Supplier Security Scorecard for Local Councils
Local councils work with dozens — sometimes hundreds — of technology suppliers, each with access to council systems or resident data. The Suffolk County Council breach and the MOVEit supply chain attack demonstrate that supplier security failures directly expose councils to data breaches and ransomware. This scorecard provides a structured framework for assessing and rating council technology suppliers.
Supply chain attacks exploiting trusted supplier relationships affected hundreds of UK public sector organisations — councils must actively manage supplier security risk.
How to Use the Supplier Security Scorecard
Apply this scorecard to all suppliers with access to council systems or resident data. Tier your suppliers by risk — those with direct access to sensitive data or administrative system access require the most rigorous assessment. Use the scorecard outputs to prioritise remediation discussions and contractual requirements.
Key Supplier Assessment Areas
The scorecard assesses suppliers across five areas:
- Certification and accreditation — Cyber Essentials, ISO 27001, or equivalent
- Technical controls — MFA, encryption, patch management, incident response
- Data handling — GDPR compliance, data processing agreement, retention policies
- Access management — how is access to council systems granted, monitored, and revoked
- Incident notification — contractual obligation to notify council within required timeframes
Frequently Asked Questions
Do councils need to assess every technology supplier?
Apply a risk-based approach: tier suppliers by the access and data they can reach. Tier 1 (highest risk) — suppliers with direct access to systems holding special category data or administrative access to council infrastructure — require the most rigorous assessment. Tier 2 (medium risk) — suppliers accessing personal data — require standard assessment. Tier 3 (lower risk) — suppliers with no data access — require lighter-touch review.
