GREY BOX TESTING
Grey box testing: deeper results in less time
With limited access, we test like a logged-in user or insider and find what others miss.
What is grey box penetration testing?
Grey box penetration testing is a security test where testers get limited information, such as user accounts, roles or basic architecture details. It simulates a logged-in user, partner or insider, allowing deeper testing of authorisation, business logic and internal systems in less time than a black box test.
Most damage happens after login.
Grey box testing checks what a user, partner or insider could do with normal access.
