StackHawk vs Invicti (2026): Developer-First DAST vs Enterprise Platform

If you are choosing between a developer-first scanner and an enterprise platform in 2026, the StackHawk vs Invicti decision comes down to one question: who owns your security testing? StackHawk is a CI-native DAST scanner built on the OWASP ZAP engine - config lives in your repo, scans fire on every pull request, and the price is published per application. Pick it when developers own testing and you want to shift left. Invicti is an enterprise DAST platform with proof-based scanning, asset discovery, and audit-ready compliance reporting on quote-based pricing. Pick it when a central security team governs AppSec across a large, sprawling portfolio. Neither is a penetration test. The rest of this post unpacks that call.

For the wider field - Burp, ZAP, Acunetix, StackHawk, Invicti and more with pricing - see our DAST tools comparison. If your question is really about the free ZAP engine StackHawk is built on, read Acunetix vs OWASP ZAP too.

The short answer

• StackHawk - pick this if you want developer-first DAST that runs in CI/CD from a YAML file in your repo, tests APIs (REST, GraphQL, gRPC) natively, and has published, per-app pricing including a free tier. Best when engineers own security testing and shift-left is the mandate.
• Invicti - pick this if you need an enterprise DAST platform with proof-based scanning to slash false positives, asset discovery to find unknown internet-facing apps and APIs, and audit-ready reporting mapped to compliance frameworks. Best when a security team owns AppSec across dozens or hundreds of apps.
• Both are scanners, not pentests - either one finds roughly 40% of what a manual web application penetration test finds. Use a scanner for continuous coverage, a pentest for depth.

StackHawk vs Invicti: head-to-head

What each tool actually is

• StackHawk is a developer-first dynamic application security testing product. Its scan engine is based on OWASP ZAP, wrapped in a workflow built for engineers: a stackhawk.yml config that lives in version control next to your application code, first-class integration with 12-plus CI/CD platforms (GitHub Actions, GitLab CI, Jenkins, CircleCI, Azure Pipelines and more), and a hosted platform for triage. It offers strong API testing - REST via OpenAPI, GraphQL via introspection, SOAP, and gRPC - and can discover undocumented endpoints from source. The whole pitch is shift-left: put the scan where developers already work so vulnerabilities get caught before merge, not months later.
• Invicti (formerly Netsparker, and the parent of Acunetix) is an enterprise DAST platform. Its headline is proof-based scanning: for a large share of findings it safely crafts a non-destructive exploit and returns proof before reporting, which is what drives its marketed 99.98% accuracy on confirmed classes and keeps false positives low. Beyond scanning, Invicti leans into asset discovery - it surfaces every website, app, and API across your organisation, including shadow assets, and applies predictive risk scoring so you know what to test first. Add role-based access, multi-engine scanning, and compliance-mapped reporting, and you have a platform built for a security team governing a big, messy estate.

Who owns the testing: shift-left vs security-team ownership

This is the real fork in the road, and it matters more than any feature checkbox.

StackHawk assumes developers own security testing. The config is a file in the repo. The scan runs in the pipeline the engineers already built. Results land where developers already look. That is a deliberate cultural bet: security gets caught early because it is embedded in the delivery workflow, not bolted on by a separate team weeks later. For a fast-moving product org shipping multiple times a day, that is exactly the model you want - and it is why StackHawk describes itself as developer-first rather than security-first.

Invicti assumes a security team owns AppSec. The console is central. Policies, scan scheduling, asset inventory, and reporting are governed from one place by people whose job is application security. Developers consume the findings; they do not own the tool. For an enterprise with a formal AppSec function, a compliance mandate, and a portfolio too large for any single team to hold in their head, that centralisation is the point.

Neither model is better in the abstract. If your engineers write the pipelines and you want security caught pre-merge, StackHawk fits the org. If a central team is accountable for coverage and audit evidence across hundreds of apps, Invicti fits the org. Pick the tool that matches who is actually responsible.

API and GraphQL testing

Both tools test APIs, which matters because APIs are where a growing share of real attack surface now lives - and where automated scanners diverge.

• StackHawk treats API testing as a first-class use case. It scans REST from an OpenAPI spec, GraphQL via introspection, plus SOAP and gRPC, and can discover undocumented endpoints from source. Because it runs in CI against the app you are shipping, it is well suited to teams that push API changes continuously and want each change tested before it merges.
• Invicti scans APIs too, but its distinctive move is API discovery at the organisation level - finding shadow, undocumented, and forgotten APIs across your attack surface, including from source and network traffic. That is a different problem from testing the API you already know about.

