What does the Next Generation Firewall actually do? Get all the details on how it protects your business from cyber threats.
Traditional Firewall vs. Next Generation Firewall
A traditional firewall is able to control the traffic at the point of entry or exit within the network. In other words, it’s the drawbridge between your own business and the ‘great unwashed’ of the rest of the internet.
This was perfect for those simple times – back when you used to be able to see everything that was latching onto your network. Now, businesses are increasingly playing host to a myriad of unknown devices, and a deep dark sea of cloud applications which are downloaded by employees.
The main difference with a next generation firewall is that you can set application controls and policies. For example, if a member of your staff downloads some file sharing software that may be unsecure, this will be automatically be made visible and you can do something about it instantly. Plus, overall you will gain far more visibility and control over the users, devices, threats, and vulnerabilities in your network. So when your board asks you, “Are we secure?” you can provide a much more comprehensive answer than if you have a traditional firewall that only controls traffic.
While still motivated by profit, a new strategy–destruction of service–is emerging, with the IoT and systems with security weaknesses ripe for exploitation.
