It's tempting to imagine that few online safeguards will stop NSA surveillance in its tracks, but that's not true. A new leak from Edward Snowden's files reveals that there's a surprising number of ways to thwart these snoops, at least as of 2012. While you may already know that the NSA sees Tor's anonymity network as a problem, it hates the heavy encryption on chat protocols like CSpace or Off-the-Record, internet calling systems like ZRTP or highly secure email systems like Zoho. Use two or more of these services in tandem and you may as well disappear completely -- the NSA considers the combination a "near-total loss."
