A Proven European Technology Builder Since 2010
Our team has spent the last 15 years developing systems to secure real-time data for customers worldwide. We cut our teeth by developing our secure communication (www.kvantphone.com) and cloud call center (www.arenimtel.com) platforms for some of the largest telecom companies. After several years of experience in providing secure communication services for data security sensitive customers, in 2022 we have started to prepare our products for post-quantum security, releasing KvantPhone and KvantMail enabling users to get prepared for the challenges of the post-quantum era. In 2025, Constellation Software Group acquired our CCaaS business, ArenimTel. With the remaining team, we entered a new chapter as a startup again — reinventing ourselves and restarting our journey. Alongside the continued development and sales of our secure communication services, we also began offering full-cycle Engineering-as-a-Service for organizations with mission-critical needs.
