Your examiner has already read the standard. Since September 15, 2026, so has your internal audit function: The IIA's Third-Party Topical Requirement is now a mandatory part of its framework, and it sets a baseline for how auditors assess third-party governance, risk management and control processes. Whether your third-party risk program gets tested against a published yardstick is no longer the question. Whether you test it first is.
A gap assessment is how you do that. You pick the standard the audit will use, lay your program beside it, control by control and lifecycle stage by lifecycle stage, and write down every place where the two do not match. Then you rank the gaps by how much damage they do and how likely an auditor is to find them, and you fix the top of the list before the fieldwork letter arrives.
The seven steps below are built for a mature program at a regulated enterprise, where the standard is specific (the Interagency Guidance, DORA, NIST CSF 2.0, ISO 27001) and the evidence has to hold up. They end with a scoring matrix and a sample gap register you can copy into your own workbook.
The Short Answer
Pick the standard your auditor will use, inventory every third party and every control you run today, test each lifecycle stage against the standard with evidence rather than policy text, score each gap by severity and audit exposure, and hand the ranked list to named owners with dates. Done four to eight weeks before fieldwork, a gap assessment turns audit findings into closed remediation items.
What you need before a TPRM gap assessment
Six inputs, gathered first
A gap assessment with missing inputs produces a list of things you could not check. Gather these six before the first working session, because each one becomes either a column in the register or a gap you cannot score.
Budget the time too. For a program with a few thousand active third parties, plan on four to eight weeks from kickoff to signed report, with the heaviest week in control testing. Start closer than four weeks before fieldwork and you will be documenting gaps while the auditor documents the same ones.
Step 1 of 7
Who owns the gap assessment & who reviews it
One owner, independent eyes
A gap assessment belongs to the second line. The head of third-party risk, or the compliance or operational risk lead who owns the TPRM policy, runs it, because that person owns the controls and owns the remediation that follows. The business lines contribute as control operators and the owners of the relationships. Internal audit does not run it.
That last point matters more than it used to. A third party risk management audit performed by internal audit under The IIA's Third-Party Topical Requirement is the independent assessment. If audit runs your gap assessment, it is assessing its own work in the fieldwork that follows, and the Interagency Guidance separates the two for a reason: it calls for periodic independent reviews of the adequacy of third-party risk management processes as a distinct governance element from management's own oversight. Ask audit to agree the scope and the standard with you, then let them stay out of the room until the report is done.
| Role | In the gap assessment | Not in the gap assessment |
|---|---|---|
| Head of third-party risk (owner) | Scope, standard, workplan, scoring, the report and the remediation plan | Testing their own controls alone, signing off without a reviewer |
| Control operators (procurement, InfoSec, legal, resilience, business owners) | Walkthroughs, evidence, confirming how the control runs today | Deciding whether the gap is a gap |
| Independent reviewer (ERM, a second compliance lead, or an outside firm) | Challenges scoring, re-performs a sample of tests, signs the report | Writing the remediation plan |
| Internal audit | Agrees scope and standard, receives the final report | Running tests, drafting the report |
| Board risk committee | Receives the ranked gaps and the plan, approves resourcing | Operational detail |
Give the independent reviewer real work. A reviewer who only reads the finished report will approve it. A reviewer who re-performs five of the control tests and challenges the three highest scores will catch the gap you rated Medium because the fix was expensive.
Step 2 of 7
Pick the standard you will measure against
Measure against the examiner's yardstick
A compliance gap assessment is only as defensible as the standard it uses. Pick the one your auditor will pick, and when more than one applies, map them to a single control set so each gap is scored once. For most regulated enterprises the candidates are these.
