Comparative research shows the relative strengths and weaknesses of five TIG vendors and which kinds of security organization will reap the most benefit.
It’s fashionable to say that in the age of cloud and teleworking, the network perimeter is no more. That with applications residing in cloud environments and employees, partners, and contractors logging in to work from just about anywhere, the old notion of a “castle-and-moat” defensive barrier around corporate assets is a thing of the past.
Well, the situation has certainly changed quite a bit, but the success of next-generation firewall (NGFW) vendors shows that there is still a lot of investment in good old edge security, i.e. technology deployed on the real, or increasingly on the theoretical edge of a network to keep bad guys and malicious stuff out.
Now, with estimates to suggest that enterprise IT systems are attacked every 39 seconds, or around 2,500 times per day, it is clear that whatever security measures we have in place to keep out attackers are under considerable pressure. Those will often include a firewall and, particularly, if it is of the aforementioned next-generation variety, it will come with a lot of compute power on board to inspect all incoming traffic in a stateful manner, all the way to the application layer (7 in the OSI model).
