End to end Encryption for Active Data.

Our Vision

As data security becomes increasingly important for organizations of all sizes and all industries, the need for end-to-end encryption has never been more urgent. At Aroki Systems we are designing and building a new generation of data management systems that enable end-to-end encryption where your data is never exposed. Not in transit, not in memory, not on disk, never.

Our team has pioneered and developed this technology over the last 15 years and we will soon be making some exciting announcements. And if you’d like to get on our mailing list, shoot us an email at

We look forward to hearing from you!


Your data is protected against data breaches and malicious threats. Your key will never leave your premises.


Run on existing infrastructures without any changes.


Our solutions are based on advanced cryptography but retain the efficiency of systems that operate over data in clear.


Operate on end-to-end encrypted data but retain the functionalities you expect from cleartext systems.
