What is the difference between Vulnerability Assessment and Penetration Testing?

Vulnerability AssessmentPenetration Testing
Identifies and lists known vulnerabilities, usually via automated scanningActively exploits vulnerabilities to demonstrate real-world impact
Broad coverage across many systemsFocused, often manual, deep dive on specific targets
Produces a prioritized list of weaknessesProduces a narrative of what an attacker could actually achieve
Typically faster and cheaperMore time-intensive and requires skilled testers

Most mature security programs run vulnerability assessments frequently, such as monthly, and schedule a full penetration test less often, such as annually or after major changes, to validate that the identified weaknesses are actually exploitable in practice.

Which activity actively exploits vulnerabilities to prove impact?
Which activity typically has broader, automated coverage?
