Segment can help collect all your client-side data for Sentry automatically without the need to install Sentry’s client library. Enable Sentry in your Segment settings to asynchronously load Raven.js onto your page without touching the code in your application.
When you call identify, Segment calls Raven.setUserContext by passing in the traits you provided and maps the userId you provided as traits.id.
Read the documentation to get started.
Just look at all the high-quality security 
features all accounts get, regardless of plan.
