There is a policy response that needs to occur. There is also a technical response that needs to occur. It is the development community that can really craft the solutions and make sure we are safe.

[Brazil] went to the UN and said, "We need new standards for this." We need to take a look at what they're calling "data sovereignty."

As a general rule, US-based multinationals should not be trusted until they prove otherwise. This is sad, because they have the capability to provide the best and most trusted services in the world if they actually desire to do so.

The internet exchange is sort of the core points where all of the international cables come together, where all of the internet service providers come together, and they trade lines with each other. These are priority one targets for any sort of espionage agency, because they provide access to so many people's communications.
