A remote access gateway is a device or service that enables users to securely connect to a corporate or private network from remote locations, such as home or while traveling. It acts as an entry point, authenticating users and encrypting data to protect sensitive information as it travels over the internet. Remote access gateways often use technologies like VPN (Virtual Private Network) or SSL (Secure Sockets Layer) to ensure secure communication. This solution allows employees, partners, or contractors to access internal resources, applications, and files as if they were physically present in the office, enhancing productivity while maintaining robust security controls.
