The Clock is Running Out On OT Security As You Know It

Why AI-Driven Sabotage Renders Legacy OT Security Obsolete — and the Case for Minimalist Invisibility

Webinar Replay: Mythos vs. Reality — Preventing Industrial Cyberattacks

Featuring Tom Sego, CEO of BlastWave • Aaron Boyd, OT Cybersecurity Penetration Tester, ICS Blitz • Moderated by Cam Cullen, CMO, BlastWave

If you are responsible for an operational technology (OT) network — a water authority, a manufacturing plant, an energy facility, a critical infrastructure operator — there is a specific message in this article that you need to hear before your next board meeting, before your next budget cycle, and arguably before you finish reading this sentence:

"In the era of Mythos, if you are defending, you are losing. It's time to become undiscoverable."

The window between a vulnerability being discovered and that vulnerability being weaponized has collapsed from 10 months to 9 hours. Your patching cycle hasn't changed. That gap is no longer a risk to be managed. It is a structural emergency.

This article is based on a live webinar held June 17, 2025, featuring Tom Sego, CEO of BlastWave, and Aaron Boyd, an OT cybersecurity penetration tester at ICS Blitz, moderated by Cam Cullen, CMO of BlastWave. Aaron has spent his career breaking into — and then helping secure — industrial control systems. What they discussed should be required reading for every asset owner, plant manager, and CISO in the industrial sector.

The webinar replay is on this page. But this article stands alone — because the urgency of what was discussed cannot wait for a convenient viewing window.

What Is Mythos — And Why Did the U.S. Government Pull It From the Market?

Mythos is an AI model developed by Anthropic, specifically engineered to find security vulnerabilities in code. Unlike conventional vulnerability scanners, Mythos doesn't simply flag known CVEs or obvious misconfigurations. It daisy-chains vulnerabilities — following complex, multi-step exploit paths through layered software stacks in ways no human security researcher could replicate at scale.

One documented exploit chain discovered by Mythos ran 30 vulnerabilities deep. Thirty cascading failures, each one enabling the next, opening a path that no single security audit would have caught.

Recognizing the dual-use danger of this capability, Anthropic did not release Mythos publicly. Instead, they launched Project Glasswing, a controlled access program that gave leading cybersecurity vendors — companies like Microsoft, Palo Alto Networks, and CrowdStrike — early access to Mythos so they could identify and patch vulnerabilities in their own products before adversaries developed comparable tools.

The results were immediate and significant. Within the Project Glasswing rollout, Mythos identified 1,500 findings in open-source projects alone — and only 97 had been patched. That is a 6% remediation rate. The patch Tuesday that followed Microsoft's access to Mythos was, by all accounts, unusually large.

And then, as Tom Sego described in the webinar, the U.S. government classified Mythos as an export control weapon and pulled it from availability — a recognition of just how powerful this capability is.

Let that sink in. A security research tool was treated by the federal government as a weapons system.

Now ask yourself: how long before adversaries — nation-states, organized criminal groups, and eventually less sophisticated actors who can simply ask an AI what to do — develop something comparable?

The answer, based on the trajectory of AI capability, is: not long. And when they do, your OT network needs to be invisible to them.

The OT Security Crisis That Already Existed Before Mythos

Here is the uncomfortable truth that Aaron Boyd opens with every client engagement: OT insecurity is not the result of negligence. It is the result of architectural inheritance.

Industrial control systems — PLCs, DCS platforms, RTUs, safety instrumented systems — were designed decades ago with primary engineering priorities being availability, determinism, and safety. Cybersecurity was not a realistic threat vector. Physical isolation was assumed. Only trusted engineers were expected to ever interface with these systems.

Authentication was minimal. Encryption was absent by design — you cannot introduce decryption latency into a real-time control signal. Logging was either sparse or nonexistent. And patching was simply not a thing, because taking an OT asset offline risks production downtime, safety incidents, and potential regulatory violations.

Over time, business requirements changed. Remote monitoring, vendor access, IT/OT convergence — all of these introduced connectivity into environments that were never architecturally designed to handle it. The result, as Aaron describes it, is a profound mismatch between how OT systems were built and the threat landscape they now face.

The Complexity Tax

A typical OT stack today might include real-time operating systems, embedded Linux distributions, proprietary application logic, open-source libraries, middleware, protocol converters, and remote management services. Many of these components are enabled by default — asset owners must actively turn them off if they don't use them, and many don't even know they're running.

