Capability · Application security

Providers who deliver application security.

AppSec programs, secure-SDLC uplift, SAST and DAST tuning, and developer security enablement measured by fix rates, not ticket counts.

Request quotes

234 verified providers at one or more levels for application security. Default sort is highest verification level first; ties broken by most-recent record.

Deepest earned coverage in United States (29), India (19), and France (16). Ranking is plan-blind: verification level, contributing record count, and recency are the only signals used. A free-plan L5 provider always outranks a paid-plan L1.
