DAST / web vulnerability scanning · Alternatives
The Best Acunetix Alternatives in 2026
Acunetix is a capable automated DAST scanner for finding common web vulnerabilities at scale. Teams look for alternatives when they want a lower cost, tighter CI/CD and developer workflows, or testing that goes beyond signature-based scanning into real exploitation and authorization logic. Here are six alternatives and where each one fits.
Why teams look for Acunetix alternatives
- ›Acunetix pricing is commercial and quote-based, which can be high for smaller teams
- ›As a DAST scanner it detects known patterns but does not exploit or chain vulnerabilities
- ›Authorization, IDOR, and business-logic flaws are largely out of a DAST scanner's scope
- ›You want testing owned by developers inside pull requests and pipelines
- ›You want the depth of a penetration test, not only automated scanning
6 best Acunetix alternatives
Penetrify
Editor's pickAn autonomous AI penetration testing platform that attacks running web applications and APIs like an adversary — mapping the attack surface, testing authentication and authorization, and chaining findings into multi-step exploits. It returns a structured report in minutes and runs on every deploy via CI/CD.
Invicti
An enterprise DAST/IAST platform (formerly Netsparker) from the same market as Acunetix, known for proof-based scanning that confirms vulnerabilities to reduce false positives.
Burp Suite
The industry-standard manual web security testing toolkit, with an intercepting proxy and (in paid editions) an automated scanner.
OWASP ZAP
A free, open-source DAST proxy and scanner maintained by the OWASP community.
StackHawk
A developer-first DAST tool that runs in CI/CD, driven by API specs, with findings surfaced in pull requests.
Detectify
An external attack surface management and DAST platform combining asset discovery with a crowdsourced ethical-hacker payload library.
DAST Scanner vs. Autonomous Pentester
Acunetix, Invicti, ZAP, and StackHawk are all DAST scanners — they send payloads at a running application and match responses against known vulnerability patterns. They differ in price, false-positive handling, and how well they fit a developer pipeline, but they share the same fundamental limit: they detect, they do not exploit.
Penetrify is an autonomous penetration tester. It reasons about the application, attempts exploitation, and chains findings — so it catches authorization flaws, IDOR, and business-logic bugs that DAST scanners flag weakly or miss entirely.
Matching the Tool to the Goal
If you want a direct DAST replacement with verified findings, Invicti. For free scanning, OWASP ZAP. For developer-owned CI scanning, StackHawk. For manual depth, Burp Suite. For continuous external surface coverage, Detectify.
If the real reason you are leaving Acunetix is that scanning alone is not enough, Penetrify's exploitation-driven approach is the upgrade in depth — at $100/month, with CI/CD integration.
The verdict
For a like-for-like Acunetix replacement, Invicti is the closest enterprise DAST; OWASP ZAP is the free option, and StackHawk the developer-pipeline option. But if you want testing that proves exploitability — covering authorization and business-logic flaws that no DAST scanner reliably catches — Penetrify's autonomous penetration testing is the more meaningful step up, starting at $100/month.
Frequently asked questions
What is a cheaper alternative to Acunetix?
OWASP ZAP is a free, open-source alternative for DAST scanning, and StackHawk offers a free tier plus affordable paid plans for developer-owned scanning in CI/CD. Penetrify provides autonomous penetration testing — deeper than DAST — starting at $100/month.
What does Penetrify do that Acunetix does not?
Acunetix is a DAST scanner that detects known vulnerability patterns. Penetrify actively exploits and chains vulnerabilities, proving real attack paths, and tests authorization, IDOR, and business-logic flaws that DAST scanners generally miss. It is a penetration test rather than a scan.
Is Invicti the same as Acunetix?
Invicti (formerly Netsparker) and Acunetix are separate products in the same automated DAST market and are commonly compared. Both focus on automated web vulnerability scanning; Invicti emphasizes proof-based scanning to reduce false positives. Neither performs adversarial exploitation the way an autonomous pentester like Penetrify does.
