OT Cybersecurity for Local Utilities: Waterworks, Power Grids and Waste Plants with Zero Internal Resources

Local utilities (water operators, power distributors, waste treatment plants) are NIS2-regulated entities with security resources close to zero. SCADA systems 15 to 20 years old connected to the internet, run by a single technician: how to set up OT security from this starting point.

OT cybersecurity in logistics and automated warehouses: heterogeneous systems and high turnover

Modern automated warehouses run complex OT networks: a WMS wired to the automation, heterogeneous PLCs from many vendors, AGVs and mixed protocols. High turnover and frequent vendor work break segmentation, and downtime hits the supply chain instantly.

Incident response in OT environments: the critical differences from IT

IT incident response playbooks do not work in OT. Isolating a compromised system can halt production; powering off a device can cause physical damage. How to build OT IR that actually works.

OT Monitoring for MSSP Providers: What It Really Takes to Manage Multiple Industrial Clients

An MSSP offering OT monitoring needs more than a single-plant product: real multi-tenancy, clean SOC integration and alert handling at scale are what matter.

Which OT Monitoring Tools Help with IEC 62443 Compliance

IEC 62443 does not mandate a product, but many of its requirements can only be met with serious OT monitoring: asset inventory, anomaly detection, logging and verified segmentation. Which requirements map to which monitoring capabilities.

OT Network Topology: How to Reconstruct It When No Documentation Exists

OT network topology often lives only in a technician's head, or in a 2014 diagram that was never updated. Rebuilding it from scratch with passive traffic monitoring: why it is necessary and how it is done in practice.

OT threat hunting: chasing threats when the SOC and alerts are not enough

Reactive monitoring waits for an alert to fire. Threat hunting goes looking for the attacker the alerts never saw. How to apply threat hunting to OT environments, and why finding nothing is a good result.