| Standard | Who it binds | What it asks for |
|---|---|---|
| Interagency Guidance on Third-Party Relationships: Risk Management (FRB, FDIC, OCC, June 2023) | Banking organizations supervised by the three agencies, issued by the Federal Reserve as SR 23-4 and by the OCC as Bulletin 2023-17 | Risk management across five lifecycle stages (planning, due diligence and third-party selection, contract negotiation, ongoing monitoring, termination) plus oversight and accountability, independent reviews, and documentation and reporting, commensurate with risk and complexity |
| DORA, Regulation (EU) 2022/2554, applying from 17 January 2025 | EU financial entities and their ICT third-party service providers | ICT third-party risk managed as an integral component of ICT risk (Art. 28(1)), a register of information covering all ICT contractual arrangements (Art. 28(3)), a concentration risk assessment for critical or important functions (Art. 29), and minimum contractual provisions (Art. 30) |
| EBA Guidelines on outsourcing arrangements (2019) | EU credit institutions, investment firms and payment institutions | Governance of outsourcing arrangements, with stricter requirements where critical or important functions are outsourced. The EBA published final guidelines on non-ICT third-party risk on 18 September 2026 that will repeal them once applicable |
| NIST CSF 2.0, Govern function, Cybersecurity Supply Chain Risk Management (GV.SC), February 26, 2024 | Voluntary, widely adopted across US industry and by federal suppliers | Ten outcomes, GV.SC-01 through GV.SC-10, from an agreed program and roles through supplier prioritization by criticality, due diligence before contracting, monitoring over the relationship and provisions for after it ends |
| ISO/IEC 27001:2022 (published October 2022) | Any organization seeking certification, often a customer or contract requirement | Annex A supplier controls 5.19 through 5.23: information security in supplier relationships and agreements, the ICT supply chain, monitoring and change management of supplier services, and cloud services |
| The IIA Third-Party Topical Requirement (issued September 15, 2025, effective September 15, 2026) | Internal audit functions conforming to The IIA's Global Internal Audit Standards | A consistent approach to assessing the design and implementation of third-party governance, risk management and control processes |
Read the standard itself, not a summary of it. The Federal Reserve SR letter states that the guidance replaces each agency's earlier general guidance and applies to all banking organizations the Federal Reserve supervises. The guidance's own words set the test your program faces: due diligence "commensurate with the level of risk and complexity of the third-party relationship," ongoing monitoring "throughout the duration of a third-party relationship," and a sound methodology for designating which activities and third parties receive more comprehensive oversight. Those three phrases will reappear in your gap register as the criteria behind most of the findings.
Scope varies, so confirm it. The guidance applies to banking organizations, DORA to financial entities as defined in its Article 2, and the EBA guidelines to the institutions within the EBA's remit. A life sciences company or a defense prime with no banking charter still finds the Interagency Guidance useful as a description of what good looks like, and its auditors will say so. Where asset size, entity type or jurisdiction changes what binds you, settle it with counsel before the assessment starts, because changing the standard halfway through means rescoring every gap.
One more criterion belongs on the list if your program uses or plans to use AI in screening, pre-fill or adjudication. Auditors will ask how model outputs are reviewed, how rationale is recorded and who can override a decision. Certa's TPRM program AI readiness resource lays out the questions to answer before that conversation happens in fieldwork.
Step 3 of 7
Inventory your third party risk management program today
Count everything before judging anything
Before you test a single control, write down what the TPRM program actually consists of. Not the org chart version. The real one, with the spreadsheets, the shadow questionnaire in SharePoint, the monitoring feed nobody reads and the 400 vendors who were onboarded through an acquisition and never tiered.
Your inventory has two halves. The first is the third parties: every active relationship with business owner, inherent risk tier, the activity it supports and whether that activity is critical. The guidance leaves the definition of critical activities to each banking organization but names the characteristics: activities that could cause significant risk if the third party fails, that have significant customer impact, or that significantly affect financial condition or operations. DORA asks for the same distinction in its register of information, which must separate ICT services supporting critical or important functions from those that do not. If your inventory cannot answer "which of these are critical" in one query, that is your first gap.
Half two is the program itself. For each lifecycle stage, record the control, the system it runs in, the owner, the trigger and the evidence it leaves behind. A third party risk management program built over ten years rarely has one answer per row. Expect to find three intake paths, two tiering models and a monitoring process that differs by region.
- Third-party count by tier, by criticality and by business unit, with the number that have no tier at all
- Subcontractors and fourth parties recorded for critical relationships, which the guidance lists as appropriate to the risk presented
- Systems of record for intake, due diligence, contracts, monitoring and issues, and whether they reconcile to each other
- Control owners by lifecycle stage, with the date each procedure was last approved
- Open findings from prior audits and exams, with status and evidence of closure
- Reporting that reaches the board or its risk committee, with frequency and the last date sent
Count the systems too, because that number is itself a finding. One web-infrastructure leader that moved its program onto Certa consolidated from 6 systems to 1, bringing 8 to 10 teams onto one platform. Whatever the tool, an auditor who has to reconcile six exports to see one vendor's full picture will write that down, and so should you.
