Why do you need a firewall?

A connection that allows data exchange between two computers is a network. Once you connect your computer to a local or global network, your computer automatically becomes a potential target for network scammers. Don’t think that you are safe if nobody knows you, or if you don’t work for a large company, or if you just don’t have a lot of money. The people who commit crimes on the Internet are looking for any opportunity to use any computer connected to the Internet that they can find.

A firewall is a program that serves as a shield between your computer and the outside world. Hackers use special software to scan the Internet and search for unprotected computers. These programs send a small data packet to your computer. If there isn’t a firewall installed on the computer, it automatically replies to the incoming message and the hacker understands that the system is vulnerable and can be broken in. But a firewall installed on the computer detects these packets and does not reply to them. Thus, hackers cannot even find out that your computer is connected to the network.

Malicious applications can be installed on an unprotected computer and run unnoticed. They can:

Collect and send your personal information (bank details, passwords, credit card numbers, etc.) to those people who created them or just delete some important data.
Use the infected computer to send spam, distribute viruses, hack remote services, or just carrying out other illegal activities.
Generate a large amount of unwanted traffic and use the modem to make pay calls.
Show popup ads and redirect the Internet browser to advertising pages.
Replace the pages of well-known sites with their own pages and use it for financial fraud (so-called phishing).
Cause other software and operating system malfunctions.

On the local area network, a scammer can use special types of attacks to get all the data that is sent over the network from your computer. ICQ messages, mail passwords, messages and other private data can be intercepted before they reach the recipient. Even if you use protected connections (SSL), there are ways to get intercepted data in an unencrypted form.

The personal firewall AGAVA Firewall is designed to reliably protect your computer from scammers and ensure that you work comfortably when you are connected to the Internet. Your workstation remains unprotected inside your local area network that is protected by the corporate firewall from outside threats. As a general rule, the configuration of the common firewall does not allow you to allow or block particular applications running on the workstation as well as to prevent viruses from spreading.

AGAVA Firewall provides you with full control over the entire network activity and automatically prevents known types of attacks.

AGAVA Firewall scans all the data transferred over the network and gives you full control over the situation so that you can decide what can be transferred and what not. Besides the possibility to specify rules, AGAVA Firewall provides you with automatic protection methods against various types of network attacks. The firewall controls network applications running on the computer and prevents programs infected by viruses from sending and receiving data over the network.

You can monitor network connections and applications that are being created in real time. Network events are logged and you can use this log to analyze possible problems.

Tools provided by the firewall allow you to protect your computer against attacks and network viruses both on the Internet and on the local area network.
