The defense industry's most advanced software verification solution.

CONNECTING DISPARATE SYSTEMS IS RISKY AND SLOW

Misaligned schemas cause costly, avoidable failures.

Design modular interfaces

Capture interface rules once, in one place, using the standards your program mandates.

Scattered interface specs

Interface rules and architecture diagrams are scattered across documents and slide decks.

Models that lag the code

Design models lag behind development and don’t specify interfaces in enough detail.

Test integration code

Test integration code against your interface contracts, automatically.

Verify behavior continuously

Emulate the rest of the system and verify component behavior on every build.

Missed defects in testing

Defects only surface late and in the lab due to not being able to test properly beforehand.

Prove compliance with a digital thread

Maintain traceability from design to code to testing, with usable evidence.

Review packets that take weeks

Review packets require manual effort and take weeks to compile.

Design

Define Your System Architecture

  • Rapidly design system interfaces within an intuitive, drag-and-drop interface
  • Visualize end-to-end data flows and message sequences to understand behavior before integration.
  • Perform component-based design with semantic precision

Verify

Ensure Correct Behavior

  • Automatically check interfaces for compliance
  • Emulate other components for black-box testing
  • Integrate with CI/CD pipelines for automated verification

MISSION-READY

Built for defense standards

  • MOSA-native workflows.
  • Out-of-the-box checks for OMS and WOSA
  • WOSA Development Kit provides WOSA-aware modeling and verification accelerators.

Integrates with your tools

  • CI/CD: Tangram Pro integrates with your CI/CD pipeline to prove software performance.
  • Containers: Tangram Pro supports verification testing with any OCI-compliant software container.
  • Cameo Integration turns MBSE artifacts into concrete interface contracts that engineers can actually use.

Flexible deployment and security

  • Cloud-native solution with support for IL5/IL6 environments. Options for deploying on-premises, air-gapped, or in AWS GovCloud.
  • SSO/OIDC, RBAC, audit logging, encryption in transit and at rest.
  • CUI/ITAR-capable workflows.

CORE CAPABILITIES: DESIGN

Design at every layer

Standards-aware libraries

Start from OMS 2.x, WOSA, FACE, STANAG 4586, MAVLink, UMAA, ROS, and program GRAs; enforce interface best-practices with a single source of truth and built-in validation rules.

Data contracts

Author precise message schemas (fields, units, enums, optionals, lists and invariants). Capture logical properties and assertions for verification.

API and service contracts

Rigorously define component interfaces, explore endpoints/schemas, associate specs to components, and diff versions as APIs evolve.

Data flow mapping

Map end-to-end request/response flows between components, annotate steps, and walk through the flow to spot gaps and issues.

Messaging and transport

Specify topics/queues and serialization across ZeroMQ, ActiveMQ, RabbitMQ, Kafka, NATS, TCP/UDP.

Sequence and intent

Declare expected message directions, topics, and sequencing at the interface, ready for validation during verification.

CORE CAPABILITIES: VERIFICATION

Verify thoroughly

Ensure Contract conformance

Run your component in a container while Tangram Pro emulates the rest of the system. Check message types, order, topics, serializers, and transports against your interface design.

Verify continuously in CI/CD

Drive tests via API/CLI in GitHub Actions, GitLab CI, or Jenkins; continuously gate builds on sequence satisfaction.

Produce evidence and traceability

Link Design → Tests → Results; export reviewer-friendly JSON/DOCX/PDF evidence aligned to program standards.
