A firewall is a security system that helps to protect a business’s computer network from unauthorized access.
This is important because it helps to prevent hackers and other cybercriminals from gaining access to sensitive information, such as financial data and personal information of employees and customers.
A firewall can also help to protect against malware and other types of malicious software that can damage a network and compromise its security. Additionally, a firewall can help to regulate traffic on a network, ensuring that only authorized users and devices are able to access the network and its resources. Overall, a firewall is an important tool for helping businesses to protect their networks and maintain the security of their sensitive information.
