- 11 tools compared: Openlayer, Microsoft Purview, Credo AI, IBM watsonx.governance, OneTrust, Holistic AI, ValidMind, Collibra, Modulos, Securiti, Arthur
- Openlayer (best for: Policy enforced and evidenced across the AI lifecycle): Free Basic plan; Enterprise custom
- Microsoft Purview (best for: Copilot plus non-Microsoft AI in the same tenant): $15 per 1M non-Microsoft audit records; Copilot audit included
- Credo AI (best for: A registry across clouds, not one suite): Check current pricing; per AI use case, 12-month contract
- IBM watsonx.governance (best for: A module with a number on the page): $3,500/mo Basic, 1 concurrent user
Short answer: Openlayer when governance has to be enforced and evidenced on the AI systems actually running, not just documented. Microsoft Purview when the AI you must govern is Copilot plus a few SaaS bots, because the meters are public. Credo AI when you need a vendor-neutral registry and can wait for a quote. IBM watsonx.governance when finance wants a published module, from $3,500 a month.
A registry with an owner on every model is a different buy from a bias test or a SOC 2 binder. Dupple data: Toolradar, our software directory, tracks 155 compliance management tools as of September 2026. That directory is audit and GRC software, so this page ranks the governance layer and leaves certification automation to AI compliance tools, while model testing sits in AI risk management.
Every price below was checked on the vendor's own site, or on a marketplace listing that vendor sells, on September 23, 2026.
Quick comparison
| Tool | Best for | Starting price | Standout |

| Arthur | A small team that can pay by card | Free plan; Premium $60/mo | Enterprise is the governance and VPC tier |
What an AI governance tool actually does
An AI governance tool is software that keeps an inventory of models, agents, and AI vendors, ties each one to an owner and a policy, and stores the approval and evidence a regulator or a customer will ask for.
Purview fits a Copilot workplace and misses a model that lives elsewhere. Credo, Holistic AI, and Modulos are for an inventory you cannot yet list, and ValidMind bills each model, which a bank can forecast and a chatbot team will overpay.
How we chose
I ranked 11 products a company can use as the system of record for AI, not the SOC 2 tools inside Toolradar's compliance management category. Plan names and prices come from each vendor's site on September 23, 2026, and from AWS Marketplace where the vendor publishes a contract there. For a separate data-driven ranking, see Toolradar's AI governance guide.
Openlayer, the platform that enforces policy instead of filing it
Openlayer is an enterprise AI governance platform that connects policy to technical control across the whole AI lifecycle. It keeps one inventory of internally built and third-party AI systems, classifies and scores their risk, runs approval workflows, and maps controls directly to policies, SOPs, and regulatory requirements.
Who it's for: Enterprises that have to prove, not just claim, that every AI system is governed, especially when in-house models and vendor AI sit side by side.
The Basic plan is free for one member, five projects, and 20,000 inferences a month, with the AI test library, observability, and tracing. Enterprise is custom-quoted on scale, deployment, and support, and adds unlimited members, SAML SSO, role-based access, on-prem deployment, and compliance reports.
Where most governance tools document policies and controls, Openlayer verifies and enforces them against the systems actually running in development and production, with continuous testing and monitoring, runtime guardrails, and auditable evidence of what was tested, approved, monitored, and enforced. Pre-built mappings cover the EU AI Act, NIST AI RMF, ISO/IEC 42001, and OSFI E-23, with end-to-end traceability from a governance requirement down to system behavior.
The catch: Compliance reports and the deepest governance features sit in Enterprise, so the free plan is for testing the platform on real projects, not for running the governance program.
The pick when governance has to reach production: one system of record, controls enforced at runtime, and evidence generated as you go.
Microsoft Purview, the buy when Copilot is the estate
Microsoft Purview is the layer you already half-own if the company lives in Microsoft 365. Audit for Copilot, Security Copilot, Copilot Studio, and Azure AI Studio is included, and non-Microsoft AI is the part that starts a new meter.
Who it's for: A tenant where Copilot is the main assistant and a few outside chatbots need an audit trail.
On the Azure pricing page, non-Microsoft AI audit logs kept for 180 days are $15 per 1 million records, which a Copilot-only tenant can ignore. Data Lifecycle Management is $6 per million text messages a month, and each non-Microsoft 365 generative prompt and each response counts as its own message, so logging both sides doubles the count.
eDiscovery of that non-Microsoft AI data is $20 per GB a month, separate from the audit meter when legal holds the logs. Microsoft's Unified Catalog example prices 200 governed assets, including AI models linked to governance concepts, at $100 for 30 days. Assets that sit in the Data Map without that link are not billed.
