Acunetix is a web vulnerability scanner built for teams that want automated DAST without a steep learning curve. It detects over 7,000 vulnerability types with 99.98% accuracy through proof-based scanning.

Part of the Invicti family, Acunetix targets small and mid-sized organizations while Invicti handles enterprise accounts. Thousands of companies use it, including Cisco, NASA, and American Express.
According to the OWASP Foundation, automated dynamic testing is a recommended practice for identifying runtime vulnerabilities that static analysis alone misses.
What are Acunetix’s key features?
| Feature | Details |
|---|---|
| Vulnerability checks | 7,000+ types including OWASP Top 10, out-of-band |
| Accuracy | 99.98% with proof-based scanning |
| Scanning engine | C++ based, 2-4 hour average scan time |
| IAST support | AcuSensor agent for .NET, Java, PHP, Node.js |
| Risk scoring | Predictive AI model using 220+ parameters, 83% minimum confidence |
| API scanning | REST, SOAP, GraphQL |
| SPA support | Full JavaScript rendering for React, Angular, Vue |
| Concurrent scans | Unlimited parallel scans |
| Update cadence | Monthly releases with auto-update |
I run authenticated dynamic scans against logged-in user sessions using the Business Logic Recorder, which lets me reach pages that anonymous crawlers cannot. The scanner does API security testing (black-box) against REST, SOAP, and GraphQL endpoints by ingesting OpenAPI/Swagger specs or recorded traffic. SQL injection / XSS probing uses payload mutation across discovered parameters, and the proof-based engine confirms each finding by safely exploiting it before I see the alert.

Predictive Risk Scoring
Acunetix uses a machine learning model that analyzes over 220 parameters to estimate vulnerability risk before scanning begins. The model requires a minimum 83% confidence threshold before assigning a risk score.
Your most exposed targets get scanned first.

Note: Acunetix and Invicti share the same proof-based scanning engine. Acunetix is the simpler, more affordable option aimed at SMBs. If you outgrow it, migration to Invicti's enterprise platform is straightforward.
Reporting
Acunetix ships with multiple report templates covering both technical and compliance needs:
- Standard reports: Affected Items, Developer, Executive Summary, Quick
- Compliance reports: CWE, HIPAA, ISO 27001, NIST SP 800-53, OWASP Top 10, PCI DSS, Sarbanes-Oxley, STIG DISA, WASC
- Export formats: CSV, JSON, XML
What does Acunetix integrate with?
There is also a REST API for custom integrations. For broader context, see the DAST tools landscape and the enterprise sibling Invicti .
How do I get started with Acunetix?
How to use Acunetix
After install, my typical workflow is: add a target FQDN, attach an authentication profile (form, basic, or recorded macro), pick a scan profile (Full, High Risk, XSS, or SQL Injection), and launch. Average scan time runs 2-4 hours per target depending on application size.
I trigger scans from the UI for ad-hoc work and from the REST API for CI/CD pipelines. The CLI is not the primary entry point โ Acunetix is API-first for automation. A typical pipeline call posts to /api/v1/scans with a target ID and profile, polls for status, and pulls findings as JSON.
Triage happens in the dashboard. Each finding ships with proof-of-exploit, severity, and remediation guidance, and selected issues push straight to Jira, GitHub, or Azure Boards via the integration layer. The Business Logic Recorder is the right answer when a workflow needs multi-step macros that the crawler cannot follow on its own.
Licensing
Acunetix uses target-based pricing per FQDN. Minimum purchase is 5 targets on a 2-year subscription with annual payment. No free tier or community edition exists.
What are Acunetix’s limitations?
Acunetix does not offer a free tier. The 5-target minimum and 2-year commitment may not suit organizations that want to test a single application first.
Authenticated scanning of highly complex SPAs can still require manual macro recording. For open-source alternatives, consider ZAP or Nuclei .
As a DAST tool , it focuses on web applications and APIs. For teams comparing testing approaches, see SAST vs DAST vs IAST .
Acunetix does not replace static analysis or manual penetration testing for business logic flaws.
What are alternatives to Acunetix?
If Acunetix does not fit, four alternatives cover most exit paths.
Invicti is the enterprise sibling โ same proof-based engine, multi-team RBAC, and ASPM via the Kondukto acquisition. Pick it when you outgrow Acunetix’s per-FQDN pricing or need to manage thousands of apps in one console.
Burp Suite Professional is the standard manual-testing toolkit. Pick it when a hands-on pentester drives the work and the BApp Store extensions matter more than guided scans. PortSwigger publishes Burp Suite Pro at $475 per user as of 2026.
ZAP is the most capable free DAST. Pick it when budget is the constraint and your team has the security expertise to tune the configuration.
Detectify leans on a 400+ ethical-hacker crowdsource program plus EASM. Pick it when external attack surface coverage matters as much as deep app scanning.
StackHawk wraps ZAP for CI/CD. Pick it when developer-owned pipeline scans matter more than IAST or proof-based confirmation.
