A vulnerability scan in cybersecurity is a systematic examination of systems, networks, and applications to identify security weaknesses, known as vulnerabilities. These scans use automated tools to detect flaws, misconfigurations, or outdated software that could be exploited by attackers. Conducted regularly, vulnerability scans help organizations maintain their security posture by enabling proactive remediation of identified issues. This process is essential for risk management, compliance with security standards, and safeguarding sensitive data against potential threats.