The catch: That catalog example is not a license for the audit meter, so a budget that stops at the asset example still owes the log charge once non-Microsoft prompts are stored.
First system to turn on when Microsoft is the AI workplace, and the wrong only-system when the models live somewhere else.
Credo AI, the registry when the estate is not one cloud
Credo AI governs agents, applications, models, and vendors, with policy packs for the EU AI Act, NIST AI RMF, ISO 42001, and SOC 2. GAIA, its governance assistant, is generally available, and the demo does not ask for a card.
Who it's for: AI that spans Snowflake, Databricks, AWS, Azure, ServiceNow, GitHub, and MLflow, when you can wait through procurement. A team that needs a number this week should start with Purview or IBM.
Credo does not publish a list price, so there is no public number to compare. On AWS Marketplace, sold by the vendor, the Enterprise Plan is an annual subscription based on the number of AI use cases, on 12, 24, or 36 month contracts, and the dollar is a private offer, which is also what Microsoft Marketplace says.
The catch: The quote moves when someone registers another agent, so the quantity can rise after you sign. There is no public trial of the paid platform, which leaves the demo as the only look before that contract.
The default dedicated registry once the per-use-case price is written into the order form.
IBM watsonx.governance, the module with a printed monthly price
IBM watsonx.governance puts monthly dollars on the page for a committee that will not approve a quote-only vendor.
Who it's for: A regulated team that wants inventory, risk assessment, and evaluations on a named plan, and that can live with one concurrent user until an add-on is quoted. If five people need access on day one, the rollout waits on a seat quote.
The page lists a free trial instance for 14 days in a shared environment. Model Management starts at $0.64 on IBM Cloud, pay as you go, with a 30-day trial. IBM does not print a billing unit beside that figure, so confirm the unit before you forecast a month of it.
Risk and Compliance Basic starts at $3,500 a month on IBM Cloud for 1 instance, 1 module, and 1 concurrent user. Advanced starts at $6,450 a month as enterprise software on the same one-user shape. Licensing is by virtual processor core, with no core price printed, and add-ons cover more instances, modules, and users.
The catch: A second reviewer is an add-on the page does not price. A year of Basic, at the printed monthly rate, is $42,000 before those seats.
The governance buy when the budget must be a number this quarter.
OneTrust, when privacy already lives on this platform
OneTrust sells AI Governance beside consent, privacy, tech risk, and third parties.
Who it's for: A company that already pays OneTrust for privacy and wants models, agents, datasets, and vendors in that same record. Starting here with no OneTrust estate is heavier than Purview or Credo.
OneTrust publishes no dollar for AI Governance, and the meter is admin users and AI inventory. Overages move you to the next tier through an account executive, which means a larger inventory is a new negotiation. The package lists EU AI Act, NIST, and ISO 42001 assessments, approval gates before production, and runtime controls on prompts, outputs, and agent tools, including MCP.
The catch: Each solution package is its own meter. Adding AI Governance on top of privacy is a second contract line, not a checkbox on the price you already signed.
Right when OneTrust is already the privacy system, and an open-ended commitment when it is not.
Holistic AI, when the inventory is missing
Holistic AI discovers models, agents, and vendor tools across cloud, code, and SaaS, then tests them and holds a deployment gate. The site describes 40 or more tests, plus Sentinel agents that watch actions and Operative agents that block, redirect, or escalate, none of which fills in an owner.
Who it's for: A lead who cannot name what is running. If the inventory is already clean, choose Credo instead, because you would be paying for discovery you no longer need.
Holistic AI does not publish a plan price, so the path is a conversation rather than a card checkout, and any rollout date should wait on a written scope.
The catch: Discovery without a quoted scope still leaves the bill unknown, and the tests can overlap observability tools you already pay for.
The pick when shadow AI is the problem, and only after that scope is on paper.
ValidMind, when each model is a line on the contract
ValidMind is built for financial institutions that govern traditional models and generative systems in one workflow, with inventory, approvals, and performance tracking in the same modules.
Who it's for: A bank or insurer that can count models. A team with a few chatbots and no model-risk office will overbuy it.
