Best Small Business Firewalls.

Small businesses are the favorite target of cybercriminals. Since they’re busy building companies and chasing the future, they don’t pay much attention to IT security issues.

Many owners even ignore such matters until they are forced to address them.

According to Statista, cyber incidents, including cybercrime, IT outages, and data breaches, were the leading risk for small businesses globally for 2022.

About 40% of respondents cited cybersecurity incidents are their biggest concern.

Security is the most critical issue for small and midsize businesses today. Therefore, SMBs should invest in solutions to enhance their cybersecurity posture.

Also, antivirus programs and firewalls are crucial as they act as the first line of defense to secure networks.

This article will discuss the importance of firewalls for SMBs, and the 6 best small business firewalls in 2022.

Why are Firewalls Important for Small Businesses?

A firewall can be a hardware firewall with specialized software, an application installed on a computer, or a virtualized system deployed in the cloud.

While different types of firewalls have existed since the 90s, they remain a critical element of cybersecurity.

A firewall appliance can protect your business network by proactively blocking unauthorized traffic from entering the network.

Firewalls not only focus on network traffic but also prevent access to dangerous or distracting websites.

Firewalls are extremely important for small businesses.

Small businesses face the same security risks as larger organizations, but often lack the resources and personnel to manage comprehensive security measures.

Firewalls are an essential technology for protecting small businesses from cyber threats, such as malware, phishing scams, and other malicious attacks.

Firewalls can prevent unauthorized access to confidential data and can be used to detect and block suspicious activity while allowing legitimate traffic to pass through.

By investing in a secure firewall solution, small businesses can reduce their risk of data breaches and protect their valuable assets

They provide a variety of benefits, including improved security and productivity, better control over network access, and cost savings.

Small business firewalls allow small offices to monitor and control traffic on their networks, ensuring that only authorized users have access.

Some benefits of small business firewalls also include the following.

●    It helps prevent unauthorized access to the network

●    Blocks inappropriate websites

●    Blocks phishing emails

●    Verifies remote connections

●    Monitors bandwidth usage

●    Provides a Virtual Private Network (VPN)

This helps prevent malicious attacks and reduces the risk of data breaches. By using a firewall, businesses can also save money by reducing the need for additional security measures.

Ultimately, small business firewalls are an important part of any organization’s security strategy.

Types of Firewalls

There are also different kinds of firewalls based on how they work, and each kind can be set up as either software or a physical device. There are five different kinds of firewalls that work in different ways.

1. Packet Filtering Firewalls

The oldest and most basic type of firewall is one that filters packets.

They work at the network layer and compare a data packet’s source IP, destination IP, protocol, source port, and destination port to rules that have already been set up to decide if the packet should be passed or thrown away.

Packet filtering firewalls don’t keep track of the connection they’ve made or the packets that have already been sent through that connection. Instead, they watch each packet on its own.

This makes it hard for these firewalls to protect against threats and attacks that are more advanced.

2. Circuit-Level Gateways

Circuit-level gateways check established Transmission Control Protocol (TCP) connections and keep track of the active sessions.

They work at the session layer. They are similar to firewalls that filter packets in that they only do one check and use few resources.

But they work at a higher level of the OSI model (Open Systems Interconnection). The main thing they do is figure out how safe a connection is.

When an internal device starts a connection with a remote host, circuit-level gateways set up a virtual connection on behalf of the internal device to hide the identity and IP address of the internal user.

Circuit-level gateways are simple, cheap, and barely affect the performance of a network. But because they can’t look inside data packets, they aren’t a complete security solution on their own.

3. Stateful Inspection Firewalls

These firewalls check and keep track of connections that are already set up. They also inspect packets to provide better, more complete security.

Once a connection is made, they make a state table with the source IP, the destination IP, the source port, and the destination port. Instead of using a hard-coded set of rules based on this information, they make their own rules on the fly to allow expected network traffic to come in.

They easily get rid of data packets that don’t belong to an active connection that has been checked.

4. Application-Level Gateways

Application-level gateways, also known as proxy firewalls, are set up at the application layer using a proxy device.

Instead of an outsider going straight to your internal network, the connection is made through the proxy firewall.

The external client makes a request to the proxy firewall. After making sure the request is real, the proxy firewall sends it to one of the internal devices or servers on the client’s behalf.

Or, an internal device could ask to access a webpage, and the proxy device would forward the request while hiding the identity and location of the internal devices and network.

Unlike packet filtering firewalls, proxy firewalls use stateful and deep packet inspection to compare the context and content of data packets to a set of user-defined rules.

5. What is a Next-Generation Firewall?

Next-generation firewalls, also called second-generation firewalls, protect organizations with advanced security features. 

NGFWs have features like deep-packet inspection, intrusion prevention (IPS), advanced malware detection, application control, and by inspecting encrypted traffic, a better overall view of the network. 

They can be used in both public and private cloud environments. They can be found anywhere from the edge of an on-premise network to its internal boundaries.

The goal of next-generation firewalls (NGFWs) is to get around the problems with traditional firewalls mentioned above while also adding some extra security features.

Even though next-generation firewalls have flexible features and architectures, it is their ability to do deep packet inspection, as well as port/protocol and surface-level packet inspection, that makes them truly next-generation.

Gartner says that a next-generation firewall is “a deep-packet inspection firewall that goes beyond port/protocol inspection and blocking to include application-level inspection, intrusion prevention, and bringing intelligence from outside the firewall.”

What is a Cloud firewall?

A cloud firewall is a security product that, like a regular firewall, blocks network traffic that could be harmful. Cloud firewalls are not like traditional firewalls because they are hosted in the cloud

Traditional firewalls create a barrier around an organization’s internal network, and cloud-based firewalls do the same thing for cloud platforms, infrastructure, and applications. Cloud firewalls can also protect infrastructure that is not in the cloud.

Best Firewall for Small Businesses

Firewalls are essential in detecting attacks like Denial of Service (DoS) and Distributed Denial of Service (DDoS) that usually send large volumes of data to exploit available resources within an organization.

Denial of Service is like when someone blocks your way. It means that someone is blocking websites or services from working correctly, so no one can use them.

For example, if someone were to build a wall in front of your house and you couldn’t get in, that would be like Denial of Service.

Distributed Denial of Service is like a really mean prank. It’s when someone sends a lot of messages to a website, computer or phone all at the same time.

It’s like if you had hundreds of friends call your best friend’s phone all at once; it would be hard for them to use their phone.

The same thing happens with websites and computers when they get too many messages at once. It can slow down the website or make it not work very well.
