Company Profile

Netshield (Pty) Ltd is a Pretoria-based company that specialises in electronic, mechanical, instrumentation, optical and technological research, development and manufacturing. It has 20 years experience in IoT through products that connects any device with an on/off switch to the Internet (and/or to each other) or remote computer dashboard. Information on anything can be gathered through a strategically placed sensor to a gateway so that it can be monitored and controlled remotely through a dashboard.  Netshield thrives on opportunities to create innovative real world products and tailor-made solutions that are based on our clients’ own ideas and are specifically suited for the African and South African markets.

Established in 1994, Netshield with its detailed knowledge of the nature of local and international markets, has produced a range of products, instruments and services that are not just a collection of technical components, processes and features but are highly qualified and designed to satisfy a customer’s specific needs. We achieve this by supplying new, innovative products, solutions, instruments and services through our own global network of specialty resellers and strategic partners.

Through many years of quality service, Netshield has established a distribution and specialty reseller channel to the end user market for our products, instruments, designs and services in South Africa as well as further afield in the rest of Africa and more recently a global market place.

The wealth of the company lies not only in the intellectual property rights of its designed product, software and instrument and services; but also in its highly skilled and valued group of employees. All employees of Netshield SA are focused towards the same goal: Giving their best performance for complete customer satisfaction.

Netshield has a policy whereby we strive to continually evaluate and harness industry standards, industry changes, design challenges, including the application of modular standardisation and modularity in design, in order to simplify the development process and concepts within our own business. This ultimately results in competitive pricing, maintainability, serviceability and backup spares availability that benefits customers.

Core Business Areas and Services
Netshield specialises in creating products and solutions inspired by our client’s challenges. The process starts with an evaluation of the challenge facing the customer, we will then create specifications and develop a product or solutions that will solve the client’s unique challenge or need.

Through many years of product development we have collected and developed a huge variety of reuseable hardware and software elements, all of which are today used in new developments that significantly reduce the development cycle. These elements include a variety of embedded processor modules, IO modules, communication protocols, control elements, database applications, Web and user interfaces.

These elements form the building blocks of most products used in the world today and because we own the intellectual property rights to them, we use them as the basis of most of the products we design. Whats more, our experience in embedded Linux and other operating systems, allows for simple structured expansion on these software platforms through a global programmer network.