The company site offers a custom plan and does not print a dollar. The AWS Marketplace listing, sold by ValidMind, prices a model at $5,000 for a year, with 24 and 36 month contracts, and states no refunds. A model is any statistical, AI, or generative system placed in inventory, and validation automation is a separate add-on.
The catch: Ten models on that unit are $50,000 a year before automation. Retiring a model is how the count drops, and a website quote can differ from the marketplace unit, so ask for both.
The clearest per-model price here for a regulated inventory, once you know which contract you are signing.
Collibra, when the data catalog should hold the agents too
Collibra AI Command Center is a control plane for use cases, models, and agents, tied to the data those systems consume.
The product page lists EU AI Act and NIST AI RMF templates, AI UC-1 assessments, and a Trust Score per system. A CLI registers use cases from code, with links to AWS, Azure, Google, Databricks, SAP, and MLflow.
Who it's for: A data office that already runs Collibra and now has agents in production.
Collibra does not publish a list price for AI Command Center. Do not assume the data-catalog contract already includes the AI registry.
The catch: Lineage across Azure AI Foundry and Databricks is why you stay, and a second registry would duplicate owners and evidence.
Extend the catalog you already run, rather than standing up a new one for a single new agent.
Modulos, when the work is evidence and a live control
Modulos links AI systems to controls, evidence, and risk. Scout discovers systems and shows an approval state, so the inventory and the sign-off are the same record.
The site says Modulos is ISO/IEC 42001 certified by CertX and SOC 2 Type II audited by Insight Assurance, with one control library for the EU AI Act and that same standard.
Who it's for: A lead who must show a control passed, not only that a policy PDF exists. Personal habits with chat tools are covered in using AI responsibly.
Modulos does not publish a plan price, and the site offers a call rather than a rate card.
The catch: The vendor's certifications are not yours, and you still have to produce the evidence an auditor asks for.
A fit when you must show a passed control and you already have the quote, and a mismatch when a policy file is enough.
Securiti, when the risk is the data inside the model
Securiti sells modules for discovery, sensitive-data intelligence, DSPM, privacy, consent, and a Secure and Govern AI use case that includes LLM firewalls. You buy modules for the use cases you need.
Who it's for: A data-security team asking which sensitive fields can reach a model. If you need a policy registry and not classification, choose Credo or OneTrust.
Securiti publishes no plan dollar, because pricing is personalized by module.
The catch: A firewall module and a governance module can both land on the quote. Buying only the firewall leaves owners and approvals undone.
Buy it when sensitive data reaching a model is the risk you are actually trying to reduce.
Arthur, the card price for a small team
Arthur is the only tool here with a self-serve monthly price. Free and Premium are monitoring plans, while Enterprise is where dedicated infrastructure, governance, and support sit.
Who it's for: A small team that needs written limits this week, and not a stand-in for Credo or IBM once legal wants a policy pack and an approval on every agent, and production model ops still belong with MLOps tools.
Free is $0 a month, for 4 use cases, 2 projects, 7-day retention, 5,000 jobs, 300,000 spans, 12,000 inferences, and 3,000 evals. The retention is too short to serve as an audit history.
Premium is $60 a month for 100 use cases, 10 projects, 30-day retention, 20,000 jobs, 1.2 million spans, 100,000 inferences, and 75,000 evals, and Enterprise is custom. Free alert checks are 6 an hour, with 3 custom alerts per model.
The catch: A year of Premium is $720, and that spend still buys the monitoring cap. Governance, as Arthur describes it, sits on the custom tier.
Use the free plan or Premium to watch a few use cases, then move the system of record when an auditor asks who approved the agent.
What you will actually pay beside the registry
A year of the printed IBM modules: the Basic total above is $42,000 for one concurrent user, and a year of Advanced is $77,400 on that same one-user card, and further seats have no printed price.
Purview, if you scale the catalog example: five times that example is $500 before discounts, and only for assets linked to governance concepts.
Runtime filters are a second invoice: Amazon Bedrock Guardrails charge content filters at $0.15 per 1,000 text units, and denied topics use that same rate. AWS's chatbot example, 1,000 queries an hour, is $0.90 an hour for those two filters together.
Sensitive information filters are $0.10 per that same text-unit size, and AWS's transcript example is $4 for 10,000 summaries. Automated Reasoning checks are $0.17 per text unit per policy at that size, $6.80 in AWS's clinical example. A text unit has a character cap, so 5,600 characters are 6 units, and gateways are a separate purchase covered in LLM gateways.
