Industrial Cybersecurity Insider

Craig sits down with Wil Klusovsky, a 26-year cybersecurity veteran and CRO at viLogics, to break down why asset visibility and exposure management are the foundation of any solid OT security strategy.
From the myth of the air-gapped shop floor to the real-world math behind quantifying cyber risk in dollars and cents, Will and Craig explore how manufacturers can move beyond fear-based selling, bridge the gap between IT and operations, and build programmatic cybersecurity that protects both production uptime and the bottom line.
They discuss how to frame cyber risk as business risk, why compensating controls and context matter more than raw vulnerability numbers, and why the CISO's real job is "chief inside selling officer."

Is the Purdue Model outdated, or simply misunderstood? In this episode, Dino sits down with Ken Kully (Rockwell Automation) for a candid, practitioner-level conversation about what the Purdue Model still gets right.
They discuss where it falls short in modern environments, and why “IT/OT convergence” remains more of a people-and-process challenge than a technology problem.
They break down the reality on the plant floor: long-lived legacy systems, inconsistent architectures across sites, limited maintenance windows, and the operational consequences of downtime.
The discussion also tackles the everyday friction points: MFA, shared operator accounts, unmanaged vendor laptops, and remote access “surprises”, and why you can’t improve OT security posture without a trustworthy asset inventory and segmentation that keeps systems “in their lane.”
Chapters:
(00:00:00) Intro + why this Purdue conversation matters now
(00:01:00) Ken’s background: from process environments to OT cyber delivery readiness
(00:04:00) The big question: has the Purdue Model outlived its usefulness?
(00:07:00) Framework vs. strict blueprint: “Purdue enough” in real plants
(00:09:00) IT/OT convergence: why it’s a people + process problem (not tech)
(00:12:00) The “silver tsunami” and why security UX fails on the plant floor
(00:15:30) MFA, shared logins, and why “security gets in the way” still shows up
(00:18:00) Legacy reality: Windows 98/7 boxes, vendor lock-in, and downtime economics
(00:21:00) Discovery first: diagrams, configs, and why documentation is always missing
(00:23:30) Purdue as a map: brokering traffic, one-up/one-down, and the “3.5” DMZ
(00:26:00) When devices try to “escape the box”: unexpected outbound comms + exposure risk
(00:28:30) Vendor/OEM access: the unmanaged laptop problem in OT
(00:32:00) Asset inventory as the unlock: you can’t defend what you don’t know exists
(00:34:00) Why IT often won’t “crawl the plant,” and what that means operationally
(00:36:30) Scale problem: 30 plants, 30 realities—standardize globally, execute locally
(00:38:30) The SI/OEM “third leg”: why trusted integrators are key to sustainable OT security
(00:40:30) Closing + crossover: continuing the discussion on Ken’s OT After Hours podcast

Dino and Jim break down a major shift in the cyber threat landscape: federal agencies obtaining legal authority to enter private networks to hunt down state-sponsored malware, and what that signals for industrial organizations.
They discuss why critical infrastructure and supply chains are prime targets, how “soft targets” in OT and building automation get exploited, and why many companies still lack visibility into what’s happening on the plant floor.
The conversation zooms in on real-world exposure points, especially unmanaged vendor remote access and end-of-life equipment, and closes with practical themes for leadership.
Stop assuming “IT has it covered”
Define measurable OT security outcomes
Start taking steps that make disruption harder and detection faster.

Chapters:
(00:00:00) Why identity, trust, and vendor access are breaking down in modern plants
(00:01:00) The episode’s trigger: government-led operations to remove malware from private networks
(00:03:00) “Machete scanning” and why IT-style tactics can disrupt OT operations
(00:05:00) The real target set: critical infrastructure, supply chains, and smaller utilities with limited resources
(00:08:00) Collateral damage and how cyber “weapons” trickle down to criminal ransomware
(00:13:00) Why OT is still a soft target: visibility gaps, unpatched systems, and weak segmentation
(00:14:00) Remote access everywhere: OEM/SI pathways, unknown identities, and lack of governance
(00:20:00) The logging gap: what IT sees vs. what OT can’t see (and why that matters for incident response)
(00:24:00) Building automation and facilities systems as weak links attackers love
(00:26:00) Executive accountability: what boards should be measuring after breaches (and why progress stalls)

A real-world case study shows how a single phishing email led to credential and MFA compromise, creating an urgent question for any industrial organization: Did the attacker reach the OT environment?
Dino and Jim walk through how OT visibility, secure remote access controls, and continuous monitoring enabled rapid validation of what happened. They were able to prove the breach did not impact control systems and avoid an expensive, safety-driven shutdown of a continuous manufacturing process.
The episode connects technical controls to executive outcomes, including resilience, duty of care, and the financial reality that “not knowing” can be as costly as an actual compromise.
Chapters:
(00:00:00) Why continuous manufacturing makes “abundance of caution” shutdowns so costly
(00:01:00) What “OT continuous monitoring” means and why it matters in real incidents
(00:03:00) Safety and connected environments: why “it can go boom” changes the stakes
(00:05:00) Baselines: defining “normal” so abnormal behavior is actionable
(00:07:00) Incident story: phishing email leads to credential and MFA compromise
(00:09:00) What the team validated: tracing access and confirming OT was not impacted
(00:10:00) Lessons from Colonial Pipeline: inability to validate can force shutdowns
(00:11:00) OT reality check: Windows assets, HMIs, historians, and engineering workstations
(00:13:00) Secure OT remote access: why VPN-only access is not sufficient
(00:16:00) The payoff: avoided downtime, avoided product loss, and avoided disruption
(00:19:00) Executive view: duty of care, liability, compliance, and protecting enterprise value
(00:23:00) The “air gap” myth and why defense-in-depth is the only practical path

In this episode, Dino and LuRae address why system integrators, OEMs, and ecosystem partners are often a manufacturer’s most underused cybersecurity resource.
Dino explains why many IT leaders lack real visibility into the plant floor, what it takes to operationalize OT security beyond “checking the box,” and why asset inventory is the first practical step toward protecting control systems.
The conversation also covers the realities of remote access after COVID, the need for governance measures such as change control and auditing, and why manufacturers should build real partner relationships rather than purely transactional vendor engagements.
Chapters:
(00:00:00) OT security requires time inside the plant, not an “ivory tower” view
(00:01:00) Introducing Dino and the topic: partners as a cybersecurity asset
(00:02:00) Why OT assets get excluded from cybersecurity strategy
(00:03:00) The real opportunity: system integrators and OEMs already in the plant
(00:05:00) Getting started: identify who’s working in each facility
(00:08:00) Step one: accurate OT asset inventory and visibility
(00:10:00) Remote access: detect, audit, and control what partners are doing
(00:12:00) “Compliance” vs. operational reality on the plant floor
(00:16:00) Resourcing reality: why most teams cannot self-perform OT security
(00:20:00) Final advice: budget, ROI of downtime, and act before the incident
