discover anything is discovered that would could pose a threat to your organization, we WhiteSource will notify you about it.