Dupple data: Toolradar tracks 41 AI observability tools as of September 2026, on the observability ranking. Fiddler lists a free guardrail tier and a Developer plan at $0.002 per trace, with Enterprise as the governance and VPC tier, so one million traces at that rate are $2,000.
Comparisons of that layer live in observability platforms and LLM observability, and prompt-injection products belong in AI threat detection.
How to choose for the estate you actually have
Match the registry to where the AI already sits, then add filters only for apps that face customers. AI agents that take actions need an owner and a gate.
Stay on Purview when Microsoft 365 is the workplace, and add Credo or Collibra when another cloud holds models those meters never see. Choose IBM when one concurrent user is an acceptable start, ValidMind when the regulator already thinks in model inventories, and Arthur's monitoring plans only while that choice is still open.
ServiceNow AI Control Tower is the same idea on the Now platform, sold as a private offer with no public list price, which fits a team already on that platform.
Common mistakes when pricing this stack
Treating the Purview catalog example as the whole AI bill ignores the audit meter and the message meter, which bill non-Microsoft prompts on their own.
Staffing IBM Basic as a team license spends that one-user annual total, then finds the next seat has no printed price.
Counting ValidMind automation inside the model fee still owes the add-on, and the website plan may not match the marketplace unit.
Calling Arthur Premium a governance platform pays for a year of monitoring and still needs the custom tier for the approval record.
Enabling two Bedrock filters and budgeting one of them stacks content filters with denied topics, then bills sensitive-information filters again.
Signing Credo without a use-case count locks an annual private offer, then every new agent changes the quantity.
Buying Securiti's firewall line and skipping the registry filters the prompts and still leaves the owners unassigned.
FAQ
What is the best AI governance tool in 2026?
Openlayer, when governance has to be enforced and evidenced on systems already running. Microsoft Purview is the pick if Copilot is the estate, because non-Microsoft audit is a published meter and Copilot audit is included. Credo AI is the better registry when models span several clouds and you can wait for a private per-use-case contract. IBM watsonx.governance is the better pick when you need the printed Basic module and can live with one concurrent user.
How much do AI governance tools cost in 2026?
On September 23, 2026 the published anchors are IBM Basic at $3,500 a month, Advanced at $6,450 a month, Model Management from $0.64, ValidMind at $5,000 per model for a year, Arthur Premium at $60 a month, and Purview at $15 per million audit records, $6 per million messages, and $20 per GB for eDiscovery. Credo, OneTrust, Holistic AI, Collibra, Modulos, and Securiti publish no list price.
Is there a free AI governance tool in 2026?
Arthur's free plan covers 4 use cases and 7 days of retention, enough for a pilot and short for an audit. IBM offers a 14-day shared trial and a Model Management trial, while Fiddler's free tier is guardrails rather than a registry. Credo, OneTrust, Holistic AI, Collibra, Modulos, Securiti, and ValidMind's website do not publish a free platform.
Should I buy Microsoft Purview or Credo AI?
Buy Purview for a Microsoft 365 workplace and public meters, including $100 for 200 governed assets in Microsoft's catalog example. Buy Credo when models sit in several clouds and an annual per-use-case contract is acceptable. Paying both to be the only system of record means two places to update the same owner.
Do Bedrock Guardrails replace a governance platform?
No. Content filters are $0.15 per 1,000 text units, denied topics use that rate, and neither stores an owner or an approval. AWS's chatbot example is $0.90 an hour for those two filters together. You still need Credo, Purview, Collibra, or IBM when someone asks who signed off.
What is the difference between AI governance and AI compliance?
AI compliance, in our compliance guide, is SOC 2, ISO 27001, and the evidence those audits demand. AI governance is the inventory and the approval of models and agents. Toolradar's 155 compliance tools are mostly the first job, and teams that need both usually buy one tool from each list.
How much is ValidMind for 10 models?
Ten models are $50,000 for a year on the AWS contract ValidMind sells, with no refunds, and validation automation is extra. The website also sells a custom plan, so confirm the order form uses that same unit.
Bottom line
Choose Openlayer if governance has to be enforced at runtime, turn on Purview if Copilot is the AI you have, get Credo's per-use-case price in writing before an annual contract, and use IBM Basic only if one concurrent user is enough. ValidMind's marketplace unit is the public per-model price for a bank inventory.
