Intel® Packet Protect User’s Guide

agement Adapter can perform hardware offloading. If you have other Intel PRO/
100 Adapters in Packet Protect computers, you won’t be able to offload any pro-
cessing, thus increasing CPU utilization and potentially slowing that computer’s
network performance.
Other security options are considered “costly” as well. Perfect Forward Secrecy
is very secure, but if used widely throughout the network, there can be a signifi-
cant effect on servers that have a lot of secure traffic.
Conclusion
Hopefully, this section provided some guidelines for you to consider as you
develop your deployment model. There are no hard-and-fast rules that you must
follow. However, Intel recommends that you begin your use of IPSec and Packet
Protect slowly in your enterprise. You should consider starting with a small
group that use the same pre-shared key and default System Policy. When you’ve
had a chance to evaluate this first implementation phase, you can then decide
how to expand your use of Packet Protect.
