StackHawk Alternative: What to Use When You've Outgrown Rule-Based API Security
What ApyGuard Does Differently
Multi-Session Behavioral Testing for BOLA Detection
ApyGuard's behavior profiling runs tests across multiple authenticated user sessions. For every endpoint that accepts object IDs, user records, transactions, files, orders, it verifies that User A cannot access User B's objects. This is the only reliable way to detect BOLA at scale.
No rule-based scanner can replicate this. It requires understanding the application's authorization model, not matching a known exploit pattern.
AI That Adapts to Your API's Structure
Rather than running a fixed set of tests, ApyGuard's AI analyzes your API's structure from your OpenAPI spec or live traffic, then generates test cases specific to how your API is built. It adapts to your authentication model, your data types, and your endpoint patterns. The result is more relevant findings and far fewer false positives than generic rule-based scanning.
When Marcus, an AppSec engineer at a mid-size SaaS company, switched his team's scanning workflow to ApyGuard, his first report contained nine findings. He'd been used to triaging 40+ alerts from their previous scanner every week, most of which were false positives his team had stopped reading. All nine ApyGuard findings were real. His team fixed all nine in a single sprint.
First Report in Under Five Minutes
Connect your API via OpenAPI spec or use the API Discovery Extension to map endpoints automatically from live traffic. ApyGuard analyzes your API structure, generates test cases, and runs the first scan, no configuration phase required. Most teams have their first security report before they finish their morning coffee.
Compliance-Ready Reporting Out of the Box
ApyGuard generates audit-ready reports for SOC 2, PCI DSS, GDPR, and OWASP compliance. If you're a startup CTO preparing for your first SOC 2 audit, or a security lead who needs to demonstrate API coverage to a compliance auditor, ApyGuard produces the documentation you need without manual report building.

Pricing Comparison
StackHawk's pricing is available on request for most plan tiers, which makes direct comparison difficult. What's clear from the market is that developer and small-team pricing is a consistent pain point for StackHawk users exploring alternatives.
ApyGuard's pricing is transparent and starts at $129/month for teams with up to 25–50 API endpoints and one monthly scan. The Professional plan at $299/month covers up to 200 endpoints with four scans per month and includes CI/CD integration, compliance reports, and scheduled scans. Enterprise pricing is custom.
For the full breakdown, see ApyGuard pricing plans.
The real pricing question isn't about the monthly fee, it's about the cost of a BOLA vulnerability that ships to production because your scanner didn't catch it. A single API breach costs an average of $4.45 million in total cost according to IBM's Cost of a Data Breach Report. Manual pen testing to find what automated tools miss runs $15,000–$40,000 per engagement. Monthly automated scanning is the fraction-of-the-cost option that runs continuously.
Who Should Choose StackHawk
To be direct: StackHawk is a reasonable choice if all of the following are true for your team.
- You're in an early stage of API security maturity and need to demonstrate coverage quickly
- Your primary vulnerability concerns are injection-type issues and known configuration weaknesses
- You have the time and resources for initial scanner configuration
- Your team is comfortable managing false positive triage as part of the workflow
- You're already deeply integrated into a pipeline that StackHawk supports well
StackHawk is also a good choice for teams that are primarily testing web application surfaces rather than pure API security, since its broader web application scanning coverage is a real advantage in mixed environments.
Who Should Choose ApyGuard
ApyGuard is the better fit if any of the following describes your situation.
You need BOLA detection. If you're building an API that handles per-user data, transactions, records, files, anything tied to a user ID, BOLA is your highest-probability critical vulnerability. Rule-based tools miss it. ApyGuard is built to find it.
False positives are killing your team's trust in security tooling. If your team has stopped acting on scanner output because too many findings are noise, the tool isn't protecting you. ApyGuard's 90% false positive reduction means findings that are worth fixing.
You want a report in minutes, not days. If you're evaluating whether API security testing is worth the investment, ApyGuard's 5-minute time-to-first-scan makes the decision easy. You'll see real findings from your actual APIs before your trial expires.
Compliance is on your roadmap. If SOC 2, PCI DSS, or GDPR compliance is coming in the next 6–12 months, ApyGuard's out-of-the-box compliance reporting saves significant manual effort during audit preparation.
You're a startup that can't afford a security team. ApyGuard's $129/month starting price and self-serve setup means a two-person engineering team can run enterprise-grade API security testing without a dedicated AppSec hire. See how other startups approach this in our API security best practices guide.
Frequently Asked Questions
Does ApyGuard integrate with GitHub Actions like StackHawk does?
Yes. ApyGuard integrates with GitHub Actions, GitLab CI, and Jenkins. You can configure it to run on every pull request and fail the build when critical vulnerabilities are found, the same CI/CD workflow that StackHawk users are familiar with.
Can ApyGuard scan APIs without an OpenAPI spec?
Yes. The ApyGuard API Discovery Extension monitors live traffic and automatically builds an endpoint map, so you don't need a complete spec to start scanning. You can also upload an OpenAPI or Swagger file directly. StackHawk generally requires a spec for meaningful coverage.
Will I get false positives with ApyGuard?
Every scanner produces some false positives. The difference is scale and context. ApyGuard's AI-native approach reduces false positives by 90% compared to traditional rule-based scanners by understanding your API's structure and only flagging genuine behavioral anomalies. Findings come with the exact request, response, and reproduction steps, so you can verify each one quickly.
How does ApyGuard detect BOLA when StackHawk doesn't?
BOLA detection requires testing with two separate authenticated user sessions. ApyGuard creates two test accounts, maps your data-access endpoints, and verifies that Account B cannot access Account A's resources by changing object IDs in requests. This behavioral approach catches authorization failures that no signature-based tool can detect.
Is ApyGuard harder to set up than StackHawk?
The opposite. Most teams get their first scan running and their first report in under five minutes. ApyGuard doesn't require a configuration phase before producing results, connect your API, and the scanner starts immediately.
What OWASP categories does StackHawk miss that ApyGuard covers?
StackHawk has partial coverage of several OWASP API Security Top 10 categories. The categories it handles least well are BOLA (API1), Broken Function Level Authorization (API5), Unrestricted Access to Sensitive Business Flows (API6), and detection of authorization bypass patterns more generally. ApyGuard covers all ten categories, including the three new categories added in the 2023 OWASP update: Business Flows, SSRF, and Unsafe API Consumption.
The Bottom Line
StackHawk built a solid developer-focused DAST tool. The CI/CD integration is good, the UX is polished, and for teams scanning for known vulnerability patterns, it works.
The gap is behavioral testing. Rule-based scanners can't catch what they don't have a signature for. And the most critical API vulnerabilities, BOLA, business logic flaws, authorization bypass, have no signatures to match. They require understanding how your API is supposed to behave and testing whether it actually behaves that way under adversarial conditions.
That's what ApyGuard was built to do. AI-native behavioral analysis across authenticated user sessions, with 35% more vulnerability detection, 90% fewer false positives, and a first report in under five minutes.
