Vanta vs Drata vs Complair: Which Compliance Tool for EU AI Act in 2026?

TL;DR — Vanta and Drata are world-class for SOC 2 and ISO 27001. They are not built for the EU AI Act and they don't try to be. If your buyers are EU enterprise asking AI Act questions, you'll be paying €40k/year for a tool that doesn't answer the questions you actually get asked. This article compares the three honestly, names where each one wins, and tells you which to pick by use case. Bias disclosure: I run Complair. I'll be specific about where Vanta and Drata beat us.

In 2024, "compliance software" meant SOC 2. By 2026, it means SOC 2 and ISO 27001 and the EU AI Act and the European Accessibility Act and the buyer questionnaire grind. The market hasn't caught up. Vanta and Drata still optimise for the US SOC 2 market. The EU AI Act layer is bolted on — not designed in.

I'll cover three tools:

• Vanta — the category creator. Founded 2018. €70M ARR by 2025. Tens of thousands of customers.
• Drata — the fast follower. Founded 2020. €40M ARR. Slightly later, slightly more enterprise.
• Complair — what I'm building. EU-native, AI-Act-first, buyer-questionnaire-pivoted. Early stage.

Honest disclosure up front: I run Complair. I'm not going to pretend I'm neutral. I will be specific about where Vanta and Drata beat us, where we beat them, and which one you should pick depending on what you actually need.

Where Vanta wins

SOC 2 + ISO 27001 motion for US-headquartered SaaS. This is what Vanta was built for, what Vanta is best at, and where Vanta's audit firm partnerships make a real difference.

If you are: - Selling primarily to US enterprise - Going through your first SOC 2 Type II - Bootstrapping or seed-stage and need to be audit-ready in 90 days - US-incorporated, US-data-residency

Pick Vanta. The integration coverage is unmatched. The auditor handoff is friction-free. The product is mature.

The downside: Vanta's AI Act coverage is a thin overlay on its SOC 2 framework. It doesn't classify your AI systems against Annex III, doesn't generate Article 13 transparency notices, and doesn't give you a buyer questionnaire library. You'll end up running Vanta plus another tool plus a spreadsheet for AI Act work.

Where Drata wins

Mid-to-upper-market SOC 2 with stronger audit-firm relationships and more enterprise polish. Drata has invested heavily in the auditor experience — many Big 4 audit teams prefer Drata's evidence packaging.

If you are: - Series B+ and going through SOC 2 with a Big 4 firm - Coming from a manual GRC stack and need migration help - Selling regulated US verticals (healthcare, financial services) with mature security teams as buyers

Pick Drata. The product is comparable to Vanta in features. The audit firm relationships and the white-glove service are where it earns its premium.

Same downside as Vanta on EU AI Act and buyer questionnaires.

Where Complair wins

This is where I have to be specific to be useful. We win on three things:

1. EU AI Act is native, not bolted on

Complair is built around the AI Act risk classification first. The data model maps 1:1 to:

• Article 6 risk tiers (unacceptable / high / limited / minimal)
• Annex III high-risk categories
• Article 13 transparency obligations
• Article 9 data governance requirements
• Article 14 human oversight specifications

When you onboard, the first thing the product does is inventory your AI systems and classify each against Annex III. The output is a written classification you can hand to legal, file in your AI register, and reuse in audits.

Vanta and Drata can capture some of this but their data models weren't designed for it. They treat AI Act as a checklist overlay on top of their existing controls framework.

2. Buyer questionnaire library that's actually a library

The CAIQ-Lite, SIG, AI-specific buyer questionnaires sit at the centre of the product. You answer once; the canonical answer is reused across all questionnaires. New questionnaires get auto-suggested answers from your library. Each answer is owned, versioned, and mapped to frameworks.

Vanta has a "Trust Center" — a public page that publishes some of your security posture. It's not the same thing. Drata has a similar add-on. Neither replaces the questionnaire workflow because they're built for buyers to visit, not for you to answer 73 questions on a tight deadline.

3. EU-native

• Frankfurt + Dublin AWS regions by default. No US data residency.
• GDPR Article 28 DPA template based on EU SCCs out of the box.
• German, French, Spanish, Italian — full localisation, not Google-translated UI.
• Pricing in EUR. Invoicing per EU VAT rules.
• Sub-processors: ~80% EU-based by design.

For an EU SaaS selling to EU buyers, this matters. EU buyers ask "where's the data?" before they ask anything else. With Vanta or Drata you're explaining a multi-region setup with US data residency on the primary tenant. With Complair you say "Frankfurt by default" and move on.

Where Vanta and Drata still beat Complair

I have to be honest: we lose on three big dimensions today.

1. SOC 2 / ISO 27001 maturity

We're working towards both. Today, if SOC 2 is your top priority, do not buy Complair as your primary. We will be there by Q1 2027 but we're not there yet. Vanta or Drata is your pick.

2. Integration breadth

Vanta has ~300 integrations. We have ~30, focused on the EU stack (Personio, Pennylane, Lexware, plus the standard set of Slack, GitHub, AWS, GCP, Linear). If your evidence-collection scope is wide, Vanta wins.

