1. Is it OK to turn off firewall?
Turning off Microsoft Defender Firewall could make your device (and network, if you have one) more vulnerable to unauthorized access. If there’s an app you need to use that’s being blocked, you can allow it through the firewall, instead of turning the firewall off.
2. Is it better to have firewall on or off?
Turning them off won’t give you any real benefit, so it’s better to leave them on and have that extra layer of protection. If you have any questions about firewalls or computer security, we at Patient Computer Help can assist you with all of your Internet concerns.
3. Why would you turn off a firewall?
Disabling the Windows Firewall on your computer should only be done temporarily to allow downloads or hardware installation. Changes within the network may require you to re-enable Windows Firewall for your computer’s protection.
4. What are the dangers of no firewall?
Without a firewall, the network and connected devices are vulnerable to cyber attacks, hacking, viruses, malware, unauthorized access, data theft, and network disruption. This can result in damage to the system, loss of confidential information, and a decrease in productivity.
5. Does disabling firewall open all ports?
Well, disabling a firewall doesn’t technically ‘open all ports’. A firewall is more like putting window shades on a house, and only opening up the ones you want to let ‘the air or sun’ in.
6. Are firewalls still necessary?
Firewalls provide protection against outside cyber attackers by shielding your computer or network from malicious or unnecessary network traffic. Firewalls can also prevent malicious software from accessing a computer or network via the internet.
7. Is Windows Firewall really necessary?
Bottom line: If you’re on a Windows computer, you should take advantage of what you already have. Windows Defender has good features for personal use in 2021. However, it should not be the only security software or practice you implement on your machine, especially if you’re using your PC for work purposes.
8. Is it important to turn on firewall?
Firewalls provide protection against outside cyber attackers by shielding your computer or network from malicious or unnecessary traffic. It is important to have a firewall enabled to ensure the security of your device and network.

Can hackers get through firewall
A firewall may be secure, but if it's protecting an application or operating system with vulnerabilities, a hacker can easily bypass it. There are countless examples of software vulnerabilities that hackers can exploit to bypass the firewall.
Can a firewall cause internet problems
Any number of factors, including the computer's own security measures, may be the culprit. An obtrusive firewall can prevent computers from interacting, mirroring a network connectivity issue. However, a firewall problem and a network connectivity issue are not the same thing.
Can a firewall stop Internet access
The Windows firewall works like a filter between your PC and the internet, blocking or allowing connections depending on whether or not they're safe. Firewalls will block or allow a lot of traffic automatically, but sometimes you will see a message asking you if you want to allow a program to connect to the internet.

Do I need a firewall if I have a router
Fortunately, most people don't need to buy a firewall. Many devices come with free software firewalls, and many routers automatically have a firewall and additional security protections built in. If you have an older router, however, a separate hardware firewall or an upgrade might be a good idea.

Does a firewall protect my IP address
A NAT firewall doesn't hide your public IP address, but your private IP address. All devices connected to a NAT-enabled router will share a public IP address. The NAT firewall will prevent any online communication that isn't in response to a request you sent from a private IP address.
What can a firewall see
A firewall, at its most basic form, is created to stop connections from suspicious networks. It inspects the source address, destination address, and the destination port of all connections, and decides if a network can be trusted.

First, the basics. What we call a hardware firewall is a security appliance that sits between the modem and the router. It might be standalone piece of hardware, or built into the router itself.
Can we work without firewall
Without a firewall on the network your workstation is on the Internet just waiting for an attack. Once your workstation is compromised, so is your cloud-based data. In short, no firewall means compromised data. A firewall is just one part of a truly effective network security stack.
