When economic hard times come around, you have to ask yourself if you really need to spend money on new things. One of those things might be your trusty ISA firewall. You might be running ISA 2004 or ISA 2006 and they’ve been working for you fine for all these years.
Why should you upgrade to a TMG firewall when your ISA firewalls are working fine?
