Hello friends, I’m Aravind Janardhanan, a cybersecurity professional with over 16 years in the OT, ICS, and IoT security space. I currently work as a Principal Architect – OT & xIoT Security in Dubai for a leading cybersecurity firm, helping organizations across the Middle East secure their industrial systems. I’ve been lucky to work with some great names along the way — Wipro, PwC, Ericsson, Garrett Advancing Motion, and MH Alshaya — leading projects that blend technology, security, and strategy.

I started OTInfraSecurity.com to share practical insights, frameworks, and lessons learned from real-world OT security projects. I’ve always enjoyed understanding technology deeply and explaining it simply — this platform is my way of giving back to the community. My mission is to simplify complex OT and ICS cybersecurity concepts, bridge the IT-OT gap, and inspire professionals and students to grow in this ever-evolving field.

Here, you’ll find content rooted in hands-on industry experience — covering topics in OT security, infrastructure protection, and general cybersecurity. Some posts begin with the basics, because I firmly believe that a strong foundation builds the tallest structures in cybersecurity. If you truly understand networks, devices, and operating systems, you can protect them effectively.

Outside of work, I’m passionate about continuous learning, traveling, and playing badminton and cricket. I believe in staying humble, grounded, and curious — both personally and professionally. If you share a passion for OT security, let’s connect, collaborate, and work together to build a safer industrial world.
