A Firewall is a Internet Security Software that helps you protect your devices from malware while using the internet. It can be used for Desktop Computers, Laptops, Tablets & Mobile Phones.
Here are top 5 Advantages of using a Firewall on your PC & other devices.
Blocking programs from internet access:
A Firewall stops programs from sending unauthorized data without user permission. Users can also manually block programs and services from connecting through the internet.
Hides user identity:
Proxy Firewalls protect user identity by hiding their original IP address while sending a request to the internet.
Monitor Traffic:
One of the best features of a Firewall is that it monitors all incoming and outgoing traffic.
Protection against Malware:
Firewalls also block traffic from untrusted sources that may contain malware. Hardware-based Firewalls can protect all the devices in your home or office.
Prevents Hacking:
All the internet data must pass through the Firewall, whether it is incoming or outgoing. The Firewall immediately blocks suspicious files coming from unknown sources.
Important Tips:
While installing some programs like Download Manager and Torrent, the setup asks you to add an exception of that program in Firewall. You should allow it only if you trust the software and files downloaded from it.
A Hardware-based Firewall only prevents the virus from entering your network. But, if any of your homegroup PCs are affected by viruses through a pen drive or other sources, the virus can spread on other devices.
