Hire the Best Penetration Testers
in Turkey

Automated vulnerability scanners miss critical business logic flaws and flood reports with false positives. I deliver deep manual penetration testing, protocol-level auditing, and custom offensive tooling to identify and neutralize high-risk attack paths before real-world adversaries exploit them. Certified Ethical Hacker (CEH v13), ISO/IEC 27001 Lead Auditor, and Top 0.55% Ranked Practitioner on Hack The Box. I help engineering teams, SaaS platforms, and enterprise infrastructures secure their applications, networks, and cloud environments against sophisticated threat actors. CORE SECURITY SERVICES & DELIVERABLES • Web Application & API Penetration Testing: Deep manual assessments across REST/GraphQL APIs, OAuth/JWT authentication flaws, complex business logic bypasses (IDOR/BOLA), and OWASP Top 10 vulnerabilities. • Active Directory & Cloud Infrastructure: Domain escalation auditing, Kerberoasting/AS-REP roasting, NTLM Relay vectors, ADCS certificate misconfigurations, and hybrid Entra ID (Azure AD) attack path mapping. • Network & Linux Infrastructure Hardening: Kernel stack tuning (sysctl), ingress traffic filtering (nftables/iptables), DDoS mitigation, and exposed surface lockdown. • Executive & Remediation-Focused Reporting: Actionable, risk-prioritized reports formatted to NIST SP 800-115 and PTES standards—complete with CVSS v3.1 scoring, reproducible PoC chains, and regulatory alignment (GDPR, NIS2, ISO 27001). PROPRIETARY TOOLING & CUSTOM AUTOMATION (NOEMVEX SUITE) When off-the-shelf commercial scanners fail in non-standard or heavily fortified architectures, I build bespoke, object-oriented Python security engines to conduct precision assessments: • APEX-PREDATOR: High-speed Active Directory auditing engine automating unauthenticated SMB signing verification, Zerologon analysis, and Kerberos ticket validation. • WEB-ARCHITECT: Specialized client-side parser for JavaScript deobfuscation, hidden endpoint discovery, and automated PII/credential leak detection. • CHRONOS: Reconnaissance and attack surface mapping framework utilizing Shannon Entropy algorithms for cryptographic key discovery and cloud asset hijacking validation. VERIFIED CREDENTIALS & AUDIT STANDARDS • EC-Council: Certified Ethical Hacker (CEH v13) • ISO/IEC 27001: Information Security Management System (ISMS) Lead Auditor • Cisco: Cybersecurity Defense Analyst & Endpoint Security (SOC Triage, Splunk SPL & PEAK Threat Hunting) • Qualys Certified Specialist: VMDR, Policy Compliance, CSAM & QQL • Rank: Top 0.55% Globally (Pro Hacker Tier) on Hack The Box • Methodologies: NIST SP 800-115, OWASP WSTG, PTES, and OSSTMM Available for scoped penetration tests, fixed-price security assessments, and custom offensive tool development.

Two skillsets, one freelancer. On the security side, I test web applications and servers for vulnerabilities. I identify weaknesses before attackers do, covering everything from injection flaws and authentication bypasses to misconfigurations and access control issues. After every engagement I deliver a detailed report with findings, severity levels, and remediation steps. I also handle WordPress malware removal, server hardening, and VPS setup, deployment, and troubleshooting. On the language side, I'm a native Turkish speaker with professional English fluency. I translate and localize websites, apps, and technical content with a focus on natural tone and cultural accuracy. What I bring to the table: Web application penetration testing and security auditing WordPress security, malware cleanup, and hardening Turkish to English translation and localization SaaS and fintech terminology expertise Developer background (Python, Flask, JavaScript) so I understand the code behind what I translate and test

I’m a Penetration Tester specializing in Web Applications, APIs, and SaaS Security. I manually find vulnerabilities that automated scanners often miss including IDOR/BOLA, broken authentication, authorization flaws, business logic vulnerabilities, SSRF, SQLi, XSS, and tenant-isolation issues. CRTO & CPTS certified | 5+ years offensive security | 49 completed projects I test web applications and APIs built with modern SaaS stacks, including **REST, GraphQL, OAuth, JWT, AWS, Supabase, and PostgreSQL**. My testing can include: • Web application penetration testing • API security testing (REST/GraphQL) • SaaS & multi-tenant security • Authentication & authorization testing • Business logic vulnerability testing • Cloud/backend security reviews • Internal network & Active Directory pentesting • Retesting after remediation You won't receive a report full of scanner output. I manually validate vulnerabilities, provide reproducible PoCs, explain the real-world impact, and give developers clear steps to fix them. Reports include CVSS severity, technical evidence, remediation guidance, and executive summaries** where needed. Testing can be aligned with OWASP, PTES, and NIST SP 800-115, with reporting suitable for security programs such as SOC 2 and ISO 27001. If you're launching a product, preparing for an audit, or want to know whether your application can actually withstand an attacker, I can test it from an attacker's perspective.

I help companies identify real, exploitable security vulnerabilities in production web apps and APIs — especially in authenticated systems where flaws lead to data leaks, account takeovers, and revenue loss. I’m an active Synack Red Team researcher, ranked Top 30 globally for critical vulnerabilities and Top 5 on Featured Targets, delivering high-impact findings on live systems with real users. My security research has also been accepted at Black Hat USA (Arsenal 2023) and DEF CON 31. What I do (manual, attacker-minded testing) - Broken access control (IDOR, privilege escalation, cross-account access) - Authentication & authorization flaws - Business-logic vulnerabilities (payments, checkout, refunds, entitlements) - High-impact web & API issues (SQL Injection, SSRF, XSS, race conditions) What you get - Clear, professional reports with step-by-step reproduction - Impact analysis focused on real-world risk - Actionable remediation guidance - Optional retesting to confirm fixes - Direct developer support to explain root causes and prevent regressions No scanner dumps. No noise. Only manually verified vulnerabilities that can be reproduced, exploited, and fixed. If you’re looking for security testing that reflects how attackers actually break applications — not checkbox compliance — let’s talk.
