We’re thrilled to announce the relaunch of Surveillance Self-Defense (SSD), our guide to defending yourself and your friends from digital surveillance by using encryption tools and developing appropriate privacy and security practices. The site launches today in English, Arabic, and Spanish, with more languages coming soon.

SSD was first launched in 2009, to “educate Americans about the law and technology of communications surveillance…” and to provide information on how to use technology more safely. Not long after, in the midst of the 2009 Iranian uprising, we launched an international version that focused on the concerns of individuals struggling to preserve their right to free expression in authoritarian regimes.

In the time since the Snowden revelations, we’ve learned a lot about the threats faced by individuals and organizations all over the world—threats to privacy, security, and free expression. And there is still plenty that we don’t know. In creating the new SSD, we seek to help users of technology understand for themselves the threats they face and use technology to fight back against them. These resources are intended to inspire better-informed conversations and decision-making about digital security in privacy, resulting in a stronger uptake of best practices, and the spread of vital awareness among our many constituents.

We invite you to take a look at SSD, and to provide us with feedback (we’ve made it easy: there’s a feedback dropdown on every page). Right now, the site is available in just three languages, but we soon plan to expand, with Vietnamese, Russian, Persian, and several other languages in our sights. And if you think we’ve missed something, please let us know. The threats are always changing, so our advice should change to keep up.
