Connectivity Management Platform

CSL's Connectivity Management Platform (CMP) allows our customers to access data from their M2M estate, making managing their IoT solutions a more efficient experience.

Insights from Analytics

IoT nirvana is getting your connected devices to do a job so that you don't need to, this isn't something that happens instantly though as both people and machines need to learn patterns and behaviours in order to a) make recommendations and b) learn what decisions to make.

Omnichannel Platform Management

Manage your SIM estate on app, mobile and desktop to ensure that the lifecycle of your solutions is available to control on the go.

Stay connected anytime, anywhere

Our device management portals and APIs allow you to integrate, access and control your connections.

Alarm SignallingAlarm Signalling is embedded in CSL’s DNA and has been for over 25 years. We offer industry leading and award-winning solutions to problems experienced at the very forefront of critical security needs. Our range of single and dual-path connected alarm signalling devices and patented roaming technologies ensures we maintain the highest standards in quality and service for our customers and partners.

SIMs We specialise in SIMs and SIM technology. The IoT industry is rife with terminology that is used interchangeably, and often incorrectly. If you're confused about eSIM, MFF2, WLCSL (which are all forms of embedded or integrated SIM cards) we can help. Many IoT devices still use removable 2FF, 3FF and 4FF formats which are the triple cut SIM that you'd typically find in your Smartphone (FF just means Form Factor, or shape/size).

Routers IoT Routers, 4G Routers, LTE Routers... these are all essentially the same thing. There are many different options to suit the use case needed, so please get in touch to discuss your needs. Although all IoT Routers essentially do the same job (provide connectivity with an IoT SIM) they need to be configured correctly e.g. for indoor or outdoor use and/or weak signal.

Broadband CSL can provide specialist broadband, as used by the majority of our Alarm Receiving Centre partners. A combination of secure broadband and IoT technology can help provide a seriously robust connectivity solution. For critical sites that require 100% uptime, broadband service can be backed-up by mobile 4G, via an IoT Router.
