Firewalls are something that any business needs to invest in, but you’ll find that you need to select the right one for your requirements. When comparing firewalls, you’ll see the terms of stateful firewall vs stateless firewall discussed. With so many cyber threats to be aware of, you’ll need to do everything you can to secure your business. Keep reading to find out what the difference is between a stateless and stateful firewall, so you can choose the right firewall for your business.
What is a Stateful Firewall?
There are various types of firewalls on offer, so it’s important to note that not every firewall has the same firewall advantages and features. You need to make sure you choose a firewall based on what is right for your company’s needs. A stateful firewall is one that inspects anything inside the data packages, including the data’s characteristics and communication channels. They will filter out any suspicious data, but they can also track the data behaviours and the patterns of the firewall.
When something suspicious does appear, a stateful inspection firewall will recognise this threat and then address it. You’ll find that a stateful firewall could be used at the edge of your network or within it. An internal segmentation firewall is a kind of stateful firewall, and it can help protect a part of your network if a malicious program gets inside.When something suspicious does appear, a stateful inspection firewall will recognise this threat and then address it.

What is a Stateless Firewall?
On the other hand, a stateless firewall uses the destination and source of the data to find out if it is a threat to your system. You will need to enter these requirements as an administrator, but some manufacturers do set these rules in place before you buy a stateless firewall. When something goes outside the parameters that are set, this is then identified as a threat. The firewall will then block or stop this data from entering, helping to protect your system.
What are the Pros and Cons of a Stateful Firewall?

A stateful firewall helps to detect when data is used to try and get into your system. A SonicWall firewall will protect businesses of all sizes, so even when hackers try to get into your system, you can keep your business going. Stateful firewalls have the ability to log information about network connections, and they don’t need too many ports to communicate properly. You’ll also find that they log the attacks and their behaviours. This information can then be used in the future to stop future attacks. It will learn as it goes, which can help to keep up to date with current concerns.
As with any product, there are some drawbacks to a stateful firewall. It will need to always be kept up to date with the current software updates, or you will find that it could be compromised. You’ll find that some of these firewalls are still susceptible to attacks, and this can result in harm to the network. Finally, they are more open to man-in-the-middle attacks, which are something no company can afford to be the victim of.
What are the Pros and Cons of a Stateless Firewall?
Stateless firewalls are often considered to be less of an intelligent solution for larger businesses. While a stateless firewall is a good option for a sole user, you’ll find that big businesses will usually not opt for this option. This is because a stateful firewall is a more intelligent solution, as it can check future data and learn from past actions. Stateless firewalls need more attention to make sure they are configured properly. While you will have full control over what comes in and out of the system, you’ll need to ensure that you set this correctly. If the manufacturer has made these parameters, you’ll find that they might not be the perfect fit for your needs.
