Detection of security vulnerabilities using penetration testing

Cybersecurity is our forte. The list of our clients and partners includes business and non-governmental organisations, and military organisations from all over Europe. We offer comprehensive, hands-on security testing of internal networks, applications, cloud-based solutions, e-commerce applications and mobile devices. 

Our services include comprehensive security audits and analysis of potential threats. We focus on detecting vulnerabilities in security systems, verifying the reliability of procedures and the effectiveness of your system and hardware security. We can also carry out a security analysis of your source code to detect vulnerabilities that hackers can take advantage of. This allows us to accurately determine the actual vulnerability of your system to potential attacks. 

Penetration testing is the most important tool in our kit. The goal of our penetration tests is to break through your security systems using the same methods a determined criminal would use to achieve the same goal. Our penetration testers have an excellent understanding of intrusion techniques and security system design. Their efforts are summed up in a report with recommendations of improvements that will boost your security posture and minimise the risk of data theft or loss.

What We Actually Do

We'll find vulnerabilities in your web apps before criminals do!

We are experts in the field of cybersecurity. Every day, we keep looking for issues in applications, systems and data communication networks using black box, white box and grey box penetration testing methodologies. We offer meticulous source code analyses. We assess the security of your devices, servers and endpoints, checking their resilience against external and internal threats. We identify real threats and advise you on how to implement effective safeguards.  

We find vulnerabilities in your software written using a variety of programming languages, frameworks and runtime environments, including PHP, Python, C#, Java, NodeJS, CakePHP, Symfony, Spring and .NET MVC. We have identified hundreds of vulnerabilities and helped implementing patches and safeguards that have protected our Clients from XSS, SQL injection, code injection, XSRF and many other attacks. 

Let us find vulnerabilities in your IT system before cybercriminals do!

Dawid Czarnecki

CEO, Cybersecurity Expert
  • Experience: 11 Years
  • Email: dawid.czarnecki@zigrin.com


Dawid Czarnecki started his career by developing a wide variety of web applications. As a web developer, he learned the ins and outs of application development and the common mistakes developers make that affect their applications’ security. In the following years, he focused on developing secure applications, all while learning the techniques used by cybercriminals and the methodologies of breaking through various security systems – all of this led him to become a professional pentester. He decided to devote his career to finding software vulnerabilities and ways to fix them.  

The expertise of Dawid Czarnecki is best shown by the fact that he had worked as an senior penetration tester at NATO Cyber Security Centre, where he was tasked with penetration testing of applications, systems and network infrastructure in NATO member states. His exceptional skills are confirmed by a number of renowned industry certifications, including the Offensive Security Certified Professional (OSCP, also known as the ethical hacking certification), GIAC Certified Incident Handler (GCIH, a certification of expertise and skills required for responding to hacking attacks, issued by Global Information Assurance Certification), and GIAC Certified Web Application Defender (GWEB, a certification of competence in securing web applications). 

Dawid Czarnecki is a member of the GIAC Advisory Board. In 2019, he became the SANS NetWars champion – he placed 3rd in the SANS Core NetWars tournament at the Pen Test Hackfest Summit in Berlin. As an expert, he develops assignments and competency tests for cybersecurity professionals, while participating in Capture the Flag hacking tournaments. This unique set of skills allows him to approach cybersecurity from two perspectives – that of security developers and that of a potential hacker. Thanks to his expertise, Zigrin Security can offer its clients a proper assessment of actual threats to their IT systems and effective countermeasures.  


Hey, my name’s Dawid! I have been helping companies protect their data for 11 years now. In 2017, I founded Zigrin Security. Here, I keep doing what I have always been passionate about, and which has later turned into a mission. I share my knowledge and experience with my Clients to make sure that they can be safe from cyberattacks.  

Company’s methodology stems from observations of real-world security systems. I have seen many companies that have carefully developed security policies in place, but still fail to effectively prevent cyberattacks. This is because documentation is not a diagnosis of the actual state of security and does not protect against threats.  

Zigrin Security offers something else – we use penetration testing to detect actual vulnerabilities and threats. I want you to be a step ahead of criminals and implement corrective actions before an attack occurs. I believe that it is possible to achieve a level of security that will deter cybercriminals and force them to invest more time and money to launch a successful attack. 

Zigrin Security offers you a sense of IT security. We help our Clients stay one step ahead of cybercriminals. We focus on professionalism and consistency. We are goal-oriented. I believe that we will become a significant player in the global cybersecurity market in the near future.
