Zero-Day Vulnerability

A zero-day vulnerability refers to a security flaw in software or hardware that is unknown to the vendor and has no official patch at the time of discovery. Exploited by attackers before developers can address it, zero-day vulnerabilities pose a serious threat to organizations, often leading to data breaches, ransomware attacks, and system compromise. Because these flaws are invisible to standard defenses, proactive measures like threat intelligence, behavior-based detection, and rapid incident response are essential to mitigate the risk and minimize potential damage.
