Horizon Is Now Generally Available for Microsoft Dynamics 365

Your reputation ships with every Microsoft update

Today, Horizon is generally available.

Horizon is the enterprise validation platform built exclusively for Microsoft Dynamics 365. It helps teams create production-ready tests, validate complete business processes, and stay ready for every Microsoft release.

If you run Dynamics 365, you already understand the problem Horizon solves. Microsoft controls the release schedule. Major release waves, continuously serviced applications, and regular updates do not pause for your test plan.

Each release can affect the configurations, customizations, integrations, and ISVs your business depends on. The question is no longer whether the update ships. It is whether everything still works when it does.

Traditional script-based testing was not designed for this pace of change. Recorded automation breaks when forms and fields move. Teams that spend each release repairing tests are not expanding coverage. Testing also happens too late, after the build is assembled and the release is already moving toward production.

That gap is where go-lives slip and regressions escape.

Horizon closes it.

What Horizon does

Horizon is purpose-built for Dynamics 365. Every architectural decision begins with the Dynamics 365 data model, applications, integrations, and business processes. Included in this release:

Instant Test Creation

Generate production-ready tests in minutes with AI-powered, intent-based authoring. Business and technical teams can define what should happen, and Horizon builds the validation without scripting. Most customers run their first production test on day one of onboarding.

Deterministic execution

AI powers authoring. Execution remains deterministic, repeatable, and auditable. No AI makes pass or fail decisions during production runs.

Autonomous maintenance

Horizon’s five-layer self-healing engine adapts validations as forms, fields, and metadata change. Coverage stays current through Microsoft updates, with every adjustment logged for review.

Headless Validation

Validate Dynamics 365 APIs, OData services, business logic, and live data directly. No browser, extensions, or test infrastructure required. Teams can identify defects at the API layer before they reach UAT or production.

End-to-end workflow validation

Combine user interfaces, APIs, integrations, connected applications, and AI agents into complete business-process validation from one platform.

Built for what comes next

The future of ERP is continuous.

Dynamics 365 is becoming more connected, more intelligent, and more central to how enterprises operate. AI is changing both how tests are created and what organizations need to validate.

Horizon uses AI where it creates the most value: capturing intent and generating production-ready tests. Execution remains deterministic where proof, repeatability, and auditability matter.

Microsoft is also introducing agents across Dynamics 365applications. These agents can act on enterprise data and influence critical business processes. Horizon validates agent inputs, outputs, decisions, and complete workflows with the same audit trail and rigor used across the rest of the environment.

The results show up where they matter. One global manufacturer told us that upgrade validation once required seven people overtwo weeks. With Horizon, one person completes it in a few days.

That is the difference between testing as a bottleneck and validation as a release accelerator.

“The future of ERP is continuous. Dynamics 365 is becoming more connected, more intelligent, and more central to how enterprises operate. Horizon gives business and technical teams a practical way to innovate continuously, making more use of their Dynamics 365 investment, while keeping validation predictable, auditable, and secure.”

“The engineering principle behind Horizon was simple. AI should help customers create tests faster, but production execution must remain predictable and trusted. That is why AI powers authoring while every validation runs deterministically with repeatable results and a complete audit trail. Headless Validation also allows teams to shift left by validating APIs, data, integrations, and business logic before issues reach the user interface or UAT.As AI agents take on more work inside Dynamics 365, Horizon validates them with the same rigor as every other business process.”
