The models' case: Best overall balance for a typical mid-market security team needing a human-led web, API, mobile, cloud, or network audit quickly. The models' main caveat: Annual credits and tier-gated reporting features make it less attractive for a small one-off engagement. The strongest alternative is BreachLock — Provides an optimal balance of cost predictability and compliance utility by blending continuous automated scanning with in-house certified manual.
