Open-source gateway (free)
The Vaikora reference gateway is MIT-licensed and self-hostable. Includes the deterministic policy engine, six content modules (PII, jailbreak, injection, semantic, domain risk, email classification), and the policy evaluation API. Run it in your own infrastructure, no vendor lock-in. The MCP server companion is also free and lives on PyPI.
Vaikora Control Plane (commercial)
The Vaikora Control Plane is hosted by Data443 and adds the SHA-256 cryptographic audit chain, pre-built compliance presets for SOC 2, HIPAA, GDPR, PCI DSS, and ISO 27001, the approvals queue with Slack OOB routing, multi-tenant administration, real-time dashboard, and a vendor SLA. Pricing is quote-based and scales by agent count and request volume.
AWS Marketplace and Azure Sentinel
Vaikora is available through AWS Marketplace as a SaaS subscription with private offers and EDP draw-down. Vaikora-AzureSecurityCenter ships as an Azure Sentinel solution. Both procurement paths apply existing cloud commitment dollars to Vaikora.
How to evaluate
Self-host the open-source gateway to validate the policy engine and the content modules against your workload. Book a demo when you need the audit chain, compliance presets, or vendor SLA. Most pilot conversations move to a paid Control Plane within 30 days.
