In order of how closely each one matches PVML.
BigID
4.4Not listed
vs PVML+0.4
Finds and classifies sensitive data across cloud, on-premise and AI systems.
- Sensitive data discovery and classification
- Data security posture management
- Governance for data inside AI systems
Covers AI systems alongside conventional data stores
Pricing is not published
Privacera
4.2Not listed

Data and AI governance covering access control, privacy compliance and security posture.

- GenAI governance controlling what models may retrieve
- Data security posture management (DSPM)
Open-standards foundation avoids proprietary policy lock-in
Enterprise scope and pricing are heavy for smaller teams
iDox.ai Guardrail
3.7Not listed
vs PVML−0.3
Watches what staff paste into AI tools and redacts the regulated data first.
- Automated redaction of PII, PHI and financial data
- Anonymisation that keeps documents usable
- Real-time guardrails on what staff send to AI tools
Guardrail enforces the AI data policy instead of merely publishing it
Redaction that misses is worse than none, so sampled verification is mandatory
Monitaur
4.0Not listed
vs PVMLSame
AI governance software for documenting, controlling and evidencing model decisions.
- Documentation of model lineage and approval
- Evidence that controls were applied
- Ongoing behaviour monitoring
Produces evidence rather than intentions
Pricing page returns a 404
Guardrail Technologies
3.8Not listed
vs PVML−0.2
An AI security platform that governs what enterprise AI systems can see, store, and reveal.
- AI Traffic Light scans AI-generated code and verifies the people behind dependent components
- AI Command Center gives centralized governance and behavioral controls over enterprise AI use
- Sits between enterprise data and AI applications as an access gatekeeper
Addresses AI governance and code-supply-chain risk together rather than as separate products
No public pricing; requires a scoped pilot or sales conversation to get a quote
Knostic
4.0Not listed
vs PVMLSame
Need-to-know access control for enterprise AI assistants that stops LLMs from oversharing sensitive data.
- Need-to-know access policies applied at AI request time
- Works across Microsoft Copilot, Glean, Gemini, and other enterprise AI assistants
- Audit logs for AI-system data access
Addresses a specific, underserved risk, LLM oversharing, rather than general AI security
Enterprise-only pricing (reportedly around $50,000/year) puts it out of reach for smaller organizations
Zenity
4.2Not listed
vs PVML+0.2
Security and governance for AI agents, from build time through to runtime.
- Security and governance across the agent lifecycle
- Runtime controls rather than pre-deployment review only

Runtime governance matches how autonomous agents actually fail
Only relevant once agents hold real permissions
ModelOp
4.1Not listed
vs PVML+0.1
Governance platform for tracking, controlling and reporting on enterprise AI models.
- Inventory of models in production
- Ownership and accountability tracking
- Performance and drift monitoring
Attacks inventory, which is the prerequisite for any control
