Do I Need More Than a Firewall?
Yes, always, without a doubt, you need more than a firewall. You will need tools to help you harden your system, to check the integrity of your files, binaries and drivers, intrusion detection and prevention tools, patch management technologies, and penetration testing tools. Sometimes you might even need military grade cryptography, security policies to describe what users can and cannot do, training for those users, and above all else, a certification program and even a risk management plan. A firewall is never enough by itself.
