We investigate 100% of unknowns The CYDEF solution is built around threat hunting (actively searching for new and existing threats) instead of threat intelligence (what we know about previous threats) because past threats are not a good indicator of future threats. Automated cybersecurity solutions can only detect approximately 80% of threats (according to IBM). The remaining 20% tend to be more sophisticated attacks. Human threat hunting is required to detect these threats, which are specifically engineered to bypass automated solutions.
