# Xage Security Fabric - Blockchain-based Zero Trust System for Industrial IoT Networks

> Xage Security Fabric is a blockchain-based platform for decentralized identity and access management in industrial IoT networks. The system solves critical security problems such as unpatched devices and unsecured authentication through tamperproof protection and digital certificates. The platform achieved a 10x reduction in computing footprint and can manage up to 10 million assets at 400 Gbps throughput.

## Description

Xage Security was founded in 2017 in Santa Clara (Silicon Valley) and developed Xage Fabric — a decentralised, blockchain-based security platform for industrial systems (ICS/SCADA/OT). The core concept: security data (access rights, authentications, policies) are not stored on a central server but distributed on a blockchain — eliminating any single point of failure.

OT security (Operational Technology) is a critical issue: SCADA systems, industrial controls and sensors in power plants, refineries and factories were designed for reliability, not security. They are often 20-30 years old and cannot be patched like normal IT systems. Attacks such as Stuxnet, Colonial Pipeline hack and Ukraine power grid attacks have shown how vulnerable critical infrastructure is. Xage solves this with a decentralised approach: Xage Fabric distributes trust information (access rights, certificates, policies) on a blockchain across all nodes in the network. Even if individual nodes are compromised, attackers cannot manipulate the blockchain — majority consensus protects integrity. Zero-trust architecture: every access is re-authenticated on every request. Customers include Siemens Energy, US Air Force, Saudi Aramco and other energy suppliers. 2018: $12 million Series A. ARC Advisory Group recognises Xage as a pioneer in the zero-trust OT segment.

## Benefits

- Organisations can securely manage up to 10 million industrial assets while achieving 400 Gbps throughput for critical business processes.
- The platform reduces the computing footprint by a factor of 10 while enabling a tenfold increase in the number of nodes per hierarchy level.
- Companies achieve zero-trust enforcement that is 100 times faster compared to conventional security systems.
- The system supports offline operations and ensures continuous security even during network outages.
- IT teams benefit from automated device authentication and reduced manual effort during security incidents.

## Challenges

- Companies must make significant investments in hardware upgrades and staff training for the new blockchain-based security architecture.
- Implementation requires highly specialised blockchain development resources and deep integration into existing industrial network architectures.
- Edge device resource constraints require customised light client implementations for optimal performance.
- Security specialists need to develop new skills in blockchain technology and decentralised identity management systems.

## Technology foundation

Xage uses a proprietary hierarchical blockchain architecture with local blockchains per site and global synchronization. This solution enables offline operations and uses conditional/supermajority consensus mechanisms for optimal performance in industrial environments.
