A VPN Gateway is a network device that allows secure connections between different networks over the internet. It creates a virtual private network (VPN) that encrypts data, ensuring that sensitive information remains private while traveling across public networks. This is particularly useful for businesses that need to connect remote employees or branch offices securely. In addition to providing security, a VPN Gateway can also help bypass geographical restrictions by masking the user's IP address. This allows users to access content that may be blocked in their region. Overall, a VPN Gateway enhances both security and accessibility for users and organizations.
