A firewall is a network security system, either hardware- or software-based, that controls incoming and outgoing network traffic based on a set of rules. Acting as a barrier between a trusted network and other untrusted networks — such as the Internet — or less-trusted networks — such as a retail merchant’s network outside of a cardholder data environment – a firewall controls access to the resources of a network through a positive control model. This means that the only traffic allowed onto the network defined in the firewall policy is; all other traffic is denied.
TechNavio’s analysts forecast the Global Enterprise Firewall market to grow at a CAGR of 7.74% over the period 2014-2019
Gartner says that was growing 9.5% in 2014, to $9.5B and it will grow 10% in 2015 to $10.5B
Marketsandmarkets mentions that the enterprise firewall market is expected to grow from $6.14 billion in 2014 to $8.41billion by 2019, at an estimated Compound Annual Growth Rate (CAGR) of 6.49% from 2014 to 2019.
As you can see there are some deviations from one report to another but we can safely say that this market is really huge and is growing quite fast.
The rise in the demand for SaaS-based security solutions is one of the major trends witnessed in the market. Also, the rise in network security threats is one of the major factors fostering the growth of the market. Increased dependence on websites and web applications has led to an unprecedented rise in cyber-attacks, thereby leading to an increase in advanced persistent threats.
