Our Penetration Testing Services

Why Should You Conduct Penetration Testing?

As BARLAS Cyber Security, based in Kağıthane, Istanbul, we provide professional penetration testing services for organizations in Istanbul and across Türkiye. With proper legal authorization and client consent, we use ethical hacking methodologies to test your web applications, servers, and internal and external networks, helping you identify security vulnerabilities before they are exploited.

Our Penetration Testing Methodology

Our penetration tests follow a systematic approach based on the TS 13638 (Information Technology – Security Techniques – Penetration Testing) methodology and aligned with OSSTMM, PTES and OWASP. Tests are carried out under the supervision of our TSE Registered Penetration Test Expert, and the entire process and client data are managed in line with ISO/IEC 27001 information security and ISO 9001 quality management principles:

  1. Information Gathering and Reconnaissance: We determine the attack surface by collecting detailed information about target systems.
  2. Vulnerability Scanning: We identify potential security vulnerabilities using both automatic and manual methods.
  3. Penetration Testing: We attempt to penetrate systems in a controlled manner using the detected vulnerabilities.
  4. Analysis and Reporting: We analyze the discovered vulnerabilities in detail, prioritize findings by risk level, and deliver a detailed report — in line with TS 13638 and ISO/IEC 27001 requirements — with technical and managerial recommendations.
  5. Retesting: After closing security vulnerabilities, we retest to verify the effectiveness of the measures taken.

Frequently Asked Questions about Penetration Testing

How often should we conduct penetration testing?

We recommend conducting penetration tests at least twice a year, more frequently for critical systems, and after major system changes or when deploying new applications. Especially for regulated sectors in Türkiye such as finance, healthcare, and telecom, more frequent testing may be required.

What is the difference between vulnerability assessment and penetration testing?

Vulnerability assessments identify and catalog potential vulnerabilities, while penetration tests actively and safely exploit them to determine their real-world impact. Penetration testing provides a more thorough evaluation of your security posture, especially for complex enterprise environments in Istanbul, Türkiye, and beyond.
