Blockchain security solutions

With the world slowly realizing that cryptocurrencies, tokenized assets and smart contracts are the new wild west of financial instruments, threats come as well. Regulatory pressure and cybersecurity risks are harder to mitigate when your technological stack is novel and based on new cryptography-based technologies. Our solutions enable compliance with regulations such as GDPR, CCPA and completion of Privacy Impact Assessment (PIA), Data Protection Impact Assessment (DPIA).

Cryptocurrencies require combining novel cryptography with traditional data, application and product security expertise to solve blockchain security issues.
