Acunetix Alternatives 2026: What to Switch To (and Why Invicti Is Not One)

If you are searching for Acunetix alternatives, start with a fact most lists skip: Acunetix is now Invicti Web + API. That is not a rumour. It is the banner running across acunetix.com’s own homepage. So before you compare anything, it is worth being precise about what you are leaving, because the answer to “what should I switch to” depends entirely on which part of Acunetix stopped working for you.

This guide routes by reason rather than ranking. It also corrects two naming changes that nearly every competing list still gets wrong, and one supposed deadline that does not appear in the vendor’s own documentation.

The short answer

• The per-target bill is the problem - look at Probely, Detectify, or Astra, which bill per target or per month at published rates instead of per FQDN on a multi-year commitment.
• You want to stop paying entirely - ZAP by Checkmarx is free under Apache 2.0 and covers the same core detection classes, at the cost of more false-positive triage.
• You want scanning in the pipeline - StackHawk publishes $10/user/month and has repositioned around CI and AI coding agents rather than the security team’s console.
• You want depth, not coverage - Burp Suite Professional at $499/user/year, plus human testing for anything involving business logic.
• You have outgrown the SMB tier - the Invicti Platform, Rapid7 InsightAppSec, HCL AppScan, or Qualys WAS. Note that the first of those is the same vendor you are leaving.
• A regulator is asking - no scanner answers this. UAE frameworks want independent human-led testing, and the scanner is an input to your own process, not the evidence.

First, the thing the other lists get wrong

Search “best Acunetix alternatives” and you will find published lists ranking Invicti as the number one alternative. Consider what that recommends.

Acunetix launched in 2005. In 2018 it combined with Netsparker to form Invicti Security. The two products have shared a proof-based scanning engine ever since - the same technology that attempts to confirm an exploit rather than merely flag a pattern. Invicti took a $625 million growth investment led by Summit Partners in October 2021, with earlier backer Turn/River Capital remaining a significant shareholder, and it acquired ASPM vendor Kondukto in 2025 to round out the platform.

What actually separates the two products is packaging, not detection:

So moving from Acunetix to Invicti is a tier change inside one vendor’s catalogue. It may well be the right call if you have outgrown fifty targets and want SAST and ASPM in the same console. But it is an upgrade path, not a competitive alternative, and a list that puts it at number one is not doing the comparison it claims to be doing. Our Acunetix vs Invicti breakdown covers the split in detail.

Why are you actually leaving?

This is the question that determines everything. Four reasons account for nearly every switch.

Reason 1: the quote came back wrong

Acunetix licenses per FQDN with a five-target minimum, typically on a multi-year subscription billed annually. The trap is that a fully qualified domain name is not an application. One product that resolves at www, api, staging, and admin is four targets. Teams scope five, then find the real estate is twenty, and the renewal arrives at four times the number they budgeted.

Reported figures put entry pricing near $7,000 per year for five targets, roughly $1,400 per target, falling toward $740 per target at fifty. The per-unit rate improves with volume, which is exactly why the vendor is relaxed about subdomain sprawl and you should not be. The full quote-driver breakdown is in our Acunetix pricing guide.

Where to go instead:

• Detectify - published pricing from around $90 per month billed annually, with the attack-surface discovery angle built in rather than bolted on. Strong fit if your estate is genuinely sprawling and you would rather pay for discovery than guess at target counts.
• Astra - the most transparent pricing in this set. The DAST scanner runs roughly $69 to $499 per month, and Astra also sells pentest-as-a-service at around $1,999 per target per year for the autonomous tier and $5,999 for the expert tier that adds manual testing. Useful when you want scanner and human testing on one invoice.
• Probely - quote-based rather than published, but built around per-target scanning with a developer-facing API, and frequently the closest like-for-like swap for an Acunetix workload.

Reason 2: you would rather not pay at all

ZAP remains the strongest free option and genuinely covers the same core OWASP Top 10 detection classes - intercepting proxy, active and passive scanners, scripted automation, CI integration. The trade has not changed: you absorb more false-positive triage and a rougher interface in exchange for a zero licence cost.

What has changed is the name, and this is the second thing most lists get wrong. ZAP left OWASP in 2023, moving to the Linux Foundation’s Software Security Project to secure sustainable funding. Then in September 2024, Checkmarx hired all three core project leads - Simon Bennetts, Rick Mitchell, and Ricardo Pereira - and the project was rebranded ZAP by Checkmarx. Today the zaproxy.org homepage carries Checkmarx branding and makes no mention of OWASP anywhere.

For most users nothing practical changed. It is still free, still Apache 2.0, still a community GitHub project anyone can contribute to, and the core team still governs it independently. But if vendor neutrality was part of why you chose it, be aware that its paid maintainers now work for a commercial DAST vendor. Write “OWASP ZAP” in a 2026 tool evaluation and you are quoting a name that has been retired for two years. Our ZAP comparison and Burp vs ZAP head-to-head cover the capability trade in depth.

Reason 3: it does not fit how your team ships

Acunetix is built around a security team’s scanning console. If your actual need is a check that runs on every pull request, the console model fights you.

