Tuskira launches Quell to test reachable zero-day exposure before patches land

Quell is a security-operations story that fits the same June 2 pattern as Project Glasswing, Cisco, Workday, and ZeroDrift: agentic AI is being packaged as a control plane for risk. Tuskira says Quell validates whether existing security controls would stop an emerging exploit, identifies defenses being bypassed, and orchestrates compensating control changes before a patch is available. The company launched the capability at the Gartner Security & Risk Management Summit 2026. This is medium-confidence because details come from a Business Wire-distributed company announcement, but the topic is important: the window between disclosure and patching is exactly where AI-assisted attackers and defenders are racing.
