No. You can start with a virtual server and install owncloud on a Linux/*BSD operating system (with Apache/PHP/MariaDB). For a few test a virtual machine is sufficient, if you want to deploy it for more users, you probably should look for suitable hardware, manage backups, ...
You have the owncloud client which syncs a folder on your local file system to the server. That's one way, you can also directly use a network drive or only use ownCloud via web-interface.
If you ownCloud is connected to the internet, that should be possible.
ownCloud itself only features a file firewall in the enterprise version (https://owncloud.com/standard-or-enterprise/) which can limit access to certain ip ranges, times, ... you can however implement restrictions on the webserver or network level (blocking certain ip ranges, limit number of connections, ...). Or you can hide ownCloud behind a VPN (so people outside your company network have first to connect to your company's VPN).
Gather some experience with webservers in general and owncloud in particular, first only for testing in a local network, before putting anything serious on publicly available.