Step 4 of 7
Test controls across the third-party lifecycle
Evidence per stage, not policy per stage
This is the week that decides whether the assessment is worth anything. Testing means pulling a sample of real relationships and following each one through the lifecycle, checking what the control produced against what the standard requires. Reading the procedure and ticking "present" is a document review, and your auditor will not stop there either.
Sample by tier. Pull every critical relationship, a random ten percent of high-risk ones and a handful of low-risk vendors to confirm the light path stays light. For each sampled relationship, test the stages below. The structure follows the guidance's lifecycle, and Certa's TPRM framework components post walks through what each stage should contain in a well-built third party vendor risk management program.
| Lifecycle stage | What the standard asks | What to test, with evidence |
|---|---|---|
| Planning | Risk assessed before engaging, with greater consideration for critical activities (Interagency Guidance). Planning and due diligence before entering a relationship (GV.SC-06) | Intake record dated before contract signature, inherent risk assessment complete, critical designation documented. Evidence: the intake form and its timestamp |
| Due diligence & selection | Scope commensurate with risk and complexity, broadened when information warrants it. Supplier risks known and prioritized by criticality (GV.SC-04) | Tier-appropriate questionnaire and evidence on file, reviewer disposition with rationale, exceptions approved by the right authority. Evidence: the completed assessment and the approval record |
| Contract negotiation | Provisions matched to risk. DORA Art. 30(2) minimum terms for ICT services: service description and subcontracting conditions, locations, data protection, data return on exit, service levels, incident assistance, cooperation with authorities, termination rights and notice | Executed contract contains the required clauses for the tier and the regulation. Evidence: clause map against the contract text, not the template |
| Ongoing monitoring | Monitoring throughout the relationship, periodic or continuous, more frequent for critical activities, escalating material or repeat audit findings, financial deterioration, breaches and compliance lapses | Monitoring events logged on the schedule the policy sets, with escalations and responses recorded. Evidence: the monitoring log, alerts and the issue tickets they produced |
| Termination | Transition planned, data and access closed out. Provisions for after the agreement ends (GV.SC-10) | Offboarding checklist completed, access removed, data returned or destroyed with confirmation. Evidence: the closed offboarding record |
| Governance across all stages | Board oversight, periodic reporting, independent reviews, documentation (Interagency Guidance). An agreed program with roles and integration into enterprise risk (GV.SC-01 to GV.SC-03) | Board papers, review reports, the policy approval trail. Evidence: minutes and distributed reports, not the slide deck |
Record the result of each test as one of three outcomes: the control operated as the standard requires, it operated but below the standard, or it did not operate. Attach the evidence reference to every result. A gap with no evidence reference is an opinion, and opinions get argued down in the remediation meeting.
Step 5 of 7
Score each gap by severity & audit exposure
Two axes, one priority
A list of forty gaps with no ranking will be remediated in the order people find convenient. Score each one on two axes and let the product of the two set the order.
Severity asks how much harm the gap allows: what could go wrong with a critical third party if this control stays as it is. Audit exposure asks how likely the gap is to become a finding: whether the standard names the control explicitly, whether the auditor tested it last cycle, whether a prior finding already covers it. The matrix below is the scoring core of a gap assessment template you can reuse every cycle.
| Severity (down) x Audit exposure (across) | 4: Named in the standard & tested or found before | 3: Named in the standard | 2: Expected practice, not explicit | 1: Internal policy only |
|---|---|---|---|---|
| 4 Critical: control absent or failed for a critical relationship | 16 Fix before fieldwork | 12 Fix before fieldwork | 8 Fix this quarter | 4 Plan and schedule |
| 3 High: control below standard for critical or high-risk relationships | 12 Fix before fieldwork | 9 Fix this quarter | 6 Plan and schedule | 3 Plan and schedule |
| 2 Medium: control below standard for lower tiers, or inconsistent across regions | 8 Fix this quarter | 6 Plan and schedule | 4 Plan and schedule | 2 Track |
| 1 Low: documentation or timing gap with no control impact | 4 Plan and schedule | 3 Plan and schedule | 2 Track | 1 Track |
Two rules keep the scores honest. Severity is set by the control operator's domain reviewer and challenged by the independent reviewer, never by the owner who will have to fix it. Audit exposure is set from the standard's text and the prior reports, not from a feeling about what the examiner cares about this year. A repeat finding is automatically a 4 on exposure. Regulators treat an open repeat finding as evidence that management's response was not prompt or thorough, which is the language the guidance uses for what it expects.
