Security Practices

Last updated · 19 June 2026

Overview

At Stazion, security is fundamental to our mission of helping sales teams turn their own documents into proposals, quotes, and RFQ/RFx responses. This document describes the technical and organizational measures we implement to protect your data.

Stazion ApS (CVR 46244028) is based at Husumgade 31, 4. 15, 2200 København N, Denmark. This document complements our Privacy Policy and Data Processing Agreement.

Security Principles

Our security approach is built on:

  1. Defense in Depth: Multiple layers of security controls
  2. Principle of Least Privilege: Access limited to what is necessary
  3. Privacy by Design: Data minimization at every step
  4. Tenant Isolation: Each organization's data is separated at the database level
  5. Transparency: Clear communication about our practices

Data Encryption

Encryption at Rest

Data TypeEncryption Method
Integration credentials (Microsoft OAuth tokens)AES-256-GCM authenticated encryption
DatabaseSupabase (PostgreSQL) encryption at rest (AES-256)
File StorageSupabase Storage encryption at rest (AES-256)
BackupsEncrypted automated backups

Key Management:

  • Encryption keys are managed separately from the data they protect
  • Application-level secrets are stored outside the codebase as environment configuration
  • Sensitive credentials are never written to logs

Encryption in Transit

ConnectionProtocol
User to ApplicationTLS (HTTPS enforced)
Application to DatabaseTLS encrypted connection
Application to APIsTLS for all external APIs
Application to AI providersTLS for all model and embedding calls

Certificate Management:

  • Certificates are automatically managed and renewed by our hosting platform
  • HTTPS is enforced across the application
  • Modern cipher suites only

Authentication & Access Control

User Authentication

  • Supabase Auth: User sign-in is handled by our authentication provider
  • Password Security: Passwords are hashed by the authentication provider and never stored in plain text
  • Microsoft OAuth 2.0: Used to connect Microsoft 365 for sending email and Teams messages; OAuth access and refresh tokens are encrypted at rest
  • Session Management: Secure HttpOnly session cookies with automatic expiration
  • CSRF Protection: OAuth state is protected against cross-site request forgery

Authorization

ControlImplementation
Role-Based Access ControlDefined roles (owner, admin, member) with specific permissions
Organization IsolationMulti-tenant data separation enforced by row-level security
Audit TrailSensitive RFQ lifecycle actions recorded as audit events
Privileged ActionsDestructive RFQ mutations require owner or admin role

Internal Access Control

  • Employee Access: Strictly limited to operational necessity
  • Production Access: Restricted to authorized personnel
  • Vendor Access: No direct access to customer data
  • Access Termination: Access promptly revoked when no longer required

Infrastructure Security

Cloud Platform

We host our infrastructure on enterprise cloud platforms, leveraging their security controls:

ComponentProviderSecurity Features
Application HostingVercel (serverless)Managed runtime, automatic patching, isolated execution
DatabaseSupabase (PostgreSQL)Row-level security, encryption, automated backups
File StorageSupabase StorageAccess control, encryption at rest
Document ExtractionGoogle Cloud Document AIManaged, EEA-region processing

Data Location: The Controller's core data (account data, documents, and search indexes) is hosted within the European Economic Area (EEA). Database and storage are hosted in the EEA via Supabase; application hosting is in the EEA (Stockholm, Sweden) via Vercel.

Network Security

  • Managed Network Controls: Application components run on managed cloud networks with platform firewalling
  • DDoS Protection: Provided by our hosting platform
  • Restricted Ingress: Only necessary endpoints are exposed

Platform Security

  • Managed Runtime: Serverless managed environment
  • Automatic Updates: Security patches applied by the platform
  • Resource Isolation: Function-level and container-level isolation

Application Security

Secure Development

PracticeDescription
Code ReviewChanges reviewed before merging
Dependency ManagementDependencies kept current and monitored for vulnerabilities
Static AnalysisLinting and TypeScript strict mode enforced
TestingAutomated unit and end-to-end test suites
Build VerificationPreflight and build-safety checks before deployment

