AI-enabled vulnerability discovery has upended a core assumption of cyber risk: that the most dangerous weaknesses in critical networks are difficult and time-consuming to find. For business leaders, this development is a material shift in enterprise risk, not a technology trend. Perfect prevention is not an achievable standard, but leaders who act now to narrow the gap through AI-augmented scanning, disciplined configuration management, and well-rehearsed response plans can materially reduce both exposure and impact.
Anthropic's Claude Mythos Preview is the first model to demonstrate this at scale, but the capability is structural, not proprietary, and similar models will follow within months. Businesses are now in a race to recalibrate strategy, budget, and preparedness against this new reality, and to find and fix critical vulnerabilities before adversaries find them for you.
A call for focused urgency
It’s not surprising that AI is supercharging vulnerability discovery: exposing the weaknesses in our code and configurations at a speed, depth, and scale that far outstrips human ability. What distinguishes this generation of models is their ability to autonomously chain multiple vulnerabilities into working exploits — a task that previously required elite human operators. This means that vulnerabilities once considered “safe” now can be weaponized.
This is not about one model. Similar capabilities are emerging across frontier AI labs, making this a structural market shift. New models with similar capabilities will emerge faster than companies can prepare. Business leaders should confront an essential truth: there will be vulnerabilities in your environment that neither you nor your management team are aware of, and some will be actively exploitable before they can be fixed.
Your security posture is a leadership obligation
Collaborative, ecosystem responses like Anthropic’s technical consortium, Project Glasswing, are an important starting point but can’t secure every business and network. Glasswing includes roughly 50 organizations. Most enterprises sit outside that perimeter and must build their own defensive posture, including the capacity to apply patches at an order of magnitude greater than before. Otherwise, as widely used platforms are hardened, adversaries will redirect toward the enterprise-specific targets only you can secure. That makes your security posture a leadership obligation.
The place to start is by leveraging new capabilities. AI-assisted defensive scanning is the most significant capability defenders have gained in a decade. It’s also the most credible answer to the standard-of-care question leaders will soon face. Every week organizations continue operating at human speed while attackers leverage AI only widens the asymmetry. And as these tools become broadly available, choosing not to use them will become harder to defend.
Your business doesn’t need direct access to a specific frontier model to act. Focus investment where two questions intersect: what in your environment would be indefensible at machine speed, and what, if breached, would cause catastrophic harm? Then close the loop. Finding vulnerabilities faster only matters if you fix or contain them.
Six steps business leaders can direct now
The leadership choice
This new generation of AI capability is a wake-up call, but not a reason to despair. Most cyber risk comes from longstanding weaknesses and misaligned incentives, not novel threats. We now have tools powerful enough to address those weaknesses at scale, if we choose to act.
We have crossed the Rubicon. The response is known, and the tools exist. Leaders have a short time to mobilize resources to find and fix vulnerabilities at a greater scale than ever before. Success will belong to leadership teams that acknowledge their organization’s exposure, prioritize closing the most material gaps quickly, build strong governance for new agentic capabilities, and meet the legal standard of care.
How PwC can help
This shift demands strategic clarity at the board level, operational acceleration across the enterprise, and confidence that AI itself is governed responsibly. The six steps above require execution across strategy, technology, and governance simultaneously. We work with leadership teams to:
Quantify the gap. We conduct AI-accelerated vulnerability assessments that give boards an honest picture of exploitable exposure, not a compliance score.
Close it at speed. We help stand up Vulnerability Operations, agent-driven code review, and automated containment—so defensive response matches the new threat timeline.
Govern the response. We provide the governance and assurance frameworks that regulators, auditors, and boards will expect as AI-powered security tools become standard.
