Hand-Picked Comparisons
Acunetix by Invicti (v16.x/17.x)
A high-end DAST engine known for its proprietary 'AcuSensor' IAST technology and 99.98% accuracy. The 2026 version features deep API security testing (GraphQL/REST), native Jenkins/GitHub CI/CD integration, and 'Proof-of-Exploit' reporting. While it is the gold standard for reducing false positives, its high entry price and restrictive target-based licensing make it a difficult choice for small agencies.
Invicti (formerly Netsparker)
The pioneer of proof-based DAST scanning. In 2026, Invicti combines DAST, IAST, and API security with advanced Application Security Posture Management (ASPM). Its proprietary engine safely exploits found vulnerabilities to provide 'Proof of Exploit,' virtually eliminating false positives. While it is the gold standard for large-scale automation, its high entry cost and complex setup for small teams remain significant hurdles.
