Smart Firewall:
A shield for your online safety

A firewall monitors network traffic, enforces rules about which traffic is allowed or blocked, and helps block unauthorized access to your computer. It helps block hackers or malware from entering your device over the network.

A firewall protects you from unsolicited and unwanted incoming network traffic. It evaluates incoming traffic for malicious threats, such as hackers and malware, to prevent them from infiltrating your computer or network.

Most computers come with a built-in firewall, such as Windows Defender Firewall or macOS Firewall. Norton Smart Firewall adds stronger, two-way protection that monitors both incoming and outgoing connections, blocking suspicious apps and helping prevent cyberthreats that built-in firewalls can miss.

Firewalls inspect data to keep your connection safe, but the Smart Firewall from Norton is designed to do this efficiently, so you have protection without noticeably slowing down your internet speed.

Windows Firewall offers basic protection, but the Smart Firewall from Norton adds advanced features like two-way traffic monitoring, intrusion prevention, and intelligent threat detection. It’s built to work seamlessly with the other features offered by the security suite of Norton, to give you stronger, more comprehensive protection online.

A cybercriminal can potentially hack any device or system connected to the internet. Firewalls are more susceptible to being hacked if they’re poorly configured, running outdated software, or zero-day vulnerabilities arise.

Firewalls don’t protect against viruses on their own. They manage access to your network, whereas antivirus software serves as cyber protection from malicious viruses. However, some software firewall suites, like Norton 360 Deluxe, include virus protection.

Yes, your home needs a firewall. Without a firewall, you could leave yourself open to accepting every connection to your home network without a way to detect and reject incoming threats. Intruders could engage in malicious activities like gaining control over your computer or network, deleting your data, or using your personal information to commit identity theft and other online frauds.
