Cyber Security Stack is a UK-based cyber innovation company pioneering the Resonance Protocol - a trust contract framework that ensures system integrity using Merkle-tree-based verification. Our mission is to make digital systems verifiably trustworthy.

The Resonance Protocol is a federated trust protocol that enables systems (devices, applications, or networks) to verify their internal integrity and establish trust contracts with other systems. It detects tampering in real time and isolates compromised components automatically.

Traditional security tools detect or prevent attacks after they happen. The Resonance Protocol builds security into the system's DNA - continuously verifying integrity and revoking trust if anomalies are detected.

Yes, part of it is. The foundational layer (Passive Mode) is open source and being positioned for IETF standardisation to promote adoption. The enterprise version (Active Mode) includes orchestration, network isolation, and advanced telemetry for commercial use.

Both approaches aim to increase transparency and trust on the internet. CSS extends this principle beyond certificates into full-system trust verification, enabling endpoints and IoT devices to self-verify and establish real-time trust boundaries.

CSS primarily works with enterprise IT, OT, and IoT sectors - especially those with complex infrastructures that require verifiable integrity such as councils, manufacturers, and service providers.

CSS has completed the first-generation prototype of the Resonance Protocol, is onboarding early design partners, and is preparing its MVP for pre-seed investment.

A trust contract is a digitally signed agreement between two verified systems, based on their validated Merkle roots and defined communication policies. It allows only trusted systems to exchange data.

If a system deviates from its baseline (indicating tampering), the protocol immediately revokes its trust contract and isolates it from the network until revalidation occurs.

Through enterprise licensing, managed trust orchestration services, and integration consultancy for companies adopting the Resonance Protocol in Active Mode.

CSS collaborates with innovation hubs such as Plexal, Innovate UK, and regional academic and industry networks to accelerate adoption and research in trust-based security.

Organisations can apply to become design partners or pilot sites, gaining early access to the technology and influencing its development roadmap.

CSS is currently in its pre-seed phase and open to investment discussions with angels, VCs, and strategic partners aligned with cyber resilience and IoT security innovation.

CSS is headquartered in Manchester, UK, with a network of partners and collaborators across the country.

The Resonance Protocol is designed to work seamlessly across IT, OT (Operational Technology), and IoT environments. It's lightweight and flexible enough to run on everything from enterprise servers to industrial control systems and IoT devices, adapting to diverse infrastructures without compromising performance.

MBDR is engineered for speed without sacrificing security. Our lightweight agents have minimal footprint, and detection happens in real time (typically under 1ms). The system is designed to be 'super fast'-providing enterprise-grade protection without adding complexity or slowing down operations.

Getting started is simple: our solution includes lightweight agents for endpoint protection, a SaaS platform for centralised management and dashboards, and professional services for onboarding, technical review, and ongoing support. Contact us to schedule a demo and see the Resonance Protocol in action.

The integrity-first architecture means every component continuously proves its authenticity through cryptographic verification. If ransomware attempts to tamper with any layer, the trust chain breaks instantly, and the affected component is automatically rejected and isolated before it can spread-making traditional ransomware attacks ineffective.

Cyber Security Stack (CSS) developed the Resonance Protocol through rigorous research with the University of Manchester combining world-leading cryptographic expertise with cutting-edge federated trust architecture, backed by academic rigour and peer-reviewed security protocols.
