VPN vs Firewall
Summary: Difference Between VPN and Firewall is that the secure connection created over the Internet between the user’s computer and the company’s network is called a VPN tunnel. Many companies allow external access to their internal networks only via a VPN connection. While a firewall is hardware and/or software that protects a network’s resources from intrusion by users on another network such as the Internet. All networked and online computer users should implement a firewall solution.
VPN
Many companies today allow access to their company networks through a virtual private network. When a mobile user, remote office, vendor, or customer connects to a company’s network using the Internet, a virtual private network (VPN) provides them with a secure connection to the company network server, as if they had a private line. VPNs help to ensure that transmitted data is safe from being intercepted by unauthorized people.
VPNs securely extend the company’s internal network beyond the physical boundaries of the company. The secure connection created over the Internet between the user’s computer and the company’s network is called a VPN tunnel. Many companies allow external access to their internal networks only via a VPN connection.
Firewall
A firewall is hardware and/or software that protects a network’s resources from intrusion by users on another network such as the Internet. All networked and online computer users should implement a firewall solution. Organizations use firewalls to protect network resources from outsiders and to restrict employees’ access to sensitive data such as payroll or personnel records. They can implement a firewall solution themselves or outsource their needs to a company specializing in providing firewall protection. Large organizations often route all their communications through a proxy server, which is a component of the firewall. A proxy server is a server outside the organization’s network that controls which communications pass into the organization’s network.
Home and small office/home office users often protect their computers with a personal firewall utility. A personal firewall is a utility program that detects and protects a personal computer and its data from unauthorized intrusions. Some operating systems, such as Windows, include personal firewalls. Some small office/home office users purchase a hardware firewall, such as a router or other device that has a built-in firewall, in addition to or instead of personal firewall software. Hardware firewalls stop intrusions before they attempt to affect your computer maliciously.
