Editorial independence: aicompliancevendors.com does not accept vendor payment for inclusion or ranking. Every pick below is editor-selected against the criteria stated on this page, and every factual claim is traceable to a cited public source.
Top picks: Credo AI — Enterprises requiring deep policy automation and agentic AI governance; Holistic AI — Organizations needing unified discovery, testing, and governance in one platform; IBM watsonx.governance — Large enterprises governing diverse model portfolios with IBM ecosystem integration. Plus 5 more vendors reviewed below. Last updated April 21, 2026; every entry cites public sources.
How we decided which vendors qualify for inclusion.
Documented support for at least one major regulatory framework (EU AI Act, NIST AI RMF, ISO 42001).
AI system inventory and registry capabilities — not only model performance monitoring.
Risk assessment workflows at the individual AI system level.
Compliance evidence generation and audit trail functionality.
Actively maintained with product updates within the 12 months preceding April 2026.
Evaluated against publicly documented capabilities on vendor product pages. Analyst recognition noted but not used as primary ranking criterion. Prioritized governance workflow depth, regulatory framework coverage, and deployment flexibility.
Credo AI's AI Agent Registry maps dependency graphs across agents, sub-agents, models and tools. Pre-built policy packs for the EU AI Act, NIST AI RMF, ISO 42001 and SOC 2 come with automated evidence generation and audit trails, and GAIA is an AI-powered governance assistant. Credo AI was named a Leader in The Forrester Wave: AI Governance Solutions, Q3 2025, with the highest possible scores in 12 criteria (per Credo AI). It publishes no prices.
Strengths
AI Agent Registry maps agents, sub-agents, models and tools.
Pre-built policy packs for EU AI Act, NIST AI RMF, ISO 42001, SOC 2.
Leader in The Forrester Wave: AI Governance Solutions, Q3 2025.
Limitations
No public pricing.
No self-serve trial documented; evaluation starts with a "Talk to an Expert" call.
Holistic AI's Identify-Protect-Enforce architecture integrates testing with governance more tightly than platforms separating MLOps from compliance documentation. Protect runs 40+ tests for bias, hallucination, privacy and robustness, red-teams for prompt injection and jailbreaks, and monitors drift in production. Its April 2026 newsletter announced runtime agentic monitoring, and Holistic AI says Gartner named it a Challenger in its first Magic Quadrant for AI Governance Platforms (June 2026). No public pricing.
Strengths
Unified discover-protect-enforce architecture across bias, security, and compliance.
40+ automated tests for bias, hallucination, privacy and robustness, plus red teaming.
Challenger in the 2026 Gartner Magic Quadrant for AI Governance Platforms (per Holistic AI).
Limitations
No public pricing; demo request only.
Platform breadth may exceed early-stage governance program needs.
IBM watsonx.governance publishes its prices (checked October 2026): a free 14-day trial; Model Management from $0.64 pay-as-you-go (IBM doesn't state the unit); and Risk & Compliance Basic from $3,500 a month and Advanced from $6,450 a month, each for one instance, one module and one concurrent user. It shows the EU AI Act, NIST AI and ISO 42001 among supported frameworks and AWS and Azure among its integrations. IBM says Gartner named it a Leader in the 2026 Magic Quadrant for AI Governance Platforms. G2 lists a 4.3 out of 5 rating from 83 reviews.
Strengths
Published pricing: Model Management from $0.64 pay-as-you-go; Risk & Compliance Basic from $3,500/month.
Free 14-day trial; 30-day trial on Model Management.
Leader in the 2026 Gartner Magic Quadrant for AI Governance Platforms (per IBM).
Limitations
Risk & Compliance entry plans include one module and one concurrent user.
IBM does not state the billing unit for the $0.64 Model Management price.
OneTrust AI Governance connects legal, risk, compliance, and security teams around a shared AI inventory. Its primary value for OneTrust customers is consolidation — one platform for privacy, GRC, and AI governance. Multi-framework coverage: EU AI Act, NIST AI RMF, ISO 42001. Buyers not already in the OneTrust ecosystem should compare governance depth against purpose-built alternatives.