This is what the webinar calls the Complexity Tax: the thousands of unnecessary code paths and open services accumulating in traditional industrial gateways and security appliances. Each additional layer introduces dependencies, configuration requirements, and potential failure modes. From a penetration testing perspective, vulnerabilities frequently exist not in the core control logic but in ancillary services — web interfaces, file transfer mechanisms, login components, third-party libraries included for convenience and never disabled.

Asset owners often have no complete picture of what software is running on their devices, let alone whether those components are actively maintained. As Aaron puts it: "You can't protect what you don't know. You can't defend what you can't see."

The numbers confirm the severity. Average remediation timelines in enterprise IT environments already exceed 200 days. In OT environments, with their operational constraints, the timelines are longer still. Tom Sego's term for patches that will realistically never be applied in OT: "never patches" — and Aaron confirmed the term with a laugh, citing Windows XP and Windows 7 systems still running in active OT deployments.

The Failure of the "God Box"

The webinar surfaces a critical architectural failure point that the broader security industry rarely acknowledges: the "God Box" problem. This is the practice of centralizing security into a single, feature-rich, multi-service appliance — a bloated OS running dozens of services simultaneously, positioned as the single guardian of the network.

The logic seems sound. One box, one pane of glass, everything managed centrally. But Mythos exposes why this is precisely the wrong architecture for the current threat environment. A multi-service OS is a high-value, high-complexity target for automated exploit tools. Every additional service running on that box is another attack surface. Every open port is another opportunity. And if that single system is protecting both OT and IT simultaneously, a successful compromise has catastrophic blast radius.

The answer is not a smarter God Box. The answer is structural minimalism: turn off every non-essential service, remove the OS-level bloat, and give AI-powered reconnaissance tools nothing to find.

The Complexity Tax in Practice

Aaron's testimony from the field is direct. When you conduct a typical OT audit and ask whether a site has remote access, corporate personnel will often say no — because policy doesn't allow it. But policy and reality are frequently different things. If you are not physically on-site validating your network, you cannot know for certain what connectivity exists.

"You'd be surprised how many reports I deliver and they're like, 'We had no idea this was possible,'" Aaron notes. "That's why you trust but verify."

This is the OT security environment into which Mythos — and AI-powered attacks more broadly — have now arrived.

AI Does Not Create the Weakness. It Demolishes the Buffer.

One of the most important distinctions Aaron draws is this: AI does not fundamentally alter the underlying vulnerabilities in OT environments. What it does is destroy the two defenses that OT operators have historically relied upon without realizing it: obscurity and time.

Obscurity meant that attacking OT required deep protocol knowledge, specialized tooling, and domain expertise that was genuinely rare. The limited documentation, the proprietary interfaces, the specialized training requirements — all of these functioned as a friction layer that kept the barrier to meaningful OT exploitation high.

Time meant that even when vulnerabilities were known, there was a meaningful window — historically around 10 months — between discovery and a functional exploit being deployed at scale. That window allowed organizations to assess, plan, test, and patch.

AI eliminates both.

With AI-assisted tooling, the specialized knowledge required to understand OT protocols, reverse-engineer firmware, and navigate proprietary systems is no longer a meaningful barrier. As Aaron puts it: "AI lowers the barrier to entry and increases the scale at which attacks can be conducted." A report by the UK's National Computer Security Centre documented this dynamic — AI helps nation-state actors and experienced hackers somewhat, but it helps less sophisticated actors dramatically. The script kiddie of five years ago can now simply ask an AI what to do next.

And on the time dimension: AI has compressed the vulnerability-to-exploit timeline from 10 months to 9 hours. This is documented, measured data — not a projection.

Reaction is no longer a viable security strategy. By the time you know about the vulnerability, the exploit window may already be closing.

Meanwhile, the defensive response timeline has not changed. Average patch deployment still runs around 60 days in enterprise environments. In OT it runs longer. The asymmetry is structural, and it is only widening.

The Time Asymmetry Problem — And Why Defensive AI Cannot Close the Gap in OT

The cybersecurity industry's current answer to AI-powered attacks is more AI on the defensive side — faster detection, automated response, "AI vs. AI." In IT environments, this logic has some merit. A compromised endpoint can be quarantined. A suspicious process can be terminated. A network segment can be isolated. These actions carry costs, but those costs are recoverable.

