Among the tips that can be given to navigate safely in the Deep Web, we can cite:
Do not use Windows, Android or iOS to browse the Deep Web. They are not as secure as Linux or Mac OS could be. Instead, use a tool that has the Tails operating system.
Use current software to surf the Deep Web, otherwise your identity is exposed or you may be a victim of cyber attacks.
It is not recommended to modify the default settings of the browser, as this could compromise security and privacy online.
Do not download any file once inside the Deep Web, unless you know exactly what you are going to download. In this sense, it is possible that certain files contain some kind of script and that may reveal the user’s identity to a third party.
Do not enter personal mail when browsing the Deep Web.
