Fintech security solutions

Most current privacy regulations require state-of-the-art encryption when it comes to sensitive data protection. The scope of sensitive data has extended from credit cards and account numbers to personally identifiable information, behavioural analytics, and OLTP workload.

We have built secure systems for both traditional banking and modern fintech. Our solutions allow to comply with regulations such as the GDPR, CCPA, CPRA, SOX, NIST and protect the data without risking the system's usability.