In OT environments, automated responses carry a categorically different risk profile. Quarantining an OT asset can halt production. Isolating a network segment can interrupt safety systems. Taking a device offline without understanding the full chain of operational dependencies can create the very incident you were trying to prevent. As Tom Sego describes it, OT asset owners get a 

As Tom Sego describes it, OT asset owners get a "deer in the headlights" look when automated defensive responses are proposed — because they know that an automated action against the wrong target could trigger a safety incident with second and third-order consequences that are worse than the attack itself.

This means the AI-speed attack surface cannot be met with AI-speed defensive automation in OT. Attackers move at machine speed. Defenders must move at human-reviewed, risk-assessed, change-controlled speed. That asymmetry is not a gap to be closed with better tooling. It is a structural feature of OT environments.

The only viable response is not to fight the attacker within the attack surface. It is to eliminate the attack surface entirely.

The Mythos Chain of Pain: Why Patch-Dependent Security Strategies Are Failing

Even if patching were fast — and it isn't — Mythos-class vulnerability discovery creates a problem that patching alone cannot solve.

Consider a single vulnerability in an open-source protocol library. Four different vendors in your OT environment may use that library. To remediate, all four must patch. But vendor A cannot patch until vendor B patches, because they share a communication protocol. And one vendor may have four separate products deployed in your environment, all using the same protocol stack — meaning they must all be upgraded simultaneously in what Tom calls a "flash upgrade", because upgrading one while others remain unpatched breaks the communication chain.

A flash upgrade in OT requires taking down your entire infrastructure simultaneously. It requires extensive pre-testing. It requires coordination across multiple vendors. And it may require regulatory sign-off as well.

This is the Mythos chain of pain. It is not a hypothetical. It is the operational reality every asset owner faces when a deep vulnerability chain is discovered in their environment.

When Mythos-class tools reach adversaries, they will identify these chains faster than you can remediate them. The question is not whether you will face a Mythos-class vulnerability chain. The question is whether your network will be visible to the tools that find them.

The Three Defenses That Would Have Stopped Every Attack in BlastWave's Hackopedia

BlastWave maintains a resource called the Hackopedia — an analysis of 23 of the most significant and well-documented OT cyberattacks in recent history. The finding that stands out is not complicated:

Fewer than two of the 23 attacks involved sophisticated zero-day exploits. The vast majority succeeded through one of three failure modes: exposed systems with known CVEs, stolen or default credentials, or lateral movement through flat, unsegmented networks.

If three specific controls had been in place across all 23 networks, none of the attacks would have succeeded.

Control 1: Network Cloaking — From Visible to Vanished

If an attacker cannot find your network, they cannot attack it. This is the difference between a firewall and a cloaking device. A firewall is a shield — it sits in front of a visible, known target and attempts to block every attack, indefinitely. A cloaked network does not appear as a target at all.

The mechanism behind this is cryptographic "knocking" — a technique that ensures your ports don't even exist to any scanner, human or AI-powered, until an authorized cryptographic credential has been presented. Unauthenticated reconnaissance tools return nothing, because there is nothing to return. The network is not filtered. It is absent.

Aaron Boyd describes the impact of network cloaking from direct personal experience. He was engaged for a before-and-after penetration test at a client site — standard work: identify vulnerabilities, deliver the report, return a few months later to retest after remediation. When he came back, something had fundamentally changed.

"I genuinely have never banged my head on a desk as hard as I did. I had no idea what I was looking at on the network. I couldn't reach anything to actually compromise it. I would have had to chain at least 11 things together."

The client had deployed BlastShield. Adversaries — unlike penetration testers given unlimited time — move on to softer targets when faced with that level of complexity.

As Tom Sego frames it: the Enterprise has shields. The Klingons have a cloaking device. You can hit shields time and time again until you find a hole. You cannot hit what you cannot see.

Control 2: Micro-Segmentation — Shrinking the Blast Radius

Even where an attacker gains initial access — through a phishing campaign, a compromised credential, or a supply chain vector — micro-segmentation limits what they can do with it. Lateral movement, the technique that turns a single compromised endpoint into a network-wide incident, requires traversal between devices. Micro-segmentation restricts what each device can reach, and what can reach it.

