Business Firewalls- Types and It helps Improving Network Security

Most internet users need a firewall, and that’s especially true for entrepreneurs. There are two reasons why a business needs a firewall. The first is that a firewall’s primary role is to protect the internal network of the computer system. More specifically, firewalls’ security prevents outside actors from accessing your computers. The other is that they allow multiple computers to use the same external internet connection or IP address.

The software you can buy or build into the system is generally enough to keep your files safe for personal or private computers. However, software firewalls are not as robust as hardware or next-generation firewall options. Business firewalls provide the essential tools to protect your office and, if you use a cloud firewall, it protects your cloud software.

What Is Business Firewalls

A firewall is a system that is designed to protect a computer or network from unauthorized access. Firewalls can be hardware-based, software-based, or a combination of both. They are used to prevent unauthorized access to data, files, or resources on a computer or network.

Businesses use firewalls to protect their computer networks from unauthorized access and to protect their customers’ information. Firewalls are an important part of an organization’s security infrastructure and should be part of any business’s overall security plan.

Types of Firewalls That businesses can use:

There are  many different types of firewalls that businesses can use which include:

  • Stateful packet inspection firewalls: These firewalls inspect all incoming and outgoing packets and determine whether they are legitimate. Packets that do not match up with the pre-determined firewall ruleset are automatically blocked.
  • Application-level gateways: These firewalls allow or block traffic based on information in higher-level data packets, such as URLs and e-mail messages.
  • Circuit level gateway: A circuit-level gateway uses a three-way handshake to validate whether a connection request originating outside the network is allowed.
  • Proxy servers: Proxy servers enable organizations to control traffic flows in and out of their networks by acting as intermediaries between internal, private networks and external public networks. The proxy server routes data into or out of one network based on rules set up by an organization’s security policy.
  • Personal firewalls: These are software applications that you install on your individual computer or smartphone to protect it from intrusions and attacks when connecting with other computers in a network environment.

Ways Business Firewalls Helps Improving Your Business Network

Business firewalls can keep your employees and customers safe from viruses, malware, spyware, ransomware, and other attacks.

1- Security

You need a firewall to segregate your working networks from where you conduct business from the rest of the internet. You need to segregate your work from the rest of the world to protect your intellectual property, finances, and other sensitive data from bad actors. Many different firewalls help you reach this end goal, just as many manufacturers all lead to the same end outcome.

The best way to determine the best product for your business is to examine the level of granularity and control that your IT team needs to ensure appropriate security. A larger-scale company or enterprise would be best served by an enterprise-grade firewall that’s locally managed and provides a finer grain control of security. Alternatively, a small company, such as a mom-and-pop shop, may be better served by a cloud-managed one-size-fits-all approach.

2- Internal Security

Firewalls can also provide internal security and improve staff productivity by blocking outbound communications to unapproved sites. 

Apart from restricting unauthorized users from accessing your business network, you can also prevent your users from accessing certain sites. Firewalls can be utilized for blocking social networking platforms and major piracy websites, which can be huge time sinks. After all, no organization wants distracted or unproductive employees.

Some well-known sites include gambling, streaming, or social media sites, but you could configure your firewall to prevent your employees from job hunting while using your network. Internal security benefits from ensuring your staff stay on task and prevents users from incidentally allowing malicious activity into your network.

3- Meter Bandwidth

As previously mentioned, certain websites can impact your employees’ productivity. But such careless browsing also takes up valuable bandwidth.

Fortunately, the scope of firewalls extends beyond security. It can also be implemented to meter and limit the network bandwidth. This allows you to reserve bandwidth for significant business traffic instead of wasteful activities like watching videos, photos, or any content unrelated to business. 

4- Enhance Collaboration with VPN

Virtual Private Network (VPN) allows remote users to easily and securely access your internal network. And such connectivity can be established with the help of firewalls. This facilitates collaboration and productivity. 

5- Cloud Computing

In the age of cloud services, the firewall requirement doesn’t disappear. Even if you only have a website or a blog, a firewall is essential for your digital business planning. In some cases, this is provided by your hosting web service. Still, depending on what they’re providing or what services you’re offering, you may elect to install an upgraded security option. Specifically, you should look into dedicated cloud firewall services. This holds especially true for any business offering a cloud product.

Cloud firewalls are unique in that they protect a virtual server for you as the user. They prevent bad actors from breaking into the back end of your system and then taking over admin rights. Researching and utilizing cloud firewalls is a cost-effective option for many business owners just starting.

6- Firewalls Aren’t Outdated

With all-new security options consistently becoming available to business owners and IT professionals, some key security methods are still the gold standard. The firewall is constantly being improved, but it’s unlikely to be replaced as IT professionals and system admins rely heavily on them. As you’re building or improving your security and network plans, be sure to take the time to research appropriate business firewalls. You’re going to need them.

The Bottom Line

In the current digital world, you cannot afford to neglect the paramount importance of a robust firewall for your business. A strong firewall plays a crucial role in protecting your business assets and data. That being said, firewalls are a part of a broader cybersecurity strategy. It would be best to consult an IT company about developing a suitable cybersecurity plan.
