Enhanced Due Diligence
Deeper diligence and senior sign-off for higher-risk relationships
Apply enhanced due diligence to higher-risk relationships — source-of-funds and source-of-wealth enquiry, ownership and control mapping, negative-news and reputational review, and senior sign-off — with a structured trail of the additional scrutiny applied and why. EDD is where the AML programme is tested hardest: high-risk customers, PEPs and complex structures demand more evidence, more challenge and a documented decision by someone senior enough to own it. OnyxOne Enhanced Due Diligence gives that scrutiny a defined structure so the depth of enquiry matches the risk, the evidence is gathered and preserved, and the approval to proceed is made and recorded at the right level of the firm.
How it works, visually
From onboarding and due diligence through review, approval and remediation to an evidenced, audit-logged outcome.
The problems this module solves
The operational realities that make this hard for compliance and risk teams today.
EDD is inconsistent and undefined
When a customer is flagged high risk, what happens next depends on the analyst. Some gather source-of-wealth evidence and challenge it; others tick a box. Without a defined EDD standard, the firm cannot show that higher risk actually triggered deeper scrutiny.
Source of funds and wealth is asserted, not evidenced
Source-of-funds and source-of-wealth statements are recorded as the customer gave them, with little corroboration and no structured trail of what was tested or accepted. At examination, the firm can show it asked the question but not that it challenged the answer.
Senior sign-off is informal and untraceable
Approval to onboard or retain a high-risk relationship happens by email or hallway conversation. The firm cannot demonstrate that a suitably senior person saw the full picture and made a documented decision to accept the risk.
The extra scrutiny is invisible after the fact
Even when thorough EDD is done, the evidence and reasoning are scattered across documents and inboxes. The additional work that justified proceeding cannot be produced as a single, coherent story when a regulator asks for it.
High-risk relationships are not kept under closer watch
A relationship that warranted EDD at onboarding drops back into the standard population afterwards, monitored no more closely than any other. The heightened risk that triggered enhanced diligence is forgotten until something goes wrong.
How OnyxOne addresses it
A defined EDD standard triggered by risk
When a customer meets your high-risk criteria — PEP status, high-risk geography, complex ownership, adverse media — an enhanced-due-diligence workflow is triggered with defined requirements. The depth of enquiry is matched to the risk by policy, not left to whoever picks up the case.
Structured source-of-funds and source-of-wealth enquiry
Source-of-funds and source-of-wealth are gathered, corroborated against supporting evidence and challenged within a structured enquiry. What was asked, what was provided, what was tested and what was accepted is captured as a coherent, defensible trail rather than a bare assertion.
Deeper ownership, control and reputational review
Ownership and control structures are mapped in more depth, connected parties examined, and negative-news and reputational review performed and recorded. The firm builds a fuller picture of who it is dealing with and the risks that come with them.
Senior sign-off, made and recorded at the right level
The decision to accept a high-risk relationship is routed to an appropriately senior approver who sees the full EDD picture and records a documented decision with conditions. Four-eyes review and escalation are enforced, so approval is deliberate and traceable rather than informal.
Higher-risk relationships kept under closer watch
Customers who required EDD are flagged for closer ongoing monitoring and more frequent review after onboarding, so the heightened risk that triggered enhanced diligence continues to be managed rather than forgotten once the relationship begins.

EDD triggering
Customers meeting your high-risk criteria are routed into the enhanced-due-diligence workflow automatically, with the extra requirements applied.
Evidence-completeness enforcement
The workflow requires the source-of-funds, source-of-wealth and other evidence your policy demands before a case can proceed to sign-off.
Senior approval routing
Completed EDD cases are routed to an approver of the required seniority under four-eyes review, with reminders until a decision is recorded.
Enhanced-monitoring hand-off
Approved high-risk relationships are automatically enrolled in enhanced ongoing monitoring with shorter review cycles.
Condition tracking
Conditions attached to a high-risk approval are tracked and reminded, so the terms of acceptance are actually met over time.
Where AI helps the analyst
Assistive, decision-support features that speed up the work on the record. Suggestions are always reviewable, and a person stays in control of every decision.
Source-of-wealth corroboration prompts
Suggests corroborating evidence and inconsistencies to probe in a source-of-wealth enquiry, which the analyst investigates and judges.
Adverse-media synthesis
Synthesises negative-news and reputational findings into a briefing for the analyst to review, verify and incorporate into the assessment.
EDD narrative drafting
Drafts the enhanced-diligence summary and recommendation from the captured enquiry and evidence, leaving the analyst and approver to edit and own it.
The enterprise workflow
A defined, end-to-end process with clear ownership at every stage.
Every result, decision and override is captured against the record it belongs to.
Trigger EDD

