Cyber Security Stack is a deep-tech cybersecurity company pioneering Merkle-Based Detection and Response (MBDR), a new paradigm in autonomous cyber defence built upon the Resonance Protocol.

The Resonance Protocol is not a single product or agent. It represents a new approach to digital architecture, embedding verifiable trust and integrity deep into the fabric of digital ecosystems. This is Zero Trust Architecture realised at its most fundamental level, extending from firmware, kernel, and chip, through operating systems and runtime environments, and across IoT, OT, and IT infrastructures.

The Resonance Protocol and MBDR framework provide a lightweight and highly adaptable technology designed to integrate seamlessly across diverse environments. Using Merkle tree verification and federated trust contracts, it enforces cryptographic trust between devices, processes, and services. This creates a continuously self-auditing ecosystem that detects tampering, isolates compromise in real time, and maintains operational integrity autonomously.

Achieving this vision requires a collaborative effort between academia, manufacturers, and industry. Cyber Security Stack is leading that movement, driving the establishment of the Resonance Protocol as the universal trust standard for the next generation of secure digital infrastructure.

Our mission is to redefine how digital trust is built and maintained, giving organisations infrastructures that cannot be held to ransom.
