What is Agent-as-a-Service pentesting?

Agent-as-a-Service (AaaS) pentesting lets you chat with autonomous pentesting agents that scan your application on demand. Instead of waiting weeks for a manual engagement, you talk to specialized agents — pen-scout (recon and surface mapping), pen-recon (deeper enumeration), pen-triage (validates and prioritizes findings), pen-fixer (remediation guidance), and pen-compliance (OWASP/standards mapping). Findings are validated with proof-of-concept and re-test, not just flagged. You start with 150 free credits, no credit card.

What are credits and how do they work?

Credits are how you run agent scans. Each scan or agent action consumes credits based on its depth. New accounts get 150 free credits with no card required. After that you can buy one-time credit packs ($29, $79, or $199) for pay-as-you-go use, or subscribe to a monthly tier ($49, $149, or $399/mo) for continuous, on-demand pentesting. The agents pen-scout, pen-recon, pen-triage, pen-fixer and pen-compliance all draw from the same credit balance.

Yes. Every new account gets 150 free credits with no credit card required — enough to chat with the pentesting agents and run real scans against your app. There is also a free security headers scan at sable.somoswilab.com/free-scan and a sample report at sable.somoswilab.com/sample-report. The free tier runs on OpenRouter models so you can evaluate the autonomous agents before paying.

What is penetration testing for startups?

Penetration testing (pentesting) is a simulated cyberattack against your application to find security vulnerabilities before real attackers do. For startups, we focus on the issues that matter most at your stage: authentication flaws, data exposure, API security, and common mistakes in modern stacks like Next.js, Supabase, and Firebase.

How much does a pentest cost?

Traditional pentests cost $10,000-$50,000+. SableOffensive starts at $29 for a Pre-Launch Check covering OWASP Top 10 and secrets detection. Founder Shield ($79) adds IDOR testing, auth bypass, and a debrief call. Scale Secure ($199) is a full-scope assessment. Every plan includes a professional report with remediation steps.

How long does a security scan take?

Pre-Launch Check reports are delivered within 24-48 hours. Founder Shield and Scale Secure may take 2-3 business days depending on the complexity of your application.

What do I need to provide?

At minimum, just your application URL. For more comprehensive testing, we may ask for staging credentials, API documentation, or GitHub repository access. We sign NDAs for all engagements.

What is OWASP Top 10?

OWASP Top 10 is the industry standard list of the most critical web application security risks. It includes injection attacks, broken authentication, cross-site scripting (XSS), server-side request forgery (SSRF), and security misconfigurations. Every SableOffensive assessment tests against the full OWASP Top 10.

Do you test AI-generated code?

Yes. Code generated by AI tools like Cursor, GitHub Copilot, and v0 often contains subtle security issues: hardcoded secrets, missing input validation, insecure API patterns, and overly permissive access controls. We have specific testing procedures for AI-generated codebases.

How do you secure Supabase and Firebase apps?

For Supabase, we audit Row Level Security (RLS) policies, test for direct table access, and check for exposed service keys. For Firebase, we review security rules, test Firestore/RTDB access patterns, and check Cloud Functions for vulnerabilities.

What if you find zero vulnerabilities?

50% money back guarantee. If our scan finds zero security issues, you get half your money back.

Is there a free pentesting option?

Yes. SableOffensive offers a free security headers scan at sable.somoswilab.com/free-scan. It instantly checks your website for 8 critical security headers (HSTS, CSP, X-Frame-Options, and more) and gives you an A-F grade with copy-paste fixes. No signup or payment required.

Can I get a free vulnerability scan?

Our free security headers check scans your website instantly and grades your security posture. For a deeper free assessment, contact us — we occasionally offer complimentary scans for early-stage startups and open source projects.

Free Security Scan for FastAPI Apps — Find Real Vulnerabilities | SableOffensive

Why FastAPI Apps Get Hacked

FastAPI auto-generates an OpenAPI spec and interactive docs (/docs and /openapi.json), which is great for development and a gift to attackers in production. It maps your entire API surface. Combined with dependency-based auth that is easy to forget on a route and the usual IDOR risks, an exposed FastAPI service is a clear target. We scan exactly that surface.

Common FastAPI Vulnerabilities

Exposed OpenAPI docs

/docs, /redoc, and /openapi.json publish your complete endpoint list, parameters, and schemas — a full map for an attacker. Disable or protect them in production.

Missing auth on routes

FastAPI auth is a per-route dependency. Forget the Depends(...) on one endpoint and it is wide open while the rest look protected.

Broken object-level authorization (IDOR)

Path params like /items/{id} that fetch by ID without an ownership check let any authenticated user read others' data.

Permissive CORS

CORSMiddleware with allow_origins=["*"] plus allow_credentials enables cross-origin abuse of authenticated sessions.

Missing rate limiting & headers

No built-in rate limiting and no security headers; both must be added at the app or proxy layer.

What the Sable Scan Checks

Exposed secrets & API keys

We scan your client-side bundles and responses for leaked API keys, tokens, database URLs, and 100+ secret patterns that ship to the browser by accident.

Security headers & TLS

HSTS, CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy, and TLS protocol/cipher configuration — graded A-F with copy-paste fixes.

CORS & access control

Overly permissive CORS, wildcard origins with credentials, and broken object-level authorization (IDOR/BOLA) where one user can reach another user's data.

Injection & API surface

SQL/NoSQL injection, exposed OpenAPI/Swagger specs, GraphQL introspection, mass assignment, missing rate limits, and excessive data exposure.

OWASP Top 10 coverage

Autonomous pentesting agents test against the full OWASP Top 10 2025, validate each finding with a proof-of-concept, and re-test after you fix.

Validated findings, not noise

Every reported issue is confirmed by an agent before it reaches you — so you get real, exploitable findings with severity and remediation, not scanner spam.

Frequently Asked Questions

Should I disable FastAPI docs in production?

Yes, or protect them behind auth. /docs, /redoc, and /openapi.json publish your entire API surface — endpoints, parameters, and schemas — which accelerates attacks. Set docs_url=None / openapi_url=None or gate them. Sable detects exposed OpenAPI specs.

How does authorization break in FastAPI?

Auth in FastAPI is a per-route Depends() dependency, so a single missing dependency leaves an endpoint unprotected, and ID-based routes without ownership checks cause IDOR. Sable enumerates your routes and tests each for missing auth and cross-user access.

Is the security scan really free?

Yes. The Headers Scan runs instantly with no signup. For the full agent scan you create a free account and get 150 founder credits with no credit card required — enough to run real scans against your app on demand. Paid credit packs and monthly tiers exist for continuous testing, but you can start for free.

How does Sable scan my app?

Sable runs autonomous pentesting agents (pen-scout, pen-recon, pen-triage, pen-fixer, pen-compliance) that map your attack surface, test against the OWASP Top 10, validate every finding with a proof-of-concept, and re-test after you ship a fix. You chat with the agents on demand instead of waiting weeks for a manual engagement.

Will the scan break or slow down my production app?

No. Scans are designed to be safe and non-destructive. We demonstrate impact with proof-of-concept evidence rather than causing damage, and we never exfiltrate or alter your data.
