Software Development
Applied Cryptography
Information Networks
Our products and services build upon the foundations in these three areas and we always do our best for ensuring the resulting product contains the best of them.
We have been working for you for over 20 years on the following:
Applied Cryptography
Although cryptography has its roots in abstract mathematics, its proper usage always comes with huge real-world impact on mitigating the risks of business operation problems and monetary damages.
Penetration Testing
Information security management includes the necessity to regularly test the systems and infrastructure security. Security auditing and penetration testing is used for performing such regular testing.
Systems Architecture
Professional analysis and viable design and implementation of specialized software or secure server and network infrastructure are the key components for success of new and current services no matter the scale.

However it has turned out that these systems offer little to no inspiration for an object storage systems encryption.
