THE ECOSYSTEM GAP
Your cyber risk does not stop at your perimeter.
Organisations can invest heavily in internal security while having limited visibility into the suppliers, cloud providers and external dependencies that support critical operations.
MANY ORGANISATIONS CAN ANSWER
• Which security tools do our suppliers use?
• What compliance certifications do they hold?
FEW CAN CONFIDENTLY ANSWER
• Which suppliers create the greatest cyber risk?
• Where are our critical dependencies?
• What happens if a key supplier fails?
• How much cyber risk is inherited from third parties?
A clearer view of third-party and ecosystem risk.
Avereth Nexus examines the external relationships and dependencies that can materially affect organisational cyber risk. It connects supplier criticality, dependency, concentration and assurance evidence into an executive view of ecosystem exposure.
DEPENDENCY ASSURANCE
See how critical operations depend on external providers.
Nexus maps critical business dependencies across the ecosystem to identify concentration risk, single points of failure, hidden dependencies and areas where ownership or assurance evidence is unclear.

Known Fourth-Party Dependency
The objective is not to catalogue every supplier. It is to identify the external dependencies whose failure, compromise or disruption could materially affect the organisation.

THE OUTCOME
Visibility into risk beyond your organisational boundaries.
Leadership gains a clearer view of the cyber risks introduced through suppliers, partners, cloud providers and other external dependencies — including where concentration, critical dependencies or gaps in assurance require attention.
Avereth Nexus provides independent assurance over the third-party and ecosystem risks that can materially affect your organisation.
/ 05 How an assessment works
Three to six weeks, from scope to board.
01
Scope
What is assessed, who we speak to, and the evidence cut-off.
02
Evidence
A tailored request list, a secure portal, and leadership interviews.
03
Assessment
Evidence graded by reliability, verified independently where it matters.
04
Your response
You respond to every preliminary finding before anything is final.
05
Opinion
Final reports and a board session, then quarterly assurance if you choose.
Know where you stand before your insurer, regulator or acquirer asks.
