I have tried to embed GoodData into iframe, however the site does not show and I can see some errors in the browser console - Refused to display 'https://mycompany.na.gooddata.com/' in a frame because it set 'X-Frame-Options' to 'sameorigin'.

When embedding pixel-perfect dashboards, KPI dashboards, or Analytical Designer, you need to construct the URL for an embedded object. Unfortunately, it is not possible to embed the full GoodData Portal and that is why you see the error. There are dedicated resources for embedding.
