Preventing Opera browser VPN

A fight against open-access I'm afraid.

Opera Software have published their latest browser boasting built in free VPN giving access past firewalls of countries, companies, education establishments etc.

Free VPN | Now built into Opera browser

As one on the other side of the fence trying to curb access because of users clobbering our public network connection and viewing 'inappropriate content', (i.e. site not work related, but in work and getting paid) including gambling, shopping, online auctions, games, social media, webmail, streaming services and the most popular sites, how can we lock it down? I know that there are tools such as Websense that try to keep up with published VPNs, but we haven't got that installed.

Is there a way to prevent it being enabled on the browser? I've seen before that Internet Explorer can have it's options fixed/greyed out according to company standard.

Obviously there are some business needs to have https access (which I think most VPN options use) to certain sites, but the list is vast.

Personally I'd prefer us not to install software we cannot control, but that seems too draconian, even for me. Installations may be on Windows, MAC, or Unix desktops.

Your suggestions would be much appreciated. I doubt that Opera Software will really want to share this.

Kind regards,
Robin

P.S. I hope you didn't try to click the most popular sites Smilie

GNUNET-VPN(1)						      General Commands Manual						     GNUNET-VPN(1)

NAME

       gnunet-vpn - manually setup a GNUnet VPN tunnel

SYNOPSIS

       gnunet-vpn [options]

DESCRIPTION

       gnunet-vpn  can	be  used  to manually setup a VPN tunnel via the GNUnet network.  There are two main types of tunnels.	Tunnels to an exit
       node which routes the traffic to the global Internet, and tunnels to a node that runs a service only within GNUnet.  Depending on the  type
       of  tunnel, gnunet-vpn takes different options.	The "-i" option is required for tunnels to an exit node, whereas the "-p" and "-s" options
       in conjunction with either "-u" or "-t" are required for tunnels to services.  For exit tunnels, both UDP and TCP  traffic  will  be  redi-
       rected.	For service tunnels, either UDP ("-u") or TCP ("-t") traffic will be redirected.

       The  tool  will	display the IP address for this end of the tunnel.  The address can be displayed as soon as it has been allocated, or only
       after ("-a") the tunnel has been created.

OPTIONS

       -4, --ipv4
	      Desired IP address on this end of the tunnel should be an IPv4 address.

       -6, --ipv6
	      Desired IP address on this end of the tunnel should be an IPv6 address.

       -a, --after-connect
	      Display IP address only after the tunnel is fully connected.

       -c FILENAME,  --config=FILENAME
	      Use the configuration file FILENAME.

       -d SEC, --duration SEC
	      The mapping should be established for SEC seconds.  Default is 5 minutes.

       -h, --help
	      Print short help on options.

       -i IP, --ip IP
	      Tunnel should be to an exit node and connect to the given IPv4 or IPv6 IP address.  Note that you can specify an IPv6 address as the
	      target here, even in combination with "-4" (4to6) and similarly you can specify an IPv4 address in combination with "-6" (6to4).

       -L LOGLEVEL, --loglevel=LOGLEVEL
	      Use LOGLEVEL for logging.  Valid values are DEBUG, INFO, WARNING and ERROR.

       -p PEERID,  --peer=PEERID
	      Name of the peer offering the service to connect to.  Cannot be used in conjunction with "-i", requires "-s".

       -s NAME,  --service=NAME
	      Name of the service running on the target peer.  Cannot be used in conjunction with "-i", requires "-p".

       -t, --tcp
	      Service runs TCP.  Either "-t" or "-u" must be specified when using "-s".

       -u, --udp
	      Service runs UDP.  Either "-t" or "-u" must be specified when using "-s".

       -V, --verbose
	      Be verbose.

       -v, --version
	      Print GNUnet version number.
