Penetration Testing
OSCP-certified offensive security for web, API, mobile, and network targets — OWASP-aligned methodology, reproducible findings, and remediation evidence your auditors accept.
Overview
Arekan penetration testing is engineered for production systems under real constraints: change windows, WAF/CDN layers, multi-tenant data, and compliance evidence requirements. We do not deliver generic scanner exports. Each engagement produces attacker-path narratives, proof-of-concept where safe, prioritized remediation, and retest validation.
Problem
Most organizations discover critical vulnerabilities only after release or incident. Scanner-only assessments miss authorization logic, chained exploits, and production-specific misconfigurations.
Solution
Arekan runs manual + tool-assisted pentests led by OSCP-certified engineers. Findings are mapped to OWASP, MITRE, and your compliance framework with fix guidance your developers can implement in the current sprint.
Result
Clients typically close critical/high findings within one remediation cycle, pass auditor technical reviews faster, and reduce repeat findings on annual retests by 30–50% after the first engagement.
Service scope
Web Application Pentest
Full OWASP Top 10 coverage including authentication, session management, access control, injection, XSS, CSRF, SSRF, and business logic flaws across multi-step workflows.
API Pentest
REST/GraphQL/gRPC review: broken object-level authorization, mass assignment, JWT misuse, rate-limit bypass, and schema abuse with authenticated role matrices.
Mobile Pentest
Android/iOS static and dynamic analysis: insecure storage, certificate pinning bypass paths, deep link abuse, and API backend correlation.
Internal Network Pentest
Assumed-breach scenarios from corporate workstation or VPN segment — lateral movement, AD misconfigurations, and privilege escalation paths.
External Network Pentest
Internet-facing asset discovery, service fingerprinting, exploit-safe validation, and edge control effectiveness (WAF, CDN, rate limits).
Red Team Assessment
Objective-driven adversary simulation with purple-team detection feedback loops — measures time-to-detect and time-to-respond, not checkbox counts.
Methodology
Penetration testing workflow — reconnaissance to verified remediation

Reconnaissance
OSINT, asset inventory, technology fingerprinting, and scope validation against rules of engagement.
- 02
Enumeration
Attack surface mapping, authenticated crawl, API schema discovery, and trust boundary documentation.
- 03
Exploitation
Controlled exploitation with impact proof — no destructive payloads on production without explicit approval.
- 04
Privilege Escalation
Vertical/horizontal movement validation where in-scope; documents blast radius for each finding.
- 05
Reporting
Executive summary, technical finding sheets (CVSS + CWE), reproduction steps, and fix verification checklist.

Web Application Pentest: OWASP Top 10 Remediation SprintFrequently Asked Questions
Typical web/API engagements run 5–15 business days depending on scope size, authentication complexity, and environment count. Large enterprise or red-team programs may extend to 3–4 weeks.
Yes. You receive an executive summary for leadership and a technical report with reproduction steps, evidence, CVSS scoring, and prioritized remediation guidance.
Yes. Web and API tests include OWASP Top 10 coverage plus business-logic and authorization testing beyond automated scanners.
Yes, with controlled rules of engagement, rate limits, and rollback contacts. We prefer staging mirrors when available but routinely test production under change windows.
At minimum annually for regulated environments; quarterly or per major release for high-change SaaS and fintech platforms.
OSCP-certified offensive security engineers from Arekan — led by Ediz Hamurcu, Staff-Level Engineer & Security Architect.
Yes. Remediation retest is included or available as a follow-on sprint to close audit loops with verified evidence.
Scope document, staging/production URLs, test accounts per role, WAF/CDN details, and a technical point of contact for triage during testing.
