A security posture engineered for resilience

Security is built into the platform architecture - not layered on top. Every design decision, from data isolation to API authentication, was made with enterprise and regulated-environment requirements in mind.

Our multi-tenant architecture provides strict logical separation. Your marketplace data resides in a secure, dedicated, and isolated environment. Data from one operator is never accessible to or commingled with another.

Validated Isolation

Rigorous access controls, including Multi-Factor Authentication (MFA), Single Sign-On (SSO), and granular Role-Based Access Controls (RBAC), ensure system access is granted only to verified users

Authentication & Access Controls

Every API endpoint is authenticated and authorised. The integration layer between your stack and ours doesn't create exposure — it's where security controls are most precisely applied.

Integration Security

Personally Identifiable Information is redacted by default. Marketplace operators define granular controls over which roles can view PII, giving you full governance over sensitive buyer and vendor data within your platform.

Data Security

Regular internal security reviews hold our ways of working to the same standard as our technology. SOC2 and ISO 27001 certification in progress for 2026.

Continuous Internal Auditing

A platform developers can trust at scale

For technical teams

Arcadier is not a black box. Whether you are a technology partner, enterprise technical team or an agency building for clients, your team can understand, extend, and build on it with confidence.

Comprehensive documentation for developers

Over 150+ APIs. REST APIs across every platform component, from catalogue, orders, users, commissions, and events all fully documented and accessible from the developer portal. Your engineers stay in control of how data flows and how experiences are composed.

Build your way, without the restrictions

Go headless and build a fully custom frontend, or deploy Arcadier's templates and customise from there. Technology teams can build differentiated solutions without fighting the platform. Enterprise teams get a system that evolves with their architecture, not against it.
