Definition
Meaning
An ethical hacker or cybersecurity professional who uses their skills to identify and fix security vulnerabilities, typically with permission.

Linguistics

They are largely synonymous, but 'penetration tester' is a formal job title, while 'white hat' is a broader cultural term emphasizing ethical intent.
No, by definition, white-hat activities are conducted with explicit authorisation from the system owner. Without permission, the same actions would be illegal.
