Netscape Security Wrapper manages the loading of NPAPI (Netscape Plugin API) plugins and applies simple policy decisions. The intention is to allow administrators to deploy deprecated, unreliable, or unsafe third party plugins while minimizing the security exposure. Safari, Google Chrome, Firefox, and other NPAPI-compatible browsers are supported on OS X and Linux. Use cases include: restricting plugins to certain domains, restricting the use of deprecated plugins to known outliers, allowing internal corporate workflows which use insecure or deprecated plugins without exposing the plugin to the hostile Internet, and allowing multiple outdated plugin versions (e.g., Java) to co-exist for use in whitelisted, trusted enterprise tools.
