Secure network & internet
All OT traffic runs on our own secured stack in an EU datacentre, with UTM and strict segmentation. Carrier-agnostic — we pick the best route, not the vendor.

The challenge
The OT layer is the new attack surface
Batteries, EMS, inverters, PLCs, building systems, industrial controllers — more and more OT devices sit directly on the internet, often without segmentation, monitoring or current firmware. One compromised asset becomes a route into everything behind it.
NIS2 raises the bar and makes the whole chain liable. OT Networks closes that gap: we shrink the attack surface, move traffic onto a managed, secured stack and watch it around the clock — measurable against IEC 62443 and delivered to Security Level 3.
SL 3
IEC 62443 security level delivered as standard

eyes on screen in our own global NOC, around the clock
Services
One partner for your entire OT connectivity
Four building blocks, available separately or as one — all on a predictable monthly subscription.
IoT SIM connectivity
Managed IoT SIMs over a private APN, in volume tiers or unlimited with fair use. Firewalled on our stack, with full visibility of every device in the field.
24/7 monitoring & response
Our own NOC keeps eyes on screen around the clock. AI-powered monitoring surfaces anomalies fast, with version-controlled updates and mitigation starting within one hour. You know what happens in your OT network — so do we.
IEC 62443 assessments
A scan against the IEC 62443 security levels and a focused attack-surface-reduction sprint: 80%+ removed within five working days through SIM placement, firmware and segmentation.
Approach
From exposed to managed — in four steps
01
Scan
Inventory and IEC 62443 gap analysis. We map which assets communicate, how, and where to.
02
Segment
VLAN segmentation, default-deny and a tight zone model. We cut the attack surface down to what's needed.
03
Connect securely
Traffic moves onto our managed stack over a private APN and firewall. No more direct exposure from the field.
04
Monitor & respond
24/7 eyes on screen from our own NOC, version-controlled updates and mitigation that starts within one hour. Security is a subscription, not a project.
Why OT Networks
Engineered by people who know the field
Not a generic IT-security firm that does OT on the side. OT Networks grew out of nine years of hands-on work on network infrastructure for critical and industrial environments — in the lab and on site.
Security Level 3 as standard
Not a stretch goal we talk around — SL3 is what our solutions deliver, by design.
Our own connectivity proposition
We don't just advise — we own the connectivity layer. Secure SIMs, private APN, carrier-agnostic routing and an EU-hosted stack: one party for network, security and monitoring.
Proven in the energy market
Multiple references across the energy sector — battery storage, EMS and grid assets commissioned, segmented and monitored in production, not in a slide deck.
Fast to start
No months-long onboarding. A scan and attack-surface-reduction sprint start within days — and 80%+ of your exposure is gone within five working days.
Our own Global Network Operations Center
24/7 eyes on screen from our own GNOC. Not an outsourced helpdesk — our own engineers watch your network around the clock and start mitigation within the hour.
International, response-first
English-first and delivered across borders, with mitigation starting within one hour wherever your OT devices run.
Technology partners
We build on best-in-class, enterprise-grade hardware and security platforms.
