narrowin — Courses. Hands-on OT network & security courses.

[ Scheduled courses ]

Two courses, both hands-on, both in the lab.

Run twice a year at the FHNW, two days each and strictly practice-oriented. You leave with in-depth know-how and concrete recommendations for action, and the experience of having done it, not just seen the slides.

Course 01

Designing Secure and Reliable OT Networks

Reliable, secure OT networks are not rocket science. This hands-on course covers the essential network and security concepts: VLANs, modern routing protocols and Spanning Tree, through to redundancy and VPN technologies for remote maintenance and secure site connectivity. You learn how to prevent failures and raise security, with direct application in the OT Network Lab.

Course 02

OT Attack Mapping & Risk-Based Defense

Lateral movement, man-in-the-middle attacks, RFID cloning and more. Which attacks are genuinely relevant, and which are myth and marketing hype? You analyse real OT attack scenarios, identify the critical issues, and develop pragmatic countermeasures with clear priorities. Hands-on, practical, and applicable to your own OT environment.

[ Stay current ]

OT Deep Dives: our online webinars.

Between courses we run free online Deep Dives on current OT network and security topics: microsegmentation, AI for troubleshooting, scalable OT-WAN, OT IDS and more. The continuous follow-up for course participants, open to anyone working in OT.

[ The lab ]

Every course runs in the OT Network Lab.

The courses are taught in our ContainerLab-based lab: fully virtualised OT topologies you can configure, break and defend with zero risk to production. The same lab does more than training: it validates network designs and rehearses failure scenarios before they reach the real plant.

[ What you take away ]

More than a certificate.

The courses translate current standards into concrete measures, and give you the room to test them against your own reality.

An OT network course in session at the FHNW in Olten: participants at laptops, an instructor, and an RSTP lab on screen

01

Current topics, and your blind spots

An update on where OT security stands today, and the chance to identify the gaps in your own environment before someone else does.

02

Your own use cases

Bring your own questions and scenarios. There is deliberate room to discuss the situations you actually face, not just the textbook ones.

03

Community and exchange

Two days with like-minded professionals from across OT, and the chance to learn from each other's experience, not only the lecturers'.

[ Lecturers ]

Taught by people who do the work.

The courses are led by practitioners: from incident response, from network engineering, and from research.

[ In collaboration with ]

These courses are run in collaboration with the FHNW (the University of Applied Sciences Northwestern Switzerland) and taught at its campus in Olten.

[ Custom courses ]

Or a course built around your environment.

Beyond the scheduled FHNW courses, we run company-specific courses: for a single team, on your own topology, focused on the situations you actually face. Same hands-on format, same OT Network Lab, shaped around you.

01

Your topology

Built on your actual network design and equipment vendors, so what participants practise on is what they go back to.

02

Your scenarios

Focused on the failures, attacks and changes your team really deals with, not a generic curriculum.

03

Your team

Depth and pace tuned to the room, from operations and maintenance through to network and security engineers.
