Synack vs. StackHawk

Synack is a continuous penetration testing platform that combines agentic AI with a global network of vetted security researchers to uncover real, exploitable vulnerabilities across the entire attack surface. Most organizations test only a fraction of what matters. Synack closes that coverage gap—using AI to scale discovery and human expertise to validate real risk.

StackHawk is reimagining AppSec for AI-driven development, where applications are built faster than traditional AppSec tools can keep up. Our AppSec Intelligence Platform combines scalable runtime testing with complete attack surface discovery from source code. We integrate directly into development workflows and provide context-aware remediations to developers, enabling teams to find and fix exploitable vulnerabilities before they reach production. With real-time visibility and centralized program intelligence, AppSec teams can prioritize testing and fixing what matters.
