Zero Trust Access for Enterprise, Cloud and IoT via Software Defined Perimeter

Block Armour is a cybersecurity venture building zero trust access controls for enterprise systems, cloud workloads and connected devices. Its intended customers are organisations running distributed hybrid and multi-cloud estates, alongside critical infrastructure, smart city and Industry 4.0 operators. The founding team of Narayan Neelakantan, Abhijit Dhongade and Floyd DCosta draws on prior CISO and IT risk leadership at India's National Stock Exchange and consulting work at Capgemini, and the company now operates from the USA, UK, Singapore and India.

The Secure Shield platform pairs a software defined perimeter with private blockchain technology, aligned to the NIST zero trust framework. A controller with an embedded policy engine authenticates and authorises every endpoint before any connection is permitted, so protected application infrastructure remains effectively invisible to unauthorised parties. Secured gateways broker access for cloud and IoT endpoints, device posture checks gate compliance, and communications run over 4096-bit RSA encryption. Blockchain-backed digital identities and time-stamped immutable logs supply the audit trail.

Positioning leans on consolidation: a single cybersecurity mesh intended to replace several point products across on-premises, cloud and multi-cloud footprints, extended by UniAuth for zero trust multi-factor authentication deployed without code changes, and IoT Armour for device, 5G and critical infrastructure protection. GigaOm named the company a Market Outperformer in its 2023 Zero Trust Network Access radar; it was accelerated by Airbus, cited among the top 25 cybersecurity innovations worldwide, and sells through Azure, Oracle Cloud and India's GeM marketplaces.
