Risk Assessment Report – 2025

1. Executive Summary

Between 2025-03-01 and 2025-03-15, Clerk.io conducted its annual ISO 27001 risk assessment covering 42 information assets and 68 threat scenarios. A total of 21 risks were identified; 5 rated High, 10 Medium and 6 Low.

No Extreme (score 20-25) risks were discovered.

2. Methodology

The assessment followed the approved risk-assessment-methodology.md, using likelihood/impact scales (1-5) and risk score = L × I. Workshops were held with Engineering, SRE, Product, HR and Legal teams.

3. Key High Risks

ID Description Score Proposed Treatment
R-001 Credential stuffing against APIs 16 Rate limiting, bot/automation detection, breached-password checks, anomaly-based protections; keep MFA for employee/admin endpoints and promote SSO for customers
R-002 Single-region cloud outage 20 Automate restore and infra provisioning (Terraform/Ansible); strengthen backups and documented cross-region restore drills using replicated data (eu-central-1 -> eu-west-1)
R-003 Insider exfiltration 15 EDR, DLP, logging improvements

4. Residual Risk & Acceptance

Implementation of controls in the Risk Treatment Plan is expected to reduce all high risks to ≤8 within the next six months. Acceptance for residual risk R-005 was granted by CEO on 2025-03-28.

5. Conclusion

Clerk.io's risk exposure is within the defined appetite once planned treatments are completed. Progress will be tracked via bi-monthly ISMS reviews.
