Overview
A leading UK financial services organisation engaged C4C Group to address a growing challenge: understanding and managing data movement risk caused by people — both accidental and intentional.
Despite strong perimeter security, the business lacked visibility into how sensitive data was being handled, shared, or exfiltrated by employees and contractors.
The engagement formed part of the client’s broader human risk management strategy — focusing on how people interact with data and how behaviour can expose the business to potential breaches.
To solve this, C4C implemented Mimecast Incydr, a powerful insider risk management platform designed to detect, prioritise, and respond to data exposure events — giving the organisation the clarity it needed to act decisively.
The Challenge
The client’s existing security stack protected against external threats but offered limited insight into internal and behavioural risk.
Key challenges included:
- Unmonitored data movement: Employees transferring sensitive files via personal cloud apps or USB devices.
- Human risk blind spots: The organisation lacked visibility into risky user behaviour, including misuse of data and unsanctioned sharing.
- Limited visibility: Security teams couldn’t distinguish between normal activity and potential insider threats.
- Compliance exposure: Regulators required evidence of data protection and risk governance.
The organisation needed a partner who understood both technology and human behaviour not just another product deployment.
The Solution
C4C Group deployed Mimecast Incydr to provide continuous, contextual visibility into how data moved within and outside the organisation.
Our approach combined Mimecast Incydr’s behavioural analytics with C4C’s human risk framework, enabling the client to identify and address data risks driven by people — whether accidental or intentional.
Implementation included:
- Discovery and baselining of normal user file activity.
- Integration with endpoint and cloud environments (Microsoft 365, Google Drive, Box, etc.).
- Custom risk scoring and alerting based on data sensitivity and user roles.
- Workflow automation for triaging incidents and escalating genuine insider threats.
Using C4C’s IDEAL Framework, the solution was aligned with business priorities — ensuring technology, people, and process worked together seamlessly.
The Outcome
Within 90 days of deployment, the organisation achieved:
✅ 80% reduction in unmonitored file transfers
✅ Full visibility of data movement across endpoints and cloud platforms
✅ Improved compliance readiness with auditable incident records
✅ Enhanced security culture through greater awareness of data-handling behaviour
By focusing on human risk and behavioural visibility, Mimecast Incydr transformed how the organisation understood and managed insider threats — turning everyday employee activity into actionable intelligence.
