- Omniquad Personal Firewall
- License: Freeware

Omniquad Personal Firewall is a personal security system to protect your computers from unauthorised access over the LAN and / Internet. Personal Firewall is a software application used to protect a single Internet-connected computer from intruders. Personal firewall protection is especially useful for users with "always-on" connections such as DSL or Cable modem. Such connections use a static IP address that makes them especially vulnerable to potential hackers . Often compared to anti-virus applications , personal firewalls work in the background at the device (link layer) level to protect the integrity of the system from malicious computer code by controlling Internet connections to and from a user's computer, filtering inbound and outbound traffic, and alerting the user to attempted intrusions.
