Octelium is a free, open-source, self-hosted secure access platform for people, workloads, and AI agents reaching hybrid infrastructure, SaaS, and applications. It places protected resources behind identity-aware proxies and applies authorization policies at the application layer. Listed protocols and services include HTTP, gRPC, web applications, SSH, Kubernetes, PostgreSQL, MySQL, RDP, DNS, SOCKS5, TCP, UDP, MCP, and LLM modes. Cluster Secrets can hold upstream credentials and inject them after authorization, avoiding credential storage by users or workloads. Identity integrations include OIDC and SAML 2.0 providers such as Okta, Microsoft Entra ID, Google Workspace, Keycloak, and Auth0, plus GitHub OAuth2. Native authentication includes FIDO2 and WebAuthn passkeys, TPM 2.0, and TOTP. MCP and LLM gateways govern tool calls, arguments, models, tokens, and usage records. OpenTelemetry-based logs and metrics cover layer-7 activity. Octelium runs on Kubernetes; an installer provisions a single-node Cluster on a fresh Linux server, while larger deployments use managed or on-premises multi-node Kubernetes.
