Cisco Industrial Ethernet Switches provide secure, high-performance connectivity for demanding operational environments, combining rugged hardware with advanced security, resilience and IT/OT integration. Designed for harsh conditions, the portfolio includes DIN-rail, rack-mount, IP67-rated and embedded options that can support reliable networking across distributed maritime infrastructure.
For maritime and offshore organisations, Cisco's rugged switch range provides a strong foundation for secure and resilient operational networks. It delivers a variety of compact and modular options, with features including Gigabit Ethernet, 10-GE uplinks on selected models, PoE and high-wattage PoE options, resiliency protocols, secure remote access, segmentation and device visibility.
The range includes modular platforms such as the IE3500, IE3400 and IE3300 for scalable deployments, as well as fixed and compact options such as the IE3200 and IE3100 for constrained environments and machine integration. Advanced features available on selected models include Cisco Catalyst Center management, Cisco IOS XE, Cisco TrustSec, Cisco Cyber Vision and Cisco Secure Equipment Access.