In OT environments, where east-west traffic between PLCs, HMIs, and SCADA systems often travels on flat networks with minimal access controls, micro-segmentation is one of the highest-leverage defensive investments available. It also directly addresses supply chain attacks — a compromised vendor component that enters the network finds itself isolated, unable to propagate.

Control 3: Passwordless MFA — Removing the Credential as an Attack Surface

Between 80 and 90% of cyberattacks involve some form of credential theft or harvesting. Phishing, credential stuffing, default password exploitation — all are accelerated dramatically by AI, which can now generate convincing, socially engineered phishing content at industrial scale. The broken English of phishing emails from five years ago is gone. AI writes better phishing than most humans do.

Passwordless MFA eliminates the credential as an attack surface. There is no password to steal. Authentication is cryptographic, tied to a physical device or biometric factor, and cannot be harvested through any phishing campaign.

Critically, BlastShield delivers passwordless MFA to devices that cannot run agents — PLCs, HMIs, RTUs, SCADA systems, DCS platforms, safety instrumented systems. Every device in the OT environment gets cryptographic authentication, not just the ones capable of supporting endpoint software.

Introducing BlastShield: Structural Resilience Over Reactive Complexity

BlastWave built BlastShield from first principles for the OT security environment. Not adapted from an IT product. Not retrofitted to accommodate OT constraints. Built from the ground up on the principle that in OT, the answer to AI-powered speed isn't a faster alert — it's a smaller attack surface.

The BlastShield architecture is deliberately minimalist. A "Secure by Design" approach that turns off all non-essential services and removes the OS-level complexity that Mythos-class tools exploit. Where the God Box centralizes risk, BlastShield distributes and eliminates it.

BlastShield delivers all four critical capabilities in a single, integrated deployment:

• Network Cloaking — cryptographic knocking that makes your infrastructure invisible and non-discoverable to unauthenticated users and automated scanning tools
• Micro-Segmentation — software-defined segmentation that limits lateral movement and reduces blast radius, deployable without the complexity and cost of VLAN-based firewall architectures
• Passwordless MFA — cryptographic authentication delivered to every OT device, including agentless PLCs, HMIs, RTUs, and safety instrumented systems
• Secure Remote Access — session-recorded, encrypted remote access that replaces insecure tools like TeamViewer and VNC, with built-in remote desktop performance that is over 2.2 times faster than competing solutions

The Deployment Advantage

BlastShield deploys approximately 20 times faster than a traditional industrial firewall solution. It costs approximately one-quarter as much and requires approximately half the ongoing administrative overhead. Combined, that is approximately 160 times the operational advantage versus a firewall-based approach — in a real-world, measurable sense, not a marketing one.

The software appliance runs on a VM, commodity x86 hardware, or in containers and Kubernetes clusters. It sits upstream of industrial switches and imposes Layer 2 isolation downstream on any managed switch infrastructure.

A Track Record That Speaks for Itself

BlastShield has been deployed across 5,000 locations in 21 countries, accumulating over half a billion device hours of protection. In that history, there has been not a single successful breach.

That track record includes NSA red team exercises, U.S. Army purple team engagements, and independent penetration testers — including Aaron Boyd of ICS Blitz, who reached out to BlastWave after encountering a BlastShield-protected network he could not penetrate, and needed to understand what he was looking at.

BlastWave does not claim BlastShield is unhackable — nothing is. What the data shows is that adversaries encountering a BlastShield-protected network face a cost-of-attack high enough that they move on to softer targets. In a world where AI has made soft targets infinitely easier to find, that calculus matters enormously.

The Mythos vs. Reality eBook: Required Reading for Industrial Security Leaders

It is free. It is detailed. And if you are responsible for an OT environment, it may be the most important document you read this year. Download it here →

The Cost of Getting This Wrong

The financial comparison between OT breaches and IT breaches is not widely understood outside the sector — and it should be.

IBM's Cost of a Data Breach report puts the average IT breach at approximately $4.4 million. That is a serious number. It is not the number that applies to OT.

When Jaguar Land Rover suffered an OT-targeted cyberattack last September, the company did not manufacture a single vehicle. The estimated cost: $2.5 billion — roughly 570 times the average IT breach cost.

The NotPetya attack, which disrupted OT operations across 76 ports worldwide, carried an estimated total cost of $10 billion.

OT environments are simultaneously easier to attack than modern IT infrastructure — because of legacy architecture, patching constraints, and the absence of endpoint security tooling — and dramatically more expensive when breached, because production loss, safety incidents, and regulatory consequences compound the damage in ways a data breach does not.

