Coalition Sends 49 Zero-Day Alerts as Patch Tuesday Hits 569 Flaws
Global -- Coalition sent just 49 Zero-Day Alerts (ZDAs) between May 1 and August 1, 2026, even as Microsoft's July Patch Tuesday swelled to 569 vulnerabilities, and 94% of its policyholders did not receive a single one.
Microsoft's Patch Tuesday count nearly triples in one month
June's Patch Tuesday set a record with 206 vulnerabilities. July's release nearly tripled that to 569. Before Microsoft adopted multi-model AI for vulnerability discovery, it typically shipped around 100 fixes a month. Windows said in July that it would apply AI across security analysis to find flaws earlier and at greater scale, which Coalition says likely contributed to the jump.
Attackers are also moving faster. Anthropic disclosed earlier this year that Mythos could create working exploits for newly discovered vulnerabilities in hours rather than weeks.
