Perfectly Secure, Extremely High-Speed, Easy to
Set up, Rock-solidly Stable – Network Operations

Perfectly secure network environment through Bluetooth communication between across Server & Clients

  • across Server and Clients register each other in whitelist and then other computers not listed in whitelist are not allowed to connect; No need to use Firewall S/W to secure connections
  • All network data is encrypted by TLS
  • Dynamic generation of TLS certificates rather than static one
  • Automatically configures Windows Firewall with the most secure settings
  • uses only one user configurable TCP port; The default port number is random
  • Automatically detects changes of network environment and set up accordingly network connections through Bluetooth
  • supports IPv4 & IPv6; across IPv6 only uses link-local address which is not routable. It means across IPv6 network traffic cannot be routed outside your local network and therefore much secure.
  • High-speed network communication implemented by modern network programming

Just copy and paste file/data between computers

  • across has its own blazing fast fileserver enables you to share folders with partner computers. You do not need any other settings or apps such as SMB for file-sharing.
  • User shared folders configured in across are automatically & natively mapped (mounted) as a network drive (volume) in File-Explorer/Finder/ File-app of a partner computer; You can browse shared folders by opening the mapped (mounted) drive (volume) in there.
  • Just copy files/folders in shared folders in one computer and then paste them wherever you want in other computers, or simply drag-and-drop them.
  • Direct file/data copy by peer-to-peer connection is much faster than via an intermediate Cloud server (OneDrive/iCloud/Google Drive).
