Security

Enterprise Security, Zero Compromise

A security architecture designed from the ground up for European enterprises. Zero-trust, end-to-end encryption, and compliance certifications that actually mean something.

Security at Every Layer

Comprehensive protection from infrastructure to application, designed to meet the needs of regulated industries.

Zero-Trust Architecture

Every access request is verified regardless of origin. Network location alone never grants trust — identity, device health, and context are validated continuously.

Advanced Threat Protection

AI-powered email filtering, malware sandboxing, and real-time URL scanning. Block phishing, ransomware, and zero-day exploits before they reach your users.

Data Loss Prevention

Classify sensitive data automatically, enforce policies across email and file sharing, and prevent accidental or malicious data exfiltration in real time.

End-to-End Encryption

AES-256 encryption at rest, TLS 1.3 in transit. Optional customer-managed encryption keys give you full control — we never have access to your plaintext data.

Identity & Access Management

SAML 2.0 and OIDC single sign-on, adaptive multi-factor authentication, conditional access policies, and directory synchronisation with your existing identity provider.

Audit Logging & SIEM

Comprehensive audit trails for every action. Export logs to your SIEM via syslog, webhook, or API. Tamper-proof storage with 7-year retention available.

Encryption

Customer-Managed Encryption Keys

With customer-managed keys, your data is encrypted with keys that only you control. Even UnionStack engineers cannot access your plaintext data — by design, not by policy.

  • AES-256 encryption at rest for all stored data
  • TLS 1.3 for all data in transit
  • Customer-managed keys via HSM integration
  • Key rotation and lifecycle management
  • Zero-knowledge architecture option
