Our verdict on Sanctum Runtime
Sanctum Runtime sits between AI reasoning and execution to govern actions before they create side effects. It combines runtime verification, policy enforcement, audit logging, and operator decisions such as approve, block, or hold. The product is aimed at teams managing connected AI agents and automated systems, especially where action visibility and controlled execution matter more than a general-purpose AI development environment.
Its plan structure follows a progression from observation to enforcement and organizational administration. Developer includes observe-only agent monitoring, an observe-mode Connect proxy, Live Feed and audit read access, and three SDK runtimes. Personal adds gating, basic policies and alerts, presets, and an optional weekly digest. Operator adds full Shield enforcement, holds, mobile approval and denial, webhooks, a hosted Connect proxy, and encrypted platform keys. Team adds SSO, RBAC, compliance evidence export, organization-wide policy ownership, and a priority support path. Enterprise extends this with private cloud or air-gapped deployment, custom SSO and RBAC, custom audit retention, SLA, and dedicated support.
Sanctum Runtime fits hybrid environments: teams can use web, API, iOS, and Android access alongside a self-hosted runtime deployment. Its open-core self-hosted model and hosted Connect proxy give organizations different deployment paths, while webhooks provide an integration route for connected workflows. The strongest fit is a team that needs runtime action governance, mobile operator decisions, and an audit trail across AI systems. Organizations seeking these controls with enterprise deployment options should consider it; teams looking primarily for a broader set of model-content or output-focused security functions may prefer a product with a different security scope.
