Swiss Sovereignty Tests the Limits of Critical Cloud Dependence
When essential platforms sit inside critical infrastructure, the security debate shifts from features to control, portability, and the right to leave.
The Hidden Math That Keeps Grid Power From Going Ragged
Harmonic filters sit in the background of modern power systems, trimming waveform distortion so AC networks stay compatible with the equipment that depends on them.
Fitch Draws a Hard Line Between Cyber Failure and Credit Failure
For water and healthcare organizations, the rating question is no longer whether an attack happens, but whether the institution can absorb it and keep operating.
When Hospitals Go Paper-First: Romania's Cyber Outage Exposed a Fragile Medical Backbone
A disruptive cyber incident pushed Romanian hospitals into manual workflows, showing how quickly patient care can depend on pens, paper, and preplanned downtime.
Inside the Hospital Blackout: What a Bulgarian Cyber Outage Reveals About Clinical Survival
When healthcare systems go offline, the real emergency is continuity of care, not just the intrusion itself.
NIST Shrinks OT Defense Into a First Move for Understaffed Building Teams
A new quick-start infographic is aimed at resource-constrained BACS operators, signaling that even modest OT environments need a practical security baseline.
When a PLC Stops Being “Just a Controller”: The Siemens S7 Warning That Put OT Exposure in the Spotlight
A joint U.S. advisory points to active targeting of Siemens S7 controllers, showing how an internet-reachable industrial device can become a path into physical processes.
When Zero Trust Meets the Control Room, Security Stops Being Abstract
In electricity-focused OT environments, the real challenge is not whether to adopt Zero Trust, but how to do it without disturbing the systems that keep physical operations running.
When AI Meets PLCs, the Real Prize Is Control
A cybersecurity advisory from NSA, CISA and other agencies says hackers are using AI to target Siemens PLCs in critical U.S. sectors.
AI-Style Scripts Put Siemens S7 Controllers in the Crosshairs
U.S. agencies warned about a campaign targeting Siemens S7 PLCs with scripts described as AI-generated and disguised as ordinary industrial monitoring tools.
Capitol Hill Eyes the Grid’s Weak Link: Cryptography Before Quantum Hardware Arrives
A bipartisan Senate bill puts post-quantum readiness into critical-infrastructure policy, even though the technical threat remains forward-looking.
When the Cooling Room Becomes the Front Door
A reported count of 6,300 internet-reachable ICS and BAS devices points to a quiet but consequential exposure inside US data centers: the control layer behind uptime.
AI in OT Has Left the Slide Deck - and That Changes the Risk
A discussion framed around the move from hype to operational reality in industrial AI points to a harder truth: once AI touches OT, safety, availability, and change control matter as much as model performance.
When Water Becomes a Target: The Hidden Cyber Risk Behind a Geopolitical Resource
A commentary about water politics also points to a harder truth: once a resource is digitized, the control systems around it can become part of the threat model.
Europe’s Rail and Sea Routes Just Got a Cyber Stress Test
A major EU exercise put railway and maritime disruption scenarios under pressure, revealing why transport security is as much about coordination as it is about code.
When Device Security Becomes a Signal Problem: Crytica and Forescout Connect the Dots
An announced integration between Crytica Security, Forescout, and Vistaro points to a familiar enterprise dilemma: turning device-level alerts into something operators can actually trust and act on.
When OT Data Enters the SOC, the Blind Spot Gets Smaller
Nozomi Networks and Sophos are tying industrial visibility into investigation workflows, a move that could narrow one of security’s most stubborn gaps: seeing what happens when IT and OT overlap.
When Visibility Becomes a Trap: Why OT Networks Need Real Protection
In industrial environments, seeing every device is useful, but it is not a defense unless the network itself can enforce limits, isolate risk, and preserve safety.
548 Internet-Exposed Building Automation Devices Still Run Software Past Its Security Lifespan
A security study found 548 internet-exposed building automation devices near U.S. data centers running end-of-life products with no future security patches.
When a Factory Incident Becomes a Supply-Chain Problem
A reported share of UK manufacturers is pushing cyber risk out of the IT corner and into the boardroom, where continuity, suppliers, and recovery now matter as much as passwords.
