1.5.2.1 SSL Off Load and Acceleration
SSL can place a heavy burden on an application's performance and because of
encryption, can render many optimization measures ineffective. NetScaler has
incorporated high performance SSL acceleration as a core part of its solution,
transparently offloading the CPU-intensive SSL encryption/ decryption from
local web servers and freeing server resources to service other content
requests. All of the benefits of NetScaler's Request Switching technology can
be applied to SSL traffic to ensure the secure delivery of web applications
without degrading end-user performance.
1.5.2.2 Secure Remote Access
NetScaler’s Secure Remote Access capabilities allow enterprises to provide
their employees, partners and customers with instant access to all authorized
applications, files or data from a standard Web browser. By using SSL as the
underlying protocol, it requires no incremental client software and no changes
to servers or LANs.
In addition to providing an internal LDAP directory, the AAA module of this
SSL VPN integrates with other enterprise directories such as RADIUS,
Microsoft Active Directory and other external LDAP servers.
1.5.2.3 Distributed Denial of Service Attack (DDoS) Defense
The NetScaler 9000 Series product line takes network security to a new level
by intelligently stopping malicious attacks before they reach the servers
without affecting network and application performance. The NetScaler 9000
