To securely access shared files and corporate email from home, the best tool to use is a Virtual Private Network (VPN). Here's why:
* VPN (Virtual Private Network): A VPN creates a secure connection over the internet, allowing the user to access the corporate network as if they were on-site. It encrypts the data transmitted between the user's home and the corporate network, ensuring privacy and security.
* MSRA (Microsoft Remote Assistance): Used for remote support but not for accessing shared files and emails securely.
* FTP (File Transfer Protocol): Used for transferring files but does not provide secure access to a corporate network or email.
* RMM (Remote Monitoring and Management): Used by IT professionals to manage client systems remotely but not for user access to shared files and emails.
