Check Your Website's Security for Free. Fix Every Vulnerability for a Flat €99.
Hi, I'm Cahit Oz. Modern websites and AI-built apps ship faster than ever—but often leave exposed API keys, missing security headers, and broken access rules. Because I combine senior software engineering with AI security workflows, I audit your site for free and fix what we find for a small, reasonable flat sum instead of €2400+ agency fees.
Instant Passive Security Header & TLS Preview
Non-intrusive check of 8 baseline HTTP security controls in 2 seconds
AI Multiplies How Many Websites I Can Secure — And I Pass Those Savings to You
Security shouldn't be a luxury reserved for enterprises with €10,000 budgets. By pairing automated AI reconnaissance with my hands-on software engineering experience, what used to take days now takes hours.
Traditional Security Agency
€2,400+Built for slow enterprise procurement, not agile founders or SMBs.
- Weeks of sales calls and scoping paperwork
- Dumps a 60-page PDF on you without fixing your code
- High overhead billed directly to you
Generic Automated Scanners
€49–€199/moAlerts you to problems, but leaves you to figure out the fix alone.
- Hundreds of noisy warnings and false positives
- Misses business-logic & database rule flaws
- Zero hands-on engineering or code patches

What I Inspect & Fix on Your Website
Every website check covers the real-world attack vectors that automated bots and opportunists exploit every day.
HTTP Security Headers & CSP
Hardening Content-Security-Policy, HSTS, X-Frame-Options, X-Content-Type-Options, and Permissions-Policy without breaking your analytics or fonts.
Exposed Secrets & Bundle Leaks
Scanning client JS bundles, source maps, .env files, and public git commits for leaked API keys, Stripe secrets, and private service tokens.
Auth, Cookies & DB Security Rules
Auditing Supabase RLS policies, Firebase Firestore rules, session cookies (HttpOnly, Secure, SameSite), and broken object-level authorization.
API Routes & OWASP Top 10
Checking unprotected API endpoints, missing rate limits, permissive CORS wildcards, Cross-Site Scripting (XSS), CSRF, and injection vectors.
SSL/TLS, DNS & Email Spoofing
Verifying TLS 1.3 enforcement, strict HTTPS redirects, subdomain risks, and anti-spoofing DNS records (SPF, DKIM, DMARC, CAA).
Framework & Dependency CVEs
Identifying exploitable vulnerabilities in Next.js, React, Node.js, WordPress plugins, or Python packages—and upgrading them safely.

How can you offer a full security audit & fix for €99 when agencies charge €2400+?
Traditional security consultancies bill for days of manual boilerplate scanning, account managers, and 60-page generic PDFs. As a senior software engineer leveraging specialized AI security agents and automated recon pipelines, I can pinpoint misconfigurations, exposed secrets, broken auth rules, and missing security headers in a fraction of the time—and write the exact code patch for you immediately.
Will the security check slow down or break my live website?
Never. The initial check is 100% passive and non-destructive. We inspect HTTP response headers, TLS certificates, publicly exposed endpoints (.env, source maps, git metadata), CORS policies, and client-side bundles without flooding your server or altering production data.
What if my website was built with AI tools (Cursor, Lovable, Bolt, v0, Antigravity)?
AI-generated apps are my specialty! Rapidly built apps frequently ship with permissive CORS, missing Content-Security-Policy headers, exposed NEXT_PUBLIC secrets, unauthenticated API routes, or overly broad Supabase RLS / Firebase Firestore security rules. I audit and lock these down quickly so you can scale with confidence.
How do you actually apply the fixes to my website?
You choose the workflow you are most comfortable with: (1) I can submit a clean, documented Pull Request to your GitHub/GitLab repository, (2) we can pair on a 20-minute screen-share session where we apply and test the fixes live, or (3) I can send you copy-paste configuration blocks tailored to your exact stack (Next.js, Vercel, Cloudflare, Nginx, WordPress).
When do I pay the flat fee?
You start with the Free Security Check (€0). Once I send you the findings, if you want me to fix the issues for you, we agree on the flat fee and you pay only after the patches are delivered and verified.
What happens if my website already has zero security issues?
Then you pay €0 and get peace of mind! I will confirm that your perimeter headers, TLS configuration, and public attack surface look clean.
