Vanta alternatives: 8 tools compared (October 2026)

Diligent is a governance, risk and compliance platform used by boards, legal, compliance and internal audit teams. Its audit management software uses AI agents to set up audits, test controls, monitor risk, manage evidence requests and draft reports for boards and audit committees.

Key functions

• Audit Agent rolls forward prior audits, builds project structures, executes control tests and drafts documentation
• AI Orchestrator turns plain-English prompts into work by specialized agents, with an audit trail
• Risk Agent provides continuous control monitoring and risk assessments

Compared with Vanta

• Can store data in the EU; Vanta states no EU option.
• Strong in the same markets as Vanta: United States.

Check before buying: Diligent sells a broad GRC suite, so define whether you need only audit management or also board, risk and compliance modules, since pricing is by quote. Customers choose a hosting region, including Frankfurt and London, and the trust page lists ISO/IEC 27001 and SOC 2 Type II. The DPA with EU standard contractual clauses and the subprocessor list are public. Clarify how agent actions and AI drafts are logged so audit work stays reviewable.

Drata is a compliance automation and GRC platform that collects evidence, monitors controls and uses AI agents for security questionnaires, vendor risk and the governance of AI agents.

Key functions

• AI Questionnaire Assistance drafts answers to security questionnaires
• AI agents assess vendors, collect evidence and follow up
• Agent Governance discovers AI agents in your environment and enforces policies

Compared with Vanta

• Strong in the same markets as Vanta: United States.

Check before buying: Drata does not publish prices or customer data regions, so ask for both before a trial. Integrations need read access to cloud, identity and HR systems, so review the permissions. If you use Agent Governance, define who approves agent policies.

OneTrust is a governance platform for privacy, consent, data use, technology risk, third parties and AI, aimed at large organizations that need one system for these programs.

Key functions

• Discovers AI systems, agents, models and datasets and keeps them in one inventory
• Automates risk tiering aligned to the EU AI Act, NIST and ISO 42001
• AI Guard SDK detects sensitive data in prompts and responses before the model sees it

Compared with Vanta

• Built for larger organizations than Vanta's smallest customers.
• Strong in the same markets as Vanta: United States.

Check before buying: OneTrust does not publish prices, and licensing depends on the modules chosen, so scope the modules first. Check whether runtime controls cover your AI platforms, since the page names Amazon Bedrock and Microsoft Foundry. Ask for data hosting regions and certifications, which the pages we checked did not state.

trail is a Munich-based platform for AI governance and GRC automation that registers and classifies AI systems, generates documentation and runs agents for recurring compliance tasks.

Key functions

• AI registry with classification under the EU AI Act and ISO/IEC 42001
• Automated documentation generation for AI systems
• GRC agents handle recurring governance tasks in existing tools with human approval

Compared with Vanta

• Can store data in the EU; Vanta states no EU option.
• Headquartered in Germany, Vanta in United States.
• Built for larger organizations than Vanta's smallest customers.

Check before buying: trail does not publish prices, so ask for the model by number of AI systems or modules. Choose the deployment model early, since on-premises and own-cloud operation shift maintenance to your IT. Define who approves agent changes in connected tools.

Aveni builds AI tools for regulated financial advice in the UK. Aveni Assist handles admin around client meetings for advisers and planners, and Aveni Detect automates quality assurance and Consumer Duty monitoring for compliance teams.

Key functions

• Aveni Assist summarizes advice meetings and drafts suitability reports in Word templates
• Automatic CRM updates and drafts of client emails

• Headquartered in United Kingdom, Vanta in United States.
• Built for larger organizations than Vanta's smallest customers.
• Names fewer security certificates: 1, Vanta 3.

Check before buying: Aveni is designed for UK rules such as the FCA Consumer Duty, so firms elsewhere should check how far the checks match local requirements. The privacy notice says data may leave the UK or EEA with safeguards, and subprocessors are listed only on request. Recording advice meetings needs client consent, and drafted reports must be reviewed by the adviser.

Key functions

• AI drafts data protection impact assessments

Compared with Vanta

• Publishes a price (from €59 per month); Vanta quotes on request.
• Can store data in the EU; Vanta states no EU option.
• Headquartered in Germany, Vanta in United States.
• Different pricing model: flat fee instead of contact for pricing.

Check before buying: Check which modules you need, since privacy has public prices while information security and the EU AI Act are quoted separately. Bundling frameworks can reduce the price. Support scope and response times differ by plan, and there is no phone hotline; requests run through the customer platform.

• AI identifies and prioritizes security and compliance risks with remediation guidance
• Automated evidence collection and audit preparation

Compared with Vanta

• Headquartered in Germany, Vanta in United States.
• Strongest elsewhere: Germany.

Check before buying: All plans are priced by quote, so compare what expert support is included in Pro and Enterprise. The website does not name data hosting locations or certifications in plain text; check them in the trust center. Decide whether you need an external data protection officer, since that changes the plan.
