Best EU AI Act Compliance Tools in 2026
Short answer: Modulos if the AI Act is the whole job, since it is ISO 42001-certified and built around the Act's risk tiers, though it publishes no list price. Saidot and Credo AI cover the same governance record from an EU-native and a US vendor, also quote-only. IBM watsonx.governance is the one platform here with a published number, Risk & Compliance Basic from $3,500/mo. Vanta and OneTrust fit teams that want the Act folded into a compliance stack they already run.
Ten platforms mapped to the Act's risk tiers, deadlines, and fines, from a dedicated EU governance layer to enterprise GRC suites.
The EU AI Act does not ask for a security dashboard. It asks for a risk classification per AI system, a technical file, a conformity assessment for anything rated high-risk, and a paper trail a regulator can audit. Prohibited-practice rules and AI literacy duties have applied since February 2, 2025. General-purpose AI model obligations and the governance chapter followed on August 2, 2025. The Act's main enforcement machinery started August 2, 2026, and high-risk systems in the most sensitive domains, biometrics, critical infrastructure, employment, migration, get until December 2, 2027. Modulos is the platform built for exactly this brief: an ISO 42001-certified governance layer with the Act's risk tiers as the org chart, though it publishes no list price.
Toolradar data: of the 165 compliance management tools in the catalog, 15% offer a free or freemium plan, while 133 (81%) are paid-only.
That paid-only skew matches what the ten platforms below actually charge. Nine of them are quote-only, and the one exception, IBM watsonx.governance, still needs a sales call for anything past the entry tier. A generic GRC tool that has never named a risk tier belongs in compliance management instead. A shortlist built for security teams chasing prompt injection and model attacks is AI TRiSM tools. A shortlist of compliance software that uses AI to speed up audits, rather than software built for the Act itself, is AI compliance tools.
Start with Modulos or Saidot when the Act is the whole governance program and a smaller, EU-native vendor is the right size. Move to Credo AI or Holistic AI once the estate is big enough to need an enterprise registry and live intervention. Use IBM watsonx.governance when procurement wants a number before the demo. Use Vanta or OneTrust when the Act needs to sit next to SOC 2, ISO 27001, or a privacy program you already run.
How we ranked: these ten were chosen from the 165 compliance management tools in the catalog because each one maps at least one part of its product to the EU AI Act by name, not only to AI risk in general. Prices and features were checked on vendor sites in September 2026. No paid placement.

Teams that want the Act as the org chart, not an add-on module
Best for large organizations with complex compliance needs and dedicated budgets.
Watch out
Potential implementation and onboarding fees
EU-based teams that want an EU-native vendor and a shared risk library
Saidot's pricing is entirely custom and undisclosed, which is typical for enterprise AI governance platforms but opaque for smaller buyers.
Enterprises that need a system of record auditors and boards can read
Teams that want inventory, testing, and live intervention in one contract
Procurement teams that need a number before a technical evaluation
The pricing is fair for enterprise AI governance, with the $3,500/month Basic tier being competitive for compliance-focused teams, while the $6,450/month Advanced tier is expensive but justified for large-scale deployments.
Watch out
Advanced tier add-on up to 200 users
Teams already using Vanta for SOC 2 or ISO 42001
While it offers comprehensive features, these price points might be expensive for smaller startups, but fair for established companies prioritizing robust compliance automation.
Watch out
Potential for overage fees on usage
Enterprises that already run OneTrust for privacy or third-party risk
OneTrust's pricing structure is opaque, with only a free tier publicly listed.
Teams that want AI governance tied to an existing data-security program
Insurance, banking, and healthcare teams with an existing model-risk practice
Teams whose gap is proving lawful data use under a governance tool they already have
Watch out
Potential for high annual contract minimums.

What an EU AI Act compliance tool is
An EU AI Act compliance tool is software that inventories your AI systems, classifies each one by the Act's risk tier, generates the technical documentation and conformity evidence a notified body or regulator can review, and tracks the deadlines that apply to that tier.
That is four separate jobs, and not every vendor below does all four. The registry job is discovery, finding every model, agent, and vendor AI system in use, including the ones nobody logged (Credo AI, Holistic AI, Securiti, and OneTrust all lead with this). The classification job maps a system to prohibited, high-risk, limited-risk, or minimal-risk, the tier that decides which of the other jobs apply. The documentation job produces the technical file, the conformity assessment record, and the post-market monitoring plan a high-risk system needs before it ships. The data governance job, which Transcend specializes in, is proving the training and input data behind a system was collected and used on a lawful basis, a duty Article 10 puts on providers of high-risk systems directly.
