Check Plugin Not in WordPress Plugin Directory

Subscribers of our service can submit ZIP files of plugins that are not in the WordPress Plugin Directory to have them checked. (Not all issues can be checked for with uploaded plugins, as they require data not available with just the plugin's files.) You can sign up for the service for free here. For existing subscribers, once you are logged in to your account, return to this page to access that functionality.

The results of these gradings will not be stored.

About the Scorecard

The Plugin Security Scorecard grades plugins' handling of security based on data coming from the Plugin Vulnerabilities service, checking over the contents of the plugin, the WordPress.org API, and data generated specifically for the tool. It provides a useful, but incomplete, understanding of the security posture of the plugin and its developer. All the issues identified are ones that the developer of the plugin has the ability to address to get the grade of the plugin up to an A+.

Grades are calculated based on issues with any of the following:

• Plugins known to be vulnerable
• Plugin developers with track records of improperly handling security problems
• Security issues in the plugin that can be detected in an automated fashion
• Issues with the developer's developerment processes that suggest that their could be problems with security
• Plugins making unsupported, misleading, and false claims about their handling of security and the handling of security with WordPress

We are working to expand and refine the tools' ability to provide a good measure of plugins' security status. If you are aware of an additional security concern with this plugin that isn't represented here, please contact us. Other feedback on the tool is also welcome.

If you want a comprehensive understanding of the security of the plugin, a well-done security review is really needed to provide that.
