In a cloud-first world, your business is only as strong as your internet connection. But most businesses buy internet based entirely on the wrong metric: advertised download speed.

Speed vs. Reliability

While download speed is important, it means nothing if the connection drops twice a week. Business internet must be underpinned by a Service Level Agreement (SLA). Unlike residential connections, business-grade services like C9 Fibre come with a 99.95% uptime guarantee and prioritised fault restoration.

The Power of Symmetrical Connectivity

Standard broadband provides fast downloads but slow uploads. If your team is uploading large files to the cloud, participating in HD video conferences, or using off-site backups, a slow upload speed will cripple productivity. Symmetrical services (like Business nbn® Enterprise Ethernet) provide matching upload and download speeds.

Business Standard

For teams over 10 people relying on Microsoft 365 or Google Workspace, symmetrical internet is no longer a luxury—it is an operational requirement.

Redundancy & Failover

What happens to your business if a contractor cuts the fibre optic cable outside your building? With an integrated 4G or 5G failover solution, your router automatically switches to the mobile network within seconds. Your phones keep working, your POS systems stay online, and your team keeps working.

Managed Security

Fast internet must be secure internet. A business-grade connection should sit behind a properly configured, next-generation firewall that provides intrusion detection, content filtering, and secure VPN access for your remote workers.
