Ask HN: When do External Data Analytics tools win trust?

I had discovered chart.io shortly after starting our venture, and found it extremely useful for building a dashboard for our apps usage (we didn't want to spend time and effort ourselves to build a beautiful internal dashboard, and we did not think the data we wanted to run it on was super-secret). We still use it. When I discuss this with friends working with companies that have grown to worry about the competitive value of their data, they either struggle to build internal continuously changing dashboards, or invest in tools like Pentaho that require much investment. But how and when do External Data Analytics or Dashboard tools win trust? Is their field of play mainly restricted to data that companies do not see as risky if leaked? Or do they gradually move up the ladder?
