The closest match here is Invicti, but the right Acunetix replacement depends on what you need to scan. Burp Suite suits manual web testing; Snyk and Semgrep focus more on code security. These are not interchangeable tools. Acunetix pricing is opaque in our comparison, and one Acunetix 360 user reported scans disrupting an application. We compare six options by scope, published price information and the tradeoffs you should check before switching.
01Why people leave Acunetix
Pricing is hard to compare
Our comparison describes Acunetix pricing as opaque, making it harder to weigh costs against alternatives before requesting a quote.
A reported scan disruption
One Acunetix 360 user said a scan generated over 60,000 HTTP 500 responses and led to an application crash and app-pool recycling.
Scanning alone may not be enough
A Reddit commenter argued that vulnerability findings need business context and integrations to be useful; another described scanner implementation as a challenge.
02The alternatives, ranked by fit
- Closest all-in-one fit
InvictiInvictiSwitch to Invicti if you want to keep scanning live applications while broadening coverage to code. Its published profile describes all-in-one AppSec coverage, code and live-app scanning, and deployment flexibility. That makes it the closest fit in this list for teams consolidating security tools. The tradeoffs are opaque pricing and reported API shortcomings, so validate API coverage and get a quote.
Trade-off: Pricing is opaque, and the published profile flags API shortcomings.
6.8/10from
Custom - Manual web testing
Burp SuiteBurp SuiteChoose Burp Suite when your priority is hands-on web application testing, not an automated scanner replacement. The published profile recommends starting with Community and paying $499 a year for Professional only if its limits get in the way. A Reddit user considering scanners said their team lacked the pentesting skills to make Burp useful, so account for expertise and training.
Trade-off: It centers on manual testing, which may require skills or training.
7.2/10from
$41.58/mofree plan - Code and dependencies
SnykSnykSnyk is a better direction if you want security coverage focused on code and dependencies rather than Acunetix-style web and API scanning. Its published profile also names teams adopting AI development tools as a fit. Pricing is listed from $25 with a free plan, but Enterprise costs are opaque and scan noise may create extra triage work.
Trade-off: It is not presented as a direct web and API scanner replacement.
6.2/10from
$25/mofree plan - Code-focused SAST
SemgrepSemgrepPick Semgrep if code scanning and custom rules matter more than keeping DAST in the same platform. Its published profile describes a free AppSec tier, pricing from $15, and a fit for teams prioritizing code-focused SAST. It is a scope change, not a like-for-like Acunetix swap: the profile specifically says to look elsewhere if you need DAST in one platform.
Trade-off: The published profile says it does not provide DAST in one platform.
7.6/10from
$15/mofree plan - Broader SDLC security
VeracodeVeracodeConsider Veracode if your reason for leaving is a need for broader SDLC security coverage, governance or compliance features. The published profile also names organizations securing AI-generated code as a fit. Its price is not listed in our comparison, so request a quote and check the specific coverage you need before treating it as an Acunetix replacement.
Trade-off: Price is not listed, and the published profile flags user reports to check.
4.8/10from
Custom - Secret scanning
TruffleHogTruffleHogTruffleHog makes sense if leaked credentials and secret remediation are the gap Acunetix does not address for your team. Its published profile highlights open-source secret scanning, secret verification and remediation tracking, with a free plan. It is a narrower security tool, not a replacement for web application and API scanning; paid pricing and limits are not published in our comparison.
Trade-off: It focuses on secrets, not web app or API scanning.

Questions people ask
Who makes Acunetix?
The published material does not identify Acunetix’s maker, so we can’t verify the company name from these sources. Check Acunetix’s current official company information before using ownership as a purchasing factor.
Is OpenVAS still free, and how does it compare with Nessus?
The published material does not state whether OpenVAS is still free or compare its features with Nessus. One Reddit user described Nessus as useful for basic vulnerabilities and network security, while seeking a deeper web application scan. That is not enough to rank the two tools.
Which tool is best for vulnerability scanning?
There is no single best pick in this list. Invicti is the closest all-in-one AppSec fit described here; Burp Suite is aimed at manual web testing, while Snyk and Semgrep focus on code security. Match the tool to the assets and workflow you need to cover.
