Legalithm vs Vanta, EU AI Act vs broad GRC (2026)
Vanta is a mature, funded platform for broad security and GRC automation, SOC 2, ISO 27001, GDPR and more, across your whole company. Legalithm is narrower on purpose: the EU AI Act, the Cyber Resilience Act and the European Accessibility Act, delivered in your developer workflow and embeddable on your site. Most teams that compare us are not choosing between them. They are working out which problem they have first.
How they differ
| Legalithm | Vanta | |
|---|---|---|
| Focus | EU AI Act + web compliance (cookie & AI transparency) | Broad security & GRC automation (SOC 2, ISO 27001, GDPR) |
| Pricing | Free to start | Paid, sales-led |
| How you use it | Dev CLI + MCP, embeddable widgets, web app | Dashboard + integrations |
| EU AI Act depth | Core product, cited to EUR-Lex | One framework among many |
| Approach | Deterministic rules engine, no LLM | Automation platform |
| Origin | EU-built | US-based |
Where Legalithm goes deeper
- The corpus is the product. Every classification cites the article or annex it came from, so you can check the answer rather than trust it.
- It runs where the work happens. A CLI and an MCP server put classification in your editor and your CI, not only in a dashboard someone visits once a quarter.
- The visitor-facing surface is included. Cookie consent, AI disclosures and a public transparency page are embeddable, which is the part of AI Act compliance your users actually see.
- The output is durable. A determination is stored dated, cited and content-hashed, so a position taken in March is still verifiable in December.
- You can start without talking to anyone. The assessment is free and needs no account.
What Legalithm does not do
- No SOC 2 or ISO 27001 automation, no evidence collection for security certifications. If that is the job, Vanta does it and we do not.
- No vendor security reviews, access reviews or employee onboarding checks.
- Not legal advice. What you get is a documented, cited position to take to counsel, which is a different thing from counsel.
- Smaller and younger. Vanta has scale, funding and a support organisation that we do not.
When to choose which
When Vanta
Choose Vanta if your priority is broad security certification and multi-framework GRC automation across the company, and you have budget and a procurement process for it.
When Legalithm
Choose Legalithm if the EU AI Act is the specific thing you have to answer for, you want it in the developer workflow and on your site, and you want to see the answer before you pay.
