The announcement of each breach, like the Home Depot breach discussed in this CIO article, reinforces the simple reality that if data exists on a system, it can be compromised. No systems are perfect. But, by no means does this reality suggest it’s time to give up. Instead, it stresses the importance of finding better ways to secure access to our most crucial data environments.

For instance, putting the browser in an isolated subsystem ensures that any compromise does not provide access to valuable data. Security can never be tacked on after the fact any more than structural defects in a building can be addressed with spackle and paint. Security needs to be at the core of design decisions. That is why normal browsers are vulnerable and why Passages is secure.
