"Access" is not what you think it means. This is marketing hype directly from their site. I have first hand experience using their extractors and its not as robust as they make it sound. They extract metadata outside of the encrypted volumes. It all depends on what your worried about.

Actual hardware 0-days are highly coveted, extremely expensive, military classified tools that TSA does not have access too and never will.

Edit: CBP not TSA (thanks good callout)
