Claude Security enterprise scans move to Claude Mythos 5 public beta
Anthropic has moved Claude Security, its enterprise vulnerability scanner, onto Claude Mythos 5, described in reporting as its most cyber-capable model. The upgrade is in public beta for Claude Enterprise customers who can switch on frontier-level scanning without separate direct API access to the model. According to multiple outlets, the tool analyzes codebases for flaws, provides severity ratings with CWE classifications, suggests patches, and supports automated scanning of GitHub repositories. Anthropic says it is working with providers to embed Mythos 5 in third-party defensive tools and is deploying $35 million in credits for open-source security work. The productized path could reduce custom LLM pipeline work for security teams, though reporting frames availability as Enterprise-only beta, leaving broader rollout timing unclear.
Claude Security enterprise scans move to Claude Mythos 5 public beta
Anthropic has moved its most cyber-capable model into a product security teams can switch on themselves. Claude Security scans now run on Claude Mythos 5, in public beta for Claude Enterprise customers.
Key takeaway

Why it matters
Security architects and DevOps leaders may gain a vendor-supported path to LLM-assisted static analysis with rated findings and remediation hints instead of building bespoke audit pipelines.
Limits and uncertainties
Reporting describes Mythos 5 in Claude Security as a public beta limited to Claude Enterprise customers.
Third-party provider embeds for Mythos 5 are announced but specific partners and integration timelines are not detailed in the packet.
The $35 million open-source security credit program is referenced only in truncated excerpts, so full eligibility and scope are not fully specified here.
Practical implications
Claude Enterprise security teams can trial Claude Security on Mythos 5 rather than wiring direct frontier model APIs into custom code-audit workflows.
Development teams scanning GitHub repositories may evaluate built-in CWE-rated findings and patch suggestions as an added layer in existing review or CI processes.
