HackerOne Joins Project Glasswing to Advance Cyber Defense with Frontier AI
HackerOne will apply Claude Mythos 5 to live security infrastructure and share what it learns with the broader security community
SAN FRANCISCO, July 10, 2026 — HackerOne, a global leader in Continuous Threat Exposure Management (CTEM), has joined Project Glasswing, Anthropic's controlled-access program for Claude Mythos 5. HackerOne will share what it learns about applying frontier AI to real-world exposure management to advance cyber defense at scale.
Consistent with Project Glasswing’s mandate, HackerOne is using Mythos to strengthen its defenses. While doing so, HackerOne will benchmark Mythos’ performance in use cases beyond discovery: confirming exploitability with evidence, prioritizing findings by business impact, and generating developer-ready fixes that integrate directly into engineering workflows.
“Attackers are already using frontier AI to find and weaponize vulnerabilities faster than defenders can respond. The only viable answer is for defenders to operate on better models, faster. HackerOne's mission is to empower the world to build a safer internet. Anthropic's is safer software at scale. Same goal, different vantage point. Project Glasswing lets us put the most capable model available to work on our infrastructure and share what we learn across the full CTEM workflow," said Kara Sprague, Chief Executive Officer, HackerOne.
"Building more resilient software requires continuous innovation in how we identify, understand, and remediate risk," said Nidhi Aggarwal, Chief Product Officer, HackerOne. "We are excited to use Claude Mythos to strengthen the security of our internal systems, explore how frontier AI can strengthen every stage of the CTEM workflow from discovery to remediation, and contribute insights that help the security industry move toward continuous cyber defense."
HackerOne's participation in Project Glasswing is scoped exclusively to improve the security of its infrastructure and solutions. Claude Mythos 5 is not being applied to customer programs or external-facing agentic use cases.
