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. And it is not just energy: the refrigeration in a supermarket, a cold store or a pumping station runs on the same kind of connected controllers. 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
< 1 hr
to start mitigation, day and night
80%+
of your attack surface removed within 5 working days
24/7
eyes on screen in our own SOC, 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 24/7 SOC 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 SOC, version-controlled updates and mitigation that starts within one hour. Security is a subscription, not a project.
Security Operations Center
Our own 24/7 SOC. Eyes on screen.
Your OT network is watched by people, not just dashboards. Analysts in our own Security Operations Center keep eyes on screen around the clock, triage alerts as they fire and start mitigation within the hour — backed by our global NOC for the network layer.

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 24/7 SOC and global NOC
Eyes on screen around the clock from our own Security Operations Center, backed by our Global Network Operations Center. Not an outsourced helpdesk — our own analysts and engineers watch your network and start mitigation within the hour.
