What Is a Network Firewall and What Are the Benefits?


As business functions, such as accounting, migrate to the cloud and sophisticated cyberattacks increase, businesses demand a threat deterrent that can address these concerns. Network firewalls, such as Cisco-Meraki firewalls, form the first line of defense. These security tools safeguard networks and even devices against cyber threats. Stick around as we dive deeper into network firewalls and learn how they can help your business network be more secure.

What Is a Network Firewall?

Modern businesses are plagued by many cyber threats, from advanced malware to data breaches. Network firewalls (software or hardware) can help enforce policies that block malicious software and cyber criminals from entering a secure network.

This security tool controls traffic flow between a secured private network and the internet. However, it can also be employed throughout a secure private network to mitigate the risk of cyber threats and unauthorized access attempts.

A network firewall examines data flow (inbound and outbound) and checks IP address, content type, and other elements of traffic. Once that’s done, it allows or blocks based on predefined security protocols.

What Are the Benefits of a Network Firewall?

Now that you have a basic understanding of what a network firewall is, here are a few ways this tool can help keep your business safe in this ever-changing digital age.

1.    Traffic Monitoring and Filtering

Data flowing in and out of your network system increases the risks of hacking and data breaches. A firewall addresses this concern by monitoring and filtering incoming and outgoing traffic based on pre-established rules. Businesses that leverage these security tools can manage their network system effectively and prevent potential threats.

2.    Preventing Unauthorized Access

Hackers and malware often exploit hidden entry points on a network to gain access to sensitive data. But a firewall, as your system’s security guard, can identify possible backdoors, preventing attacks from agents who want to steal data. A firewall also ensures that only users authorized to use the networks can communicate within the system or access and modify vital resources.

3.    Malware Protection

Trojans, viruses, worms, ransomware, and other malicious software have become too advanced to be avoided by traditional methods. Firewalls work in tandem with antivirus software to analyze network traffic and identify malicious patterns linked to known threats before they damage the system.

4.    Compliance Adherence

Companies and businesses in regulated sectors must adhere to data protection protocols. Firewalls do a great job ensuring these organizations follow pre-described data security regulations and industry standards.

These network tools protect user data and privacy, maintaining a comprehensive log of people who can access and modify sensitive information. Auditors just need to access this log to ensure the organization adheres to data security measures.

Wrapping Up

Traditional firewalls establish a good foundation for network security. However, modern threats require more advanced solutions. Next-generation firewalls, or NGFWs, offer sophisticated countermeasures in addition to the ones mentioned above, like intrusion detection and prevention (IDS/IPS). But no matter what type of firewall you use, network protection is a critical step towards safeguarding your digital future.
