ISO 37001 bribery risk assessment: how to do one, step by step
How to carry out the bribery risk assessment ISO 37001:2025 requires in clause 4.5: the units of analysis, eight steps with their records, a worked contractor example, what the certification body tests and how to keep the assessment current.
Key points
- ISO 37001:2025 places the bribery risk assessment in clause 4.5, inside the context of the organisation, so every later control has to trace back to it.
- The assessment identifies the bribery risks you can reasonably anticipate, analyses and prioritises them, and rates the controls you already run against each one.
- Its ratings decide who gets due diligence and who is asked for anti-bribery commitments: the standard applies both to categories above a low bribery risk.
- Assess by country, business line, transaction type and category of business associate, not by department, and write down the reasoning behind every rating.
- It is a living record: review it on a regular cycle and whenever the business changes in a way that shifts exposure.
What does ISO 37001 ask of a bribery risk assessment?
An ISO 37001 bribery risk assessment is a documented study of where bribery could realistically happen in or around your organisation, how serious each exposure is, and how well your current controls cover it. Clause 4.5 of ISO 37001:2025 requires you to identify the bribery risks you can reasonably anticipate, analyse and prioritise them, evaluate whether the existing controls are suitable and effective, and keep the result under review. Because measures must be proportionate, its output sets how strict your due diligence, financial and non-financial controls and training need to be.
Unlike a general enterprise risk register, it looks at bribery in both directions, bribes offered on your behalf and bribes offered to your people, and it is built on the facts gathered under clause 4.1, which in the 2025 edition include your locations and sectors, your controlled entities, your dealings with public officials and, now explicitly, whether climate change is a relevant issue for you.
The units of analysis: where bribery risk actually sits
Bribery risk does not live in an org chart; it lives where money, discretion and a counterparty meet. Sterling's recommended approach is to break the business into four units and assess the combinations that exist in practice.
- Countries and locations. Where you operate, sell, source or obtain permits, including places where you have no office but rely on an agent.
- Business lines and activities. Tendering, licensing and permits, customs clearance, sponsorships, recruitment, land acquisition, inspections, collections.
- Transaction types. Commissions, success fees, facilitation-style requests, cash payments, discounts and rebates, charitable donations, hospitality for officials.
- Categories of business associate. Sales agents, distributors, joint-venture partners, subcontractors, consultants, customs brokers, suppliers, and the controlled entities within your group.
Name the roles that approve payments, award contracts, deal with inspectors or carry sales targets too: clause 7.2.2 ties checks on higher-risk roles and the review of incentives back to what the assessment finds.
How to do a bribery risk assessment, step by step
The sequence below scales from one site to a group; each step leaves a record the auditor can sample.
| Step | What you do | What it leaves on file |
|---|---|---|
| 1. Agree the method | Choose likelihood and impact scales, the definition of "low" risk, and who approves the ratings; top management signs the method off | An approved method note with scales and rating rules |
| 2. Gather the facts | Pull the clause 4.1 and 4.2 inputs: markets, entities, public-official touchpoints, interested parties, past incidents and speak-up cases | A context summary with the sources named |
| 3. Identify scenarios | Workshops with sales, procurement, finance, operations and legal; write each risk as a concrete scenario | A scenario list, one line per realistic route to a bribe |
| 4. Rate the inherent risk | Score likelihood and impact before controls, using the agreed scales and giving the reason for each score | Inherent ratings with written rationale |
| 5. Evaluate existing controls | Map the controls already running to each scenario and test whether they are designed well and actually operate | A control map with evidence references and an effectiveness view |
| 6. Rate the residual risk and prioritise | Re-score after controls; rank the results and mark which categories sit above low risk | A prioritised register and the list of higher-risk categories |
| 7. Decide actions | Link each priority to a treatment under clause 6.1: new controls, due diligence tiers, training, contract clauses, or exit | An action plan with owners and dates |
| 8. Approve and schedule review | Present to top management and inform the governing body; set the review cycle and the triggers for an early review | Approval record and a review calendar |
Write scenarios as sentences an auditor can test: "A customs broker in country X pays an inspector to release delayed shipments and bills us as 'expediting fees'." A good scenario names who pays, who receives, the advantage sought and how the money is disguised.
