Zero-Day Threat Intelligence

3 briefings•0 vulnerability reports

Zero-day vulnerabilities are security flaws exploited before the vendor releases a patch, making them among the most dangerous threats in cybersecurity. Nation-state actors and advanced criminal groups prize zero-days for their ability to bypass existing defenses. defend.network monitors zero-day disclosures from vendor advisories, CISA alerts, and threat intelligence feeds, prioritizing those with confirmed active exploitation.
