The April launch was tightly controlled — a handful of cybersecurity partners with direct Anthropic relationships. This expansion is a different order of magnitude. One hundred and fifty organizations across 15-plus countries suggests Glasswing is moving from proof-of-concept toward something closer to a structured early-access program. Mythos remains restricted; this isn't a general availability announcement. But the pace — launch in April, Microsoft joining later that month, 150-org expansion by June — signals Anthropic is moving quickly on the cybersecurity vertical. Organizations that applied and didn't make the first wave should check their status.
