What is Firewall?
A Firewall is a security device or software that monitors and controls incoming and outgoing network traffic based on predetermined rules. It acts as a barrier between your internal network and the internet.
Why Firewall matters for Australian businesses
Your network infrastructure is the foundation of your entire IT environment. Poorly designed or outdated infrastructure leads to slow performance, security vulnerabilities, and costly downtime. As businesses adopt hybrid work, cloud services, and IoT devices, a modern, well-managed network is more important than ever.
For small and medium businesses in particular, firewall plays a key role in maintaining a secure, efficient, and resilient IT environment. Whether you are reviewing your current setup or planning improvements, understanding firewall will help you have more informed conversations with your IT provider and make better decisions for your business.