Why the fine print matters more than the software category
The EU AI Act does not fine you for missing a product review. Article 99 sets fines up to €35 million or 7% of global annual turnover for a prohibited practice, up to €15 million or 3% for high-risk and general-purpose AI model violations, and up to €7.5 million or 1% for giving a regulator false or incomplete information, whichever figure in each tier is higher. Small and medium enterprises get the lower of the two numbers in each tier, not a separate cap.
Those figures explain why every vendor on this page leads with documentation and evidence, not with a dashboard. A tool that only flags a risky prompt does not produce the technical file Article 11 requires or the conformity assessment Article 43 requires for high-risk systems. Monitaur states the top fine tier on its own site, because its buyers, insurers and banks, already run model-risk files that predate the Act and know what a real exam looks like. The deadline that catches most buyers off guard is not the newest one: prohibited-practice and AI literacy duties have been live since February 2, 2025, and the general-purpose AI model chapter since August 2, 2025, so a system built and shipped this year can already be in scope.
Key Features to Look For
A risk-tier classification you can defend (Essential)
Vanta's EU AI Act product runs role and risk classification against the Act's own tiers and reuses evidence across ISO 42001 (about 50% control overlap) and NIST AI RMF (about 20% overlap). OneTrust and Credo AI ship the same EU AI Act, NIST AI RMF, and ISO 42001 templates. A tool that classifies against a generic risk scale, not the Act's tiers by name, will not hold up in an audit.
Discovery that finds the AI nobody logged (Essential)
Holistic AI discovers models, agents, LLM apps, APIs, and pipelines across AWS, Azure, GitHub, and Databricks, with 20+ integrations. Securiti and Credo AI run the same shadow-AI discovery, because a system you never inventoried cannot be classified, and an unclassified high-risk system is the Article 99 exposure nobody budgeted for.
A named framework, not a generic checklist (Essential)
Modulos maps one control library to the EU AI Act, ISO/IEC 42001, NIST AI RMF, and the EU Code of Practice for general-purpose AI. Saidot's library covers 260+ risks, 620+ controls, and 110+ policies, built EU-first. A platform that cannot name the article it satisfies is selling reassurance, not evidence.
Conformity assessment and technical documentation (Essential)
Saidot routes a system to internal review or an external conformity assessment inside the same workflow that documented the classification. Credo AI generates audit-ready evidence directly from the registry. This is the paperwork Article 43 requires before a high-risk system reaches the market, and it is the piece a spreadsheet cannot automate.
A published price, when one exists (Important)
IBM watsonx.governance is the only platform in this guide with dollar figures on its own pricing page, a monthly rate for its Risk & Compliance tiers and a metered per-unit rate for Model Management. Everywhere else, budgeting means a sales call before a technical evaluation, which stretches the runway toward the August 2026 and December 2027 deadlines.
Live intervention, not only a record (Important)
Holistic AI's Guardian Agents can observe, score, and then block, redirect, or escalate a live model call, mapped to the EU AI Act and ISO 42001. Most of the other platforms here stop at the paper trail and leave runtime enforcement to a separate product.
Model-risk depth for regulated industries (Important)
Monitaur's Common Controls library, 33 controls built for insurers and banks, names the EU AI Act's fine tiers directly and reuses the same evidence across state-level rules like Colorado's and New York's AI regulations. A general-purpose governance tool without that industry mapping means rebuilding the file examiners already expect.
A data-governance layer underneath the file (Nice to have)
Transcend enforces consent and data permissioning at the column level and answers whether a model may use a given piece of data, the Article 10 data-governance duty for high-risk systems. It is not a registry or a classification tool, so pair it with one rather than expecting it to replace one.
What to settle before the demo
Write down your risk tier in one sentence before the call: prohibited, high-risk, limited-risk (a chatbot that must disclose it is a machine), or minimal. The tier decides which of documentation, conformity assessment, and post-market monitoring you actually need.
Ask whether the registry finds shadow AI on its own or only tracks what you type in. Holistic AI, Credo AI, and Securiti lead with automated discovery across cloud and SaaS; a manual spreadsheet import is a weaker, different product.
Get the quote itemized by module. Modulos, Saidot, Credo AI, Holistic AI, OneTrust, Securiti, Monitaur, Vanta, and Transcend all publish no list price, so the sales call is where you learn whether the classification engine, the conformity workflow, and the monitoring dashboard are one price or three.
If IBM watsonx.governance is on the shortlist for its published entry price, confirm what one concurrent user and one module actually cover before assuming the price scales to a full team.
Decide whether you need a system of record, a runtime blocker, or both. Holistic AI's Guardian Agents intervene live; most of the platforms here stop at documentation.
