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 Next.js Apps — Find Real Vulnerabilities | SableOffensive

Why Next.js Apps Get Hacked

Next.js makes it trivially easy to blur the line between server and client. That speed is exactly why Next.js apps leak secrets and ship insecure defaults. Environment variables prefixed with NEXT_PUBLIC_ get inlined into the browser bundle, Server Actions and Route Handlers can expose internal logic, and middleware auth is easy to bypass when matchers are wrong. We scan for the failure modes that hit real Next.js deployments.

Common Next.js Vulnerabilities

Leaked NEXT_PUBLIC_ secrets

Any env var prefixed with NEXT_PUBLIC_ is baked into the client bundle. Teams routinely expose service keys, Supabase service-role keys, and third-party API tokens this way.

Server Action / SSRF exposure

Server Actions and fetch-on-server patterns can be abused for Server-Side Request Forgery — older Next.js versions had a documented SSRF (CVE-2024-34351). Keep Next.js patched and validate every server-side URL.

Middleware auth bypass

Auth enforced only in middleware with a loose matcher (or relying on a spoofable header) lets attackers reach protected routes and API handlers directly.

Missing security headers

Next.js ships no CSP, HSTS, or X-Frame-Options by default. They must be added in next.config headers() or middleware — most apps never do.

Exposed Route Handler logic

API routes under app/api with no authorization check, no rate limiting, and verbose error messages that leak stack traces and internal paths.

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

How do I check if my Next.js app is leaking secrets?

Search your deployed JavaScript bundle for any value that should be server-only. In Next.js, only variables prefixed with NEXT_PUBLIC_ are meant to be public — anything sensitive with that prefix is exposed. Sable scans your live bundle for known secret patterns automatically and flags exactly which key is exposed and where.

What is the most common Next.js security mistake?

Shipping secrets to the client via NEXT_PUBLIC_ variables, and never setting security headers (CSP, HSTS, X-Frame-Options) because Next.js does not add them by default. Both are caught in seconds by a Sable scan.

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.
