Epic is another Chromium-based browser that, like the others here, aims to improve security and privacy by enabling more secure default options and throwing in a few surprises of its own.
These include Search Protection, which activates automatically when visiting a search engine like Google. In this mode all requests are sent via a US-based IP to hide your own, however you can also toggle this on at any time with any website. It's also perennially in 'private' mode, where no personally-identifiable data is saved locally from a browsing session, similar to WhiteHat Aviator (e.g, you can't save a session to restore next time).
And, as we've come to expect from security and privacy-focused browsers, any form of user-based tracking is automatically blocked as are third-party cookies to prevent tracking you between sessions, while HTTPS is the default preferred mode when available. However it also boasts an in-built ad-blocker based on AdblockPlus blacklists that are regularly updated, as well as allowing you to add your own lists.
As Epic's defaults are quite stringent it does come with an interesting addition we haven't seen in the other browsers: the ability to toggle various features right from the toolbar with the umbrella 'Unified Button'. This includes allowing plugins, encrypted data, ad networks and trackers, and adblocking, making it easy to get a site working as intended if Epic's protection turns out to be overbearing.
Finally, Epic defaults to using its own privacy-orientated search engine, epicsearch.in. Like similar search engines (see Secure Search), it proxies your searches to hide personally-identifiable information like your IP and uses HTTPS to encrypt all communication.
