What is a pentest, and why should you have it performed??

A pentest, or penetration test, is a simulated cyberattack on your system, network, or web application, conducted by trained security experts. The purpose of a pentest is to identify security flaws and vulnerabilities before malicious hackers can exploit them. Using the same techniques and methods as real attackers, but in a controlled and safe manner, the test ensures thorough assessment. Here are some reasons to conduct a pentest:

  • Identification of Vulnerabilities: A pentest helps detect weak points in your security that might otherwise go unnoticed. This includes both known vulnerabilities and new threats.
  • Prevention of Breaches and Data Protection: By identifying and addressing vulnerabilities, you reduce the risk of data breaches, business disruptions, and reputational damage resulting from a cyberattack.
  • Improvement of Security Measures: The results of a pentest provide valuable insights and recommendations for enhancing your current security measures and policies.
  • Compliance with Regulations and Standards: Many industries require regular security testing to comply with laws and regulations such as GDPR, PCI-DSS, NIS2, and other compliance standards. A pentest can help meet these requirements.
  • Building Trust with Customers and Partners: Demonstrating proactive efforts in securing your systems builds trust with customers and partners, which is crucial for maintaining business relationships.
  • Continuous Improvement: As cyber threats constantly evolve, regular pentesting is essential to stay ahead of emerging risks. Pentests offer valuable insights into your current security posture, allowing you to continuously improve and prepare for new threats.

Approximately 86% of Web Applications Harbor Vulnerabilities

According to the latest statistics from the WhiteHat Security Application Security Statistics Report, approximately 86% of web applications contain at least one vulnerability.

Recommended by the National Cyber Security Centre

The Dutch government's National Cyber Security Centre (NCSC) recommends conducting periodic black-box scans as a vital technical audit measure, scanning the full functionality of web applications. This guidance is outlined in the ICT-Security Guidelines for Web Applications.

“A black-box scan closely mirrors a hacker's methodology as the scanner operates without prior knowledge of the web application under test. Tools designed for black-box scans, such as Web Application Scanners (WAS), conduct a comprehensive array of tests on web applications. These tests include various forms of SQL injection and Cross-Site Scripting (XSS), among others.”



Expertise in Web Development

Web Security Scan operates under the umbrella of DongIT, leveraging our extensive knowledge and experience in both security assessments/pentests and the development of secure web applications. This synergy allows us to apply insights from web development to pentesting and vice versa, enhancing the quality of our service.
