The digital transformation landscape continues to evolve, and two players stand out in the sphere of cellular connectivity and industrial IoT: Digi International and HMS Networks. Both companies offer robust solutions but cater to slightly different segments and use cases. Whether you’re a business developer, systems integrator, or manufacturer exploring IoT options, understanding the strengths and weaknesses of these two companies is crucial for choosing the right partner.
Company Overviews
Digi International is a US-based company that specializes in mission-critical and industrial-grade connectivity solutions. Founded in 1985 in Minnesota, Digi focuses primarily on cellular routers, embedded systems, and edge computing, catering to verticals such as transportation, energy, healthcare, agriculture, and smart cities. Their cellular product lines are especially well-regarded for their security, scalability, and flexibility in deployment.
Meanwhile, HMS Networks is headquartered in Halmstad, Sweden, and has been active since 1988. The company focuses heavily on enabling industrial equipment to communicate. Their core offerings include network interfaces for equipment, connectivity hardware, and cloud-based data services. HMS’s flagship brands include Anybus, eWON, IXXAT, and Intesis, each tailored to specific communication needs in automation and industry.
Despite both companies operating in the Internet of Things (IoT) space, their strengths lie in different specializations. Here’s a deeper comparison to help unpack their differences and advantages.
Connectivity and Networking Solutions
Digi International:
Digi’s networking hardware focuses on cellular technologies like LTE, LTE-M, NB-IoT, and 5G routing. Popular products like the Digi EX and TX series provide reliable cellular routing, VPN options, and enterprise management systems like Digi Remote Manager. These products are especially useful for remote industrial operations where wired connections are impractical.
Key Advantages:
- Built-in cybersecurity features like Digi TrustFence.
- Cloud-based management through Digi Remote Manager — real-time system monitoring, firmware updates, and geofencing.
- Cost-effective solutions for mid-sized to large industrial deployments.
HMS Networks:
HMS shines in device-level communication across factory floors. Their Anybus gateways and eWON remote access solutions provide flexible bridging between industrial protocols — allowing devices running different standards like Modbus, CAN, or PROFINET to work together seamlessly.
Key Advantages:
- Protocol conversion expertise — HMS handles over 300 communication formats.
- Manufacturing automation support with real-time diagnostics.
- Plug-and-play integration into legacy or hybrid industrial environments.
In summary, if you’re deploying a large number of devices requiring stable Internet access over cellular networks, Digi excels. If you’re integrating machinery and controls in a factory setting with different protocols, HMS is your go-to.
Cloud Services and Software Integration
Digi International:
The engine behind Digi’s smart device management is Digi Remote Manager (DRM). It provides real-time diagnostics, automation workflows, API access, and AI-driven alerts. It’s especially suited for businesses scaling operations across multiple regions.
Pros:
- Cloud portal tailored for scalability and global deployment.
- Advanced security policies with audit logs and certificate management.
- REST APIs for third-party integrations.
Cons:
- Subscription-based pricing can increase operational costs over time.
- Interface complexity for non-technical users.
HMS Networks:
HMS uses Talk2M in its eWON line, offering secure, remote access via VPN to industrial assets. Designed specifically for engineers and service teams, it reduces the need for site visits and improves uptime.
Pros:
- Secure SSL-based VPN tunnels for encrypted communications.
- Mobile-friendly access for field technicians.
- Easy-to-setup dashboards and analytics with M2Web and DataMailbox.
Cons:
- Less powerful API ecosystem compared to Digi.
- Focused more on remote troubleshooting than active device management.
Table: Cloud Service Comparison
| Feature | Digi Remote Manager | HMS Talk2M |
|---|---|---|
| Real-time Monitoring | Yes | Yes |
| Device Configuration | Full Control | Limited |
| Custom Alerts | AI-driven event triggers | Email/cloud-triggered alerts |
| Integration APIs | REST, JSON, IoT Core | CSV/HTTP uploads with DataMailbox |
Target Markets & Use Cases
Digi International:
Digi supports industries requiring cellular connectivity such as:
- Transportation: Fleet routing, onboard Wi-Fi, and asset management
- Smart Cities: Streetlight control, environmental sensors, and surveillance
- Agriculture: Field sensor monitoring and smart irrigation
- Energy: Remote asset control and grid monitoring
Example Use Case:
A logistics firm uses Digi TX64 to provide real-time GPS tracking and telemetry for their delivery trucks. Together with Digi Remote Manager, they can geofence-drop deliveries and troubleshoot units in the field without downtime.
HMS Networks:
HMS targets heavily industrialized environments:
- Automotive Manufacturing: Robot controller interfaces and PLC communication
- Food Processing: Industrial refrigeration automation and error logging
- Oil & Gas: Remote monitoring of pumps and meters
- Building Automation: HVAC and lighting control systems via Intesis
Example Use Case:
A bottling factory integrates HMS’s Anybus Communicator to connect legacy PLCs with a modern SCADA system, enabling predictive maintenance without replacing old hardware.
Global Reach and Ecosystem
Digi International:
Digi products are available through distributors in over 150 countries. They work closely with telco providers and offer certified hardware for various regions. Their solution ecosystem supports AWS, Azure, and Google Cloud, appealing to global developers and enterprise clients.
HMS Networks:
HMS has a robust presence in Europe and Asia with more than 30 sales and support offices globally. Their products are heavily integrated into OEM systems and widely adopted in industrial hubs across Germany, Sweden, and China.
Scalability and Deployment
Scalability:
Digi wins when you’re talking scale. Their infrastructure and fleet management tools are designed for thousands of devices managed via a single pane of glass. For instance, their hardware in public transit systems can manage hundreds of buses seamlessly.
HMS Strength:
While not built for managing massive fleets, HMS is ideal for deployments where different machines and PLCs need to connect in confined or localized environments. Their strategy is based on interoperability over scale.
Security Features
Digi International:
Digi uses TrustFence®, their proprietary security framework. It includes secure boot, certificate-based authentication, firewalls, and automated patch updates. Their routers are approved for government and finance industry use.
HMS Networks:
HMS also places security at the forefront with ISO 27001 certifications for Talk2M. Their solutions are GDPR-compliant and use VPN-based encrypted connections, securing critical factory data transmission between technicians and machinery.
Price and Value
Cost Comparison:
Digi’s pricing varies based on carriers, geographic deployment, and licensing of Digi Remote Manager. However, the hardware itself is generally well-priced given its features.
HMS takes the “buy once, use for years” approach. Hardware is pricier upfront but longevity and minimal maintenance (especially for protocol gateways) balance the cost over time.
