This program represents a paradigm shift from blanket restrictions to identity-based authorization, enabling red teams, bug bounty hunters, and vulnerability researchers to leverage cutting-edge AI without triggering the default safeguards that typically block high-risk cybersecurity activities.
Learning Objectives:
- Understand the purpose, scope, and application process of Anthropic’s Cyber Verification Program
- Master practical workflows for integrating verified Claude access into penetration testing, red teaming, and bug bounty operations
- Implement AI-assisted security testing methodologies using Claude Code, custom skills, and automation frameworks
- Apply responsible disclosure and ethical guardrails when using dual-use AI capabilities
You Should Know:
- Understanding Anthropic’s Cyber Verification Program (CVP): Architecture and Access
Anthropic builds real-time safeguards into its most capable Claude models that block high-risk dual-use activity by default—including vulnerability exploitation, offensive tooling development, and attack-path modeling—even when the intent behind the work is defensive. The Cyber Verification Program creates a narrow, authorized lane for cybersecurity teams whose job is to find flaws before adversaries do.
Eligible categories under the CVP include: authorized penetration testing and red teaming, vulnerability research and disclosure, threat intelligence, and malware analysis. The program is application-based and free, designed specifically for Opus and Sonnet models to enable professionals to continue working on legitimate dual-use tasks with minimal interruptions. Organizations on Zero Data Retention (ZDR) are not currently eligible.
To apply, security professionals must complete the Cyber Use Case Form available through the Claude platform, which involves verification of identity and legitimate security research intent. The verification process may require government-issued ID confirmation to ensure only authorized personnel gain access to restricted capabilities.
Step-by-Step Guide: Applying for and Configuring CVP Access
- Access the Application Portal: Navigate to the Claude platform and locate the Cyber Use Case Form or visit the direct program link at https://claude.com/form/cyber-use-case.
- Complete Identity Verification: Submit a valid government-issued photo ID (passport, driver’s license, or state/province ID) through Anthropic’s verification partner, Persona Identities.
- Submit Use Case Documentation: Clearly articulate your legitimate cybersecurity use case—whether penetration testing, vulnerability research, red teaming, or threat intelligence work.
- Await Approval: Anthropic reviews applications to verify the organization’s or individual’s bona fide security research credentials.
- Configure API Access: Once approved, configure your Claude API or Claude Code environment with the verified credentials to unlock full dual-use reasoning capabilities.
Linux/Windows Commands for API Verification:

- Vulnerability Research and Zero-Day Discovery with Claude Mythos
Anthropic’s restricted frontier model, Claude Mythos (released through Project Glasswing in April 2026), has demonstrated extraordinary vulnerability discovery capabilities. In internal testing, Mythos scanned more than 1,000 codebases and identified 23,019 potential vulnerabilities, with 6,202 rated high or critical. The model surfaced thousands of zero-days across every major operating system and browser. Project Glasswing has since been expanded to approximately 150 organizations across more than 15 countries, extending access to this powerful model designed to find and help fix software vulnerabilities.
For CVP-approved researchers, access to Mythos-class models enables大规模 vulnerability discovery that would be impractical with manual techniques alone. Anthropic’s internal evaluations showed classifiers blocking malicious attempts, while external bug bounties—spanning more than 1,000 hours of testing—found no universal jailbreaks on long-form agentic tasks.
