Cyber Risks

Cyber Exposure

Cyber exposure is the measurable attack surface — and the starting point of any objective cybersecurity assessment.

Cyber exposure refers to the extent to which an organisation or supplier is vulnerable through externally visible vulnerabilities, data leaks and configuration errors.

What does cyber exposure measure?

Cyber exposure quantifies: open ports and exposed services, unpatched vulnerabilities (CVEs) weighted by severity, dark web leaks and credential exposure, insecure SSL/TLS configurations, missing email security (SPF/DKIM/DMARC), exposed admin interfaces and login pages, outdated software versions, and misconfigured cloud resources.

Externally measurable — with no supplier involvement

Cyber exposure is measured exclusively from external data sources — suppliers don't need to provide information or grant access.

Managing cyber exposure across the supplier portfolio

In a TPRM context, cyber exposure measurement enables: daily updates to the risk picture for every supplier, trend analysis (is a supplier's exposure increasing or decreasing?), benchmarking against the industry average, early escalation on critical exposure, and regulatory-compliant documentation.

Unknown exposure is the biggest risk

What isn't measured can't be managed. 80% of all cyberattacks exploit vulnerabilities that are externally known but internally unknown.

FAQ

How does cyber exposure differ from attack surface?+

Attack surface describes all potential points of attack. Cyber exposure additionally assesses how exploitable those points are — i.e. the actual risk potential.

Can I measure my suppliers' cyber exposure without their knowledge?+

Yes — cyber exposure measurement is based on passive, external observation. No active scanning of the supplier's infrastructure is required.
