The Vendor Runs the Border

Anthropic has expanded its Cyber Verification Program, giving qualifying security professionals access to Claude Opus 5.5, Sonnet 5.5 and Mythos 5.1 with reduced blocking classifiers for authorized defensive work.^[1]

Reuters reports that Glasswing partners found at least 129,000 verified software vulnerabilities between April and July. Anthropic’s own open-source scans found another 5,500 between April and October. More than 33,000 of the disclosed verified findings were rated critical or high. These are company-reported findings, not a count of presently vulnerable production systems.^[2][3]

The three access levels are Defense, Red Team and Specialized. Anthropic says Specialized applicants receive an in-depth review with the U.S. government; existing Glasswing members transition without reapproval for current models. The usage policy still applies, and grants can be narrowed or withdrawn.^[1]

Here’s the inference: the company is selling a tool and deciding who can operate its most capable version. Controlled access may be responsible distribution. It is also private governance, with government-assisted review for the Specialized tier.

The border here is a metaphor for vendor-controlled access. The permission slip is quite real.
