Firewall approval is not required. Device manufacturers, suppliers, service personnel or their customers receive secure remote access to connected devices. The solution is not a cloud solution, it is operating system and hardware-independent and supports mobile iOS and Android clients. It is also scalable: up to 4000 simultaneous connections are possible.
