Not a Workflow SaaS

A BPMN Process Engine
You Actually Own

Sanctum Flow is not a workflow automation platform you rent. It is a complete BPMN 2.0 process execution engine — with a visual editor, a step-based state machine, SLA breach monitoring, and an immutable audit trail — deployed on your own infrastructure. The same engine that runs our delivery pipeline is available for yours.

01 — Design

Visual
Process Design

Model complex business processes with an intuitive BPMN visual editor. Drag tasks, gateways, and events onto a canvas — no coding required. Simulate execution paths before deployment to catch deadlocks early.

  • Full BPMN 2.0 specification with bpmn-js powered canvas, element palette, and properties panel.
  • Palette-driven design: drag tasks, sub-processes, exclusive/parallel gateways, and boundary events.
  • In-canvas simulation mode to trace execution paths, detect deadlocks, and validate logic before going live.
  • Versioned process definitions with diff comparison, rollback capability, and draft-to-published lifecycle.
01

Model

Drag tasks and gateways onto the bpmn-js canvas.

02

Configure

Set step properties, SLA thresholds, and event triggers.

03

Publish

Release as a versioned, immutable process definition.

02 — Execute

Step-Based
Execution Engine

A robust state machine executes business processes with full lifecycle tracking, SLA monitoring, and event-driven triggers. Every transition is logged, every SLA breach is escalated, and every failed branch is compensated.

  • Persistent step-based state machine with error recovery, compensation handling, and pause/resume.
  • Per-step SLA thresholds with configurable breach detection, escalation actions, and multi-channel alerting.
  • Event-driven triggers: HTTP webhooks, cron expressions, scheduled timers, and internal Sanctum events.
  • Parallel branch execution with join semantics, deadlock detection, and automated compensation for failed branches.
03 — Verify

Append-Only
Audit Trail

Every process execution writes an immutable, append-only audit log with full traceability from trigger through every state transition to completion. Cryptographically chained entries, actor attribution, and tamper-evident export for compliance.

  • Cryptographically chained audit entries with precise timestamps and full actor attribution per event.
  • Per-instance execution trace showing every state transition — inputs, outputs, errors, and decisions.
  • Searchable audit viewer with filtering by process, actor, date range, status, and outcome.
  • Tamper-evident log export in machine-readable format for external compliance review and forensic analysis.

04 — Integrate

AI-Native
Integration

Connect intelligent agents directly into your process flows via Sanctum Flow's MCP server. Delegate decisions, classifications, and content generation to AI — with human-in-the-loop approval and complete data sovereignty.

  • Native MCP server enabling AI agents to create, advance, monitor, and complete process instances.
  • AI decision service task type: define a prompt, map inputs, let an LLM determine the next gateway route.
  • Human-in-the-loop approval steps with AI-generated recommendation summaries for faster reviewer decisions.
  • Automated process analysis: detect bottlenecks, suggest optimisations, and predict SLA breaches before they occur.
Capabilities

What the platform actually does.

BPMN 2.0 Visual Editor

Full specification support with bpmn-js canvas, drag-and-drop palette, element properties panel, and in-canvas simulation.

State Machine Engine

Persistent step-based execution with error recovery, pause/resume, compensation handlers, and parallel branch support.

Immutable Audit Log

Append-only event store with cryptographic chaining, per-instance execution traces, and tamper-evident compliance export.

MCP & AI Integration

Native Model Context Protocol server for AI agents to create, advance, and monitor process instances autonomously.

SLA Monitoring & Escalation

Per-step SLA thresholds with automatic breach detection, configurable escalation paths, and multi-channel alerting.

Event-Driven Triggers

Process instances can be launched via HTTP webhooks, cron schedules, scheduled timers, or internal Sanctum ecosystem events.

The Sovereignty Angle

Your Process Data
Never Leaves Your Infrastructure

Sanctum Flow runs entirely on your own servers. Process models, execution state, audit logs, and SLA data are stored in your database — never sent to a cloud BPMN vendor. No per-process licensing, no vendor lock-in, no workflow data mined for training models. Full export at any time.

Library

Cross-Industry
Process Library

Explore our growing catalog of 64 business processes modeled as OMG BPMN 2.0 flowcharts — spanning finance, HR, IT, sales, healthcare, manufacturing, and more. Each diagram is designed, executed, and published using Sanctum Flow.

  • 64 processes across 10 industry categories.
  • Every model conforms to OMG BPMN 2.0 specification.
  • Generated entirely by Sanctum Flow's AI-assisted modeler and converter.
  • New processes added regularly — request one for your business.
