Why choose CSL Broadband?
- Private Network for Enhanced Security
CSL Broadband runs on a segregated, closed network — not the public internet. This significantly reduces the risk of cyber threats and ensures compliance for applications like alarm signalling, fire systems, and connected healthcare devices.
- Fully Managed Broadband Solution
From router configuration to network monitoring, CSL Broadband is a complete, fully managed broadband service. There’s no need for in-house networking expertise — we take care of it all.
- Plug-and-Play Installation
Our pre-configured hardware with a static IP enables fast, plug-and-play installation, reducing time on site. It’s ideal for remote locations, temporary setups, or where traditional fixed lines aren’t available or take too long to install.
- Reliable Performance, Always-On
CSL Broadband delivers uncontended bandwidth and guaranteed uptime, even at peak times. This makes it the preferred choice for life-critical, compliance-based, and high-security environments.
- Installer-Friendly Broadband
With pre-tested kits, a static IP as standard, and UK-based technical support, CSL Broadband is trusted by installers across multiple industries. It’s broadband that’s built to work — and easy to deploy.

Ensuring private broadband across diverse applications
Retail
Processing payments and managing sensitive customer information demands a cyber-secure broadband connection, as the public internet falls short. CSL Broadband is trusted by retailers to safeguard against cyber-attacks, protecting both their reputation and their organization.
Utilities
Critical National Infrastructure is a prime target for malicious attacks, making it essential to move all data processes off the public internet. Water and energy companies rely on CSL Broadband to secure their operations and ensure uninterrupted service to the nations they support.
Fire & Security
Many applications, including intruder alarms and CCTV systems, rely on local Wi-Fi networks, which can be vulnerable to interference and cyberattacks. Businesses are turning to CSL Broadband to match the enhanced security of mobile connectivity for their IP installations, ensuring robust and reliable protection.
