ShieldiT Black is a mobile communication security solution designed for high-risk environments including government, defense, and high-security enterprises. It provides military-grade encryption for voice calls, chat, and file sharing on both iOS and Android devices. Key capabilities include end-to-end encrypted communications, malware protection, and anti-theft features such as remote lock, device tracking, and remote data wiping. The solution supports VOIP-to-PSTN calls through secure bridges and encryption technologies, and maintains secure communications both online and offline. ShieldiT Black is managed through a centralized platform called ManageiT, which provides a dashboard for administrators (e.g., CISOs) to oversee endpoint security across the organization. It is available in a multi-tenant version, making it suitable for MSSPs and service providers. The product is optimized to operate without degrading device performance and is compatible with BYOD environments. Communication between ShieldiT clients is encrypted end-to-end. The solution is part of a broader product family from Assac Networks, an Aspis Cyber Company based in Tel Aviv, Israel.
