E2ERisk helps defence primes and MOD-adjacent suppliers cascade assurance down the tiers, collect evidence back up, and prove cyber posture against MOD expectations in one controlled evidence model.
Primes and MOD-adjacent suppliers carry obligations that cascade through tier 1, tier 2 and beyond: every subcontractor inherits requirements, and the prime has to show current posture across a chain it does not directly control - without exposing sensitive detail in the process.
E2ERisk models that flow-down. Assurance requirements pass down the chain, evidence is collected back up it, and supplier posture - assessment results, outside-in exposure and remediation status - is visible end to end, mapped to DCPP risk profiles and the standards defence supply chains are held to.

MOD expectations do not stop at the prime. Through the Defence Cyber Protection Partnership and Def Stan 05-138, a contract's cyber requirements cascade through tier 1, tier 2 and the smaller suppliers beyond, and the prime is accountable for posture across a chain it does not directly control.
The hard part is the evidence. Each subcontractor inherits requirements, but proving the current position across the whole chain - without burying SMEs in duplicate questionnaires or exposing sensitive detail - is exactly where spreadsheets and email break down.
Every supplier follows a consistent path, from the moment it is engaged through to continuous monitoring long after a contract is awarded. How deep the assessment goes is set by the tier and the sensitivity of the work, so effort concentrates on the suppliers that carry real risk rather than every name on the bid.
Assurance does not stop at tier one - it follows the contract down.
The obligations do not change; what changes is whether flow-down is real or assumed. Run on spreadsheets and email, requirements are passed down and then trusted, subcontractor posture is out of sight, and Def Stan evidence is rebuilt from scratch for every bid.
| What you do | Spreadsheets + email | E2ERisk |
|---|---|---|
| Flow-down | Trust and hope | Cascaded and evidenced |
| Subcontractors | Out of sight | Posture surfaced |
| DCPP profiles | Per-supplier paperwork | Tracked across the estate |
| Def Stan evidence | Rebuilt each bid | Captured once, re-used |
| Posture | A point in time | Monitored continuously |
| MOD assurance request | A scramble | A current pack on demand |
The result is flow-down you can actually evidence: posture visible across every tier, DCPP profiles tracked in one place, and a current assurance pack ready the moment a prime, an auditor or the MOD asks.
Most defence teams start with Supplier Assurance and the Threat Centre: the tiers below them and the live exposure they carry, then add CAF and GRC as the shared evidence base proves itself. Because every module runs on one engine, what you build for the first carries straight into the next.
For a prime the payoff is assurance that reaches past the first tier. Every tier is assured rather than just the suppliers you contract directly, DCPP Cyber Risk Profiles are tracked in one place, flow-down runs on a single evidence base, and posture is monitored continuously rather than at the next bid.
A defence supplier answers to Def Stan 05-138, the DCPP risk profiles and often NIST SP 800-171 at once, and a prime will not accept evidence shaped only for one. E2ERisk maps a single body of assessment answers to every regime it touches, so a control proven once is reported against all of them.
