Pros & Cons
OneTrust
Pros
- Undisputed market leader in data privacy management — GDPR, CCPA, LGPD, PIPL compliance
- Cookie consent module handles technical complexity of ePrivacy compliance automatically
- DSAR automation processes data subject requests that would take hours manually
- Covers 100+ privacy regulations globally with automated regulatory mapping
- 14,000+ customers and $5.3B valuation validate market leadership and investment
Cons
- Pricing at $50,000-250,000+/year is enterprise-only territory
- Acquisitions (15+) created UI inconsistency between modules — feels like multiple products
- Privacy module is excellent but GRC, ethics, and ESG modules are less mature
- Implementation complexity is high with lengthy deployment timelines
- For SOC 2 or ISO 27001 only (without privacy focus), Vanta or Drata are simpler and cheaper
Diligent
Pros
- Used by 70% of Fortune 500 — the proven platform for public company governance
- Regulatory intelligence tracks changes across jurisdictions and maps to your obligations automatically
- Board portal is the most trusted and secure solution for director communications
- ESG reporting module maps to GRI, SASB, TCFD, CDP frameworks for disclosure compliance
- Modular architecture lets companies start with board governance and add GRC capabilities over time
Cons
- Pricing at $50,000-500,000+/year is exclusively for large enterprises with dedicated budgets
- Implementation takes months with professional services — not a self-serve platform
- Completely inappropriate for SMBs, startups, or first-time compliance programs
- The platform grew through acquisitions so module integration can feel inconsistent
- User interface is functional but dated compared to modern SaaS tools
