OT Exceptions, Vendor Access, and Connectivity Expose Whether Governance Is Real
Do not judge an OT program by its slide deck. Judge it by what happens when the plant cannot patch, the OEM needs remote access, and the shutdown window is gone. That is where the truth shows up. Most OT organizations say they have governance. Plenty of them do. On paper. They have standards. They […]
A Useful OT RACI Starts With Decision Rights, Not Departments
A RACI that looks clean in PowerPoint usually fails in the first real conflict. That is not because RACI is useless. It is because most companies use it to map functions instead of decisions. Security gets a box. Engineering gets a box. Operations gets a box. Somebody adds safety, procurement, and risk because the matrix […]
Why we built Resilion
A decade securing Fortune 500 OT environments by hand, and why we turned that into a platform.
OT Governance Has to Cross Security, Engineering, Operations, and Safety
The real OT problem lives in the seams. That is where standards collide with uptime. That is where safety collides with cyber urgency. That is where a clean enterprise control meets a dirty plant reality and nobody wants to own the tradeoff. Most manufacturers understand this at a gut level. Few structure around it. They […]
The Competitive Advantage of Disclosure Readiness: Why the Best Manufacturers Will Embrace Transparency
Disclosure readiness is not a compliance burden. It is a strategic capability that separates the manufacturers investors trust from the ones they do not. Here is why the best will embrace it willingly. By Roger Hill The Argument Nobody Expects For four weeks, I have been laying out problems. The SEC’s four-day materiality clock does […]
Building a Board-Ready OT Materiality Framework Before You Need It
A practical framework for pre-defining OT incident materiality thresholds across production impact, safety, environmental, regulatory, and financial dimensions. Build it now, or build it during a crisis. Your choice. The Framework You Wish You Had Three weeks into this series, I have laid out the problem from multiple angles. The SEC’s four-day […]
Incident Forensics vs. Disclosure Timelines: The Manufacturing Double Bind
OT incident investigation takes weeks or months. The SEC wants a materiality determination “without undue delay.” Welcome to the hardest operational problem in cybersecurity disclosure. You Cannot Image a Running PLC Let me describe something that happens in IT incident response so routinely that nobody thinks about it anymore. An analyst detects […]
The OT Disclosure Gap
What Your 10-K Is Missing (And What Regulators Will Notice) Most manufacturers’ annual risk factor disclosures describe OT risk in IT language. That gap is about to become visible to regulators, investors, and plaintiffs’ attorneys alike. The Filing Nobody Reads Until It Matters Every publicly traded company files an annual 10-K with […]
The Clock Nobody Planned For
Four business days… That is the window the SEC gives a publicly traded company to file a Form 8-K under Item 1.05 after determining that a cybersecurity incident is material. Four business days to describe the nature, scope, timing, and material impact of the event. Four business days to tell the investing […]

Governance and Reporting That Scales
Every OT security leader knows the moment when good intentions meet reality: the dreaded quarterly report. Data lives in a dozen spreadsheets. Evidence is scattered across folders. Findings from assessments are written in different formats, and no one agrees which version is current. By the time the report is ready, it’s already […]
Contextualized Collaboration in OT Security
In every company, people talk all day, on calls, in chat, in meetings. The problem starts when no one remembers what they were talking about. People talk all day across Slack, Teams, and email. The problem is that conversations are detached from the work they’re about. By the time someone searches […]
Operational Translation for OT Security
Security and operations often speak different languages. Security talks in frameworks, controls, and audit findings. Operations talks in uptime, throughput, and safety. Both sides care about resilience, but they describe it differently. The result is friction that slows progress, not because people disagree, but because they misunderstand each other. Operational translation is […]
Agile OT Assessments That Fit Plant Schedules
Plant managers don’t need another survey. They need time. And time is the one thing they never have. If you’ve ever tried to run a security assessment in an operating plant, you already know the problem. Every minute of downtime costs production. Every hour in a conference room pulls skilled people […]
OT Framework Alignment with AI
When industrial companies expand globally, their OT security programs become tangled in a web of overlapping standards and regulations. A manufacturer with plants in Germany, the United States, and Australia might find itself juggling IEC 62443, NIS2, NIST CSF 2.0, SOCI, FDA guidance, and a patchwork of internal corporate standards. Each […]
Building Resilient, Explainable AI Systems: The Hard Truth About Trustworthy Autonomy
Designing AI That Stands Up to Scrutiny and Stress Factories do not forgive fragile systems. A pump that cracks under thermal stress, a sensor that drifts out of calibration, a safety system that fails under real load all of them eventually cause production losses or worse. The same is true for artificial […]
Ethics & Accountability in Industrial AI: Why Trust is Your Hardest Asset to Build
Aligning with NIST AI RMF to Build Trust Manufacturing lives and dies on trust. Just ask any plant manager. The night supervisor counts on valves opening the moment they’re needed. Engineers bet their reputations on PLC code standing firm under pressure spikes. Safety teams stake lives on emergency systems […]
When Cyber-Physical Systems Collide with Privacy and IP: Preparing Manufacturing for AI’s Next Chapter
AI and LLMs are beginning to blur operational, privacy, and intellectual property boundaries – boards must set the guardrails now A change that will catch leaders off guard Factories were designed to optimize throughput and protect physical safety.

