Semtech and Palo Alto Networks Secure Industrial IoT with Zero Trust

Semtech Corporation has completed a product integration with Palo Alto Networks Next-Generation Firewalls (NGFWs). Semtech joins an extensive ecosystem of Palo Alto Networks Technology Partners to deliver intelligent and interoperable solutions that help joint customers drive resilience and compliance, securing the most complex environments.

The integration combines Semtech’s AirLink® secure edge 5G/LTE routers and network management portfolio with Palo Alto Networks NGFWs — industry-leading firewalls that leverage machine learning for proactive protection and comprehensive visibility and control — along with Next-Generation Trust Security (NGTS) and Zero Touch Public Key Infrastructure (ZTPKI) solutions to enable operators to scale their connected infrastructure with confidence while reducing complexity and strengthening resilience against evolving threats. As utilities and critical infrastructure operators deploy thousands of connected assets across distributed networks, including wired, cellular and satellite connections, this Zero Trust solution secures these assets at scale, solving a key challenge in operational technology.

“Threats to critical infrastructure are accelerating, with Frontier AI compressing attack timelines while many operational technology assets cannot be patched quickly—or at all,” said Mitch Rappard, director of technical solutions at Palo Alto Networks. “Together, Palo Alto Networks and Semtech are extending Zero Trust security to the industrial edge by combining resilient AirLink cellular connectivity with continuous asset visibility, operational risk prioritization and AI-powered threat prevention. This enables operators to enforce protections without disrupting critical services, secure distributed deployments from edge to core, and build a scalable foundation for today’s threats and the evolving security landscape.”

“Securing utility networks at scale requires partners who understand both the operational realities of the field and the demands of modern cybersecurity. The collaboration between Semtech and Palo Alto Networks represents exactly the kind of integrated, standards-aligned approach our members expect to protect critical infrastructure while keeping pace with digital transformation,” said Bobbi Harris, executive director of the Utility Broadband Alliance (UBBA).

“Utilities and critical infrastructure operators are managing increasingly complex, distributed environments where a single security gap can have far-reaching consequences,” said Kinana Hussain, vice president, AirLink Networking Solutions at Semtech. “Securing distributed industrial assets requires both trusted connectivity at the edge and robust enforcement at the core. Our partnership with Palo Alto Networks brings together best-in-class mission-critical edge connectivity and enterprise-grade security to deliver a Zero Trust architecture that is both operationally practical and field-proven at scale.”
