Threatspy

ThreatSpy is an Autonomous Application & API Security platform designed to help organizations discover, validate, prioritize, and remediate security vulnerabilities faster. Traditional security tools often generate large volumes of findings, leaving security and engineering teams to manually determine what is exploitable and what should be fixed first. ThreatSpy helps eliminate that noise by combining Dynamic Application Security Testing (DAST), API Security Testing, exploitability validation, reachability-based prioritization, and AI-assisted security review into a single workflow.
