They are very dangerous as they transmit what they undercover about you on a web server. A firewall blocks them from the outset, before they have a chance to infect your computer. They are used mainly to prevent hacking. Without firewall security, a hacker could get a hold of your computer and make it a part of what?s called a botnet, which is a large group of computers used to conduct illicit activity, such as spreading viruses.

Allowing them through a firewall, which then has no way to look inside the data stream, could allow any sort of data transfer. Digital certificate is an encryption technology. It does this by using public key and private key information. The digital certificate authenticates the identity of the sender to ensure safer communication and prevent fraud on the Internet. By encrypting communications such as emails, logins or online banking transactions it means that it protects private data and prevent the information from being seen by unwanted people.
