Anthropic Claude Mythos Preview: The More Capable AI Becomes, the More Security It Needs

The Claude Mythos Preview matters for every enterprise. Frontier models raise the ceiling for both offense and defense. Our job is to make sure defenders hold the advantage. That is what we have always done. That is what we do today.

Today, CrowdStrike is a founding member of Project Glasswing. Anthropic builds the model. CrowdStrike secures AI where it executes. That’s the division of labor the industry needs.

CrowdStrike evaluated the security implications of this model and brings something no other coalition member has: sensor-level visibility across every endpoint in the enterprise. A trillion events a day. 280+ tracked adversary groups. 1,800+ AI applications already discovered across customer environments. This data is what makes AI governance enforceable.

CrowdStrike’s assessment of Mythos Preview confirms Frontier AI capabilities compound when paired with real-world threat intelligence, enterprise-scale visibility, and machine-speed enforcement. 

Why This Matters

Frontier AI is not a single product. It is a new category of enterprise infrastructure.

Claude Code is changing how developers build software. AI agents are reshaping how enterprises automate operations. Anthropic’s Mythos Preview expands the reasoning, planning, and execution capabilities of AI agents. They all touch the endpoint — where data is accessed, decisions are made, value is delivered, and risk is born.

New models are also where opportunity is the largest. The same frontier models that expand the attack surface give defenders a capability advantage that did not exist a year ago: discovering vulnerabilities, detecting threats, and responding to incidents faster than ever before.

Adversaries will continue to look to use the same capabilities for malicious purposes. CrowdStrike's 2026 Global Threat Report found an 89% increase in attacks by adversaries using AI year-over-year. The use of AI for vulnerability discovery and exploit development is accelerating on both sides.

The Division of Labor

Model safety is the builder’s responsibility. Deployment governance is ours.

Anthropic develops frontier models under its Responsible Scaling Policy, evaluating capabilities before release and red-teaming for dangerous behaviors.

This work addresses what the model can do. It does not address what happens when the model runs inside an enterprise with access to customer data, financial systems, and thousands of users deploying the model without governance. When an AI agent connects to a CRM, queries a database, or triggers a workflow, it’s not a model safety question. That is a deployment governance question. 

CrowdStrike secures AI where it executes. Discovery of every AI agent in the environment. Visibility into what those agents access and what they do. Protection of sensitive data flowing through AI workflows. Runtime protection for AI agents connecting to enterprise systems.

What CrowdStrike Brings

A frontier model is the engine. Data is the fuel. The platform is how you operationalize it.

CrowdStrike’s role in this coalition is grounded in capabilities no other member has:

• Threat Intelligence: 280+ tracked adversary groups. Real-world attack data that informs how frontier AI is weaponized and how to defend against it. This intelligence determines which vulnerabilities matter most: not just what exists, but what adversaries are actively targeting right now.
• AI Detection and Response (AIDR): Secures all agents — homegrown, third-party, and local — at runtime and discovers and governs AI applications and agents across the enterprise. Shadow AI, sanctioned AI, every tool running on every endpoint and beyond. Much of it deployed without security team approval. You cannot govern what you cannot see.
• CrowdStrike Falcon® Data Security: Prevents sensitive enterprise data from leaving through AI workflows. Visibility and enforcement at the data layer. As organizations point frontier models at proprietary code and sensitive data, the risk of unintended exposure increases. Falcon Data Security enforces boundaries.
• AgentWorks: Enables enterprises to build agents for security and more, with all the governance and guardrails built in. This infrastructure allows enterprises safe access to frontier models, ensuring that all of the audit and controls exist on Day One. 

These capabilities are built on the CrowdStrike Falcon® platform, already deployed across the enterprises that run the world.

The Regulatory Clock

The EU AI Act’s next phase takes effect August 2, 2026. Automated audit trails. Cybersecurity requirements for every AI system classified as high-risk. Incident reporting obligations. Penalties up to 3% of global revenue.

Governance is no longer a best practice. It is a legal requirement. Enterprises deploying frontier AI need the technical means to comply. CrowdStrike delivers the platform that makes it possible.

A Familiar Bet

We did not build the cloud. We made it enterprise-safe. This discipline created CrowdStrike and protected the organizations that moved their most critical workloads to AWS, Azure, Google Cloud, and OCI.

AI is the same bet. AI is bigger. And this time, security is at the table from the start.

The enterprises that move fastest on AI will be the ones that can govern it. The ones that cannot will slow down.

Frontier models coupled with Falcon make CrowdStrike the best defender in the industry because it is already on the device where AI executes, where the data flows, and where the adversary strikes. 

CrowdStrike is how enterprises stay protected. We stop breaches.
