OT managed services
Industrial networks that stay connected, secure and running
We bring ISP-grade connectivity and MSP-grade management to critical infrastructure, from the plant floor to the substation, so your operations stay online and protected.
The IT/OT divide
Where industrial networks break down
Operational technology was built to run for decades, not to sit on a connected network. We close the gaps between your IT and OT.
The challenge: downtime risks
When a line, pump station or control system loses its network, work stops. Many industrial sites still rely on one connection and on equipment no one watches after hours.
How we solve it
Connections built to stay up
- Resilient fiber backhaul, with private cellular routing as another path
- Managed SD-WAN that keeps remote facilities connected
- Proactive monitoring from our unified NOC/SOC, 24/7
- Uptime SLAs tied to your physical production goals
The challenge: legacy vulnerabilities
Controllers, HMIs and sensors often run for years on software that can't be patched like an office computer. Many were never designed to be reachable from a network at all.
How we solve it
Protection for equipment you can't replace
- Continuous asset discovery, so every connected device is known
- Threat monitoring aligned with the NIST framework
- Network segmentation that walls older equipment off
- Lifecycle management of ruggedized hardware
The challenge: air-gap breakdowns
OT networks that were once isolated now connect to business systems, cloud dashboards and vendors who log in from outside. Each new connection is another way in.
How we solve it
Controlled connections between IT and OT
- Segmentation between business and production networks
- Secure remote access for third-party vendors
- Continuous threat monitoring across both networks
- One team responsible for the IT and OT sides
Core OT pillars
One partner for connectivity, security and operations
Three managed services that work together, from the connection into your site to the devices on the floor.
Industrial connectivity
Connections for plants, yards and remote sites that can't afford to go dark.
- Managed SD-WAN for remote facilities
- Resilient fiber backhaul
- Ruggedized private cellular and IoT routing
OT cybersecurity and compliance
Visibility and control over every device on your production network.
- Continuous asset discovery
- Threat monitoring aligned with the NIST framework
- Network segmentation
- Secure remote access for third-party vendors
24/7 co-managed operations
We work alongside your engineers and plant teams, around the clock.
- Proactive monitoring from our unified NOC/SOC
- Lifecycle management of ruggedized hardware
- Uptime SLAs tied to physical production goals
Industries
Built for the places work actually happens
How OT managed services fit each kind of operation.

Keep production lines connected and protected
Plant floors mix new robotics with controllers that have run for years. We connect them reliably and keep them apart from office traffic.
- Segment PLCs, HMIs and robotics away from business systems
- Give machine builders secure remote access instead of always-on connections
- Find every connected device on the floor with continuous asset discovery
- Pair fiber backhaul with cellular routing so one outage doesn't stop the line

Connect and protect substations and remote sites
Utilities run equipment spread across wide areas, often far from a fiber route. We link those sites and watch them around the clock.
- Managed SD-WAN linking substations, pump stations and remote sites to central operations
- Ruggedized private cellular and IoT routing for field sensors
- Threat monitoring aligned with the NIST framework
- Segmentation between control systems and the business network

Run building systems on a managed, secure network
HVAC, lighting, access control and cameras now depend on the network. We keep building systems connected and separate from tenant and office traffic.
- Segment building automation, access control and cameras from tenant networks
- Secure remote access for the vendors who service building systems
- 24/7 monitoring of building system networks
- Lifecycle management of ruggedized controllers and network hardware

Keep warehouses, yards and vehicles connected
Distribution depends on scanners, conveyors and vehicles staying online. We connect every site and the equipment moving between them.
- Ruggedized private cellular routing for vehicles, yards and temporary sites
- Managed SD-WAN across warehouses and distribution centers
- IoT routing for trackers, sensors and handheld devices
- Segmentation that keeps warehouse automation apart from business systems

FAQ
OT managed services questions
OT managed services cover the networks and connected equipment that run physical operations, such as production lines, substations, building systems and warehouses. 5x5 provides the industrial connectivity, OT cybersecurity and 24/7 co-managed operations behind them.
IT runs business systems such as email, files and finance. OT runs physical processes through controllers, sensors and machines. OT equipment often stays in service for many years and can't be patched or restarted like office computers, so it needs different protection.
We find every connected device with continuous asset discovery, segment older equipment away from other networks and monitor for threats in line with the NIST framework. Hardware lifecycle management keeps ruggedized equipment supported over time.
We set up secure remote access for third-party vendors, so machine builders and service providers reach only the systems they support, instead of through always-on connections.
No. Our co-managed model works alongside your team. We provide 24/7 monitoring from our unified NOC/SOC and hardware lifecycle management, and your people keep control of the process.
We look at how your industrial network, connections and remote access are set up today, ask a few screening questions about your operation and share general recommendations. Testing and hands-on work are scoped in the plan we propose.
