Penetration testing employs skilled testers attempting to compromise systems using the methods an attacker would. Testing may be external, internal, or application-focused, and ranges from black box with no information to white box with full access.
Results include identified vulnerabilities and remediation recommendations.

Why it Matters?
Testing scope determines what the report actually establishes, since an external network test says nothing about application vulnerabilities or insider risk. Requesting a vendor's most recent test should include asking what was in scope and whether identified findings were remediated. A clean report on a narrow scope is less informative than a report identifying and closing significant findings on a broad one.
