Product guideSelf-hosted

Horizon Platform

Self-hosted AI management platform for operations, governance, and security-focused teams. Telemetry comes from one cross-platform agent shipped in three modes — full Horizon (fifteen-collector operational telemetry), Cyber (Cyber Essentials Plus A4–A8 evidence and CIS-style topology), and ESG (Scope 2 evidence on the DESNZ factor) — across Windows, macOS, Linux, Proxmox, and pfSense. Same installer, same signed update channel, same outbound-only path; the collector set is rotated to fit the question each host is answering and enforced server-side on every check-in.

02 · Use cases

What teams actually use it for.

  • Unified operations across agents, tickets, alerts, and change workflows.
  • Cyber Essentials Plus A4–A8 self-assessment evidence with hostname/IP traceable per control.
  • Scope 2 emissions reporting with GHG Protocol dual reporting (location-based on DESNZ; market-based with REGO).
  • Cross-platform fleet management — Windows, macOS, Linux, Proxmox, pfSense.
  • AI-model presence inventory and Hermes AI project context across the fleet.
  • Software-EOL flagging via endoflife.date pre-populating CE+ A6.6.

03 · Pricing

What you'd pay.

Self-hosted deployment model. Cost profile depends on infrastructure footprint, feature scope, and operational requirements.

Core platform deployment

Project scoped

Platform baseline with dashboard, fleet management, and core operations workflows. Includes the full Horizon agent on operator-managed hosts and a UK-hosted Postgres backend with 90-day default retention.

Cyber-mode rollout

Project scoped

Adds the Cyber agent for CE+ A4–A8 readiness and the IASME-shaped PDF export. Software-EOL flags via the endoflife.date community database for fifteen security-critical packages.

ESG-mode rollout

Project scoped

Adds the ESG agent for measured kWh, Scope 2 emissions (location-based via DESNZ; market-based with your REGO certificate reference), and SECR intensity reporting.

No mandatory token subscription. Any external model or integration usage scoped separately. Hosts can be moved between agent modes by issuing a new install token; mode is enforced server-side.

04 · Business fit

What to know before you commit.

It fits when

  • 01 Self-hosted architecture with full data sovereignty by default; no third-party egress.
  • 02 One agent, three modes — same installer, server-enforced scope per host.
  • 03 Outbound-only HTTPS, signed update channel with SHA-256 verification, one-line uninstall.
  • 04 CE+ readiness export shaped to IASME question-order; auditor-traceable per endpoint.
  • 05 ESG figures use the current DESNZ Government GHG factor (0.207 kg CO2e/kWh) with REGO support.
  • 06 Multi-tenant super-admin with pinned company picker.

It doesn't fit when

  • 01 Requires local infrastructure and operational ownership.
  • 02 Setup includes Docker, PostgreSQL, Redis, and secure secret management.
  • 03 Cyber agent is observability-only — no remote-control surfaces by design.
  • 04 ESG scope is Scope 2 only; Scope 1 and Scope 3 are out of scope.

When it makes sense

Best for organisations that need practical AI operations while retaining local control over data, infrastructure, and governance — especially where CE+ readiness and Scope 2 evidence both matter.

05 · Data handling

Where your data goes.

Summary

Self-hosted by design. Operational telemetry, audit trails, and AI workflow data stay inside your perimeter on a UK-hosted Postgres backend. Default retention 90 days.

GDPR · Compliance

Supports compliance-led deployment; final compliance posture depends on access controls, retention policy, and the customer's implementation. Evidence trail is auditor-friendly.

Sovereignty

Full data sovereignty in self-hosted mode. Outbound-only HTTPS to the portal; no third-party egress required for any of the three agent modes.