3. Audit firm relationships

Vanta has 30+ deep audit firm partnerships. Big 4 auditors know the Vanta packaging cold. Complair is new. If your audit firm has never heard of us, the conversation is longer.

Decision matrix — which one to pick

If your situation is…	Pick
US SaaS, primary need is SOC 2, selling to US enterprise	Vanta
Series B+, primary need is SOC 2 + ISO 27001 with Big 4 auditor	Drata
EU SaaS, primary need is AI Act + buyer questionnaires	Complair
EU SaaS, primary need is SOC 2 (US enterprise expansion)	Vanta + Complair stack (pay for both — Vanta for SOC 2, Complair for AI Act + questionnaires)
Selling AI products to enterprise, AI Act questions in every deal	Complair
Pre-seed / seed, no money, need to start somewhere	Complair free tier (it's actually free)
Healthcare or financial services, regulated US verticals	Drata
Want monday.com-style workspace UX, not enterprise-dashboard UX	Complair

Pricing — what each tool actually costs

Numbers below are EUR-equivalent annual contract. All three discount aggressively for annual prepay; don't pay sticker.

Vanta: ~€8k/year entry tier, ~€20k/year typical, ~€40k+/year for full SOC 2 + ISO + GDPR scope at ~50-person company.

Drata: ~€7.5k/year entry, ~€18k/year typical, ~€35k+/year for full scope. Slight discount on Vanta historically.

Complair: Free tier (5 AI systems, 1 questionnaire). Growth €99/month (€1,188/year). Scale €399/month (€4,788/year). Enterprise quoted; typical €15k–€25k/year for 100-person SaaS.

The price gap reflects scope. Vanta and Drata cover more total surface area (SOC 2 + ISO 27001 + GDPR + vendor management + everything-as-evidence). Complair covers EU AI Act + buyer questionnaires + GDPR ROPA deeply, less elsewhere. Apples to apples on AI Act + questionnaires alone, Complair is 4–6× cheaper.

Migration path — moving from Vanta or Drata to Complair

If you're already on Vanta or Drata and considering switching:

1. Don't switch unless you have to. SOC 2 in flight = stay until the audit closes.
2. Run dual for the AI Act layer specifically. Keep Vanta for SOC 2; add Complair for AI Act + questionnaires for 6–12 months. Re-evaluate at renewal.
3. Export your data first. Both Vanta and Drata support data export. Document your control framework, evidence library, vendor list, and ROPA before you cancel.
4. Map controls. ~70% of SOC 2 controls map cleanly to AI Act risk-management controls. The remaining 30% need rework.
5. Onboarding takes 2–4 weeks. Plan migration during a slow sales month.

What about open-source / DIY alternatives?

Briefly:

• Trustpage — security questionnaire automation. Narrower scope; complementary to Vanta/Drata.
• Secureframe — third option in the SOC 2 space. Comparable to Drata.
• Sprinto — Indian SOC 2 player; aggressive pricing. Limited EU AI Act coverage.
• DIY — Notion + spreadsheet + manual evidence collection. Works at <10 employees. Breaks past 30.

None of the above beat the dedicated tools on time-to-value once you cross 20 employees.

What to do this week

If you're shopping for a compliance tool in 2026:

1. Make a list of the 3 questions your top 5 buyers actually ask. If 4+ of those 5 ask AI Act questions, that's your priority.
2. Try Complair free (sign up) — it costs nothing, takes 1 hour, and tells you whether the AI-Act-first model is what you need.
3. Get a Vanta or Drata demo — for SOC 2 specifically. Both will give you 30 minutes for free.
4. Decide based on buyer questions, not vendor pitches. The right tool is the one that answers the questions your buyers ask, not the one with the slickest dashboard.

FAQ

Q: Can I run Vanta and Complair together? Yes. Many EU SaaS teams will. Vanta for SOC 2 + ISO 27001, Complair for AI Act + buyer questionnaires + EAA. Cleanest split.

Q: Does Complair generate SOC 2 evidence? Not yet. Q1 2027 target. Today we generate AI Act technical documentation, ROPA, DPA addendums, transparency notices — not SOC 2 evidence.

Q: Do you integrate with Vanta? On the roadmap (Q4 2026). Plan: bidirectional sync of vendor risk records and policies, so Vanta's audit framework can pull from Complair's AI register without duplication.

Q: How long does Complair onboarding take? Free tier: 1 hour. Scale tier with 90-min kickoff call: typically AI register populated, first 3 documents generated, first questionnaire answered in week 1.

Q: Is Complair safe to use during a Vanta-led SOC 2 audit? Yes. We're a separate system of record for AI Act. Audit-evidence overlap is minimal. Talk to your auditor; in our experience they welcome more documentation.

Q: What happens if Complair gets acquired? We're early stage. If we get acquired, our DPA includes a clause guaranteeing 12-month service continuity at locked-in pricing for any contract dated before the acquisition. Standard EU buyer protection.
