The Internet has become increasingly complex, leaving many enterprises vulnerable to malicious attacks. Organizations are faced with trying to protect their infrastructure against network security attacks, as well as attacks that are specific to the application layer. Every year, security breaches cost companies millions of dollars in revenue, productivity, and lost reputations. Organizations have traditionally responded to these threats by enhancing network security through the use of firewalls. However, this relatively narrow scope has proven insufficient. Although traditional firewalls may protect an organization against network attacks, they are incapable of defending against the new breed of attacks targeting the application layer. Organizations are looking for more dependable, scalable solutions to broaden their security reach and increase their protection levels.
