How we chose the best TPRM platforms for supply chain due diligence

You need a platform that goes beyond onboarding questionnaires. We evaluated each solution across the full third-party lifecycle and how well it supports audit-ready programs regulators expect.

  • Due diligence depth: Can the platform screen for sanctions, adverse media, PEPs, beneficial ownership, and ESG risks in one workflow?
  • Ongoing monitoring: Does the system flag risk changes between annual reviews?
  • Workflow automation: How much of the assessment and escalation process runs without manual intervention?
  • Scalability: Can the platform handle 5,000 third parties as effectively as 500?
  • Connected compliance data: Does third-party risk connect with disclosures, incidents, and investigations?

The 6 best TPRM platforms for enterprise supply chain due diligence

1. GAN Integrity: Best overall TPRM platform for enterprise due diligence

GAN Integrity stands apart because it connects third-party risk management with your broader ethics and compliance program in one platform. Where other tools stop at vendor screening, GAN Integrity links third-party data to employee disclosures, gift records, whistleblower reports, and investigation outcomes.

That connected approach matters. When you can see that the supplier flagged for sanctions exposure is also the one an employee disclosed a personal relationship with, you're operating with genuine intelligence. GAN Integrity's AI-powered due diligence automates screening across global watchlists and ESG risk indicators, cutting onboarding time by up to 70% based on client results at Clarios.

GAN Integrity features

  • End-to-end lifecycle management: Automated workflows from onboarding through monitoring and off-boarding
  • AI-powered risk screening: Screens against sanctions, PEPs, adverse media, forced labor, and ESG factors
  • Connected compliance data: Links third-party records with disclosures, conflicts of interest, and investigations
  • Supply chain mapping: Partnership with Sayari maps beneficial ownership and Nth-tier supplier relationships
  • Configurable workflows: Adapt risk thresholds and escalation rules to your governance requirements without IT projects

GAN Integrity pros and cons

Pros:

  • Unified platform connecting TPRM with ethics, disclosures, policies and investigations
  • Dedicated compliance expert support for program design
  • Configurable low-code platform adapts to regulatory changes without heavy IT investment

Cons:

  • Organizations focused exclusively on cybersecurity vendor risk may not need the full compliance suite
  • Initial configuration for complex multi-jurisdictional programs takes dedicated planning
  • Advanced supply chain mapping features require Sayari integration setup

2. OneTrust: Privacy-focused vendor risk assessments

OneTrust offers third-party risk management tied to data privacy and technology vendor risk. The platform includes structured onboarding, risk tiering, and assessment templates mapped to GDPR and CCPA. Non-privacy use cases can require additional configuration, and complex implementations often need professional services.

OneTrust pros and cons

Pros:

  • Extensive privacy-focused questionnaire library
  • Aligns vendor assessments with data protection regulations
  • Supports processor and sub-processor data handling tracking

Cons:

  • Non-privacy TPRM use cases require significant configuration
  • Complex implementations often need professional services
  • Limited native integration with enterprise risk programs

3. Diligent: Governance-aligned vendor screening

Diligent offers vendor screening and monitoring with alignment to corporate governance processes. The platform includes AI-powered risk triage and board-level reporting on vendor risk. Dashboard and report configuration requires technical support, and operationally complex TPRM environments may need additional tools for cyber and resilience risk.

Diligent pros and cons

Pros:

  • Aligns third-party risk with corporate governance and board reporting
  • Offers AI-powered vendor screening for risk triage
  • Suited to organizations with established governance structures

Cons:

4. Certa: No-code lifecycle automation for procurement

Certa focuses on third-party lifecycle automation with a no-code platform geared toward procurement teams. The tool supports onboarding, assessments, and monitoring workflows that teams can configure independently. Compliance-specific due diligence for sanctions, ABAC, and ESG may require add-on integrations.

Certa pros and cons

Pros:

  • No-code configuration allows procurement teams to build workflows independently
  • AI features reduce time on document review and categorization
  • Vendor self-service portals reduce data collection overhead

Cons:

  • Compliance-specific due diligence requires additional integrations

  • Primarily procurement-focused with fewer ethics and compliance features

5. SAI360: GRC-integrated risk management with training

SAI360 offers third-party risk management as part of a broader GRC platform, connecting vendor assessments with compliance training and policy management. Pre-built risk frameworks reduce initial setup time. The interface has not been updated recently, and advanced TPRM workflows can require significant configuration.

SAI360 pros and cons

Pros:

  • Integrates third-party risk with training and policy management
  • Pre-built frameworks reduce setup time for common risk domains
  • Covers multiple GRC functions beyond vendor risk

Cons:

  • Interface and user experience have not been updated recently
  • Advanced TPRM workflows require significant configuration
  • Reporting customization is limited compared to purpose-built TPRM platforms

6. NAVEX: Ethics and compliance with risk-rated screening

NAVEX offers vendor screening through its RiskRate product, with risk scoring and categorization. The platform connects with NAVEX's broader ethics and compliance suite, including hotline management. TPRM capabilities are narrower than purpose-built third-party risk platforms, and supply chain mapping requires add-ons.

NAVEX pros and cons

Pros:

  • RiskRate includes automated risk scoring for vendor screening
  • Connects vendor risk data with ethics and hotline management
  • Suited to organizations already using the NAVEX compliance suite

Cons:

What should you look for in a TPRM platform for supply chain due diligence?

Screening checks tell you whether a third party appears on a watchlist today. A TPRM platform built for supply chain due diligence needs to map ownership structures, track risk across sub-tiers, and connect that data with internal compliance activity.

Questions worth asking before you commit:

  • Can you trace beneficial ownership beyond your direct third parties?
  • Does the system connect due diligence findings with employee disclosures and investigations?
  • How does the platform handle regulatory changes across jurisdictions without IT intervention?

How do enterprise TPRM programs scale without adding headcount?

Scaling a third-party risk program from 500 to 5,000 relationships is where platforms prove their worth. The honest answer is that headcount alone won't solve it. Automation of low-risk approvals, configurable risk thresholds, and tiered assessment workflows allow compliance teams to expand coverage without proportionally expanding the team.

GAN Integrity's Integrity Essential addresses this directly by automating onboarding, risk assessments, and off-boarding workflows so your team focuses on the third parties that need attention.

FAQs about best TPRM platforms for enterprise due diligence

What is a third-party risk management platform?

A third-party risk management platform is software that helps you identify, assess, monitor, and manage risks from external vendors and suppliers. GAN Integrity goes further by connecting third-party risk data with your broader compliance program, including disclosures, training, and investigations.

How does GAN Integrity differ from other TPRM platforms?

GAN Integrity connects vendor risk management with ethics, disclosures, and investigation management in one platform. Where other tools treat third-party risk as an isolated function, GAN Integrity links supplier data with employee conduct records for a unified compliance picture.

Can a TPRM platform help with EU CSDDD compliance?

The EU's Corporate Sustainability Due Diligence Directive (CSDDD) requires organizations to identify and address human rights and environmental risks across supply chains. GAN Integrity's supply chain due diligence tools automate the screening and monitoring that CSDDD compliance demands.

What questions should you ask when evaluating TPRM platforms?

Focus on workflow automation depth, connected compliance data, scalability, and audit-ready reporting. Ask whether the platform traces Nth-tier supplier relationships and connects due diligence findings with internal compliance data like disclosures and incidents.
