Preventing data leakage

As a best practice, Forcepoint recommends that you lock down your firewall to prevent traffic leakage via different protocols and ports. In particular, Google Chrome can default to the experimental QUIC protocol, which uses UDP on port 443. We recommend that you block UDP traffic on port 443 in order to force traffic over TCP. For more information, see the Knowledge Base article Google QUIC protocol is not supported by the Forcepoint cloud service.
