Tank Gauges Under Watch: Why a Quiet Industrial Device Class Just Became a Cyber Priority
A recent investigation into cyber intrusions targeting automatic tank gauge systems has pushed operators to harden a device class that often sits outside the spotlight but inside critical operations.
Industrial Crown Jewels Under Pressure as Cyber Adversaries Chase Disruption
The shift from stealing industrial data to threatening operational continuity changes how defenders must think about OT risk, critical assets, and recovery.
Dragos Bets on a Wider Blast Radius: Why the Phosphorus Deal Matters
The acquisition is a sign that industrial defenders are chasing more than network visibility, with xOT security now stretching toward the device layer itself.
Europe’s Critical Services Are Improving - But the Safety Gap Still Refuses to Close
ENISA’s latest NIS360 assessment shows uneven cyber maturity across NIS2 sectors, with some infrastructures moving ahead while others remain stuck in a mismatch between importance and resilience.
Factory AI Is Becoming a Security Boundary, Not Just a Productivity Tool
When AI starts steering scheduling, inspection, and logistics in manufacturing, the risk profile shifts from software convenience to operational trust.
When a Maritime Chokepoint Starts Pricing the Internet
The Strait of Hormuz is a reminder that digital fragility is not only a software problem: geopolitical tension can raise the cost of connectivity, slow infrastructure work, and make the global internet less resilient.
Maritime Recorder Weaknesses Put the Shipboard Black Box in the Crosshairs
A CISA advisory flags multiple credential and access-control flaws in MacGregor Voyage Data Recorder G4e devices, a reminder that safety recorders can become security liabilities when secrets are weak.
When a Charger Can Become a Computer: The XCharge C6 Fault Line
CISA’s advisory on the XCharge C6 shows how update trust, memory safety, and default access can collide inside connected charging equipment.
Washington’s New Logging Push Brings Industrial Networks Into the Watch Room
A federal cybersecurity directive is steering agencies toward centralized logging and AI-assisted detection for IoT and OT environments, with visibility now treated as a core defense layer.
NIST's FY2025 Report Maps the Pressure Points in AI, 5G, IoT, and Infrastructure Resilience
The annual publication is not an incident alert, but it does show where a major standards body is concentrating its cybersecurity and privacy work.
NIS2 Stops Being a Policy Debate and Starts Looking Like an Audit Trail
In Italy, the 2026 conversation around NIS2 is shifting from legal theory to operational proof, with board accountability, healthcare pressure points, and industrial-system resilience all under the microscope.
When Cyber Risk Becomes a Governance Problem, Critical Infrastructure Changes Its Rules
Critical services are now judged less by how many attacks they block and more by how well leaders can manage interdependence, safety, recovery, and public trust.
NIST Turns Ransomware Recovery Into an Industrial Survival Drill
A new public draft from NIST puts manufacturing recovery planning in the spotlight, where the real challenge is restoring operations without losing control of the plant floor.
Why Digital Care Fails When Health Data Still Lives in Silos
The real security challenge in healthcare is not scanning paper into a database, but making clinical data usable across systems without losing control, traceability, or trust.
Valencia’s Health Data Makeover Is Also a Security Test
A public health system built around unified records, cloud services, and clinical AI can improve care fast - but it also concentrates risk, governance, and accountability in one place.
Hospitals, Old Servers, and the New Compliance Trap Hidden in Plain Sight
In healthcare, a dead OTP or an unsupported gateway is no longer just an IT nuisance. Under NIS2, it can signal weak resilience, weak governance, and a regulatory problem that reaches well beyond the server room.
When the Perimeter Breaks, the Network Follows
A reported CRS finding about Iranian-linked access via Microsoft Exchange and Fortinet flaws is a reminder that internet-facing edge systems can become quiet entry points into critical environments.
Sustainable Data Centers Are Becoming a Test of Urban Planning, Not Just Power Bills
A growing class of data-center projects is being framed as a way to reuse disused land, support city regeneration, and make environmental performance measurable rather than rhetorical.
When Hospitals Hand Over the Keys, the Real Risk Moves to the Vendor
Healthcare outsourcing can improve efficiency, but only if the organization keeps control over access, data, continuity, and the risks that travel with third parties.
When a Router Becomes the Weak Link: Four-Faith Gear Draws Active Exploitation Pressure
A critical authentication bypass in Four-Faith F3x36 industrial routers shows how a single management-plane flaw can turn edge infrastructure into a security liability.
