About Cyber Tzar

Cyber Tzar was established to help businesses improve their understanding and management of cyber risk by using quantitative Cyber Scoring.

Our Key Principles

Responsibility first
Supply chain cyber risk is a board-level issue. We design our platform to support directors, CISOs and security leaders in meeting their accountability with clarity and confidence.

UK-first by design
Cyber Tzar is built, hosted and operated entirely in the UK. Our team, infrastructure and data handling are aligned to UK regulatory, legal and operational expectations — with no offshore outsourcing.

Real-world insight, not theory
We base our intelligence on what is actually happening across UK organisations today. Our platform is informed by one of the largest privately owned vulnerability datasets in the UK, giving genuine visibility into systemic risk.

Action over awareness
Reporting alone does not reduce risk. We focus on prioritised findings and practical remediation that organisations and suppliers can act on quickly.

Built for supply chains
Supply chain security is not traditional cyber security at scale. Our platform is purpose-built to understand complex supplier ecosystems and the risks they introduce.

Clarity at scale
From a single supplier to tens of thousands, we deliver clear, top-down risk reporting that enables better decisions without overwhelming teams.
