Istanbul Penetration Testing (Pentest) Service: Web, Network, Mobile and API
Quick answer: Is your Istanbul organization's website, network, mobile app or API really secure? A penetration test uses a real attacker's methods, with permission and control, to find flaws before a malicious actor does. DSET serves Istanbul firms via its KAOS platform, web, network, mobile, API and cloud testing, remote and on site. We use known methodologies (OWASP, PTES, NIST), prove every finding and offer a free retest after fixes. Contact: +90 536 662 38 09.
Why Istanbul firms are priority targets
As the economic heart, dense in finance, e-commerce, logistics and software, Istanbul is a high value target. High transaction volume, many staff and a wide supply chain enlarge the attack surface. Automated bots scan every IP and domain continuously, so "who would target us" is a dangerous assumption, every unmanaged system eventually accumulates a flaw.
Test types we offer
- Web application testing: OWASP Top 10 risks (SQL injection, XSS, broken access control, insecure design) with OWASP WSTG.
- Network and infrastructure: external and internal, open ports, weak config, unpatched services, privilege escalation and lateral movement.
- Mobile testing: Android and iOS per OWASP MASVS.
- API security: OWASP API Security Top 10, auth and authorization flaws.
- Cloud configuration review.

Black-box, grey-box, white-box
| Approach | Information given | When |
|---|---|---|
| Black-box | None, external attacker simulation | Realistic external threat |
| Grey-box | Limited, e.g. a standard account | Insider threat, balanced scope |
| White-box | Full access including source | Deepest audit |
Grey-box balances depth and realism for most firms, white-box suits critical apps.
Real testing, not a scan
Some firms run a vulnerability scanner and present its output as a pentest. That is misleading, a scan flags known signatures, produces false positives and never finds business logic flaws (like a user seeing another's order). We test manually, exploit findings in a controlled way to prove they are exploitable, and report each with a CVSS score, evidence and step by step remediation, then verify fixes with a free retest.
KVKK and the remote model
Pentest runs largely remotely from an attacker view, so our Ankara team fully serves Istanbul firms. Scope, rules and the test window are set in writing, critical systems protected, all under a KVKK NDA. KVKK requires "appropriate technical measures", and regular pentesting is a strong way to meet that duty, which directly affects your liability in a breach case.
If you already had a breach
First follow our website got hacked and the IR playbook, then pentest to close the root cause.
FAQ
Will it harm systems? No, scope and rules are set first, destructive tests excluded. How often? After a new app or major change and at least yearly, more for high risk sectors. Scan vs pentest? A scan flags known issues, a pentest proves exploitation and finds logic flaws. Office in Istanbul? Our team is in Ankara, we serve remotely and on site. What do I get? Executive summary, technical findings, CVSS scores, evidence, a prioritized roadmap and a free retest.
