When the factory floor goes online, the hacker does too.

Let’s secure the moment.

The world of Operational Technology (OT) is no longer air-gapped. With digitisation, IIoT, cloud connectivity and hybrid OT/IT architectures, the attack surface is expanding fast.

Key realities every architect must own:
1. Availability is the pedigree.
In OT environments (energy, manufacturing, infrastructure) uptime is critical. Security designs must prioritise process integrity and availability.
2. Attackers are moving from IT to OT.
Ransomware, state-backed actors, zero-day exploits: OT is now a primary target—not just collateral.
3. Legacy + modern = risk compound.
Old PLCs + modern connectivity = a recipe for mis-configuration, unsupported firmware and blind spots.
4. Governance + visibility still matter.
You need asset inventory, segmentation (IT/OT zones), anomaly detection, consistent policy enforcement, and board-level responsibility.

🔍 Practical play as a Cloud Security Architect
Map your OT estate like you do your cloud estate: owners, zones, dependencies, data flows. Extend the cloud security mindset (least privilege, zero-trust, automation, telemetry) into OT. For hybrid/connected systems treat them as one ecosystem.
When operations and security speak two languages, failure is inevitable.

CTA: Schedule a “first ten” audit of your OT-connected digital estate: top 10 assets, top 10 risks, top 10 controls missing. Start the conversation now.
