Anthropic has shared its Mythos AI-powered cybersecurity tool with 150 additional organizations, according to a report from Cybersecurity Dive, bringing the total number of partners in Project Glasswing to well over 200. The latest cohort includes operators of critical infrastructure, a category that spans power grids, water systems, and financial networks. The move signals that Anthropic is treating Mythos as a core part of its external safety strategy rather than a limited pilot program.
What Mythos Does
Mythos is a specialized security evaluation tool designed to identify vulnerabilities in software systems at scale. Earlier phases of Project Glasswing demonstrated the tool's reach: a preview deployment uncovered more than 10,000 zero-day vulnerabilities across partner systems. For critical infrastructure operators, those kinds of findings carry real weight. A zero-day in a power grid management system or a water treatment control network presents a very different risk profile than the same flaw in a consumer application.
Key Facts
- 150 new organizations have received access to Mythos through Project Glasswing
- The expanded cohort includes critical infrastructure operators
- Total Glasswing partners now exceed 200 organizations
- Mythos uses Claude-based AI to identify software vulnerabilities at scale
- Earlier deployments found more than 10,000 zero-day vulnerabilities in partner systems
The expansion also follows Anthropic's decision to allow partners to share Mythos findings more openly within the program. That change matters for infrastructure operators in particular, since vulnerabilities discovered in one sector often have parallels in adjacent systems. Coordinated disclosure across a larger group could accelerate patching timelines across multiple industries simultaneously.
Expanding access to tools like Mythos to critical infrastructure operators reflects a broader recognition that AI can play a meaningful role in proactive defense, not just threat detection after the fact.Cybersecurity Dive
Growing Global Footprint
Project Glasswing has moved quickly since its initial launch. Recent expansions brought in NATO and Samsung, alongside energy and grid operators across multiple countries. The program now spans a wide range of sectors, from defense-adjacent organizations to consumer electronics manufacturers. Anthropic has also extended Mythos access internationally, with deployments reaching critical infrastructure in more than 15 nations.
Anthropic has positioned Project Glasswing as part of its broader safety mission, arguing that putting powerful vulnerability-detection capabilities into the hands of defenders, before adversaries exploit the same flaws, is a net benefit to overall security. That argument is easier to make when the partners include organizations responsible for systems that millions of people depend on daily. Whether the program's pace of expansion introduces its own coordination challenges remains a fair question as the partner list continues to grow.
For now, the addition of 150 organizations in a single tranche suggests Anthropic has streamlined its onboarding process considerably. The company has not publicly detailed the vetting criteria applied to new partners, though access to a tool capable of finding thousands of zero-days in production systems would reasonably require some baseline of trustworthiness on the receiving end. As the program scales further, transparency around those criteria will likely become a topic of interest for policymakers and security researchers alike.