Ransomware targeting OT has nearly doubled year-over-year, according to Dragos's 9th Annual OT/ICS Cybersecurity Report. The adversaries know the math. The question is whether the defenders do.

The First-Principles Answer to a First-Principles Problem

In second grade, you learned that if X equals zero, 100X is also zero. The first-principles logic of OT security in the age of AI is exactly this.

If AI can automate reconnaissance 100 times faster — but your network is invisible to reconnaissance — the AI advantage equals zero. If AI can generate credential-harvesting campaigns at industrial scale — but there are no passwords to harvest — the AI advantage equals zero. If AI can identify lateral movement paths across flat networks — but your network is micro-segmented — the AI advantage equals zero.

The answer is not to outrun the AI. The answer is to remove the target.

Frequently Asked Questions

OT Security, AI-Powered Threats, and BlastShield: What Asset Owners Need to Know

What is Mythos, and why does it matter for OT security?

Mythos is an AI model developed by Anthropic specifically designed to discover security vulnerabilities in software code. Unlike conventional vulnerability scanners, Mythos can follow complex, multi-step exploit chains through layered software stacks — a process called vulnerability daisy-chaining. In one documented case, Mythos traced an exploit chain 30 vulnerabilities deep, identifying a path that no human security researcher would realistically find. For OT environments, which rely on layered legacy software stacks and have minimal patching capacity, this capability represents a categorical shift in the threat landscape. The U.S. government subsequently classified Mythos as an export control weapon, a recognition of its potential as an offensive tool if adversary actors develop comparable capabilities.

What is Project Glasswing, and who has access to Mythos?

Project Glasswing is Anthropic's controlled access program for Mythos. Rather than releasing the model publicly, Anthropic provided early access to a select group of trusted cybersecurity vendors — including Microsoft, Palo Alto Networks, and CrowdStrike — so they could apply Mythos to their own codebases and remediate vulnerabilities before the technology became more broadly available. Within the Project Glasswing rollout, Mythos identified 1,500 findings in open-source projects, of which only 97 had been patched at the time of reporting. The patch Tuesday release following Microsoft's access to Mythos was notably large, suggesting significant vulnerability discovery within their internal systems.

Why is patching OT systems so much harder than patching IT systems?

OT systems are designed around availability, not security. They operate continuously and cannot be taken offline without risking production downtime, safety incidents, or regulatory compliance violations. Patches must undergo extensive testing to ensure they do not interfere with real-time performance, deterministic behavior, or OEM maintenance agreements. In many cases patches do not exist at all — vendors have discontinued support for legacy platforms still in active OT deployment. Even where patches are available, the remediation process frequently requires coordinating upgrades across multiple vendors simultaneously — a "flash upgrade" that requires taking down the entire infrastructure. Average remediation timelines in enterprise IT environments exceed 200 days; OT timelines are longer. Tom Sego refers to patches that will realistically never be applied in OT as "never patches" — Aaron Boyd of ICS Blitz confirmed the term with a laugh, citing Windows XP and Windows 7 systems still running in active industrial deployments.

What is the "Complexity Tax" in OT security?

The Complexity Tax refers to the accumulated attack surface created by decades of incremental software layering in OT environments. A typical OT stack includes real-time operating systems, embedded Linux distributions, proprietary application logic, open-source libraries, middleware, protocol converters, and remote management services — many enabled by default and unknown to the asset owner. Each additional layer introduces new dependencies, configuration requirements, and potential failure modes. AI-powered tools like Mythos are specifically effective at exploiting this complexity, because they can traverse thousands of code paths and correlate findings across multiple software versions and vendors simultaneously, identifying exploit chains that no human auditor would find.

What is the "God Box" problem in OT security?

The "God Box" refers to the common practice of centralizing security into a single, multi-service appliance — one bloated OS running dozens of services, positioned as the single guardian of the network. While this approach simplifies management, it creates a high-value, high-complexity target for automated exploit tools. Mythos-class AI can analyze the attack surface of a God Box and identify exploit chains through its many services and open ports. The risk compounds significantly when a single God Box is used to protect both OT and IT simultaneously, as a successful compromise has catastrophic blast radius across both environments. The architectural answer is structural minimalism: turn off every non-essential service, reduce code paths, and give AI-powered reconnaissance nothing to exploit.

