Security & Data Protection
How Ercel Security protects your data and our infrastructure.

Encryption & Infrastructure
Encryption
- TLS 1.3 for all connections in transit
- AES-256 encryption at rest (Supabase / PostgreSQL)
- No plaintext storage of sensitive data
- Payments via Stripe (PCI DSS Level 1) — no card data touches our systems
Infrastructure
- Isolated process with resource limits
- Firewall with reverse proxy (Caddy) — direct traffic blocked
- Automated health checks and monitoring
- SSRF protection: blocks localhost, private IPs, and metadata endpoints
- Graceful shutdown for zero data loss
Black-Box Methodology (External Assessment)
We assess your AI system from the outside, with no access to internal systems. Scan results are processed via Anthropic API to enrich findings with regulatory context (full details in our privacy policy).
- We only interact with publicly accessible system endpoints
- Text-only interactions via the public interface
- No access to source code, databases, or infrastructure
- Equivalent to what a real attacker or regulatory inspector would see
Data Protection (GDPR)
We follow strict data minimization and retention policies compliant with the General Data Protection Regulation.
- Assessment data automatically deleted after 90 days
- Immediate deletion request via [email protected]
- Prospect data anonymization after retention period
- No tracking cookies — only Plausible Analytics (privacy-first, no cookies)
Your rights
Under the GDPR, you have the right to:
- Access your personal data
- Rectify inaccurate data
- Erasure of your data
- Data portability
- Object to processing
- Restrict processing
