Due Diligence Agent

Before a vendor can be assessed, a significant amount of coordination has to happen. Questionnaires need to be sent, responses tracked, documents collected, and missing information chased. None of this requires judgement, but all of it consumes time and creates delay, particularly when assessment volumes increase or vendors respond slowly.

The LuminIQ Due Diligence Agent executes this work automatically when an assessment is triggered. Questionnaires are issued, evidence is collected, follow-ups happen without manual effort, and submissions are scored against your framework. Human teams focus on evaluating risk and deciding next steps, not managing the mechanics of the assessment process.

What It Reviews

The agent automatically reviews due diligence questionnaires and supporting evidence as soon as they are submitted, applying your framework without backlog so human teams review only completed or flagged assessments.

  • Questionnaire responses: Reviews completed assessment questionnaires against your defined framework, identifying gaps, inconsistencies, or unanswered questions.

  • Supporting evidence: Reviews submitted documents such as insurance certificates, compliance attestations, SOC reports, and financial statements for presence and validity.

  • Risk scoring inputs: Assesses questionnaire responses and evidence completeness to calculate risk ratings based on your criteria.

  • Assessment readiness: Identifies which assessments meet baseline requirements and which require human review due to elevated risk or missing information.

Who this is for

This agent is for compliance, risk, and procurement teams responsible for running vendor assessments at scale. It is designed for organisations where due diligence timelines are stretched by manual coordination rather than risk complexity.

It supports teams that want assessments to progress without constant follow-up, and leaders who need predictable, repeatable vendor risk processes without adding headcount or compromising oversight.

Manual vs automated agent execution

Before:

Before using the agent, due diligence assessments depend on manual coordination. Teams must send questionnaires, monitor responses, collect documents, and chase missing information. This work happens before any risk judgement can be made and consumes significant time, especially when vendors respond slowly or partially.

  • Assessment timelines are driven by follow-up effort, not risk complexity
  • Evidence arrives in fragments, increasing coordination overhead
  • Teams spend time chasing vendors rather than reviewing submissions
  • Risk scoring is delayed until all inputs are manually gathered
  • Review backlogs grow as assessment volume increases

After:

After the agent is in place, the due diligence process runs automatically from the moment an assessment is triggered. Inputs are collected, tracked, and evaluated without manual coordination.

  • Questionnaires and evidence requests are issued immediately
  • Missing responses are followed up automatically
  • Submissions are assessed as they are completed
  • Low-risk assessments progress without delay
  • Human effort is focused on evaluating risk, not managing the process

Configuration options

The Due Diligence Agent is configurable to reflect how your organisation assesses vendor risk, ensuring assessments run automatically while still matching your internal policies and thresholds.

  • Risk tiering rules: Define vendor risk tiers that determine which questionnaires and evidence are required.
  • Questionnaire selection: Configure which assessment questionnaires are sent based on vendor type or risk level.
  • Evidence requirements: Specify which supporting documents are required for different vendors, such as insurance certificates, compliance attestations, or financial statements.
  • Scoring framework: Define how questionnaire responses are scored and how overall risk ratings are calculated.
  • Review routing: Configure how completed assessments are routed based on risk level, so higher-risk results receive focused human review.

Security & Compliance

All agent actions are logged, including questionnaires sent, follow-ups issued, documents collected, and scores calculated. Assessment data is handled within Gatekeeper’s secure environment with access controls aligned to your permission settings. This provides a clear audit trail showing consistent execution of your third-party risk process.

The Due Diligence Agent is part of LuminIQ, Gatekeeper’s AI engine for third-party lifecycle management. All agent actions are logged with complete audit trails. The agent operates within your configured permissions and routing rules—it doesn’t make decisions outside the parameters you set. Data handling follows Gatekeeper’s enterprise security standards, including SOC 2 Type II compliance and GDPR requirements.