Evaluation Checklist
On Modulos, ask for the ISO 42001 certification audit report and one worked example of an EU AI Act risk classification end to end.
On Saidot, run one system through the knowledge graph and confirm governance applied to a shared model or dataset actually inherits to every linked system, the feature the graph architecture is supposed to deliver.
On Credo AI, open the EU AI Act policy pack specifically and confirm it produces a conformity assessment document, not only a risk score.
On Holistic AI, run a Guardian Agent through one block-or-escalate scenario on your own agent framework, not the vendor's demo environment.
On IBM watsonx.governance, get the per-module, per-user cost past the published entry floor in writing before assuming it stops there.
On Vanta, confirm the EU AI Act impact assessment templates map to your actual risk tier, and ask which of the 150+ controls and 16 policies you would use versus inherit from ISO 42001 evidence you already have.
On Monitaur, ask for the mapping between its 33 Common Controls and the specific EU AI Act articles your risk tier triggers, not just the fine figures on the marketing page.

Prices checked on vendor pricing pages, September 24, 2026. IBM's AWS Marketplace bundle (1 basic instance, 5 AI use cases, 12,000 evaluations, 25 concurrent users) is a defined 12-month package, not a per-unit placeholder. Modulos, Saidot, Credo AI, Holistic AI, Vanta, OneTrust, Securiti, Monitaur, and Transcend publish no list price.
Mistakes to Avoid
- ×
Treating AI governance as one product. Registry, classification, conformity documentation, and runtime enforcement are different jobs. Holistic AI's Guardian Agents intervene live; most of the other nine stop at the paper trail.
- ×
Assuming IBM's published Basic tier is the team price. It buys one basic instance, one module, and one concurrent user; a compliance team of five is a different, unpublished number.
- ×
Skipping the deadline math. Prohibited-practice and AI literacy duties have applied since February 2, 2025, and general-purpose AI model rules since August 2, 2025. A system shipped this year can already be out of compliance before the 2027 high-risk deadline most buyers are planning around.
- ×
Reading Monitaur's fine figure as your own exposure. €15 million or 3% of turnover is Article 99's tier for high-risk and GPAI violations; the prohibited-practice tier is €35 million or 7%, and it is the higher of the euro figure or the percentage that applies.
- ×
Buying Transcend as a standalone EU AI Act tool. It proves lawful data use, which Article 10 requires for high-risk systems, but it does not classify a system's risk tier or generate a conformity assessment on its own.
- ×
Letting one quote-only vendor's stack decide the shortlist. Nine of the ten platforms here publish no list price, so the actual budget conversation happens in the demo, not on the pricing page.
Expert Tips
- →
Name your risk tier in the first email to a vendor. 'High-risk system, need Article 43 conformity assessment support' gets a sharper answer than 'we need AI governance.' Teams closer to a generic registry can start from Credo AI alternatives.
- →
Ask for IBM's per-user cost past the Basic floor in writing. The AWS Marketplace bundle (25 concurrent users, 12,000 evaluations) is a different contract from the direct IBM Cloud tiers, so do not average the two.
- →
- →
If you already hold ISO 42001, ask every vendor how much of that evidence carries over. Vanta cites roughly 50% control overlap between ISO 42001 and the EU AI Act; a vendor that cannot answer this question is starting your file from zero.
- →
For a bank or insurer, start the shortlist at Monitaur even though it is a quote. A 33-control library built for examiners is closer to what your regulator already expects than a general-purpose registry built for tech companies.
- →
Do not compare IBM's published line item with nine quote-only enterprise contracts on a spreadsheet. A published entry tier and a custom annual quote answer different budget questions. The broader category index is compliance management.
Red Flags to Watch For
- !
A vendor that prices the platform without naming which of registry, classification, conformity assessment, or monitoring is included.
- !
A classification feature that scores AI risk generically instead of assigning the Act's own tiers (prohibited, high-risk, limited-risk, minimal-risk) by name.
- !
A sales deck that quotes Article 99's fines to create urgency but cannot show a worked example of the conformity assessment document your risk tier requires.
- !
Treating Transcend's data-permissioning layer, or any single vendor's discovery module, as a complete EU AI Act program on its own.
- !
A compliant claim with no reference to which deadline, February 2025, August 2025, August 2026, or December 2027, the vendor is actually addressing.
The Bottom Line
Modulos or Saidot when the EU AI Act is the entire governance program and you want a vendor built around the Act specifically, from a smaller, EU-native or EU-focused company. Both publish no list price.
