What to Look for in an AI Governance Platform

Before evaluating specific tools, it helps to understand the core capabilities that define an effective AI governance platform:

• AI Discovery and Inventory: The ability to automatically detect and catalogue all AI tools in use across your organisation, including shadow AI and unsanctioned tools.
• Policy Management: Tools for creating, distributing, and enforcing AI acceptable use policies across teams and departments.
• Data Protection: Real-time monitoring and prevention of sensitive data leakage through AI interactions, including prompt scanning and content classification.
• Risk Assessment: Frameworks for evaluating and scoring the risk of individual AI tools and use cases.
• Compliance Reporting: Automated reporting capabilities that map AI usage to regulatory requirements (GDPR, HIPAA, EU AI Act, etc.).
• User Activity Monitoring: Visibility into how employees interact with AI tools, what data they share, and whether they comply with policies.
• Integration Ecosystem: Connectivity with your existing security stack — SIEM, CASB, identity providers, and endpoint management tools.

Top AI Governance Platforms in 2026

The AI governance market has matured significantly, with platforms ranging from comprehensive enterprise suites to focused point solutions. Here are the leading contenders:

Aona

Aona is a purpose-built AI governance platform designed for security-conscious organisations. It combines AI discovery, real-time data protection, policy enforcement, and compliance reporting in a single platform.

• Best for: Mid-market to enterprise organisations that need comprehensive AI governance with strong data protection capabilities.
• Key strengths: Real-time prompt monitoring, semantic data classification, shadow AI discovery, and granular policy controls. Strong focus on preventing sensitive data leakage through AI interactions.
• Deployment: Cloud-based with API integrations. Quick deployment with minimal infrastructure changes.

Microsoft Purview AI Hub

Microsoft Purview has extended its compliance and data governance capabilities to cover AI workloads, particularly for organisations heavily invested in the Microsoft ecosystem.

• Best for: Enterprises already using Microsoft 365 and Azure that want integrated AI governance within their existing compliance infrastructure.
• Key strengths: Deep integration with Microsoft Copilot, Azure OpenAI Service, and Microsoft 365. Leverages existing Purview data classification and DLP policies.
• Limitations: Strongest coverage is within the Microsoft ecosystem. Third-party AI tool governance requires additional configuration.

Robust Intelligence (now Cisco)

Acquired by Cisco, Robust Intelligence focuses on AI model validation, security testing, and runtime protection. It is particularly strong in technical AI risk management.

• Best for: Organisations building custom AI models that need rigorous model validation, adversarial testing, and runtime monitoring.
• Key strengths: Model stress testing, adversarial robustness evaluation, continuous model monitoring, and automated compliance validation.
• Limitations: More focused on model-level governance than end-user AI usage governance. Less suited for organisations primarily concerned with shadow AI and employee AI usage.

Credo AI

Credo AI provides an AI governance platform focused on responsible AI practices, policy compliance, and regulatory alignment.

• Best for: Organisations that need strong policy management and regulatory mapping capabilities, particularly for EU AI Act compliance.
• Key strengths: Comprehensive policy library, regulatory mapping (EU AI Act, NIST AI RMF), AI risk assessment frameworks, and governance workflow automation.
• Limitations: Less focused on real-time data protection and prompt-level monitoring. Stronger on governance process management than technical enforcement.

Securiti AI

Securiti extends its data security and privacy platform to cover AI governance, with particular strength in data-centric AI security.

• Best for: Organisations with complex data landscapes that need unified data security, privacy, and AI governance.
• Key strengths: Data discovery and classification across AI pipelines, consent management, cross-border data transfer compliance, and integration with existing data security infrastructure.
• Limitations: Broad platform that covers many areas — organisations seeking focused AI governance may find it more complex than needed.

How to Choose the Right Platform

Selecting an AI governance platform depends on your organisation's specific needs, existing infrastructure, and primary use cases. Consider these factors:

1. Primary concern: If your main worry is employees leaking sensitive data through AI tools (shadow AI), prioritise platforms with strong real-time monitoring and data protection like Aona. If your focus is on model-level governance, consider Robust Intelligence.
2. Existing stack: If you are a Microsoft shop, Purview AI Hub offers the path of least resistance. If you have a diverse tool environment, choose a platform-agnostic solution.
3. Regulatory requirements: If EU AI Act compliance is a priority, evaluate Credo AI's regulatory mapping capabilities. For HIPAA, ensure the platform supports healthcare-specific controls.
4. Deployment complexity: Consider the implementation timeline and resource requirements. Cloud-native platforms like Aona typically deploy faster than on-premise solutions.
5. Budget: AI governance platforms range from usage-based pricing to enterprise contracts. Factor in not just the platform cost but also implementation, training, and ongoing management resources.

Emerging Trends in AI Governance Tooling

The AI governance market is evolving rapidly. Key trends to watch in 2026 and beyond include:

• Convergence with CASB and DLP: AI governance capabilities are being integrated into broader cloud security platforms, blurring the lines between traditional security and AI-specific governance.
• Automated compliance: Platforms are increasingly offering automated mapping of AI usage to regulatory requirements, reducing the manual effort required for compliance reporting.
• Agent governance: As AI agents become more autonomous, governance platforms are evolving to monitor and control agent-to-agent interactions, not just human-to-AI interactions.
• Supply chain AI risk: Tools are emerging to assess AI risk in your vendor and supply chain relationships, extending governance beyond your own organisational boundaries.
