Tor Network
The Onion Router, commonly referred to as Tor, is one of the safest ways to browse the internet anonymously. Tor is an open source browser that takes you to your destination browser through multiple nodes and hops. These nodes are remote computers of volunteers who form a network. Each website is accessed through a random network of nodes, making it difficult for anyone to trace your location.
PGP
Emails are one of the most common targets of attacks for hackers to gain access to your system and sensitive information stored in it. PGP has been the most trusted email encryption software in the market for over two decades now. Its new version, GPG, is open source and more user friendly.
Ad-Block Plus
Perhaps one of the most widely used ad blocking tools in the world, Ad-Block Plus is a great way to protect tracking cookies from being installed on your system. Although it does not protect you from malicious websites, it blocks ads and prevents them from installing tracking cookies on your system, which is quite helpful.
VPN
VPNs are arguably one of the best security tools at your disposal. They mask your IP address with one of their own server’s IP address and encrypt all traffic exchanged between the internet and your system. This enables them to help you browse the internet safely as well as anonymously. Additional features like Tor over VPN are great tools to ensure ones privacy online.
Tails OS
Tails OS is a Linux-based OS that is one of the best methods to truly be anonymous and safe while browsing the internet. Edward Snowden himself rated it quite highly, which more than speaks for its credentials in offering online security.
Signal
Developed by Open Whisper Systems, Signal is an encrypted instant messaging and voice calling application for Android and iOS users. It ensures that your messages and video calls are not monitored by anyone as it encrypts all data shared.
OpenDNS
OpenDNS provides protection against malware and botnets. It simply switches your DNS settings to offer high grade protection while maintaining your connection speed.
SpiderOak
