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.

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

- Aligns vendor assessments with data protection regulations
- Supports processor and sub-processor data handling tracking
Cons:
- Non-privacy TPRM use cases require significant configuration

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:
- Dashboard configuration requires technical support

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:

- 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

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:

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:
- TPRM capabilities are narrower than purpose-built platforms

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.
