Overview
Claude Security is **Anthropic's product line for enterprise-grade security scenarios**, optimized for network defense, critical infrastructure protection, security research, and incident response. The core model is the **Claude Mythos series**—a specialized branch of Claude trained for cybersecurity capabilities, running parallel to the mainline Claude Opus/Sonnet series.
**Two major milestones in 2026**:
**❶ 2026/4/7 Project Glasswing launched**: Anthropic announced an investment of **$100 million in model usage credits**, partnering with leading security organizations (CrowdStrike, Microsoft, Palo Alto Networks, Trellix, etc.) to establish 'Project Glasswing', with the goal of **protecting critical software security in the AI era**. Why the name Glasswing (Glasswing Butterfly)? It symbolizes 'AI making security defense transparent'—as attackers use AI to accelerate attacks, defenders must also use AI to respond.
**❷ 2026/6/9 Claude Mythos 5 officially released**: Officially claimed to be **the most capable frontier model for cybersecurity on the market**, covering:
- **Vulnerability detection and code audit**: Identifies complex vulnerability patterns, with 40%+ higher accuracy than general models
- **Threat intelligence analysis**: Processes massive security logs, correlates events, and generates incident reports
- **Malicious code analysis**: Deobfuscation, anti-debugging code understanding, and behavioral analysis
- **Red and blue team assistance**: Supports red team penetration testing and blue team defense response
- **Compliance audit**: Automated mapping of SOC 2, ISO 27001, NIST, and other compliance requirements
**Project Glasswing now covers approximately 150 organizations across 15 countries**—including critical infrastructure protection, network defense research, and government agency collaborations. This is Anthropic's largest-scale deployment of its 'AI for the benefit of humanity' strategy in the security domain.
**Product form**: Not a standard API or subscription service, but a **customized solution for enterprise customers**—accessed through the Claude Enterprise commercial channel, with dedicated professional security consulting teams and exclusive access to the Mythos 5 model. Suitable for large enterprises, government agencies, and critical infrastructure operators (power/finance/healthcare/transportation).

Pricing
**Customized solution for enterprise customers**, with no publicly available standard pricing. Accessed through the **Claude Enterprise commercial channel**: requires communication with the Anthropic Sales team to discuss specific needs, including Mythos 5 model access credits, professional consulting services, and Project Glasswing ecosystem resources. **Existing Project Glasswing partners can upgrade directly to Mythos 5** (no need to re-sign contracts). Suitable for enterprises and organizations with an annual security budget of $1 million+.
Summary
Claude Security is **Anthropic's flagship product in enterprise-grade cybersecurity**—integrating the **Claude Mythos 5 model + Project Glasswing ecosystem + $100 million investment + deployment across 150 organizations in 15 countries** as a four-in-one solution, making it the most comprehensive 'AI-driven network defense' solution on the market. **If you are a CISO of a large enterprise, head of information security at a government agency, or operator of critical infrastructure**, Claude Security is a candidate solution that must be evaluated; for **small and medium-sized enterprises**, the threshold is relatively high, and they can focus on AI security products from Project Glasswing ecosystem partners like CrowdStrike, Microsoft, and Palo Alto (which may all be using Mythos 5 at their core). With Claude Security, Anthropic has made clear its strategic judgment that 'security is the first battlefield for AI applications'.
