Cyber threats are now a “clear and present danger” to most organizations, companies and governments of the world. A good cyber defense involves many, intricate layers. You can never have enough layers, just like you can never remove all the risk. In order for organizations to reduce as much risk as possible, in a rapidly shifting threat landscape, they must constantly make improvements. The threat groups are making rapid improvements and increasing their expertise at a steady rate. They are investing  in R&D and Zero-Day exploits. To offer a good defense, we must make progress at the same rate as the threat groups or we may fall behind, increasing risks and allowing the cyber world to become like the “wild-wild west.”
