Grey-Box Testing

Testing with partial knowledge of the system — the middle ground between a black-box outsider's view and a white-box walkthrough of the source. Used where you want realistic attack simulation without a full code audit on every pass.

Partial-Access Testing · Realistic Simulation

What it is

Grey-box testing gives the tester some internal context — a user account, partial documentation, limited API access — similar to what a malicious insider or a partially-compromised credential would have. It finds more than black-box testing without the time and cost of a full source-code review.

How it works

  1. 01
    Agree on the access level

    What partial knowledge or access the tester gets — a standard user role, limited docs — matched to the realistic threat you're modeling.

  2. 02
    Test from that vantage point

    Attempting privilege escalation, lateral movement, and logic flaws that only surface once you're partly inside.

  3. 03
    Compare against the black-box baseline

    Findings are contextualized against what a fully external attacker could and couldn't reach.

Benefits

  • Finds privilege-escalation and insider-style risks black-box testing misses
  • Faster and cheaper than a full white-box source review
  • Matches the realistic threat of a compromised credential or malicious insider

Frequently asked

What access does the tester actually get?

Agreed with you during scoping — typically a standard user account and partial documentation, calibrated to the specific insider or compromised-credential scenario you want tested.

Not sure this is the right fit yet?

A scope call is a lower-commitment way to find out before anything gets built.
