Smart, connected devices are already an integral part of our lives, in business and at home. And, with the rollout of 5G, this is expected to scale multi-fold. IoT and 5G will open up previously closed systems to remote access & control, and existing security solutions are simply unable to keep pace, scale up and address the security challenges facing this new always-on, fast-evolving interconnected world. The IoT Armour solution by BlockArmour is explicitly designed to secure connected devices, integrated IoT systems, and associated 5G communication networks. The solution is powered by Software Defined Perimeter (SDP) architecture & Blockchain technology. SDP architecture renders core systems and IoT gateways invisible to attackers; while customized agents along with private Blockchain technology deliver a new breed of digital identity and access control for all connected devices.
