FireMon is proud to present its 2nd Annual State of the Firewall Report based on a November 2015 survey of 600 IT security practitioners, representing a range of professional roles, organization sizes and industry verticals. Survey participants were asked 21 questions about their current firewall infrastructure and management challenges as well as questions about adoption and impact of emerging technologies such as NGFW, SDN and cloud. When compared with results from the 2015 study, the responses revealed three trends that this report will explore further: 1) Firewalls remain an extremely valuable part of the network security infrastructure; 2) Next-generation firewalls continue to see broad adoption, adding complexity to security management; and 3) Awareness around SDN and its impact on network security has increased.
