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 state sector, industry, pharmacy, telecom, retail, banking, IT outsourcing, etc. in different countries. Read about our security case studies.
- International security certifications. The specialists of H-X earned and keep up-to-date internationally recognized security certifications (CISSP, OSCP, CISA, ISO 27001, CEH, LPTP, etc.). These certifications cannot be obtained without confirmed years of experience and gruelling exams passed. The certifications prove high professionalism and do not allow illegal or unethical behavior, otherwise they are immediately revoked.
- Absolute legitimacy and confidentiality. We value our reputation, so strictly adhere to laws, regulations, corporate Code of Ethics and Penetration Testing Code of Ethics. We are ethical, white-hat hackers. Our legal support takes into account not only our and your rights and interests, but also the legitimate rights and interests of third parties. Our specialists sign your commitment forms personally, just like your own employees. You would not get such reliability at bug bounty platforms.
- Highest customization and flexibility. We provide professional cyber security service for any budget. We provide even free security assessment services. Our Express Pentest service is deeper than just a 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 comprehensive set of detailed penetration testing parameters. Our approach allows the customer to understand more accurately what they pay for. During many projects, we have developed and continually improve our methodology. This is our know-how and our distinction from competitors.
- Highest quality. H-X uses modern comprehensive penetration testing and security management methodologies and tools. Besides automatic vulnerability scanning, we actually do manual work. We do not claim that automatic vulnerability scanning is a pentest, like others do. H-X not only finds vulnerabilities and not just shows how exactly hackers can exploit them, but also helps customers eliminate the vulnerabilities and reduce risks. In every project, we develop suggestions for continuous improvement and are tracking changes in the security of our customers over the years.