Worked example: a mid-sized engineering contractor
This illustration is a composite, not a client. Picture a contractor with its head office in one country, project sites in two others, around a dozen sales agents, and a steady flow of public-sector tenders.
| Scenario | Inherent | Controls in place | Residual | Consequence for the system |
|---|---|---|---|---|
| A sales agent passes part of a success fee to a tender evaluator | High | Standard agency contract; commissions approved by the sales director alone | High | Enhanced due diligence on all agents, second approval for commissions, anti-bribery commitments in every agency contract |
| A site manager pays an official to speed up a work permit | High | Petty cash with monthly reconciliation | Medium | Cash limits on sites, a written refusal script, targeted training for site managers |
| A subcontractor offers hospitality to a project engineer to secure variations | Medium | Gifts and hospitality rule exists but no register | Medium | Register with thresholds and approvals, declarations from engineers who sign variations |
| A donation to a local charity linked to a permitting authority | Medium | Donations approved by the managing director | Low | Keep current control; add a check of links to officials before approval |
Notice what the table decides. Agents and permit-heavy site work land above low risk, so they receive due diligence under clause 8.2 and commitments under clause 8.6. Due diligence tiers are covered in the guide to due diligence on business associates, and the register in the guide to gifts, hospitality and donations.
What the certification body looks for
The certification body's auditors usually start from the assessment and then walk forwards into operations. Expect them to pick a high residual risk and ask to see the control that answers it working in a live file: an agent's due diligence pack, a commission with two approvals, a register entry that was refused.
They will check that the method was approved, that ratings carry reasons, that existing controls were evaluated rather than assumed, and that the assessment was reviewed when something changed, such as a new market, an acquisition, a new category of intermediary or a reported concern. The anti-bribery function's review under clause 9.4 is the natural place for that evidence. For the audit stages themselves, see the ISO 37001 certification process.
Mistakes that weaken the assessment
- A generic template. Rows copied from another company name no real country, partner or payment type, and the auditor spots it within minutes.
- Only outbound bribery. Procurement, recruitment and approvals where your people could be bribed are left out.
- Controls taken on trust. A policy is counted as a control even though nobody checks whether it is followed, so residual ratings are too low.
- Everything rated medium. Nobody wants to write "high", so nothing is prioritised and due diligence has no clear population.
- No link to the controls. The assessment sits in a folder while due diligence tiers, thresholds and training plans are set by habit.
How Sterling runs the assessment
Scenarios your leadership recognises, ratings you can defend.
Sterling's expert and experienced consultants facilitate the workshops with your sales, finance, procurement and operations teams, test the controls you already have, and build the register in Effivity so that ratings link directly to due diligence tiers, the gifts register and training. The assessment then carries the ISO 37001 system through the certification body's audit. We ensure successful certification for our clients.

Set a fixed review cycle, commonly annual, and write down the events that force an earlier review: entering a country, appointing a new type of intermediary, a merger or joint venture, a change in law, a speak-up case or an internal audit finding. Record each review, even when no rating moves. Lessons from investigations and corrective actions under clause 10 should feed straight back into the scenarios. The wider structure of the standard is explained in ISO 37001 requirements explained.
ISO 37001 bribery risk assessment: questions buyers ask
How often should an ISO 37001 bribery risk assessment be reviewed?
Review it on a regular cycle, usually once a year, and earlier whenever a significant change alters your exposure. Typical triggers are new countries, new intermediaries, acquisitions and concerns raised.
Can we use our enterprise risk register instead of a separate bribery risk assessment?
Yes, if the register reaches the level of detail ISO 37001 needs. It must show bribery scenarios by country, activity, transaction type and business associate category, with existing controls evaluated against each.
Who should take part in the bribery risk assessment?
The anti-bribery function leads it, with people who know where money and discretion meet: sales, procurement, finance, operations, legal and HR. Top management approves the method and the results, and the governing body should be informed of the outcome.
Does the risk assessment decide which business associates need due diligence?
Yes. ISO 37001 applies due diligence and anti-bribery commitments to the categories your assessment rates above a low bribery risk, so the ratings define that population and the depth of checks each category receives.
What does "low bribery risk" mean in ISO 37001?
It is the level your own approved method defines as low, so set that definition with clear criteria, apply it consistently, and record why each category falls where it does, because the auditor will test that reasoning.
Should the assessment cover bribes offered to our own staff?
Yes. ISO 37001 covers bribery of the organisation and its personnel as well as bribery by them, so procurement decisions, recruitment, approvals and inspections your people carry out need scenarios of their own.
