Tuskira Launches Quell to Mitigate Zero-Day Vulnerabilities

Tuskira has introduced Quell, an AI-driven tool designed to address zero-day vulnerabilities at the Gartner Security & Risk Management Summit 2026. Quell identifies reachable zero-days in an organization’s environment and assesses whether existing security controls can prevent exploitation. The tool has demonstrated effectiveness, helping organizations reduce breachable exposure by up to 99%. In a case study, it transformed 12.3 million raw findings into just 0.46% actionable risk within weeks. Quell utilizes a Security Context Graph and a digital twin to continuously monitor and respond to threats. It also incorporates live threat intelligence to map exploit preconditions and orchestrate compensating controls without waiting for patches. This approach is crucial as the speed of exploit development has drastically increased, making traditional patching methods insufficient.

Key Points: • Tuskira launched Quell to help organizations manage zero-day vulnerabilities effectively. • Quell can reduce breachable exposure by up to 99% and triage time from weeks to minutes. • The tool uses AI to assess existing controls and orchestrate immediate compensating actions.