Input Validation

  • Zod Schemas: API inputs validated with strict schemas
  • SQL Injection Prevention: Parameterized queries and a managed Postgres client
  • XSS Prevention: React's built-in escaping
  • CSRF Protection: State protection on OAuth and state-changing operations

API Security

  • Authentication Checks: Server routes verify the authenticated user before processing
  • Input Size Limits: Maximum payload sizes enforced
  • Error Handling: Generic error messages to users, with details logged internally
  • Rate Limiting: Throttling applied to high-volume AI processing paths

Data Protection

Data Minimization

We collect only the data necessary to provide our service:

Data CategoryWhat We CollectWhat We DON'T Do
AccountEmail, display name, role, organizationStore passwords in plain text
DocumentsFiles you upload and the content extracted from themUse your content to train AI models
RFQ/RFxLine items, quotes, feedback, communications you sendRead content unrelated to the workflow
AnalyticsUsage events and session identifiers (production only)Run analytics on local or dev environments

AI Processing

Document analysis, extraction, proposal generation, and search rely on third-party AI providers (Anthropic, OpenAI, Cohere, and Google Document AI). Relevant content is transmitted over TLS for processing. We do not use your content to train our own or any third party's general-purpose AI models, and our AI subprocessors are engaged under terms that prohibit using your content to train their models.

Data Retention

Data TypeRetention Period
Account DataWhile the account is active
Organization DataWhile the subscription is active
Uploaded Documents and Extracted ContentWhile the account is active, or until deleted
Integration TokensUntil the integration is disconnected
AnalyticsUp to 12 months
LogsLimited period for security and troubleshooting

Data Deletion

  • User Request: Personal data deleted within 30 days of a verified request
  • Account Termination: Data deleted within 30 days after the export period
  • Document Deletion: Deleting a document removes its content and search indexes

Monitoring & Incident Response

Security Monitoring

CapabilityImplementation
Audit LoggingSensitive actions (for example RFQ lifecycle events) recorded

Incident Response

Response Process:

  1. Detection: Automated monitoring or reported incident
  2. Triage: Assess severity and scope
  3. Containment: Isolate affected systems
  4. Investigation: Determine root cause
  5. Remediation: Fix the vulnerability and restore service
  6. Notification: Notify affected parties per DPA requirements
  7. Post-Mortem: Document lessons learned

Notification Timeline:

  • Customer notification: Without undue delay, and no later than 48 hours after a confirmed Security Incident (per our DPA)

Compliance Roadmap

We are actively working to strengthen our security posture and pursue formal certifications (such as SOC 2 and ISO 27001) as we grow. Contact us for our current security assessment status or to complete a vendor security questionnaire.


Vendor Security

Subprocessor Assessment

Third-party vendors are reviewed for their security and privacy practices, and are bound by Data Processing Agreements before processing personal data on our behalf.

Current Subprocessors

A full list of subprocessors, including purpose, data categories, location, and transfer mechanism, is maintained in Annex B of our Data Processing Agreement. Core data stores (Supabase, Vercel, Google Cloud) are EEA-hosted; US-based AI and integration providers rely on Standard Contractual Clauses and/or the EU-US Data Privacy Framework.

Security FAQs

Do you store my password?

No. Sign-in is handled by our authentication provider, which stores only a hashed version of your password. We never store passwords in plain text.

Do you use my documents to train AI models?

No. Your documents and queries are processed only to provide the Service. We do not use your content to train our own or any third party's general-purpose AI models, and our AI providers are contractually prohibited from using it to train theirs.

Where is my data stored?

Your core data (account data, uploaded documents, and search indexes) is hosted within the European Economic Area (EEA). Some AI processing providers are located outside the EEA, including in the United States, and are covered by appropriate transfer safeguards.

Who at Stazion can access my data?

Only authorized personnel with a legitimate operational need can access production systems.

Is my organization's data separated from other customers?

Yes. Each organization's data is isolated at the database level using row-level security, so one organization cannot access another's data.

What happens if Stazion is acquired?

Your data will be handled according to the Terms of Service and Data Processing Agreement. You would be notified of any ownership change.
