  <h2>Tor for everything</h2>

sajolida's avatar
sajolida committed

  <p class="big">Everything you do on the Internet from Tails goes through the Tor

  network. Tor encrypts and anonymizes your connection by
sajolida's avatar
sajolida committed
191
  <strong>passing it through 3 relays</strong>. <i>Relays</i> are servers
192
  operated by different people and organizations around the world.</p>
193

sajolida's avatar
