Routers are necessary because most locations have more than one computer or mobile device accessing the network at the same time - if you just had a stationary desktop, like in the old days, you could plug it into a modem and call it a day. You can think of them like traffic cops navigating a congested intersection: The router’s job is to look at each packet of data, read its source and destination IP addresses, find the destination IP in its routing table and then send each packet on its way in an orderly fashion.

Routers are what your network uses to forward packets of data back and forth between your internet service provider (ISP) and your devices. You’re doubtlessly already familiar with these devices - in fact, you probably have one sitting on a shelf or a table at home. So, what’s the difference between these two devices, why do you need them, and how do they work to prevent hackers from attacking your data and using your network? Let’s dive into the basics of how both pieces of hardware function in your network and how these vital network security products impact cybersecurity and prevent data breaches and attacks. Add a hardware firewall to your network and you’re doubly protected against suspicious activity, malware - even content leaks, in some cases. Your network router, when properly secured, stands as your first line of defense against network infiltration, buffering attackers who want to use your network illegally or gain access to sensitive materials and proprietary documents. Luckily, you’re not helpless in the face of such attacks. But you never had to worry about the kinds of security issues you face today, where criminals mask themselves as legitimate users and hack into your devices, networks and servers. We don’t mean to wax nostalgic here, but remember the old days, when all you needed to connect to the internet was a phone jack, a computer and a dial-up modem? Sure, your internet speed was about 56 kilobits a second - or even less if there was a lot of noise on the line.