What Is Operational Risk Costing You?
Why is treating OT cyber risk as a budget-neutral technical problem costing you far more than you think? “If OT risk isn’t on your balance sheet, you’re not managing it – you’re absorbing it.” Operational risk is expensive. But not in the way most people think. It’s not just […]
12 Plants, 12 Programs: Why Site-Level Risk Can’t Scale
Enterprise OT resilience demands more than strong sites—it demands unified governance. “You don’t need twelve programs. You need one model that flexes.” Every plant has a story. However, not every plant should have its own program. In OT security, site-level autonomy has its place. Operational nuances, local vendor ecosystems, […]
The Silent Drift: Operational Gaps That Compound Into Crisis
Why the most significant risks to your OT environment aren’t sudden threats – they’re slow, silent shifts in process, behavior, and control. “Most major OT failures don’t begin with a breach. They begin with something quietly neglected.” Some risks make headlines. Others build in silence. In operational environments, security […]
When Patching Won’t Protect Your Factory
Roger Hill June 7, 2025 Why Smart OT Security Leaders Are Moving Beyond Vulnerability Metrics Spend enough time in manufacturing cybersecurity and you’ll start to see a pattern. Visit a major site, meet the OT security team, and someone will pull up a dashboard (or more than likely a spreadsheet). More often than not, the […]
The Value Gap in OT Security: From Telemetry to Trust
Why more data hasn’t made us safer, and what actually builds confidence in cyber-informed decisions. “The real problem isn’t a lack of visibility. It’s a lack of context.” We’re drowning in telemetry. Device scans. Asset inventories. Traffic anomalies. Risk scores. The issue for most OT security teams isn’t data collection, it’s data […]
The OT Risk the CFO Can’t See
Why operational cyber risk still escapes financial oversight—and how innovative leaders are fixing it. May 29, 2025 “What gets reported gets funded. And if your OT risks aren’t reported in business terms, they don’t exist at the executive table.” If your CFO asked for your top 3 OT cyber risks, could you […]
How to Build a Sustainable OT Vulnerability Management Program
From project to practice: embedding VM in your OT security lifecycle There’s no shortage of urgency when it comes to OT vulnerability management. The threat landscape keeps expanding. Regulatory pressure keeps mounting. And vendors keep promising solutions that will solve it all with one more sensor, scanner, or platform. But if experience […]
You’re Not Stuck – You’re Normalizing Risk
What Happens After the Duct Tape Phase in OT Security Temporary fixes and improvisation helped early OT programs survive. But what happens when those unowned decisions become a material exposure? Start Where the Board Feels It — Governance, Not Controls In every audit or resilience review, we ask the […]
Mapping OT Business Risk Using the QUICK Framework
Why Understanding What’s ‘Critical’ To The Business Is More Important Than Scoring Systems One of the hardest things to explain to people outside the plant is that not all assets carry the same weight. A vulnerability on one controller might be a nuisance, while the same issue on another could cost […]
The RISE Model: Prioritizing OT Vulnerabilities Where It Matters Most
Focus Limited Resources Where They’ll Deliver Maximum Impact If every vulnerability were equal, our jobs would be a lot simpler. We could line them up, knock them down, and call it a day. However, the reality inside OT environments tells a different story. One where not all vulnerabilities are worth the same […]
The Boardroom’s Blind Spot: Why OT Risk is About to Break Compliance Models – and What Smart Leaders Will Do Next
The Compliance Illusion Passing a cyber audit doesn’t mean your factories will survive the next disruption. In fact, as NIST CSF 2.0, NIS2, and the SEC’s disclosure rules reshape corporate cybersecurity obligations, most manufacturing boards are leaning even harder into frameworks and compliance milestones as proof of security maturity. […]
How to Recalculate CVSS Scores in an OT Context
How to Recalculate CVSS Scores in an OT Context In the IT world, a critical vulnerability with a CVSS score of 9.8 triggers alarms, tickets, executive notifications, and a countdown to remediation. That number carries urgency. It drives board-level discussions, internal SLAs, and compliance audits. But in OT, that same 9.8 might […]
What CFOs Wish CISOs Knew
Roger Hill April 19, 2025 How to Defend OT Security Budgets in a Recession (Without Sounding Like an Alarmist) Let’s get one thing straight — nobody in the boardroom is moved by a list of unpatched CVEs anymore. Not in this economy. In the last 90 days alone, I’ve seen three global manufacturers slash their […]
Why Patching is Not a Panacea in OT Security
Debunking the Dangerous Illusion of Patch-Centric Protection The notion that patching is the foundation of all good cybersecurity hygiene has become almost doctrine.
