The Security Bottleneck
Why Traditional API Security Testing Fails
Legacy application scanners were designed for standard web page forms, not structured API endpoints. Testing your APIs with outdated scanners leads to developer friction and critical gaps.
DastPilot was built from the ground up to read API schema definitions directly, executing real attack traffic that adapts to query strings, authentication payloads, and parameter definitions.
Too Manual and Complex
Writing postman security scripts or setting up intercepting proxies takes weeks of security engineering hours.
Noisy False Alerts
Most scanners report alerts based on regex rules alone, without validating payloads or providing actual proof.
SaaS Enterprise Gating
Common DAST vendors gate basic API ingestion behind expensive five-figure enterprise contracts, blocking startups.
How It Works
Three steps from spec to security report
No agents to install. No manual test writing. Point DastPilot at your OpenAPI spec and get a full vulnerability report in minutes.
01
Upload Your Spec
Point DastPilot to your OpenAPI 3.x or Swagger 2.0 spec file or URL, or import a Postman collection (beta). We parse every endpoint, parameter, and schema automatically.
02
DastPilot Attacks
Our engine generates and fires real HTTP requests — fuzzing parameters, testing auth, probing for BOLA and injection across every endpoint.
03
Get a Report
Receive a detailed vulnerability report with exact payloads, CVSS scores, affected endpoints, and step-by-step remediation guidance.
Platform Capabilities
Complete OWASP API Top 10 Coverage
DastPilot tests for every vulnerability category in the OWASP API Security Top 10 — automatically, on every scan, with real attack payloads.
BOLA / IDOR Detection
Automatically tests broken object-level authorization by attempting cross-user resource access across all resource endpoints.
Injection Attacks
SQL, NoSQL, SSTI, command injection — DastPilot fuzzes every parameter with targeted payloads based on field types in your spec.
Broken Authentication
Tests JWT token tampering, expired token acceptance, missing auth headers, and privilege escalation paths.
Security Misconfiguration
Detects overly verbose error messages, missing security headers, and unsafe HTTP methods exposed unintentionally.
Sensitive Data Exposure
Identifies PII, secrets, API tokens, and sensitive fields returned in HTTP responses beyond what the specification declares.
Mass Assignment
Identifies when APIs accept unauthorized property modifications, preventing privilege escalation via parameter tampering.
Product Interface
See DastPilot in Action
A clean, evidence-first interface built for security engineers and developers alike. Every finding includes the exact payload, endpoint, and remediation steps.

Open Vulnerabilities (4)
| Risk Category | API Endpoint | Method | Severity |
|---|---|---|---|
| Broken Object Level Authorization (BOLA) | /v1/users/{userId}/profile | GET | CRITICAL |
| Mass Assignment | /v1/accounts/billing | PUT | HIGH |
| NoSQL Injection | /v1/products/search | GET | HIGH |
| SQL Injection | /v1/feedbacks | POST | HIGH |
Every open finding shows the OWASP category, affected endpoint, HTTP method, and severity — so your team knows exactly what to fix and where.

Intelligent Scan Planning
AI-Based API Scan Planning
Context-aware API fuzzing that analyzes your API's structure and relationships to prioritize risk and find complex vulnerability chains.
- Reads OpenAPI schemas, input formats, and nested object relationships
- Prioritizes Auth rules, write paths, billing flows, and other high-value routes
- Finds Multi-step attack chains that basic one-endpoint fuzzing usually misses
Plans before it probes
Targeted Test Planning
Instead of executing the same basic fuzzing parameters against every endpoint, DastPilot's AI Scan Planner parses schema structures and data models, then builds attacks around how an endpoint actually behaves.
-
Context-Aware Payload Mapping Generates HTTP inputs that follow spec-defined formats so parser errors do not block deeper, stateful tests.
-
Risk-Ranked Path Prioritization Focuses first on authentication flows, write operations, and billing endpoints to spend scan time where exposure is highest.
-
Multi-Step Attack Chaining Links related API calls together to uncover object-level authorization flaws and other sequence-dependent issues.

One API definition (operation) from your OpenAPI specification. If your OpenAPI file contains 10 API definitions (e.g., GET /users, POST /orders, etc.), that counts as 10 APIs for billing purposes.
All APIs added within your first 30 days are free to scan with full access. After 30 days, billing begins at $2.00/API/month. No credit card is required to set up your account and start scanning.
DastPilot covers all 10 categories of the OWASP API Security Top 10, including BOLA/IDOR, broken authentication, injection attacks (SQL, NoSQL, SSTI), mass assignment, security misconfiguration, sensitive data exposure, and more.
Yes. There are no contracts, commitments, or lock-ins. You can delete active specs or deactivate billing directly from your DastPilot dashboard settings.
Yes. Import a Postman Collection v2.0 or v2.1 JSON export, or use the beta guided importer for Postman v3 folders. DastPilot suggests sign-in, test-account, and endpoint-access details for you to review. See the Postman security testing guide.
Yes. Create an API token, trigger a scan for an already-configured target from your pipeline, poll for the result, and fail the build on the severities you choose. Read API security testing in CI/CD for a recommended pipeline design.
ZAP and Burp Suite are general web scanners and proxies that need manual configuration to test API authorization. DastPilot is API-first: it models your roles and resource ownership, then checks every operation for BOLA, BFLA, and other OWASP API Top 10 risks on every scan. Compare them in DastPilot vs OWASP ZAP and Burp Suite alternatives.
