Comparison Table
SecurityScorecard
specialistExternal cybersecurity ratings and third-party risk monitoring for suppliers and business partners.
Investigation case workflows that bundle evidence and decisions around scored vendor exposure, with traceable review history.
SecurityScorecard is designed around continuously updated risk scoring for business partners and suppliers, with case management workflows for investigation, remediation, and review sign-off. Evidence collection and reporting outputs are structured to support compliance reviews and internal audit needs, which helps when vendor assessments must be defended. Integration depth is a practical strength, with API access and exports that fit procurement, security, and compliance toolchains.

How to Choose the Right Third Party Due Diligence Software
We look for the difference between tools in how they handle third party due diligence evidence and decisions over time—especially for Evidence export format and Audit log completeness. Those choices usually determine how fast analysts can reuse results, prove what they did, and respond to internal reviews.
Evidence export format
Why it matters
Evidence export format matters when analysts need to share results across teams or with legal without rebuilding the whole file. It also affects how reliably your evidence survives handoffs and renewals.
How to check
Run a sample case and export the full record for review. Ask whether the export includes raw uploads plus the narrative outputs, and whether it stays readable outside the tool.
Audit log completeness
Why it matters
Audit log completeness matters because third party due diligence changes often come from new documents, edits, or re-approvals. You want a clear trail of who changed what and when.
How to check
In a demo, modify an item like a note or document and then revisit the timeline view. Confirm the log captures the actor, timestamp, and the specific field or attachment affected.
Workflow configuration depth
Why it matters
Workflow configuration depth separates tools that match your due diligence steps from those that force analysts into a generic flow. It also impacts how consistently teams collect required inputs.
How to check
Ask to configure a workflow with at least two stages and a manual review checkpoint. Then check whether the tool enforces required fields per stage and supports custom status labels.
API and automation surface
Why it matters
API and automation surface affects how much you can connect due diligence intake to your internal systems without brittle manual work. Strong automation also helps keep turnaround times consistent.
How to check
Request an API walkthrough for creating a record, attaching evidence, and updating outcomes. Verify there is a documented automation path (webhooks or an equivalent event mechanism) for status changes.
Entity data model and relationships
Why it matters
Entity data model and relationships matter because due diligence usually spans multiple entities and roles. If the schema is shallow, analysts spend time mapping relationships instead of evaluating evidence.
How to check
Create a scenario with at least one parent entity plus a related party, then add documents to each. Check whether the tool keeps roles and ownership-style relationships distinct and searchable.
Outcome versioning and rescreen records
Why it matters
Outcome versioning and rescreen records matter when analysts update a prior determination after new evidence. Without version history, it’s hard to explain why conclusions changed.
How to check
Trigger an update by adding a new document and changing an outcome. Verify the system preserves the prior outcome, links it to the new evidence, and shows what changed between versions.
Red flags
- Exports omit attachments or replace evidence with screenshots or summaries.
- The audit trail shows timestamps but not what fields or evidence changed.
- Workflow steps can’t enforce required inputs per stage or approvals.
Fit by situation
- If your analysts frequently rework cases with new documents, prioritize outcome versioning and rescreen records.
- If legal and procurement need to review findings outside the system, prioritize evidence export format.
- If you must connect intake and updates from other systems, prioritize API and automation surface.
