What is an SPI Firewall?
Most business owners are aware of the benefits of firewalls to their operation. As a provider of SonicWall firewalls, we are always excited to learn about the new technology on offer and the best ways to improve our digital security. An SPI firewall offers many advantages over other firewalls, but it’s not necessarily going to be something that everyone needs to invest in. Today we’re going to discover what an SPI firewall is, how it works and whether it’s better than the other options on the market. Our team will be here to support you at any time and help you choose the best firewall for your business needs.
What is an SPI Firewall?
Before we can look more at the SonicWall firewall features which make this type of firewall so popular, it’s important to understand what is SPI. SPI is an abbreviation for stateful packet inspection and is a type of firewall that is considered to be context-aware. You might also hear this type of firewall referred to as a smart firewall or dynamic packet filtering. It has a more flexible set of rules when it comes to filtering data packets, working to look at the context of the data packets as they enter the system and check whether they correspond to any of the active connections you have. It also has the ability to recognise patterns and stop attacks from occurring due to these repetitive actions.
An SPI firewall will be able to notice if you are getting many packets from one IP address. It will see that this is abnormal and close off the opened communication ports in order to stop a data breach. As you can see, that’s a huge advantage for business owners of any size, and it’s what sets this type of firewall apart from stateless packet inspection options. It can help to offer an additional layer of protection, and it’s one of the many reasons to upgrade to the latest SonicWall Gen 7 TZ firewall. Of course, this level of protection may not be necessary for some smaller businesses, but SPI firewalls are becoming an option that many small and medium-sized business owners are considering too.
The Benefits of an SPI Firewall
As you can probably already tell, this type of SonicWall firewall offers many benefits over older models that don’t have such advanced technology. SPI firewalls are typically much stronger for companies to use than stateless firewalls. They will be able to examine the content or context of the packets as they come in. This technology is able to spot more threats and anomalies than more basic firewall models. SonicWall TZ firewalls are a great option for business owners of all types and are one of the best options on the market today for anyone investing in their first firewall. Some companies do still prefer to use stateless firewalls as they can be faster and cheaper. However, when it comes to enhancing the security within your business, we always recommend investing in the best equipment and software you can.
How to Install an SPI Firewall
You have a few different options when it comes to buying an SPI firewall for your business or personal use. The first option is to invest in a router with an SPI firewall. Most outers naturally come with a built-in firewall, with most of these today being stateful firewalls. The good thing about using a router is that it won’t just protect one device. Instead, it will protect your whole network and keep every device in your workplace safe.
Firewall software is a good option for anyone who is looking for a quick and easy way to improve their digital security in their workplace. You can install third-party software on any device, but remember that you’ll need to have a subscription for each device you are using. It’s typically very easy and quick to set this up, but you’ll have to pay to renew it annually or on a regular basis. Finally, many antivirus software options now come with an SPI firewall. This can be another simple way to improve your digital security while also offering you antivirus protection as well.
As you can see, an SPI firewall could be a great investment for your business if you are looking to improve your digital security. Our team will be here to support you in finding the best option for your business based on your current needs and security concerns. No matter the shape and size of your company, having firewall protection in place is something everyone needs in this day and age.
