## Platform

- [Platform](https://www.planetb2b.com/platform): Planet B2B is a multi-tenant collaboration platform for regulated B2B commerce. Agencies and initiative offices find and shortlist suppliers in an AI-searchable catalogue, run delivery through stage-gated projects, and keep organisational knowledge in a classification-aware repository — all on one identity model, with database-enforced tenant isolation and a tamper-evident audit trail underneath.
- [Security](https://www.planetb2b.com/security): Security posture that is implemented per module is only as strong as the module that forgot. Planet B2B enforces tenancy, access and audit beneath the modules, so every capability inherits the same guarantees by construction rather than by discipline.
- [Deployment](https://www.planetb2b.com/deployment): The same platform runs as managed SaaS, in a dedicated cloud with your own keys, or fully on-premises and air-gapped. The deployment model is a procurement decision, not a product decision — you do not lose modules by choosing isolation.

## Sectors

- [Defence](https://www.planetb2b.com/defense): Defence initiatives do not fail their audits because someone lacked a Kanban board. They fail because the trail runs cold at a system boundary — the supplier record lives in one tool, the evaluation in another, the licence determination in a spreadsheet, and nothing reconciles. Planet B2B keeps sourcing, delivery and documentation in one tenancy with one append-only audit trail.
- [EU public sector](https://www.planetb2b.com/public-sector): European public procurement has its own vocabulary, its own classification system and its own data-residency expectations. Planet B2B treats those as first-class rather than as a localisation afterthought.
