Sls header plain

Step onto any city street and you may find yourself subject to numerous forms of police surveillance—many imperceptible to the human eye.

Two-factor authentication (or 2FA) is one of the biggest-bang-for-your-buck ways to improve the security of your online accounts. Luckily, it's becoming much more common across the web.

Several journalists and experts have recently focused on the fact that a scanned document published by The Intercept contained tiny yellow dots produced by a Xerox DocuColor printer.
