Invicti (formerly Netsparker) dramatically reduces your risk of being attacked. Automated application security testing that scales like none other. Your team's security problems grow faster than your staff. Security testing automation should be integrated into every step in your SDLC. Automate security tasks to save your team hundreds of hours every month. Identify the critical vulnerabilities and then assign them to remediation. Whether you are running an AppSec, DevOps or DevSecOps program, help security and development teams to get ahead of their workloads. It's difficult to prove that you are doing everything possible to reduce your company's risk without full visibility into your apps, vulnerabilities and remediation efforts. You can find all web assets, even those that have been forgotten or stolen. Our unique dynamic + interactive (DAST+ IAST) scanning method allows you to scan the corners of your apps in a way that other tools cannot.

Invicti Web + API, previously known as Acunetix, is a DAST solution for discovering, testing, prioritizing, and managing vulnerabilities across web applications and APIs. The platform combines automated runtime scanning with AI-assisted security capabilities intended to bring automated testing closer to the depth of manual penetration testing. It can automatically discover web applications, APIs, shadow assets, unlinked pages, and undocumented endpoints across an organization's attack surface. Invicti detects more than 7,000 security issues, including OWASP Top 10, OWASP API Top 10, and business logic vulnerabilities. Testing capabilities cover single-page and JavaScript-heavy applications, LLM-powered services, authenticated user flows, multi-step application processes, and REST, GraphQL, and SOAP APIs. AI-driven risk scoring analyzes more than 200 signals, while runtime reachability, exploitability, and business context help teams determine which vulnerabilities should receive priority. Proof-based validation is designed to reduce false positives by confirming whether detected vulnerabilities are actually exploitable, with Invicti reporting 99.98% confirmation accuracy for exploitable vulnerabilities. DAST-to-SAST correlation can map vulnerabilities to source code, while AI-powered remediation provides developers with targeted guidance and automated validation retests fixes after remediation. Integrations with CI/CD, ticketing, development, and security systems help organizations incorporate continuous web and API security testing into existing software development workflows.
