Cybersecurity in Automation: Why the Future is Moving Beyond WiFi-Only Systems
Guest blog by MHI members Conductix-Wampfler and SAVOYE North America
As automation continues to evolve across warehousing, distribution, and manufacturing environments, cybersecurity is no longer just an IT discussion — it has become a critical operational priority.
For integrators and end users alike, the conversation is shifting from simply “what works” to “what is secure, scalable, and sustainable long term.” While WiFi-enabled automation systems have become common across facilities, many organizations are beginning to recognize the limitations and vulnerabilities that come with relying solely on wireless infrastructure.
We’ve seen firsthand how customers are reevaluating their automation strategies with cybersecurity, reliability, and uptime at the forefront. That’s why partnerships with innovative technology providers have become a game changer in how we design and deliver automation solutions.
The Challenges of WiFi-Only Automation Systems
Wireless communication has its place in modern facilities, but depending exclusively on WiFi for critical automation systems can create unnecessary operational and cybersecurity risks.
Here are five of the most common challenges we’ve seen organizations face with WiFi-only automation environments:
1. Increased Cybersecurity Exposure
WiFi networks create additional attack surfaces for unauthorized access, malware, and network intrusion. As automation systems become more connected, the risk profile expands significantly.
2. Signal Interference and Connectivity Disruptions
Large facilities filled with steel structures, equipment, and moving machinery can interfere with wireless signals, causing latency, communication drops, or operational interruptions.
3. Network Congestion
As more devices connect to a wireless infrastructure, bandwidth limitations can impact system responsiveness and performance — especially in high-throughput operations.
4. Downtime Risks
Even brief communication interruptions can impact automation performance, production schedules, and order fulfillment timelines, leading to costly downtime.
5. Scalability Challenges
As facilities expand and automation grows, maintaining secure and reliable wireless coverage becomes increasingly complex and resource-intensive.
6. IT/OT Convergence Risk
As traditional IT networks become increasingly integrated with operational technology (OT) infrastructure, cybersecurity threats can have direct operational consequences. A breach or disruption that once affected only data systems can now impact automation performance, equipment availability, worker safety, and business continuity — making secure, resilient connectivity strategies more critical than ever.
The Value of Non-WiFi Automation Solutions
To help customers address these challenges, leading firms are investing in technologies that reduce dependency on traditional wireless communication while improving operational resilience.
Non-WiFi communication solutions can provide several advantages, including:
• More secure communication pathways
• Reduced vulnerability to external cyber threats
• Improved system uptime and reliability
• Lower risk of signal interference
• Consistent communication performance in demanding industrial environments
• Greater scalability for future automation growth
• These technologies are helping organizations build smarter and more resilient automation ecosystems without sacrificing operational efficiency.
“Today’s customers are looking beyond basic connectivity — they want automation systems that are secure, reliable, and built for long-term performance,” said Bryan Doherty, Senior VP of Integration and Automation Technologies at SAVOYE North America. “The convergence of IT and operational technology environments has elevated cybersecurity from an IT concern to a core operational risk. Reduced reliance on traditional WiFi infrastructure can deliver automation solutions that improve security posture, operational continuity, and overall system confidence for our customers when needed.”
Panos Gamvroudis, Product Manager – Controls & Automation at Conductix-Wampfler, has also seen firsthand the impact these solutions are delivering across increasingly connected automation environments.
“As automation systems become more connected and data-driven, customers need a communication infrastructure they can depend on — not just connectivity,” said Gamvroudis.
Building the Future of Enhanced Security
The future of automation is not simply about increasing speed or throughput — it’s about building systems that are resilient, secure, and capable of supporting long-term operational growth.
As cybersecurity concerns continue to rise across industrial environments, organizations must evaluate whether their current infrastructure is truly designed for the demands of modern automation.
