What makes us different

H-X Technologies started as an independent team of cybersecurity professionals. We gradually grew to the level of an international Managed Security Service Provider (MSSP). We are highly qualified, flexible and reliable:

- Experience in information security. Since 2001, we have gained rich information security assessment and management experience in the state sector, as well as in industrial, pharmaceutical, telecommunication, retail, banking, IT outsourcing, and other spheres in different countries. Read about our security case studies.
- International security certifications. The specialists of H-X earned and maintain internationally recognized security certifications (CISSP, OSCP, CISA, ISO 27001, CEH, LPTP, etc.). These certifications cannot be obtained without verified years of experience and passing rigorous exams. The certifications prove high professionalism and do not allow for illegal or unethical behavior, otherwise, they are immediately revoked.
- Absolute legitimacy and confidentiality. We value our reputation, so we strictly adhere to laws, regulations, our corporate Code of Ethics and Penetration Testing Code of Ethics. We are ethical, white-hat hackers. Our legal support takes into account your rights and interests as well as ours, but also the legitimate rights and interests of third parties. Our specialists sign your commitment forms personally, just like your employees. You would not get such reliability at bug bounty platforms.
- Highest customization and flexibility. We provide professional cybersecurity services for any budget. We even provide free security assessment services. Our Express Pentest service is deeper than just vulnerability scanning but cheaper than pentests. We study every customer's needs carefully to prepare for the project. Unlike other companies, our pre-engagement documentation includes a comprehensive set of detailed project parameters. Our approach allows the customer to understand more accurately what they pay for. Throughout many projects, we have developed and are continually improving our methodology. This is our know-how and what distinguishes us from our competitors.
- Highest quality. H-X uses modern comprehensive penetration testing and security management methodologies and tools. Besides automatic vulnerability scanning, we do manual work. We do not claim that automatic vulnerability scanning is a pentest like others do. H-X not only finds vulnerabilities and shows how they can be exploited by hackers, but helps customers eliminate the vulnerabilities and reduce risks. We develop suggestions for continuous improvement and are tracking changes in the security of our customers 24/7.