StackHawk is the clearest answer here, and it has moved further than most lists record. It publishes $10 per user per month for its Wingman tier with unlimited applications and 50 scans per user per month, with a custom-priced Scale tier above it for unlimited agentic scans, attack surface discovery, SSO, and program reporting. There is no permanent free tier, only a 14-day trial.

The notable 2026 shift is positioning: StackHawk now markets explicitly around AI coding agents, naming Claude Code, Cursor, GitHub Copilot, Codex, and Antigravity as supported surfaces. Lists that still describe it as “CI-native DAST” are describing the 2023 product. If your developers are shipping code through an agent, the scanner that meets them there is a different proposition from one that emails the security team a PDF. See our StackHawk vs Invicti comparison for the direct trade.

Reason 4: it keeps missing things that matter

This is the reason no alternative scanner fixes, and it deserves more honesty than tool lists usually give it.

DAST scanners are pattern engines with a crawler. They are good at injection classes, misconfigurations, outdated components, and missing headers. They are structurally poor at anything requiring an understanding of what the application is supposed to do: broken object-level authorization, multi-step workflow abuse, price and quantity manipulation, tenant isolation failures, privilege escalation through legitimate features. Swapping Acunetix for Probely does not move that needle, because the limitation is the category, not the vendor.

Two things do move it:

• Burp Suite Professional at $499 per user per year - not an automated scanner replacement, but the tool a human uses to test what automation cannot reach. Pro now bundles Burp AI at no extra cost. See our Burp Suite pricing guide.
• Human-led testing, which is the only thing that finds logic flaws reliably and the only thing regulators accept as primary evidence.

Our automated vs manual penetration testing guide draws the line between the two in practice.

About that migration deadline

A claim circulating in reseller and partner content says Acunetix on-premises deployments face a mandatory migration to the Invicti Platform effective 29 April 2026. Before you build a project plan around it, check where it comes from.

Here is what holds up:

• Confirmed: Acunetix has been rebranded Invicti Web + API. The vendor says so on its own homepage.
• Confirmed: Invicti publishes documented migration guidance for moving from Acunetix on-premises to the Invicti Platform, including what carries over and what does not.
• Confirmed: Acunetix Premium release notes show routine vulnerability-database updates continuing through mid-2026. The product is receiving maintenance, not winding down.
• Not confirmed: the deadline itself. Invicti’s own migration documentation describes the path without publishing a mandatory cut-off date. The specific date appears in third-party reseller material.

This matters because a forced-migration date is exactly the kind of thing that turns a renewal negotiation. If your on-premises deployment is the reason you are shopping, get the end-of-support position from your account manager in writing rather than from a partner blog. It may well be real. It is just not something the vendor has published, and the difference is worth a single email.

What none of these change

If the reason a scanner is on your budget line at all is a UAE compliance obligation, changing scanners does not move your position, because no UAE regulator certifies scanning tools.

NESA and the wider NCA framework, CBUAE for banks, DFSA in the DIFC, ADHICS in Abu Dhabi healthcare, and PCI DSS for anyone handling card data all ask for broadly the same evidence: independent penetration testing with a scoped statement of work, demonstrable tester independence, severity-rated findings with a methodology reference, and retest evidence closing the loop. None of them names a tool.

The practical consequence is liberating. You can change scanners on purely commercial grounds - price model, contract length, CI fit - without touching your regulatory posture. The inverse is also true: buying a more expensive scanner does not advance your compliance position by a single control. What advances it is independent penetration testing that produces a regulator-facing report, with the scanner feeding your own vulnerability management process in between.

Our UAE penetration testing cost guide covers what that engagement actually runs.

Verdict by situation

• Your subdomain count blew up the quote - Probely for the closest swap, Detectify if discovery is the real gap, Astra if you want published pricing and human testing bundled.
• You want to stop paying for scanning - ZAP by Checkmarx, accepting the triage overhead. Budget engineering time, not licence cost.
• Your developers, not your security team, need the results - StackHawk at $10/user/month, especially if AI coding agents are already in the workflow.
• You are finding bugs the scanner should have caught - the problem is the category. Add human testing rather than swapping vendors.
• You outgrew the 5-to-50 target band - the Invicti Platform is the honest recommendation, with Rapid7, HCL AppScan, and Qualys WAS as the genuine competitive set. Just do not call it leaving Acunetix.
• A regulator or an enterprise customer is asking - no scanner on this page answers that. Book the independent test.

How pentest.ae fits

We do not resell scanners, which is why this page can say that Invicti is not an Acunetix alternative and that a cheaper scanner will not find your authorization flaws.

What we do is the part the tooling cannot reach: web application penetration testing that tests business logic and authorization the way an attacker does, API security testing for the endpoints crawlers reach last, and a Guardian retainer that keeps coverage continuous between annual assessments with a human validating anything that matters. Reports map to NESA, CBUAE, DFSA, ADHICS, ISO 27001, and PCI DSS expectations, because that is the evidence regulators actually ask for.

If you are mid-renewal and trying to work out whether the scanner spend is the right line item at all, that is a conversation worth having before you sign another multi-year term.
