Web Application Firewalls (WAF) have become essential to defend businesses, of all sizes, from sophisticated application layer attacks. Why is WAF so important? Because of the many points of integration within the internal and external system, web application is often seen as a gateway to mission critical information. When web application defence is weak, it makes it easy for an attacker to compromise the web application, gaining access to personal information and intellectual property. Protection against Distributed Denial of Service (DDoS) attacks (which is frequently covered by the mainstream media), is one of the key functionalities of the web application firewalls.
According to the Imperva’s Bot Traffic Report, nearly half of all website visitors are bots. 29% are bad bots including impersonators, hackers, thieves and spammers. An alarming 90% of security events are cause by bad bots, making web application defence even more essential for businesses.
