Synack vs. APPCHECK

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.

AppCheck is a Dynamic Application Security Testing (DAST) and network vulnerability testing solution, developed and supported by experienced penetration testers. We approach security testing as a hacker would, leveraging multiple proprietary crawling engines to analyse target behaviour across both modern and traditional technologies, including Single Page Applications (SPAs), APIs, and complex authentication flows such as SSO, 2FA, and TOTP.
