“Newer solutions that include user entity and behaviour analytics, image analysis, machine learning, and data-matching techniques are being used to augment existing solutions.”
In addition, Kim said Public cloud adoption will impact firewall spending by less than 10 percent until the end of 2019 but will have an impact after that.
While software as a service (SaaS) adoption is growing, the effect on firewall spending will be limited for the next three years - SaaS is the first choice for only 16 percent of CIOs surveyed by Gartner in 2015.
“Transitions also take time, during which vendors of cloud access security brokers (CASBs) will not only continue to evolve to cover more than just SaaS, but also perform similar roles for infrastructure as a service (IaaS) and platform as a service (PaaS),” Kim added.
In addition, firewall vendors will also have to deal with one of their main challenges for the next few years: decrypting Secure Sockets Layer (SSL) at scale.
“Half of midsize and large organisations will add bigger, more advanced inspection-oriented features to their network firewalls by 2019,” Kim added.
“Bandwidth has been increasing, requiring larger-scale, higher-performing and more expensive firewalls. In addition, organisations are looking to firewalls to consolidate other features, such as web filtering and intrusion prevention capabilities.
“Some are enhancing their firewalls with new content inspection features, such as malware sandboxing.”
