Offensive Security

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.

  1. 01

    Reconnaissance

    OSINT, asset inventory, technology fingerprinting, and scope validation against rules of engagement.

  2. 02

    Enumeration

    Attack surface mapping, authenticated crawl, API schema discovery, and trust boundary documentation.

  3. 03

    Exploitation

    Controlled exploitation with impact proof — no destructive payloads on production without explicit approval.

  4. 04

    Privilege Escalation

    Vertical/horizontal movement validation where in-scope; documents blast radius for each finding.

  5. 05

    Reporting

    Executive summary, technical finding sheets (CVSS + CWE), reproduction steps, and fix verification checklist.

Frequently Asked Questions

How long does a penetration test take?

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.

Do you deliver a report after the pentest?

Yes. You receive an executive summary for leadership and a technical report with reproduction steps, evidence, CVSS scoring, and prioritized remediation guidance.

Is OWASP Top 10 included?

Yes. Web and API tests include OWASP Top 10 coverage plus business-logic and authorization testing beyond automated scanners.

Can pentests run on live production systems?

Yes, with controlled rules of engagement, rate limits, and rollback contacts. We prefer staging mirrors when available but routinely test production under change windows.

How often should we pentest?

At minimum annually for regulated environments; quarterly or per major release for high-change SaaS and fintech platforms.

Who performs the testing?

OSCP-certified offensive security engineers from Arekan — led by Ediz Hamurcu, Staff-Level Engineer & Security Architect.

Do you offer retest after fixes?

Yes. Remediation retest is included or available as a follow-on sprint to close audit loops with verified evidence.

What do you need from us to start?

Scope document, staging/production URLs, test accounts per role, WAF/CDN details, and a technical point of contact for triage during testing.
