DuckDuckGo

The internet is not merely that which is visible. Behind the easily available sites indexed by search tools such as Google lies the Invisible Web (also referred to as the Deep Web). This huge and almost untouched store of knowledge contains vast collections of material ranging from academic papers and government publications to rare databases and concealed websites.
DuckDuckGo is renowned for its privacy focus, making it a reliable tool for the Deep Web. It doesn’t track your searches or personal information like regular search engines do, providing a safe browsing experience instead. This keeps your online activities private even when you are exploring the unexplored corners of the internet.
Moreover, DuckDuckGo retrieves content from the deep web effectively while maintaining its privacy features. It brings together answers from more than 400 sources, thus providing a comprehensive search experience. Therefore, for anyone who would not like to sacrifice any security measures while venturing into hidden parts of the web that are hard to access, it is a very useful tool. If you are looking into a niche area or invisible sections of the internet, DuckDuckGo provides a secure and thorough option for searching.
