About Kleidia

Self-hosted YubiKey & FIDO2 management for AD / Entra environments

What is Kleidia?

Kleidia is a self-hosted YubiKey & FIDO2 management platform designed specifically for European enterprises and government organizations. It runs in your own infrastructure (on-prem or your cloud) and integrates with AD / Entra ID and OIDC apps.

The name "Kleidia" comes from the Greek word for "keys" (κλειδιά), reflecting our focus on managing hardware security keys securely and efficiently.

Built For

  • European government agencies
  • Critical infrastructure & utilities
  • Regulated enterprises (finance, telco, healthcare)

Core Capabilities

  • End-User Self-Service - Users can safely reset PINs and manage certificates without opening tickets
  • FIDO2 & WebAuthn - Full support for modern passwordless authentication
  • Certificate Management - Automated PIV certificate enrollment and renewal
  • AD / Entra / OIDC Integration - Connects to your existing identity infrastructure
  • Complete Audit Trail - Every device operation is logged for compliance
  • Device Lifecycle - From registration to decommissioning

Why We Built Kleidia

Kleidia was founded by security professionals who experienced firsthand the frustration of managing YubiKeys at enterprise scale. The existing solutions shared common problems:

  1. User-based licensing - Costs that grow unpredictably with your organization
  2. Cloud dependencies - Your security data stored on third-party infrastructure
  3. Complex procurement - Difficult to budget and procure under EU regulations
  4. IT bottlenecks - Every PIN reset or lost key required helpdesk intervention

We built Kleidia to solve these problems with a fundamentally different approach: transparent flat-rate pricing, complete self-hosting, and end-user self-service.

Pricing Philosophy

Transparent, Fixed Pricing

€19,000/year

No user-based licensing. Unlimited users. Support during EU business hours included.

We rejected the industry standard of per-user licensing because:

With Kleidia's flat-rate model, you pay one price regardless of whether you have 100 or 10,000 users. Fixed annual pricing means one line item in your tender instead of per-user estimates, change orders and 'true-ups'.

Professional services and implementation projects quoted separately. Managed appliance option available for customers who prefer a fully managed Kleidia deployment.

Licence terms designed to fit standard EU public-sector contracts (no forced auto-renewal, no per-user audits).
