Sikur is a cybersecurity company that develops solutions focused on passwordless authentication, end-to-end encrypted communication, and critical asset management for enterprises and public organizations. The company offers three primary solution areas. Its Secure Communication Platform provides encrypted messaging, voice and video calls, and document sharing via the Sikur Messenger application and a hardened smartphone called Sikur One — a factory-configured device built with security policies designed to prevent data leakage, espionage, and introduction of malicious software. Sikur's Passwordless Authentication and Source Encryption offering is delivered as an SDK with a set of APIs that enables developers to integrate passwordless authentication and source-level encryption into mobile and web applications. The solution eliminates password-based credentials to reduce exposure to phishing and malware, and supports encryption of data in legacy systems before it leaves the device. Its Critical Asset Management solution is built on Zero Trust architecture principles and addresses the convergence of IT, OT, and ICS environments. It provides centralized management and real-time authentication of users, devices, and systems. The solution is designed to mitigate risks arising from interconnected IT and OT networks, including vulnerabilities in IoT devices. Sikur's solutions are designed for compliance with GDPR, the U.S. IoT Cybersecurity Improvement Act (2020), and the UK's Code of Practice for Consumer IoT Security. The company targets organizations seeking to reduce data breach risk, regulatory penalties, and operational disruption from ransomware or unauthorized access.
