ITinOT reads as IT in OT: information technology inside operational technology. In other words, what happens when IT meets the industrial systems that run plants, water and energy networks, and infrastructure. This blog is about how those operational technology (OT) systems are connected, and how to maintain and secure them without impacting production.
The author
With 25 years of professional experience, the founder and writer of ITinOT.com comes from industry, after a rich career spanning a range of roles in the automotive, rail and aerospace sectors. That path gradually led to IT, and to unique knowledge built where the worlds of IT and OT meet.
Today, the goal is to share that expertise in IT in OT, a field that is still little known and yet critical for businesses.
What you will find
- OT Basics: the vocabulary and building blocks of industrial systems, explained for IT people and newcomers.
- Industrial Networks & Connectivity: how plants are wired, from field networks to remote access and the industrial DMZ.
- OT Cybersecurity: the fundamentals of protecting control systems, where availability and safety come first.
- Standards & Regulations: IEC 62443, NIS2 and the other texts that shape the field, in plain language.
- IT/OT Convergence: the boundary between IT and the plant, from the industrial DMZ to getting data to IT and the cloud, and who owns what between IT and OT teams.
- Incidents & News: analysis of public incidents and advisories, and what they mean in practice.
Editorial principles
- No client names, no site names, no details that could identify an installation.
- Incidents are covered only from public, named sources (national CERTs, CISA, ENISA, vendor advisories), and those sources are linked.
- Vendor-neutral: no sponsored content and no affiliate links.
- Errors get corrected. If you spot one, please say so.
Articles are general information, not an assessment of your installation. In OT, a change can affect production and safety: always validate it in your own context, with the people responsible for the process.
