When Critical Systems Must Survive the Cut: The New Discipline of OT Isolation
Fresh joint guidance for critical infrastructure turns a hard reality into a planning problem: isolate the systems that keep essential services alive, and make sure they can run that way for longer than a few hours.
Nozomi’s CEO Reset Puts OT Security’s AI Ambitions Under the Spotlight
Andrea Carcano’s return as CEO is more than a corporate shuffle - it signals how industrial security vendors are trying to turn AI, visibility, and safe response into one product story.
Frenos Gets Fresh Capital as OT Security Bets on Safer Simulation
A $1.52 million funding round points to growing interest in tools that can model industrial attack paths without disturbing fragile production systems.
The Air-Gap Myth: Why Isolation Is Not the Same as Security
Offline networks reduce remote exposure, but removable media, insider access, supply-chain flaws, firmware trust, and side channels still define the real attack surface.
Why Exposed PLCs Turn Industrial Networks Into Open Doors
A joint U.S. warning puts internet-facing controllers at the center of a critical infrastructure risk: when PLCs are reachable from the outside, normal industrial protocols can become a path into the control layer.
Inside the PLC Trap: Why Trusted Engineering Tools Became the Weak Link
A warning tied to Iranian-affiliated activity points to a grim industrial lesson: when controllers are reachable from the internet, legitimate maintenance software can become a weapon against physical operations.
When a Simulation File Becomes a Loader: Rockwell’s Arena Fix Exposes a Quiet Industrial Risk
Rockwell has patched code-execution flaws in Arena Simulation, and the case shows how trusted engineering files can turn workstation software into an entry point.
When the Screen Lies: Industrial Controllers Turned Into a Cover Story
A revised federal warning points to a dangerous OT pattern: internet-exposed PLCs and tampered HMI displays can leave operators watching a system that no longer reflects reality.
Control Rooms Under Pressure: A PLC Advisory Puts OT Integrity in the Crosshairs
A revised federal advisory on PLC targeting highlights a danger that matters more than theft alone: when attackers can tamper with logic and the operator view, trust in the industrial process itself starts to erode.
When an Old Waiver Meets a New Cyber Rule, the Waiver Loses
The Coast Guard has drawn a clear boundary in maritime compliance: a past MTSA waiver does not automatically erase cybersecurity obligations.
Why an Advisory About PLCs Matters More Than a Blunt Attribution Label
U.S. agencies have refreshed a warning about Iranian-affiliated activity aimed at internet-connected PLCs, and the real story is the risk that remote convenience becomes operational exposure.
Stormbreaker Puts the Grid’s AI Hype Under a Harder Test
CESER’s new evaluation effort is a reminder that in power systems and OT, AI is not judged by accuracy alone but by whether it behaves safely under operational stress.
When PLCs Become Pressure Points: The Critical-Infrastructure Warning Hitting Water and Energy
U.S. agencies are flagging a familiar but dangerous pattern: vulnerable industrial controllers can turn a narrow intrusion into disruption across water and energy environments.
Military Cyber Drill Turns Toward the Plant Floor as OT Becomes the New Battleground
Cyber Shield 2026 places a stronger emphasis on operational technology defense, signaling that resilience now means protecting systems that interact with the physical world, not just office networks.
Industrial Cybersecurity Moves Up a Layer as A2LA Broadens ISASecure Scope
The accreditation change does not describe a breach or a flaw, but it does matter: it shapes who can validate ISA/IEC 62443 certification in industrial automation security.
The Quiet Threat Hiding in Factory Controllers
An updated federal advisory puts PLC security back under the microscope, where exposed industrial controllers and weak access controls can turn a small intrusion into an operational problem.
When a PLC Goes Public, the Plant Becomes the Target
U.S. critical infrastructure operators are being pushed to pull Rockwell and other controllers off the public internet, because exposed OT gear changes a maintenance shortcut into a security hazard.
Industrial Security’s Hidden Pressure Point: Why AI and Supply Chains May Be Widening the Vulnerability Gap
A vendor-backed threat review points to a sharp rise in industrial and connected-device vulnerabilities, but the deeper story is how shared components, remote management, and AI-assisted discovery can strain IoT and OT defenses.
When the Login Is the Breach: Critical Infrastructure’s Identity Problem
A security argument aimed at critical systems is getting sharper: if access depends on a password alone, the trust chain may already be too weak.
When GPU Jobs Start Looking Like a Grid Signal
Bit2Watt is being framed as a research warning: ordinary cloud GPU use could, in some setups, modulate data-center power fast enough to matter beyond the server room.