Credo AI or Holistic AI once the estate is large enough to need an enterprise registry, wide integrations, and, for Holistic AI, live Guardian Agents that can block or redirect a bad call. Skip both if you need a number before the first call, since neither publishes one.
IBM watsonx.governance is the only platform here with a published price on its own pricing page. Start there if procurement needs a budget line before a technical evaluation, and confirm the per-user cost past its single-seat entry tier.
Vanta or OneTrust when the Act needs to sit inside a compliance or privacy stack you already run, reusing ISO 42001 or SOC 2 evidence instead of starting over. Securiti fits the same logic from a data-security starting point instead of a GRC starting point.
Monitaur when the reader of the file is an insurance or banking examiner, not a generic auditor; it is the only vendor here that states the Act's fine tiers outright. Transcend when the actual gap is proving lawful data use under Article 10, paired with, not instead of, a registry from this list.

Frequently Asked Questions
What is the best EU AI Act compliance tool in 2026?
Modulos and Saidot, if you want a vendor built around the Act specifically: Modulos is ISO 42001-certified and Saidot is EU-native, and both publish no list price. Credo AI and Holistic AI are the enterprise-registry picks, also quote-only. IBM watsonx.governance is the only platform here with a published price on its own pricing page, if procurement needs a budget line before a technical evaluation. Vanta and OneTrust fit teams folding the Act into a compliance or privacy stack they already run.
How much does EU AI Act compliance software cost in 2026?
As of September 24, 2026, IBM watsonx.governance is the one vendor on this list with a published number: Risk & Compliance Basic from $3,500/mo, Advanced from $6,450/mo, Model Management from $0.64 per resource unit on IBM Cloud, and an AWS Marketplace bundle from $42,000 for 12 months. Modulos, Saidot, Credo AI, Holistic AI, Vanta, OneTrust, Securiti, Monitaur, and Transcend publish no list price; all nine require a sales quote.
Is there a free EU AI Act compliance tool?
Not among these ten as a production plan. IBM watsonx.governance lists a 14-day free trial on a shared environment. The other nine, Modulos, Saidot, Credo AI, Holistic AI, Vanta, OneTrust, Securiti, Monitaur, and Transcend, do not publish a free tier; each requires a sales conversation before you see a price, let alone a free plan.
What is the EU AI Act and who does it apply to?
The EU AI Act is a risk-based regulation covering AI systems placed on the EU market or used within it, regardless of where the provider is based. It sorts systems into prohibited, high-risk, limited-risk, and minimal-risk tiers, with obligations proportional to the tier. Prohibited-practice and AI literacy rules applied from February 2, 2025, governance and general-purpose AI model rules from August 2, 2025, the Act's main enforcement date was August 2, 2026, and high-risk systems in sensitive domains like biometrics and employment get until December 2, 2027. Article 99 sets fines up to €35 million or 7% of global turnover for prohibited practices, and up to €15 million or 3% for other high-risk and general-purpose AI model violations.
How does Credo AI compare with Holistic AI for EU AI Act compliance?
Both publish no list price and both lead with the governance registry. Credo AI's concrete offer is policy packs covering the EU AI Act, NIST AI RMF, and ISO 42001, plus 30+ ecosystem integrations and auto-discovery of shadow AI. Holistic AI adds a library of 40+ tests for bias, hallucination, privacy, and robustness, and Guardian Agents that can block or redirect a live model call, not only alert on it. Credo AI points continuous monitoring at tools you already run; Holistic AI sells the intervention itself.
Is IBM watsonx.governance's published price the real cost for a compliance team?
Only as a floor. That published Basic tier buys one basic instance, one module, and one concurrent user, and Advanced moves that to $6,450/mo. A team of five compliance staff working across several AI systems needs a quote past that entry number. Software pricing beyond the listed tiers is based on virtual processor cores, a metric IBM prices only through a sales conversation.
Which of these tools fits a bank or insurer?
Monitaur, if the file has to speak the language a model-risk examiner already uses. Its Common Controls library has 33 controls, it names NAIC's AI model bulletin and state rules from Colorado and New York alongside the EU AI Act, and it states the Act's fine tiers on its own site. Securiti and OneTrust also serve regulated buyers through their broader data-security and GRC platforms, but neither is built insurance-and-banking-first the way Monitaur is.
Can a data-privacy tool replace an EU AI Act registry?
No. Transcend's policy engine and consent management prove a model used data on a lawful basis, the Article 10 data-governance duty for high-risk systems, but its own site does not describe risk-tier classification or conformity-assessment documentation. Pair it with a registry and classification platform like Modulos, Saidot, Credo AI, or Holistic AI rather than expecting one product to do both jobs.
