Invicti Web + API, formerly Acunetix, is a dynamic application security testing platform designed to automate vulnerability discovery, validation, prioritization, and remediation workflows for web applications and APIs. The product builds on more than 20 years of Acunetix DAST technology while incorporating AI, code-to-runtime correlation, and vulnerability management capabilities. Invicti can automatically identify web applications, APIs, shadow assets, unlinked pages, and undocumented endpoints across code, traffic, and runtime environments. Its scanning engine detects more than 7,000 security issues, including vulnerabilities from the OWASP Top 10 and OWASP API Top 10 as well as business logic flaws. The platform supports modern single-page applications, JavaScript-heavy websites, LLM-powered services, role-based authentication scenarios, complex multi-step workflows, and stateful API testing. API security testing covers REST, GraphQL, and SOAP services while maintaining context across requests. Invicti uses AI-driven risk scoring based on more than 200 signals together with runtime reachability, exploitability, and business context to help teams prioritize security findings. Proof-based validation confirms exploitable vulnerabilities to reduce false positives, with Invicti reporting 99.98% confirmation accuracy for exploitable findings. DAST-to-SAST correlation connects runtime vulnerabilities with corresponding source code, while AI-powered remediation delivers developer-oriented fix guidance and automated validation can retest applications after changes are implemented. Invicti also provides agentic penetration testing capabilities that coordinate specialized AI agents, adapt attack plans to application behavior, investigate chained and contextual vulnerabilities, and validate findings using its proof-based techniques.
