Vulnerability Assessment and Penetration Testing (VAPT). The tests have different strengths and are often combined to achieve a more complete vulnerability analysis.

 Vulnerability assessment tools discover which vulnerabilities are present, but they do not differentiate between flaws that can be exploited to cause damage and those that cannot. Penetration tests attempt to exploit the vulnerabilities in a system to determine whether unauthorized access or other malicious activity is possible which can be a threat for an application. Penetration tests find exploitable flaws and measure the severity of each.
