Why is it important to have a firewall?

Firewalls protect against outside cyber attackers by shielding your computer or network from malicious or unnecessary network traffic. Firewalls can also prevent malicious software from accessing a computer or network via the internet.

A server is engulfed in flames behind a firewall.

A firewall is important for several reasons, particularly in the context of network security and data protection:

  1. Network Security: Firewalls are a barrier between your internal and external networks (like the Internet). They monitor and control incoming and outgoing network traffic based on predetermined security rules. This helps to prevent unauthorised access to your network.
  2. Data Protection: By monitoring traffic, firewalls help to prevent data breaches. They can block malicious traffic, such as hackers or malware, from accessing sensitive data stored on your network.
  3. Traffic Management: Firewalls can be configured to control which types of traffic are allowed to enter or leave the network. This can prevent non-business-related traffic, potentially harmful downloads, or access to unsafe websites.
  4. Preventing Attacks: Firewalls can protect against various types of cyber attacks, such as Denial of Service (DoS) attacks, by filtering out potentially harmful traffic.
  5. Compliance and Regulatory Requirements: In many industries, having a firewall is a part of compliance with regulatory standards. These standards often require companies to protect customer data and ensure the integrity of their information systems.
  6. Remote Access Management: For businesses that offer remote access to their network, firewalls can provide employees with a controlled and secure way to access internal resources from external locations.
  7. Performance Enhancement: By blocking unwanted traffic, firewalls can also improve the performance of your network, ensuring that bandwidth is used efficiently for business-critical applications.

In summary, a firewall is a crucial component of your network security. It helps protect sensitive company data, ensures compliance with regulations, manages network traffic, and guards against cyber threats.

There are many different manufacturers and configurations.

Even if you currently have a firewall, if the unit is not properly configured, it will not fully protect your business. We can assist with upgrades, renewals and troubleshooting.
