Blue Coat: How to Gain Visibility and Control of Encrypted SSL Web Sessions :
Because a proxy is an active device (i.e., it terminates traffic), it
acts as both the server to the client, and the client to the server.
Thus, it has a native understanding of both the user and the
application. For many organizations, users will only connect to the
Internet via a proxy – because of the control it affords an
enterprise. Because a proxy terminates connections, it offers a
critically important control point for policy, performance, and
protection of all Web-enabled user and application interactions.
Blue Coat SG is the leading secure proxy appliance, offering
enterprises “the power of the proxy” in a broad range of sizes. Blue
Coat extends that leadership by offering SSL proxy functionality on
its market-leading proxy appliance.
Whereas takes an other approach -decryption: ( Giamon: SSL Decryption: Uncovering The New Infrastructure
The offloading of SSL decryption also eliminates the need to have
multiple decryption licenses for multiple tools. After all, a
security appliance with integrated SSL decryption, for example, does
not benefit other tools, such as application performance monitoring.
Gigamon can supply decrypted traffic to multiple tools
simultaneously, maximizing the overall efficiency, security, and
performance of the infrastructure. An associated benefit of this
approach is that the private keys can now be securely uploaded to
just the visibility infrastructure instead of sharing it with
It also delivers to IT and security administrators the
right level of visibility into traffic, including SSL-encrypted
segments that are at the heart of today’s cloud infrastructures.
GigaSMART decrypts the packets and sends the traffic to multiple
out-of-band tools, including intrusion detection (IDS), data loss
prevention, and application performance monitoring for analysis.
