🛡️
ISO 27001 Certification in Progress
Committed to the highest international standards of Information Security

Security & Data Protection Safeguards

Defense-in-depth controls from the edge to the user's device, aligned with Art. 32 of the GDPR (DSGVO), the BSI C5 catalogue and TISAX good practices.

🇩🇪
Data residency & sovereignty
Production infrastructure exclusively in German regions, with backups and logs kept within the same geographic border.
  • Primary region: Frankfurt am Main; secondary in another German zone or, when unavailable, in another EU country under Standard Contractual Clauses.
  • Backups, replicas, logs and derived artifacts remain within the same geographic border.
  • Compliance with the requirements of the GDPR (DSGVO) and the BDSG.
  • Data under special regimes (healthcare, legal, financial) receive additional controls aligned with BSI C5 and TISAX good practices.
🛡️
Edge layer — Cloudflare
First defense perimeter, with traffic preferably terminated at German PoPs.
  • DDoS mitigation at layers 3, 4 and 7, with capacity above 200 Tbps on the global network.
  • Web Application Firewall (WAF) with managed rules for OWASP Top 10, zero-day CVEs and custom per-application rules.
  • Bot Management and Rate Limiting to contain API abuse, credential stuffing and scraping.
  • TLS 1.3 with modern ciphers (AEAD), HSTS preload and automatic certificate rotation.
  • Cloudflare Data Localization Suite: inspection, encryption keys and logs remain within EU/German territory.
  • Zero Trust Access for administrative access, replacing traditional VPNs with contextual authentication and mandatory MFA.
🔒
Server-side security
Defense-in-depth controls from the operating system to secrets and identity management.
  • Encryption at rest with AES-256 across volumes, databases and backups; keys managed via a regional KMS (Germany) with periodic rotation and separation of duties.
  • Encryption in transit with mandatory TLS 1.2+ between all services, including internal communication (mTLS where applicable).
  • OS hardening following CIS benchmarks, with automated patching and controlled maintenance windows.
  • Network segmentation via private VPC, security groups and network policies; no data resource is exposed directly to the internet.
  • Identity & access based on least privilege, RBAC, MFA for administrative access and periodic permission reviews.
  • Immutable audit logs, centralized, with a minimum retention of 12 months and SIEM integration.
  • Secrets management via a dedicated vault (HashiCorp Vault or cloud-native equivalent), with no credentials in code or exposed environment variables.
  • Continuous vulnerability scanning across container images, dependencies and infrastructure, with SLAs defined by CVSS severity.
📱
Client, MFA & mobile access
Server-grade controls on the browser and the app, with MFA mandatory across all channels.
  • HTTPS enforced, HSTS preload, strict CSP and security headers (X-Content-Type-Options, Referrer-Policy, Permissions-Policy, frame-ancestors).
  • Session cookies with HttpOnly, Secure and SameSite, short lifetime and rotation after authentication or privilege elevation.
  • CSRF protection via synchronized tokens and Origin/Referer validation.
  • MFA mandatory on first access on any device, including mobile — no exceptions.
  • Passkeys / WebAuthn as the preferred factor, bound to the Secure Enclave (iOS) or StrongBox/Keystore (Android): phishing-resistant, with local biometrics.
  • TOTP (RFC 6238) as a portable alternative; push with number matching against MFA fatigue; SMS only as last-resort recovery.
  • Adaptive (risk-based) MFA: re-required on context changes (new IP, geolocation, device) or sensitive actions.
  • Step-up authentication for critical operations (signatures, profile changes, export of sensitive data).
  • Administrative access requires hardware-bound passkey/WebAuthn, with no downgrade to weaker factors.
  • Corporate SSO via OIDC/SAML (Azure AD/Entra ID, Okta, Keycloak), preserving the customer's internal MFA policies.
  • Mobile sessions with rotated, individually revocable refresh tokens; trusted device registry with remote revocation.
  • Jailbreak/root detection in sensitive apps and certificate pinning against interception by malicious proxies.

The absence of MFA on mobile channels is currently considered below the state of the art in Germany and may be interpreted by the BfDI and state-level authorities (Landesdatenschutzbehörden) as a failure to implement Art. 32 of the GDPR. Our controls position the operation above the regulatory baseline and aligned with practices audited under:

GDPR / DSGVO BDSG BSI C5 ISO 27001 TISAX
