Blue Coat ProxySGs are the industry’s only solutions designed speciﬁcally for securing, accelerating and scaling SSL trafﬁc to

internal as well as external sites over your LAN and WAN. Three solutions are discussed:

Secured and Accelerated Outbound SSL Trafﬁc – Forward Prox>- y

WAN Optimization – MACH5 SSL Prox>- y

Web Server Acceleration – HTTPS Reverse Prox>- y

Secured and Accelerated Outbound SSL Trafﬁc – Forward Proxy

Many organizations today have a need to protect their users and their corporate assets. An SSL forward proxy can help

an organization protect their end-users from downloading and installing threats from the Internet, as well as help protect

corporate assets by preventing conﬁdential and proprietary information from making its way to the Internet (data loss

prevention). Figure 6, below, illustrates the Blue Coat ProxySG SSL forward proxy solution.

HTTPS trafﬁc:

Validate server certiﬁcates, including CA checking and revocation checks using Certiﬁcate Revocation Lists (CRLs).>-

Check and optionally enforce various SSL parameters such as cipher and version.>-

Log useful information about the HTTPS connection.>-

URL ﬁlter based on the server certiﬁcate hostname.>-
