Grindset Software is a mid-sized international IT company that develops software solutions for financial services. Its core focus is on payment systems and transaction processing for businesses. Every day, thousands of users interact with the company’s web platform to make payments.
Operating in the high-risk FinTech sector, Grindset must comply with international PCI DSS standards, making cybersecurity absolutely critical.
Datami conducted a comprehensive security testing for Grindset Software, focusing on critical components of the payment infrastructure — from web services to databases. Special attention was given to data transmission channels, authentication mechanisms, and encryption methods.
A black-box approach was chosen for the penetration test — testing without access to internal technical documentation, closely simulating the behavior of a potential attacker. During the testing process, we used Metasploit, Burp Suite, and Wireshark, combining both automated and manual testing techniques.
As part of the project, the Datami team focused on a full audit of Grindset Software’s payment system, including the payment processor, web services, databases, and communication channels.
During the testing process, it was decided to strengthen access control measures and update software components.

At the start of the project, Grindset Software’s payment infrastructure faced significant risks: unsecured data transmission channels and weak authentication mechanisms posed a serious threat of financial data leakage.
During the penetration test, Datami identified 15 vulnerabilities: 5 critical (including potential access to the payment processor) and 10 medium-risk issues.
Due to the complexity of the system, specialized security measures and new access control and data protection methods were required.
Grindset Software received clear recommendations:
After implementing the recommendations, the overall risk level was reduced to medium, and the likelihood of financial data leakage decreased by 85%, helping to prevent over $500,000 in potential losses.
The project was completed in 3 weeks, and all critical vulnerabilities were remediated within 48 hours.
In just 3 weeks, Grindset Software, in collaboration with Datami, significantly strengthened the cybersecurity of its payment infrastructure: all key vulnerabilities were identified, PCI DSS compliance was improved, and customer financial data was secured.
All project goals were achieved on time. This case study demonstrates that even FinTech companies require regular penetration testing to prevent data breaches, financial losses, and reputational damage.
The aviation industry is one of the most technologically advanced sectors, significantly influenced by digitalization. At the same time, this increases its vulnerability to cyber threats, which can have catastrophic consequences.
Gaming is a billion-dollar market with big money in circulation, which makes gamers a prime target for cybercriminals. Even in a game, users can lose personal data, money, or access to their accounts.
Phishing has evolved from simple deception into a complex social engineering scheme. Scammers launch mass attacks on personal data, exploiting human inattention and using template phrases to steal trust.
