Trail of Bits Security Review Pricing in 2026
Trail of Bits publishes no prices. It says each review uses “a team sized to your threat model rather than a fixed template”, and the sample report on its services page states scope as engineers and person-weeks of effort. A quote from Trail of Bits is therefore a team size multiplied by a duration, and that is the number to ask for.

Reading a Trail of Bits quote
Trail of Bits shows what a report contains on its services page, with a sample cover reading “Engineers 4, Level of effort 10 person-weeks”. That is an illustration of the format, not a typical engagement, but it tells you how the work is sized: by people and weeks. Ask any quote to state both, so you can compare it on a per-person-week basis with other research firms and with market day rates.
Before a formal scope, Trail of Bits offers a free hour of technical office hours: a working session with one of its engineers on a specific problem, which it says involves “no pitch and no sales engineer”.
Where Trail of Bits sits: research-led consulting
Reviews sized per threat model and staffed in person-weeks are the consulting shape in our PTaaS vs traditional consulting comparison, not a credit or subscription model. For what a compliance-driven pentest needs to include, which is a different job from a code or protocol review, see what’s included in a pentest.
