Traditional network filtering technologies are becoming obsolete. As network traffic continues to increase in volume and complexity, malicious content and attacks are evolving at an alarming rate.
In 2011, Microsoft reported that one in every 14 downloads contained malicious content, which could jeopardize operations, reputation and create customer relationship management challenges. According to PwC’s 2012 Global State of Information Security Survey, a mere 43% of security experts are confident in their information security strategy. Malicious content and non-compliant data (which have evolved with the proliferation of mobile data usage, social media and cloud computing) can easily breach a weak network security system. Consequently, organizations will suffer from information leakage and possible IT infrastructure damage.
Standard inspection technologies that secure networks at the packet level, such as packet filtering and deep packet inspection (DPI), are relatively inefficient and unable to provide safe usage of the new Internet. A different approach to network security needs to be taken.
