Firewalls are an essential pillar of any enterprise network security strategy. They sift traffic coming in and going out of corporate networks, offering round-the-clock perimeter protection.
Even better are today’s next-generation firewalls (NGFWs), which bring interoperability and contextualization into the mix. These hybrid firewalls provide a more effective layer of protection as they combine both traditional firewalls with newer types.
Unfortunately, NGFWs and older versions for that matter are not the “be-all and end-all” of enterprise network security. They serve as a good starting point, but they also need to be appropriately configured to work — along with the right data feeds, which can include WHOIS history data, as this post will suggest.
