FAQs

A Firewall is a security system designed for the network. A firewall is set on the boundaries of any system or network which monitors and controls network traffic. Firewalls are mostly used to protect the system or network from malware, worms, and viruses. Firewalls can also prevent content filtering and remote access.

Firewall software provides protection from cyberattacks and secures your computer and network from unnecessary network traffic and malicious software. It also improves the security of your computer and protects your private network from malware threats and unauthorized access.

A firewall monitors all the traffic and data that goes in and out of a system. It allows good data and blocks bad data from entering the computer. It uses the following three methods to control the network traffic:

  1. Packet Filtering: which uses pre-determined security rules to create filters and discard the packets which are flagged by the filters.
  2. Proxy Service: which is an application that acts as an intermediary between systems. It creates and runs a process on the firewall that mirrors a service as it runs on the end host.
  3. Stateful Inspection: which is a modern method of firewall scanning. It holds significant attributes of each connection in a database of trusted information. Then it compares the information being transferred to the copy relevant to that transfer held in the database; if the comparison has a positive outcome, the information is allowed; otherwise, it is denied.

Firewall software are widely used by IT professionals, small enterprises, large IT firms, businesses, government agencies, individuals, etc.

  • Security Features
  • Personalization
  • Easy to use and setup
  • Pricing
