Cybersecurity Hardening for PLCs: Steps That Work Without Breaking Production
Hardening a controller is different from hardening a server. Practical, low-risk measures for PLCs and their networks.
Historian vs Data Lake: Where Should Industrial Data Actually Live?
Historians are optimized for fast time-series; data lakes for flexible analytics. The two are complementary - if you design the boundary.
Data Quality in Manufacturing: Why Garbage Time-Series Breaks Analytics
The analytics model is only as good as the data pipeline that feeds it. The most common data quality failures and how to catch them early.
OT Asset Inventory: The Unglamorous First Step to Industrial Security
You cannot protect what you cannot see. How to build and keep an asset inventory that security and maintenance can both use.
IIoT Connectivity Options: Cellular, Wi-Fi, LoRaWAN, and Wired
There is no best wireless technology - only the right one for the distance, data rate, and power budget. A selection guide.
Ethernet vs Fieldbus: When Industrial Ethernet Wins and When It Doesn't
Fieldbus is not obsolete, and Ethernet is not automatically better. The engineering criteria that settle the debate.
USB and Removable Media in Industrial Environments: Real Risk, Practical Policy
A USB stick is still the most common way malware reaches a PLC network. How to control removable media without crippling workflows.
Edge vs Cloud for Industrial Data: A Decision Framework, Not a Religion
Cloud is not always the answer, and edge is not automatically safer. A practical framework for where processing should live.
How Time-Series Database Compression Keeps Historians Fast
Historians store billions of samples without exploding in size. Understanding lossless and lossy compression helps you size and tune them.
