I am developing a site that will use players from soundcloud, youtube, and audiomack just to name few. I was reading about the sandbox attribute for protecting against some attacks when using iframes . I trust these sites, but still want the comfort of knowing my site won't be in jeopardy for using the iframe players provided by them or any third party. The sandbox attribute seemed like it would do the trick, but gave me problems with some of the players, not to mention older browsers don't support it. is there any other solution I can consider. I'm creating the frames myself with just using the id and api from the respected sites.
