That’s a very valid concern. Even if the cloud provider is secure, the ‘middle’ part of the journey—the ISP and the various nodes your data passes through—can be a weak link. I always make sure my encrypted tunnel is active before I start a bulk upload of my client projects. It’s especially important if you’re working from a mobile hotspot or a shared home connection. It takes just a second to turn on, and it’s a very low-cost way to ensure that your private documents aren’t exposed to anyone monitoring the local network traffic.