Strengths
Integrates AI governance with existing OneTrust privacy and GRC workflows.
EU AI Act, NIST AI RMF, and ISO 42001 multi-framework coverage.
Established enterprise compliance infrastructure.
Limitations
No public pricing.
Less differentiated for buyers without existing OneTrust deployments.
Collibra AI Governance leverages its established data governance platform to provide AI use case governance with full data lineage. For organizations already using Collibra, extending maintains a single lineage and metadata model. Most valuable for Collibra ecosystem users; limited standalone value for non-Collibra organizations. Enterprise-only pricing.
Strengths
Full data-to-model lineage for existing Collibra customers.
Automated compliance documentation with trusted data foundations.
Established enterprise data governance track record.
ServiceNow AI Governance provides AI lifecycle governance within ServiceNow's workflow engine. For organizations standardized on ServiceNow for ITSM and risk, governance as a native module avoids a separate vendor relationship. Foundation/Advanced/Prime tiers with AI tokens; contact sales for pricing.
Strengths
Native AI governance within existing ServiceNow workflows.
Connects strategy, security, legal, risk, and compliance teams.
No separate tool onboarding for ServiceNow shops.
Limitations
Only valuable for existing ServiceNow organizations.
Monitaur focuses on full-lifecycle AI governance for regulated enterprises, bundling software with advisory services — a differentiator for organizations needing implementation support. Financial services and insurance positioning aligns with SR 11-7 model risk management. Enterprise-only pricing bundled with advisory.
Strengths
Software-plus-advisory model for teams needing implementation support.
Financial services and insurance specialization.
Full-lifecycle governance focus.
Limitations
Advisory bundling increases total cost vs self-serve alternatives.
DataRobot is the only platform in this list combining AI model development (AutoML, LLM deployment) with governance in a single system. For teams building models in DataRobot, governance is native to the development workflow. Enterprise-only pricing with free trial available. Governance capabilities are strongest for DataRobot-built models.
Strengths
Governance native to DataRobot model development workflow.
Covers classic ML and GenAI governance in one platform.
Free trial available for evaluation.
Limitations
Governance value is primarily for models built within DataRobot.
Criteria-based recommendations for the most common shortlist scenarios.
For multi-agent AI deployments, look at Credo AI's agent registry and policy automation. For unified testing and governance, Holistic AI's integrated approach avoids tool sprawl. For organizations already on IBM, ServiceNow, OneTrust, or Collibra, extending those platforms is faster. For regulated financial services needing software plus advisory, Monitaur's bundled model fits better.
What we did not include
Transparency about exclusions.
Modulos AI, Scrut Automation, Vanta, and Drata primarily position as compliance automation platforms with AI governance modules, covered in ISO 42001 and NIST AI RMF collections. FairNow is now sold by Optro (formerly AuditBoard) as Optro AI Governance, which lists 25+ frameworks; we have not yet evaluated it under the Optro name (checked October 15, 2026).
Frequently asked
What is the difference between an AI governance platform and an MLOps platform?+
MLOps platforms focus on the technical lifecycle — building, deploying, and monitoring models for performance and accuracy. AI governance platforms focus on risk, policy, regulatory compliance, and accountability. For compliance-driven procurement, AI governance platforms are the relevant category.
Does Gartner cover AI governance platforms in a Magic Quadrant?+
Yes. Gartner published its first Magic Quadrant for AI Governance Platforms on June 16, 2026. Before that it covered the category in a Market Guide for AI Governance Platforms (November 2025), which lists representative vendors without Leader/Challenger placement. Vendors report their own placements in the Magic Quadrant: IBM as a Leader, Holistic AI as a Challenger and OneTrust as a Visionary. Forrester published a Wave for AI Governance Solutions in Q3 2025.
