filtering

My company runs filters on contents available for browsing and I have to check if everyone is respecting the browsing policies. Recently I have spotted some users activate OpenVPN on their workstations and i have discovered that they connect on port 443 of an external server and then use a proxy to circumvent the company filters. Is there any method to monitor VPN connections on allowed ports or to avoid the connections?
