Business internet for manufacturing & industrial
A network outage stops the line, and a stopped line costs real money by the hour. Manufacturing needs dedicated fiber with a real SLA, plus disciplined separation between the office network and the plant floor.
Top concerns we hear from manufacturing buyers
- • Uptime for MES/ERP systems (a down circuit can halt production and shipping)
- • OT/IT segmentation — keeping plant-floor equipment isolated from the business network
- • Fiber availability in older industrial parks (frequently near-net, not on-net)
- • Multi-plant consistency and centralized management
- • Large CAD/CAM and design file transfers between sites and suppliers
- • Ransomware — manufacturing is now the single most-targeted vertical
What you actually need
Dedicated fiber (DIA) with 99.99% SLA as primary, plus a cable or fixed-wireless backup behind SD-WAN failover — an idle production line is far more expensive than a redundant circuit. Strict OT/IT network segmentation so a compromised office PC can't reach a PLC. SD-WAN if you run 2+ plants. Enough symmetrical upload for design-file exchange with suppliers.
Compliance considerations
Most general manufacturing has light regulatory load. But if you supply defense, aerospace, or the federal supply chain, you likely fall under CMMC / NIST 800-171 (controlled unclassified information) and possibly ITAR — both of which drive real requirements around network segmentation, access control, and documented security. Confirm your contractual obligations before designing the network.
Recommended solution
Primary: Lumen or AT&T DIA fiber with 99.99% SLA at each plant. Backup: cable or fixed wireless behind SD-WAN. Segmentation: separate VLANs/firewalls for OT (plant floor) vs IT (office), with tightly controlled cross-zone rules. Security: managed firewall with intrusion prevention, OT-aware monitoring, and endpoint detection. Multi-plant: SD-WAN for centralized policy and easy site turn-up.
Carriers we recommend for manufacturing
Lumen
Strong price-to-SLA on dedicated fiber and a broad national footprint that suits multi-plant operations.
AT&T Business
Good coverage in Southern and Texas industrial corridors; solid managed-security options for OT/IT separation.
Comcast Business / Spectrum Business
Cable as a backup circuit behind SD-WAN — useful where a fiber build to an older park is slow.
📞 Voice considerations
Office phones plus plant-floor paging and overhead announcements. Hosted UCaaS covers the office cleanly; overhead paging and any analog endpoints (elevator phones, gate callboxes) need ATA gateways or a small POTS presence. Make sure critical inbound lines survive an internet outage.
🛡 Security considerations
Manufacturing leads ransomware targeting because downtime pressure makes payment likely. Baseline: hard OT/IT segmentation, managed firewall with IPS, endpoint detection (CrowdStrike, SentinelOne), email security, offline backups, and a tested recovery plan. Legacy machines running unsupported OSes should sit on isolated segments with no direct internet path.

FAQ
Is fiber even available at our plant?
Often yes, but many industrial parks are near-net rather than on-net, meaning a short build is required. We can confirm building-level status instantly and tell you whether it's a 30-45 day on-net turn-up or a longer near-net build.
Why separate the office and plant-floor networks?
If they share one flat network, a phishing click on an office laptop can reach the PLCs and HMIs running your line. Segmentation contains that blast radius. It's the single highest-value security move in a plant.
Do we really need a backup circuit?
If a network outage stops production or shipping, do the math on an hour of downtime versus the monthly cost of a backup circuit. For most manufacturers, redundancy pays for itself the first time it's used.
How do we connect multiple plants?
SD-WAN over dedicated internet at each site gives you centralized policy, easy new-site turn-up, and application-aware failover — usually a better fit than legacy MPLS for modern cloud-heavy operations.