Ownership and connected parties are mapped in depth and negative-news and reputational review is performed and documented.
Assess & recommend
The analyst assesses the enhanced picture and prepares a recommendation to accept, decline or accept with conditions.
Senior sign-off
An appropriately senior approver reviews the full EDD picture and records a documented decision under four-eyes review.
Onboard & watch closely
Approved relationships are onboarded and flagged for enhanced ongoing monitoring and more frequent review over their life.
What your team gains
Scrutiny that matches the risk
A risk-triggered EDD standard ensures higher-risk relationships get genuinely deeper diligence, and the firm can show that they did.
Source of wealth challenged, not just asked
Structured enquiry captures what was tested and accepted, so the firm can demonstrate it challenged the answer rather than merely recording it.
Senior sign-off on the record
High-risk relationships are accepted by a suitably senior approver with a documented decision, so accountability is clear and traceable.
The extra work, told as one story
All the enhanced enquiry, evidence and reasoning sit on one trail, producible as a coherent narrative when a regulator asks.
High risk stays under closer watch
EDD customers are flagged for enhanced monitoring and more frequent review, so heightened risk keeps being managed after onboarding.
Consistent handling of PEPs and complex cases
Defined workflows mean PEPs, complex structures and high-risk geographies are handled to the same standard every time.
Industries it serves
Works with your existing systems
Described as capabilities — OnyxOne connects to the systems your deployment requires, configured per implementation.
- Draws PEP, sanctions and adverse-media results from the data providers configured for your deployment to inform the enhanced review
- Uses corporate registry and ownership data from your existing sources to support deeper ownership and connected-party mapping
- Continues seamlessly from the CDD module, inheriting the standard-diligence record and risk rating that triggered EDD
- Hands approved high-risk relationships to the ongoing-monitoring module with enhanced monitoring settings applied
- Routes evidence requests, escalations and senior approvals through your existing email and messaging tools
Security, compliance & reporting
Security & data handling
- Source-of-funds and source-of-wealth evidence and EDD records are encrypted in transit and at rest, with access governed by granular, role-based permissions.
- Sensitive personal, financial and reputational information is restricted to authorised roles and handled under strict need-to-know.
- Segregation of duties ensures the analyst performing EDD cannot also provide the senior sign-off where policy requires separation.
- Every enquiry, evidence item, challenge, finding and approval is written to an append-only audit trail.
- Data residency and retention for EDD records are configurable to your regulatory and privacy obligations.
Compliance support
- Supports enhanced-due-diligence (EDD) obligations for higher-risk relationships
- Underpins source-of-funds and source-of-wealth enquiry requirements

How to get the most from it
Trigger EDD by policy, not by instinct
Define the criteria that trigger enhanced diligence and let them fire automatically. Relying on an analyst to remember when EDD applies is where high-risk relationships slip through.
Challenge source of wealth, and record the challenge
Corroborate and test source-of-funds and source-of-wealth rather than accepting the customer's statement. Capturing what you challenged and why is what turns an assertion into evidence.
Match the approver to the risk
Route sign-off to someone senior enough to own the decision. A documented approval by the right person is the difference between deliberate risk acceptance and an informal nod.
Keep watching after you approve
Flag EDD customers for enhanced monitoring and shorter review cycles. The risk that justified enhanced diligence does not disappear the moment the relationship begins.
Questions, answered
When does enhanced due diligence apply?
EDD is triggered when a customer meets your high-risk criteria — for example PEP status, a high-risk geography, complex or opaque ownership, or significant adverse media. You define the criteria in policy and the workflow fires automatically when a customer meets them, so higher risk reliably triggers deeper scrutiny.
How does OnyxOne handle source of funds and source of wealth?
Both are gathered through a structured enquiry, corroborated against supporting evidence and challenged, with what was asked, provided, tested and accepted captured on the record. This lets the firm demonstrate it challenged the answer rather than simply recording the customer's statement.
How is senior sign-off handled?
The accept, decline or accept-with-conditions decision is routed to an appropriately senior approver who sees the full EDD picture, under four-eyes review and segregation of duties. The documented decision, its conditions and the approver are recorded on an immutable trail.
Does EDD continue after onboarding?
Yes. Customers who required EDD are flagged for enhanced ongoing monitoring and more frequent periodic review, so the heightened risk continues to be managed over the life of the relationship rather than being forgotten after approval.
Is OnyxOne deciding whether to accept a high-risk customer?
No. OnyxOne structures the enhanced enquiry and routes the decision, but a suitably senior person makes and owns the risk-acceptance decision. OnyxOne is decision-support software and a technology vendor; responsibility for EDD obligations remains with your firm.
