Re: Firewalls acting as access controllers

[Ramesh Krishnan <csramesh () gmail com>]

you probably need a software which can restrict the employee access to
the internet.

i have tried this and it worked out with PIX firewall and the content
filgtering tool "websense"(http://www.websense.com).if you want, you
can integrate this with active directory and provide user based access
also.
