Secure, Mission-Critical Network Infrastructure for Transport for London (TfL)
Cisco delivers unified visibility across operational technology and enterprise networks, high-availability architecture for continuous transport operations, and secure networking for IoT-enabled systems serving millions of passengers daily across London's transport infrastructure.
Trusted by Public Sector and Infrastructure Leaders
Transportation agencies and critical infrastructure operators rely on Cisco to modernize their networks for secure operations and improved service delivery.
"“In partnership with Cisco, we were able to run either low cost or no cost pilots to demonstrate the use of technology.”"
"“We’re always looking at that vision. We’re trying to advance the students, trying to give them the opportunities that they need as they move forward and graduate.”"
"“Before, we were getting calls from our remote engineer saying, ‘Something’s wrong, something’s down, what’s going on?’. We didn’t have visibility into that infrastructure, but now, with Cisco agents [we do]. We can utilise a proactive point of entry for anyone to monitor and that’s been a game-changer.""
Questions about securing transport networks
We understand the complexity of protecting mission-critical infrastructure across stations, depots, buses, and control environments. Here are answers to common questions about network security for transport operations. More questions? Email us at info@cisco.com or connect on LinkedIn: https://www.linkedin.com/company/cisco/
Trials and demosHow do I get unified visibility across OT and IT networks in our transport operations?
Integrated observability tools provide a single view of network activity across operational technology systems (signals, ticketing, CCTV) and enterprise IT networks. This removes the need for separate monitoring consoles and helps your team identify issues faster across stations, depots, and control centers.
Can I maintain consistent passenger Wi-Fi performance across all stations and buses?
Centralized policy management applies the same configuration and security standards across all sites automatically. This eliminates policy drift and site-to-site variances, ensuring passengers experience reliable Wi-Fi whether they're at a station, on a bus, or in a depot.
Will this work with our existing transport systems and cloud infrastructure?
The solution integrates with existing operational technology systems through open APIs and supports hybrid cloud deployments. You can connect legacy transport control systems, modern IoT sensors, and cloud-based applications without replacing functioning infrastructure.
How do I secure OT networks and IoT devices across our transport systems?
Network security extends from OT control systems (SCADA, rail signaling) to connected IoT devices (sensors, cameras, ticketing machines) with built-in redundancy for high availability. Segmentation and access controls protect operational networks while allowing authorized communication between systems.
How do you help us de-risk migration and rollout for critical transport infrastructure?
We work with transport operators to plan staged deployments that protect service continuity. This includes validated pilot programs in controlled environments, clear migration paths with defined rollback points, and the option to run systems in parallel during transition periods. Changes are scheduled within agreed maintenance windows, and our technical teams provide hands-on support throughout the process to address issues quickly. The approach is designed to maintain availability and safety while moving to new infrastructure.
Build Secure Transport Infrastructure
We deliver proven secure networking architectures for operational technology and passenger-facing systems across metro and rail networks. Our validated pilot approach and phased migration plans reduce deployment risk, maintain continuous availability, and meet stringent safety and compliance requirements.
