Specialized & Emerging Technology

Blockchain, IoT & OT Security

Custom security research and manual assessments for specialized hardware, decentralized systems, and industrial infrastructure.

Smart contracts, industrial controllers, and embedded systems each demand purpose-built testing. Our specialist teams work these domains full-time — publishing original research and building custom tools for non-standard environments.

Service Offerings

Smart Contracts

Pre-deployment audit for Solidity/Rust logic and blockchain integrations against exploits.

View Methodology

IoT Devices

Firmware, protocol, and SCADA/PLC security testing without operational downtime.

Safety & Engagement Rules

Testing That Doesn't Disrupt Live Operations

Dedicated Research Allocation

Custom tooling development required for unique environments is included in project scoping.

Operational Safety First

For OT and embedded testing, system availability takes precedence. We utilize lab replicas, passive traffic monitoring, and maintenance windows to protect live operations.

Coordinated Vulnerability Disclosure

Third-party vulnerabilities discovered during testing are handled through coordinated vendor disclosure processes.
