What is Firewall?

In today's digital age, it's essential to protect our valuable data and networks through ever-evolving solutions like firewalls. This network security system protects private computer networks from being accessed by unauthorized parties. Without it, our systems can be vulnerable to a multitude of cyber threats. Today, we’ll look at the history of firewalls, what they do, and how you can incorporate a firewall into your business's IT security.

A Brief History of Firewall

The concept of firewalls began in the late 1980s when the internet was still in its early stages. The first firewalls created a protective barrier between private computer networks and external networks such as the internet. As the internet grew in popularity, firewalls have evolved into sophisticated tools that examine network traffic and regulate access based on programmed security rules.

Today, firewalls are becoming increasingly intelligent and can detect advanced threats to the network. Advanced firewalls are also capable of blocking unauthorized connections, preventing malicious transmissions, and scanning for malware.

What Does Firewall Do?

Simply put, a firewall is a barrier between your company's network and the rest of the world. This crucial software monitors traffic between your network and the internet, blocking any unauthorized access. Firewalls have evolved with time to not only block access to the network but also to prevent unauthorized data transmission. They also monitor incoming data traffic, as well as outgoing traffic to identify potential threats and prevent data loss.

The Impact on Businesses

The introduction of firewalls has helped many businesses and people protect their sensitive data from hackers and cybercriminals. This modern-day protection is important to safeguard your business’s intellectual property and trade secrets.

Firewalls have also helped prevent the spread of viruses and malware, which would’ve led to data loss or reputational damage. Disclosing private customer information can have catastrophic consequences, leading to financial losses and legal actions.

Lastly, firewalls provide a variety of content-filtering capabilities to a network’s administrators. They allow many organizations to block unwanted or illegal websites and content from their network. A great example would be the ability to block social media websites during a company’s business hours.

How Can a Business Utilize a Firewall?

A company can incorporate a firewall into its systems with an IT professional’s help. There are different types of firewalls, including software and hardware firewalls that are incorporated into a variety of networks. 

But how do you choose the right firewall for your business? There are several factors to consider when selecting a firewall, including the complexity of your network, the size of your organization, the level of traffic, the type of data stored, and your budget. We recommend consulting with an experienced IT team to determine which firewall is best suited for your business. They’ll consider the network, types of traffic, and the security needed to deter a wide array of cyberthreats.
