Firewalls
While getting one firewall for the company's Intranet it should be well known that firewalls come in both hardware and software forms, and that even though all firewalls are programmed, they require proper configuration at the time of installation to suit the requirements of the company. While doing so a number of facts have to be taken into consideration.
The firewall vendors may be making tall claims about the success of the product in the world, but the purchaser must keep a number of issues ready before actually obtaining one for the company. The customer must be cautious that firewall security can be highly complex and that just simplicity cannot be a good measure for the performance, and finally that the firewall after installation requires proper configuration.
