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 Scan for Wildcard CORS — Find & Fix It | SableOffensive

What Is Wildcard CORS?

CORS controls which websites can read responses from your API in a browser. The dangerous misconfiguration is allowing any origin (a wildcard, or reflecting the request origin) together with credentials — which lets a malicious site make authenticated requests on your users' behalf and read the results. It is a common default in Express, FastAPI, and Flask apps that "just wanted CORS to work".

How Wildcard CORS Shows Up

Wildcard with credentials

Access-Control-Allow-Origin: * combined with Allow-Credentials: true (or reflecting Origin) lets any site read authenticated responses.

Origin reflection

Echoing back whatever Origin the request sends is effectively a wildcard and bypasses the intended allowlist.

Overly broad allowlists

Allowing entire TLDs, *.vercel.app, or all subdomains exposes you to any app hosted there.

Account takeover chains

Permissive CORS plus a session cookie can let an attacker's page read a victim's private data or perform actions as them.

How the Sable Scan Detects It

Origin probing

We send requests with crafted Origin headers to detect wildcard, reflection, and null-origin acceptance.

Credentialed-request testing

We check whether credentials are allowed alongside a permissive origin — the dangerous combination.

Clear remediation

You get the exact safe CORS config: explicit origins, no wildcard-with-credentials.

Frequently Asked Questions

Is Access-Control-Allow-Origin: * always insecure?

Not by itself for public, unauthenticated data. It becomes dangerous when combined with credentials (cookies/auth) or when you reflect the request origin, which lets any site read authenticated responses. Use explicit allowlists for anything sensitive. Sable tests your real CORS behavior.

How do I fix wildcard CORS safely?

Replace the wildcard with an explicit list of trusted origins, never reflect arbitrary Origin headers, and only enable credentials for those specific origins. Sable reports your current config and the exact safe version.

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.
