Arenim Technologies

What Arenim Technologies does

Arenim Technologies (UK-incorporated Arenim Ltd., operating from Budapest and Vienna) builds secure communication products and delivers engineering services for business-critical environments. The product suite centers on KvantPhone, a post-quantum encrypted voice, messaging, conferencing, and file-sharing service using peer-to-peer architecture with device-side encryption and no central servers; KvantMail, an end-to-end encrypted email solution; and the Secure Call Center (SCC) SDK plus SCC Gateway, which enables financial institutions to offer authenticated in-app voice, messaging, and video communications that mitigate vishing and caller-ID spoofing. All products share a post-quantum cryptographic foundation and have undergone third-party security assessments (including NCC Group). The company makes money through two streams: recurring subscriptions and licenses for the secure communication products (including KvantPhone via iOS and Android app stores), and Engineering-as-a-Service engagements (AI-native development, secure software development, AI-driven digital transformation, DevOps) billed on project or retainer bases. Customers span government and defense, financial services, telecom, retail, healthcare, and consulting — with named logos including BCG, Vodafone, OTP Bank, KPMG, Electrolux, Bauhaus, and Rossmann — and the products are reported in use across more than 100 countries with active customers in 25+ countries. Following the August 2025 sale of its cloud call center business (ArenimTel) to Constellation Software Inc., the founders retained the Arenim brand and cybersecurity engineering team and are reinvesting focus into the KvantPhone/KvantMail/SCC portfolio and Engineering-as-a-Service.

Core offering

Arenim Technologies sells post-quantum secure communication products (KvantPhone for encrypted voice/messaging/conferencing, KvantMail for end-to-end encrypted email, and Secure Call Center for authenticated customer communications) and provides Engineering-as-a-Service covering AI-native software development, secure software development, digital transformation with AI, and DevOps. The products use peer-to-peer architecture with device-side encryption, and the engineering services leverage AI-assisted workflows to shorten delivery timelines for business-critical environments.

Product overview

Arenim Technologies offers a portfolio of secure communication products and Engineering-as-a-Service. The product suite centers on three core secure communication solutions: KvantPhone (quantum-resistant encrypted calls and messaging), KvantMail (end-to-end encrypted email), and Secure Call Center (SCC - scam-prevention SDK for financial institutions). These are complemented by AI-native software development, secure software development, AI-driven digital transformation, and DevOps services. The products share a foundation in post-quantum cryptography and security-by-design principles, with the SCC including a gateway component for call-center integration. Engineering services provide elastic capacity for organizations with mission-critical development needs.
