Evaluate a Marketplace app's security
Because G Suite Marketplace apps are developed and sold by third-party vendors, Google can't verify the safety of each app. You should install an app only if you trust the app’s developer and vendor. You are solely responsible for any compromise or loss of data that may result from using a Marketplace app. Please see the G Suite Marketplace Terms of Service for more information.
Here are some things you can do to help verify whether an app is trustworthy, before installing:
- Look at customer reviews and ratings (available for all Marketplace apps).
- Contact the vendor directly with any questions.
Gmail contextual gadgets are a special class of gadgets that extract data from a message and provide contextually relevant information to your users in the message pane.
A poorly written gadget may have vulnerabilities, and expose your users to risks, including phishing attacks and data loss. Only install gadgets that you trust.