Where the gap is about capability rather than a single control, score it against a maturity scale instead. A program that still screens by hand will not close a "continuous monitoring" gap with a procedure update. Certa's TPRM maturity model for AI gives a four-stage scale you can borrow for those rows, so the register shows the stage you are at and the stage the fix requires.
Step 6 of 7
Write the gap assessment report & remediation plan
A register, not a narrative
The gap assessment report has one job: to let a reader who was not in the room see every gap with score, owner and date on one page, and find the evidence behind any row in under a minute. Write it as a register with a short cover note, not as a twenty-page narrative. Auditors read registers. Boards read cover notes.
A cover note carries five things: the standard used and why, the sample tested, the count of gaps by priority band, the three gaps the committee has to decide on, and the independent reviewer's sign-off. Everything else lives in the register. A sample of the register, with illustrative rows, looks like this.
| ID | Gap | Standard reference | Severity | Exposure | Score | Owner & due |
|---|---|---|---|---|---|---|
| G-01 | 41 critical relationships have no documented fourth-party or subcontractor record | Interagency Guidance, documentation and reporting (inventory with subcontractors as appropriate to risk). DORA Art. 30(2)(a) subcontracting conditions | 4 | 4 (repeat finding, 2025) | 16 | Head of TPRM, before fieldwork |
| G-02 | Ongoing monitoring for Tier 2 vendors runs annually although the policy sets semiannual | Interagency Guidance, ongoing monitoring commensurate with risk and complexity | 3 | 3 | 9 | Vendor risk lead, this quarter |
| G-03 | No concentration assessment performed before contracting three cloud services supporting a critical function | DORA Art. 29(1), preliminary assessment of ICT concentration risk | 4 | 3 | 12 | CIO office and TPRM, before fieldwork |
| G-04 | Offboarding checklist exists but access removal is confirmed for 60 percent of terminated vendors sampled | Interagency Guidance, termination. NIST CSF 2.0 GV.SC-10 | 3 | 2 | 6 | IAM lead, plan and schedule |
| G-05 | Board reporting omits dependency on a single provider for multiple activities | Interagency Guidance, periodic reporting to the board including single-provider dependency | 2 | 3 | 6 | Head of TPRM, next board cycle |
| G-06 | Supplier agreements predating 2023 lack the information security clauses the policy requires | ISO/IEC 27001:2022 Annex A 5.20 | 2 | 2 | 4 | Legal, plan and schedule |
Your remediation plan is the same register with three more columns: the fix, the milestone dates and the evidence that will prove closure. Be specific about closure evidence at the time you write the plan. "Policy updated" closes nothing. "Semiannual monitoring events logged for every Tier 2 vendor in the two cycles after the change" closes G-02. Written this way, the report doubles as a third party risk management program template for the next cycle, because the standard, the controls and the evidence expectations are already mapped.
Where the fix is the audit trail itself, say what the trail must contain. Certa's platform captures every screen, adjudication and disposition with documented rationale, citations and timestamps, immutable and exportable on demand, and its By Exception model records the auto-dispositions alongside the rows that surfaced for review, so the reviewer sees the whole population and not just the exceptions. That is the shape of evidence an examiner can test: who decided, on what, when, and why.
Step 7 of 7
Build a third party risk management audit program for follow-up
Make the next one shorter
A gap assessment that happens once, in a panic, before one audit, will be repeated in a panic before the next. This last step turns it into a third party risk management audit program: a standing cycle with an owner, a calendar and a control library, so the next assessment starts from the last register instead of from a blank workbook.
- Keep the control library. Every control you tested, with its standard reference, test procedure and evidence expectation, becomes a row in a library maintained by the TPRM owner. New regulation maps to new rows, not a new assessment.
