E2ERisk helps civil nuclear organisations manage supplier assurance, cyber evidence, regulatory scrutiny and sovereign deployment in one controlled evidence model - built for sensitive assurance environments where evidence control matters.
The sector operates under ONR scrutiny and the highest expectations for classification, personnel control and auditable evidence. Supplier risk, the handling of sensitive information and the deployment of any assurance tooling all have to satisfy a regulator that expects precision, not marketing.
E2ERisk is built for that environment: sovereign deployment in your own tenant or fully air-gapped, customer-managed keys, an append-only audit trail and supplier-assurance evidence mapped to the ONR SyAPs expectations. See the security model →
Civil nuclear sits under some of the most demanding regulation in the country. The ONR's Security Assessment Principles set the bar for how licensees and their supply chains protect sensitive nuclear information and technology, and the evidence behind any claim has to withstand regulatory scrutiny rather than a supplier's say-so.
That extends to the assurance tooling itself: anything handling OFFICIAL-SENSITIVE supply-chain evidence has to be deployable on sovereign ground, with the licensee in control of both the data and the keys.
Every supplier follows the same path, from the moment it is engaged through to continuous monitoring long after sign-off. How deep the assessment goes is set by the sensitivity of the information and the role the supplier plays, so a regulated team concentrates its effort on the suppliers that genuinely matter to nuclear security.
Regulated assurance, deployable in your own sovereign environment.
The obligations do not change; what changes is whether the evidence is defensible and where it lives. Run on spreadsheets and email, deployment drifts offshore, SyAPs is interpreted differently by each assessor, and sensitive evidence ends up scattered across inboxes.
| What you do | Spreadsheets + email | E2ERisk |
|---|---|---|
| Deployment | Shared SaaS, data offshore | Sovereign: your tenant, your residency |
| SyAPs alignment | Interpreted per assessor | Consistent and control-level |
| Supplier evidence | Scattered | One defensible base |
| Sensitivity | Handled ad hoc | Sensitivity classified and access-controlled |
| Regulator request | A scramble | A current, defensible pack |
| Next assessment | From scratch | A review of what is already there |
The result is regulated assurance you can actually defend: consistent against SyAPs, held in your own tenant, and ready the moment the ONR or your board asks.
Most nuclear licensees start with Supplier Assurance and CAF Assessment: the regulated supply chain and the control-level evidence behind it, then add Secure by Design and Business Resilience 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 nuclear licensee the payoff is regulated assurance that never leaves sovereign ground. The platform deploys in your own tenant, supplier assessment is aligned to ONR SyAPs, the CAF is assessed natively at v4.0, and every regime draws on one defensible evidence base.
A licensee answers to the ONR's SyAPs, the Nuclear Industries Security Regulations and the CAF at once, and an assessor for one will not accept evidence shaped only for another. E2ERisk maps a single body of assessment answers to every regime it touches, so a control proven once is reported against all of them.
