Sound familiar?
If any of these ring a bell, you are in the right place.
Credentials scattered everywhere
API keys, passwords, and tokens spread across .env files, Slack messages, and spreadsheets — one leak away from a breach.
Paying per user for Auth0 or Okta
100 users = €2,000+/month. Enterprise IAM tools price growing teams out of the market.
Your data is on US servers
Schrems II, GDPR, and NIS2 require EU data residency. US-hosted services put you at regulatory risk.
Encryption that will not last
RSA and ECC will be broken by quantum computers. NIST standardised replacements in 2024 — most stacks have not caught up.
Three Products, One Platform
QuantumKeys
Encryption-as-a-Service
RESTful API for ML-KEM encryption, ML-DSA signatures, and quantum random number generation.

Make your first encryption call
POST your plaintext and receive ML-KEM-768 quantum-safe ciphertext in milliseconds.
curl https://api.quantumapi.eu/v1/encrypt \
-H "Authorization: Bearer YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{
"algorithm": "ML-KEM-768",
"plaintext": "sensitive-data"
}'// Response
{ "ciphertext": "MIIBIjANBgkqhkiG9w...", "keyId": "k_7fG2" }Enterprise Identity & Access Control
Fine-grained security model from organization-level roles down to individual record permissions.
Identity Federation
Connect your existing identity provider and let users authenticate with their corporate credentials.
- Entra ID, Okta, Google Workspace
- OIDC protocol (SAML 2.0 coming soon)
- Automatic user provisioning
Record-Level Permissions
Go beyond roles. Define exactly who can access what, down to individual vault entries and API operations.
- Built-in roles: Owner, Admin, Developer, Viewer
- Custom access policies per resource
- API keys scoped to specific vault records
User & Resource Groups
Organize users and resources into groups for simplified, scalable access management.
- Group users by team, department, or project
- Group resources for bulk permission assignment
- Nested groups for complex hierarchies
Multi-Tenant Architecture
Every user gets a free personal tenant. Join multiple organizations with different roles in each.
- Free personal tenant for every account
- Multiple tenants with independent roles
- Complete data isolation between tenants
Enterprise-Grade Security
NIST Standardized
All algorithms comply with FIPS 203, 204, and 205 standards published by NIST.
Real Quantum Entropy
True random numbers generated by Quantum Blockchains quantum hardware (EU, Poland).
EU Sovereignty
All data processed and stored in EU data centers. Scaleway infrastructure in France and the Netherlands, expandable to Poland.
Developer-First
RESTful API and comprehensive documentation for rapid integration. Client SDKs coming soon.
Role-Based Access
Multi-tenant architecture with granular permissions, groups, and access policies.
Compliance Ready
GDPR compliant, NIS2 ready, with complete audit logs for regulatory requirements.
"But TLS 1.3 Already Has PQC..."
TLS protects your data in transit. We protect it everywhere else.
TLS 1.3 with post-quantum key exchange secures the connection between two endpoints. But once data arrives at its destination, TLS stops. Your secrets, keys, passwords, and sensitive data sit in databases and vaults protected by classical encryption — still vulnerable to quantum attacks.
Quantum-Resistant Algorithms
All algorithms follow NIST FIPS 203, 204, and 205 standards.
Key Encapsulation (KEM)
Digital Signatures
+ AES-256-GCM for authenticated symmetric encryption (FIPS 197)
Simple, Transparent Pricing
Start free, scale as you grow. All plans include every PQC algorithm.

Who’s behind QuantumAPI?
We are a small team based in Dublin, Ireland, building security infrastructure we wish had existed when we were building products ourselves.
Victor Zaragoza
Founder & CEO
Victor built QuantumAPI to solve problems he faced while building previous SaaS products: the cost and complexity of enterprise IAM tools, and the lack of accessible post-quantum cryptography for European companies.