- Set the cadence by tier and by standard. Critical relationships and any control with an open finding get tested every cycle. Lower tiers rotate. DORA's annual reporting on the register of information and the board's periodic reporting under the Interagency Guidance set two fixed dates for the calendar already.
- Track remediation to closure evidence, not to status. A finding closes when the closure evidence named in the plan exists and the independent reviewer has seen it.
- Agree the standard with internal audit for the year ahead, so their Third-Party Topical Requirement work and your self-assessment use the same control set and the same sample logic.
- Report the trend. Count of gaps by band at each cycle, time to closure, repeat findings. A board that sees the count fall and the repeats disappear funds the program. One that sees a fresh crisis every year does not.
Transparency with the auditor is part of the program, not a concession. Sharing the register, the control library and the evidence index before fieldwork shortens the audit and moves the conversation from "what do you have" to "what are you fixing." Certa's audit transparency steps cover how to set that up without exposing the program to every passing question.
Common TPRM audit failures & how to avoid them
Where programs lose the exam
The common TPRM audit failures and how to avoid them below are the patterns that turn a clean-looking program into a findings letter. Most are visible in the gap register weeks ahead if you look for them.
- An inventory that does not reconcile. Procurement has 2,300 vendors, the TPRM tool has 1,900 and accounts payable has paid 2,700. The auditor finds the 800 in a morning. Fix: reconcile the three sources before the assessment and make the reconciliation a quarterly control.
- Criticality by spend. The payroll processor is Tier 3 because the contract is small. The guidance's characteristics of a critical activity say nothing about spend. Fix: re-tier on customer impact, financial and operational impact, and the consequence of failure, and document the methodology.
- Monitoring on the policy's calendar, not the vendor's risk. Annual reviews for everyone, including the critical ones. Fix: continuous or more frequent monitoring for higher-risk and critical relationships, with the escalation triggers the guidance names written into the procedure.
- Contracts that match the template, not the regulation. The clause library was last refreshed before DORA applied. Fix: map Article 30(2) and 30(3) to the clause library and run the clause map against executed contracts, not against the template.
- Findings closed on status. "In progress" for two cycles reads as unresolved to an examiner, whatever the ticket says. Fix: closure evidence defined in the plan, confirmed by the independent reviewer.
- No independent review at all. The second line assessed itself and the board got the summary. Fix: a named reviewer with a challenge log on every assessment, and internal audit's own cycle agreed in advance.
- Decisions without rationale. The vendor was approved with three open high findings and nobody wrote down why. Fix: documented rationale on every disposition, by whoever makes it, in the system of record.

TPRM gap assessment FAQ
Short answers, starting with what is a gap assessment and ending with whether a template can stand in for an assessor.
What Is a Gap Assessment in TPRM?
A TPRM gap assessment is a structured comparison of your third-party risk program against a chosen external standard, such as the Interagency Guidance, DORA or NIST CSF 2.0, that records every place where your controls fall short and ranks those gaps for remediation. It differs from a vendor risk assessment, which evaluates one third party. A gap assessment evaluates the program itself: governance, lifecycle controls and the evidence those controls leave behind.
How Long Does a TPRM Gap Assessment Take?
Four to eight weeks for a program with a few thousand active third parties, from kickoff to a signed report. Inventory and scoping take the first week or two, control testing takes the longest single stretch, and scoring, reporting and the remediation plan take the final week. Programs with a complete inventory and a control library from a prior cycle finish at the short end of that range.
Should an Internal Team or an Outside Firm Run the Assessment?
The second line should own it either way, because it owns the controls and the remediation. An outside firm earns its fee when the program has never been assessed against the standard, when the prior exam produced repeat findings, or when independence is in question because the TPRM team is small. For a mature program, an internal assessment with an independent reviewer from ERM or a second compliance lead is usually enough, with internal audit running its own separate review under The IIA's Third-Party Topical Requirement.
Can a Gap Assessment Template Replace an Assessor?
No. A template gives you the control list, the scoring matrix and the register format, which is most of the structure. It cannot pull a sample, read a contract against Article 30, or decide whether a monitoring log shows a control that operated or a control that was backfilled. Use the template to make the assessor faster and the output consistent across cycles, and keep a named person accountable for every score.
