When discussing business-class networking hardware, the nomenclature tends to get convoluted.

Routers, Switches & Firewalls: What Are the Differences?

Aug 12, Blog. Each kind of device has advantages and disadvantages over the others, and each have different purposes. In this blog post, we will identify the key uses for each device and explain why you typically need all three devices in a single network! A local router sometimes called a Gateway is the first device in your network that gives you internet connectivity. It sits between your Internet Service Provider ISP and determines which network traffic should be passed through to the ISP internet versus which traffic should remain in your network.

Routers are the backbone of the internet. You could not browse the web or communicate via email without them. There are even huge routers that process hundreds or thousands of gigabits of traffic per day that ISPs manage, and which enable ISPs to be able to pass massive amounts of information back and forth.

Billy and Jane work in an office and use a server to back up all of their files. They also use the internet. Whenever they browse the internet, Billy and Jane are identified to the outside world by this IP public address. However, their private IP addresses are completely different. The server would have an IP address of The router The ISP which has a different unique IP address then routes the request to another router, which gets passed to yet another router.

They help computers and other network devices communicate with each other. Building upon the example in which Billy and Jane live, the switch would be directly connected to the router, but each internal network device would be connected to the switch. In this scenario, if Billy were to backup data from his computer Unlike routers and switches, firewalls are network security appliances.

There are two types of hardware firewalls: perimeter firewalls and internal firewalls. Most smaller networks typically have just perimeter hardware firewalls, which control access and secure local networks from the outside world. For this reason, most perimeter firewalls also have routing capabilities although that is not a requirement. While routers without firewall capabilities blindly pass traffic between two separate networks, firewalls actually monitor the traffic and helps block unauthorized traffic coming from the outside trying to get into your network.

Some firewalls even have anti-virus and anti-spam mechanisms to protect your network from viruses and unwanted email! In addition to hardware firewalls, there are programs you can install onto your computer or server that acts as a software firewall, such as several software anti-virus products.

Microsoft has even included a Windows Firewall which comes with Microsoft Windows. These programs have limitations and are typically not as sophisticated as a hardware firewall and have several disadvantages.

However, they are a great first step. In summary , routers, switches and firewalls are three unique types of network devices that serve different functions. Some appliances can be purchased which have two or even all three of these features, but typically, it is best to purchase each device separately, especially as a network grows and becomes more complicated.

The Differences Between Routers and Firewalls in Network Security

Router : A router is known as the connecting devices in networking. It is used to select the shortest route for a packet to achieve its target. Like firewall, it also works on the network layer but it also works on physical layer, and data link layer of the OSI Open Systems Interconnection model. Unlike firewall, it does not include encryption before routing the networks. A router does not protect the network from the threats but it include the sharing provision to share internet connection between the networks.

Firewalls, both hardware and software, protect computers from hackers and other online threats by blocking dangerous pieces of data from reaching the system. While hardware firewalls offer network-wide protection from external threats, software firewalls installed on individual computers can more closely inspect data, and can block specific programs from even sending data to the Internet. On networks with high security concerns, combining both kinds of firewalls provides a more complete safety net. A hardware firewall sits between your local network of computers and the Internet. The firewall will inspect all the data that comes in from the Internet, passing along the safe data packets while blocking the potentially dangerous packets. In order to properly protect a network without hindering performance, hardware firewalls require expert setup, and so may not be a feasible solution for companies without a dedicated IT department.


Like router, it also works on network layer of the OSI model. Unlike router, a firewall uses encryption to encrypt the data before transmission. A.


Difference Between Router and Firewall

Router vs. A router is a device in a computer that moves data back and forth between networks. In essence, whenever information is sent along, and between networks, or between locations on one network, a router does the work of directing this data to its rightful location. Forwarding tables also play a key role in the way a router functions.

Firewall and Router are the two most commonly used networking device where one is used for securing the network and other is used for connecting different networks. Now, here is a big question, why we use firewall instead of a router. The firewall is a secured wall between public and the private network. It protects your internal network from the user of the external network. The firewall may consist of hardware or software or both.

A router and firewall are two different things, and the router is hardware to provide connections to various devices. As against, a firewall resides between the network and the system to filter the data going in and out of the system. However, both can be used for filtering the traffic with an access control list. The router works on a hardware level, mostly. In contrast, the firewall is based on software.

The Difference Between a Hardware Firewall and a Software Firewall

One of the major challenges that companies face when trying to secure their sensitive data is finding the right tools for the job. Even for a common tool such as a firewall sometimes called a network firewall , many businesses might not have a clear idea of how to find the right firewall or firewalls for their needs, how to configure those firewalls, or why such firewalls might be necessary. A firewall is a type of cybersecurity tool that is used to filter traffic on a network. Firewalls can be used to separate network nodes from external traffic sources, internal traffic sources, or even specific applications. Firewalls can be software, hardware, or cloud-based, with each type of firewall having its own unique pros and cons.