What is network cloaking, and how is it different from a firewall?

A firewall is a defensive perimeter — it sits in front of a visible, known network and attempts to block unauthorized traffic. The network remains discoverable; adversaries can see it, probe it, and attempt to find gaps in the firewall rules. Network cloaking makes the network itself non-discoverable and non-addressable to unauthenticated users and devices. The mechanism is cryptographic "knocking" — ports do not exist to any scanner until an authorized cryptographic credential has been presented. Unauthenticated AI-powered reconnaissance tools return nothing, because there is nothing to return. The analogy from the webinar: a firewall is the Enterprise's shields — you can hit them repeatedly until you find a hole. Network cloaking is the Klingon cloaking device — you cannot attack what you cannot see.

What is passwordless MFA, and why does it matter more in OT than in IT?

Passwordless multi-factor authentication replaces the traditional username-password credential pair with a cryptographic authentication mechanism tied to a physical device or biometric factor. Because there is no password, there is nothing to steal through phishing, credential stuffing, or harvesting — which collectively account for 80 to 90% of all successful cyberattacks. In OT environments, passwordless MFA carries special significance because many critical devices — PLCs, HMIs, RTUs, SCADA systems, DCS platforms, and safety instrumented systems — cannot run endpoint agent software. BlastShield delivers passwordless MFA to these agentless devices, extending cryptographic authentication across the full OT environment rather than just the devices that can support software agents.

What is micro-segmentation, and what does it protect against in OT networks?

Micro-segmentation restricts communication pathways between individual devices, limiting what each device can reach and be reached by. In a traditional flat OT network, a single compromised device can traverse freely across the network — a technique called lateral movement. Micro-segmentation reduces the blast radius of any individual compromise by constraining how far an attacker can move once inside. It is particularly relevant to supply chain attacks, where a compromised vendor component enters a customer environment and attempts to propagate. BlastShield delivers software-defined micro-segmentation that can be deployed and modified without the complexity and cost associated with VLAN-based firewall architectures.

Can AI-powered defensive tools close the gap against AI-powered attacks in OT?

In IT environments, AI-powered defensive tools can provide meaningful response acceleration — automated quarantine, process termination, and network isolation can operate near the speed of AI-powered attacks. In OT environments, this parity does not exist. Automated responses carry the risk of halting production, interrupting safety systems, or triggering operational incidents more damaging than the attack they are intended to stop. OT security strategies cannot rely on automated defensive responses without full understanding of the operational consequences of each potential action. This structural asymmetry — attackers at machine speed, defenders at human-validated speed — means the most effective OT defensive strategy is not response acceleration but exposure elimination: making the network invisible, the credentials unstealable, and the attack surface non-traversable.

What is BlastShield, and what does it include?

BlastShield is BlastWave's integrated OT security platform, purpose-built for industrial environments. It delivers four capabilities in a single deployment: network cloaking (cryptographic knocking that makes infrastructure non-discoverable to unauthenticated users and automated tools), micro-segmentation (software-defined device isolation to limit lateral movement), passwordless MFA (cryptographic authentication across all OT devices, including agentless PLCs and HMIs), and secure remote access (session-recorded, encrypted remote desktop access that replaces insecure tools like TeamViewer and VNC). BlastShield deploys as a software appliance on a VM, commodity x86 hardware, or in containers and Kubernetes clusters, upstream of industrial switches. It has been deployed across 5,000 locations in 21 countries, accumulating over half a billion device hours without a single successful breach.

How quickly can BlastShield be deployed compared to a traditional industrial firewall?

BlastShield deploys approximately 20 times faster than a traditional industrial firewall solution, costs approximately one-quarter as much, and requires approximately half the ongoing administrative overhead — a combined operational advantage of approximately 160 times versus a firewall-based approach. Traditional firewall deployments in OT involve extensive VLAN configuration, access control list management, and change management overhead; any topology change requires firewall rule updates that can be time-consuming and error-prone. BlastShield's software-defined architecture allows segmentation policies to be updated without the complexity and downtime risk of firewall reconfiguration.

How do I get started assessing my OT network's exposure to AI-powered threats?

BlastWave recommends beginning with a direct conversation about your current OT network architecture, connectivity model, and patching posture. The first step is understanding where your actual exposure exists — which systems are discoverable, which credentials could be harvested, and which networks are flat enough to enable lateral movement.