The clean way to think about it: StackHawk tests the APIs your team ships; Invicti finds the APIs your org forgot it exposed. API-first product teams usually want the former. Enterprises worried about unknown attack surface want the latter. Either way, both cover API classes only partially - authorization and business-logic flaws in APIs still need manual API security testing.

False positives and detection accuracy

Because StackHawk runs a ZAP-based engine, its detection profile mirrors ZAP: genuinely competitive on core OWASP Top 10 classes like injection and misconfiguration, but it flags candidate findings that need human triage. StackHawk’s UX and tuning smooth that over compared with raw ZAP, but the underlying model still hands you some noise to filter.

Invicti’s proof-based scanning is its clearest technical edge here. By auto-verifying exploitability before reporting, it removes a large slice of the triage burden - a confirmed finding arrives with proof attached, so a developer can act without re-checking whether it is real. Across a big portfolio, that saved triage time is the whole business case.

The honest framing: on raw detection of common classes, the gap is smaller than the price difference suggests, because StackHawk inherits a capable open-source engine. The gap widens on operational overhead - Invicti’s confirmed-first model costs less human time per finding, which is exactly what a lean security team running hundreds of apps is buying.

Pricing transparency

This is a differentiator worth calling out on its own, because buyers feel it immediately.

• StackHawk publishes its pricing. There is a free tier, then paid tiers priced per application, with cost tied to the engineers contributing code to the apps under test (market figures put paid subscriptions around USD 400 per app per month). You can see the model, estimate your spend, and often start self-serve. For a developer-led team that wants to try before committing, that transparency is a real advantage.
• Invicti is quote-based. It does not publish list prices; you engage sales, scope your asset count, and get a figure. Enterprise DAST platforms in Invicti’s class typically start well into five figures per year and scale with the number of assets, often on a multi-year contract. That is normal for enterprise software, but it means slower, sales-led buying and less upfront cost predictability.

If self-serve, predictable, per-app cost matters, StackHawk’s published model wins outright. If you are already running an enterprise procurement process and need the discovery-plus-accuracy platform, Invicti’s quote is just how enterprise DAST is sold.

Verdict by buyer type

• Startup or product team, developers own security: StackHawk. CI-native, per-app pricing, free tier to start, strong API and GraphQL testing. Spend the saved budget on a periodic manual pentest.
• API-first SaaS shipping continuously: StackHawk for pre-merge scanning of REST/GraphQL/gRPC in the pipeline, so API changes get tested before they merge.
• Enterprise with a central AppSec team and a large portfolio: Invicti for proof-based accuracy, org-wide asset discovery, and audit-ready reporting that scales across hundreds of apps.
• Regulated UAE enterprise (bank, fintech, VARA-licensed): Invicti for compliance-mapped, audit-ready output and discovery of unknown internet-facing assets - plus mandatory manual penetration testing, because CBUAE, DFSA, and VARA expect human-led evidence, not scanner output.
• Team unsure of its own attack surface: Invicti, because asset discovery finds the apps and APIs a per-app scanner like StackHawk never gets pointed at.

What both scanners miss

Here is the part no scanner vendor leads with. StackHawk and Invicti are both automated scanners, and automated scanning finds roughly 40% of what a manual web application penetration test finds. They excel at the pattern-detectable bugs - injection, misconfiguration, missing headers, known-vulnerable components. They are weak or blind on exactly the flaws that cause the worst breaches:

• Broken access control - a scanner cannot know that user A should not see user B’s invoice. A human tester can.
• Business-logic flaws - price manipulation, workflow bypass, abuse of legitimate features. No signature and no proof-based engine catches these.
• Chained exploits - three low-severity findings that combine into full account takeover. Scanners report them as three separate low-severity notes.
• Authorization edge cases - horizontal and vertical privilege escalation that only surfaces when a tester reasons about roles and state.

That is not a knock on either tool. It is the boundary of what automation does. StackHawk in CI or Invicti across the estate is the continuous, cheap baseline. The serious findings, the ones that turn into breach headlines, come from a person driving the test. If you have run StackHawk or Invicti and want to know what they missed, a web application pentest from pentest.ae delivers exploited findings, business-impact proof, and a remediation-ready report - not raw scanner output.
