What is a firewall and why do I need one? The Verizon Internet Security Suite includes a firewall to help prevent intruders from accessing your system when you are online.
Note:: The Verizon Internet Security Suite is available for an additional monthly charge. A firewall is a security feature designed to help protect your computer and personal data from unauthorized external access and alert you to immediate threats. A firewall examines all incoming and outgoing Internet traffic and allows only traffic that meets the security policies that were set up. Internet traffic that does not meet these security policies is blocked by the firewall and never reaches your computer.
Verizon Broadband has two things hackers love: high-speed access and dedicated connections.
