Industrial Networking & Connectivity Solution Providers in India: 10 Companies to Know

A modern factory can have hundreds or thousands of devices generating data PLCs, robots, drives, sensors, HMIs, cameras and edge computers. The difficult part is not generating that data. It is moving the right data between machines, control systems and enterprise platforms without compromising uptime.

That is driving demand for industrial networking solutions in India. MarketsandMarkets estimates India’s Industrial Networking Solutions market at $931.74 million in 2023, projecting it to reach $2.74 billion by 2028 at a 24.1% CAGR. Its coverage includes wired and wireless connectivity, IIoT, network security, remote monitoring, predictive maintenance and network integration.

Industrial Ethernet is a major part of that expansion. Grand View Research estimates India’s Industrial Ethernet market at $520.2 million in 2023, with revenue projected to reach $1.17 billion by 2030.

But industrial networking is not the same as plugging machines into an office network. Plants need deterministic communication, redundancy, rugged hardware, cybersecurity and support for multiple industrial IoT protocols. PROFINET, EtherNet/IP, EtherCAT, Modbus TCP and OPC UA can all appear within the same industrial environment, often alongside legacy fieldbus systems. Against this backdrop, these are some of the key companies serving India’s industrial connectivity market.

Siemens: A Full Industrial Networking Stack

Siemens is one of the most established names in industrial networking, particularly for factories already built around its automation ecosystem.

Its SCALANCE portfolio covers industrial Ethernet switches, routers, security appliances, industrial WLAN, remote connectivity and industrial 5G. The range extends from compact machine-level switches to high-performance Layer 3 networks for larger manufacturing and infrastructure projects.

Siemens also ties networking closely to PROFINET and its broader automation environment. That makes it relevant when networking, PLCs, drives, HMIs and engineering systems need to work as one architecture rather than as separate layers.

Rockwell Automation: Networking Around EtherNet/IP

Rockwell Automation takes a similar ecosystem-led approach, with its Stratix industrial Ethernet portfolio designed to work closely with Allen-Bradley control systems.

Its Stratix switches support industrial applications including EtherNet/IP, with features such as network prioritisation, broadcast-storm protection, fibre connectivity and extended operating temperatures.

This matters in production environments where network performance directly affects machine control. Rockwell’s managed networking products can also be integrated into its Logix and FactoryTalk environments, giving plant teams a common view of control and network events.

Schneider Electric: Connecting Modicon-Based Automation

Schneider Electric brings networking into its Modicon automation portfolio, with products covering Ethernet infrastructure, gateways, routers and industrial communication.

Its industrial communication portfolio supports technologies including Modbus, CANopen, Ethernet TCP/IP and PROFIBUS, while Modicon Networking is designed to connect Ethernet devices within automation systems.

The company’s approach is particularly relevant to manufacturers modernising existing control architectures. Instead of replacing every legacy machine, gateways and communication infrastructure can help bring older equipment into a more connected network.

That is increasingly important in India’s brownfield factories, where automation systems often come from different generations and vendors.

HMS Networks: The Protocol Bridge for Mixed Industrial Environments

Its Anybus brand connects machines and devices across different industrial networks, while Ewon focuses on secure industrial remote connectivity and IIoT data access. HMS also offers Ixxat products for CAN, industrial Ethernet and functional safety, along with N-Tron industrial networking products.

This becomes valuable when a factory has equipment speaking different protocols. A machine running one industrial Ethernet standard may still need to communicate with a PLC, SCADA platform or cloud application using another.

Moxa: Industrial Networking Built for Harsh Environments

Moxa has built its business around industrial connectivity rather than conventional enterprise networking.

Its portfolio includes industrial Ethernet switches, secure routers, wireless access points, cellular gateways, media converters, network-management software and secure remote access.

The company also focuses heavily on manufacturing connectivity. Its solutions include Modbus gateways, remote I/O, protocol gateways and Ethernet switches designed for industrial environments. Moxa cites network recovery capabilities and OT/IT integration among its manufacturing applications.

That breadth makes it useful when a project needs more than an Ethernet switch,  particularly where serial equipment, legacy protocols, wireless devices and modern Ethernet infrastructure have to coexist.

Phoenix Contact: From Fieldbus to Industrial Ethernet and IIoT

Phoenix Contact covers almost the entire industrial communication chain, from fieldbus connectivity and gateways to Ethernet, wireless networking and cybersecurity.

Its industrial communication portfolio supports PROFINET, OPC UA, PROFIBUS and INTERBUS, alongside industrial Ethernet switches, routers, media converters, wireless systems and serial interfaces.

Its newer networking hardware also moves toward technologies such as Time-Sensitive Networking (TSN), Single Pair Ethernet and Ethernet-APL. Some switches support both PROFINET and CC-Link IE TSN, while Ethernet-APL products target process-industry field devices.

Belden / Hirschmann: Industrial Ethernet for High-Availability Networks

Belden’s Hirschmann brand is strongly associated with industrial Ethernet infrastructure.

The portfolio includes managed and unmanaged switches, cybersecurity products and networking accessories designed for industrial environments.

Hirschmann also supports network architectures built around redundancy and high availability. Technologies such as High-availability Seamless Redundancy (HSR), Parallel Redundancy Protocol (PRP) and Precision Time Protocol (PTP) are part of its industrial networking technology portfolio.

Advantech: Industrial Connectivity Meets Edge Computing

Advantech is particularly relevant where networking and edge computing need to sit together. Its industrial networking portfolio includes managed and unmanaged Ethernet switches, Gigabit switches, PoE, protocol switches, industrial wireless connectivity and SFP modules. Its range also includes EN50155 and IEC 61850-3-certified switches for transportation and power applications.

The wider Advantech portfolio connects networking with industrial computers, edge AI and IoT systems. That makes the company relevant for factories that are not simply building a network but creating an edge architecture around it.

Weidmüller: Networking From the Cabinet to the IIoT Layer

Weidmüller offers industrial Ethernet switches, routers, WLAN, media converters, gateways and remote-access solutions.

Its managed switches support protocols such as PROFINET and EtherNet/IP, while its security-oriented products provide functions including VLAN isolation, authentication and firewall capabilities.

The company is also moving deeper into IIoT connectivity with Single Pair Ethernet, which can extend Ethernet-based communication closer to sensors and field devices.

For factories, this creates a useful bridge between physical connectivity and the data layer. The same network architecture can increasingly support control traffic, diagnostics and IIoT data.

Veryx Technologies: Network Testing and Industrial Observability

India-based Veryx Technologies comes from a different angle: testing, monitoring and observability rather than traditional industrial switches.

Its ATTEST platform provides automated Layer 2 and Layer 3 testing for networking equipment, while its Cloudmon platform provides unified observability across IT, OT and IoT environments.

This becomes relevant as industrial networks grow more complex. Adding switches and protocols is only half the job; manufacturers also need to know whether those networks are performing correctly and where faults are developing.

The Network Is Becoming Part of the Production System

India’s industrial networking market is expanding because factories are becoming more connected, not simply because they need faster Ethernet.

Robots, sensors, drives, vision systems and edge computers are creating more data, while manufacturers want that information available across production, maintenance and enterprise systems. Market research points to strong growth in India’s industrial networking solutions and Industrial Ethernet segments. The challenge is keeping all those systems talking without turning the factory into a patchwork of incompatible networks.

That is why the next phase of India’s industrial connectivity market will be shaped by protocol interoperability, cybersecurity, deterministic networking and edge-to-cloud integration. The winners for manufacturers will not necessarily be the companies selling the most switches. They will be the providers that can make the entire industrial network work as one system.
