Reducing human risk with Mimecast Incydr

Leading UK financial services organisation

How C4C Group helped a leading financial services organisation cut insider data risk by 80 percent using the behavioural visibility of Mimecast Incydr.

80%fewer unmonitored file transfers
90 daysto measurable results
Fullendpoint and cloud visibility

The challenge

The client had strong perimeter security but little insight into internal and behavioural risk, how its own people were handling and moving sensitive data.

The solution

C4C deployed Mimecast Incydr for continuous, contextual visibility of how data moved inside and outside the organisation, combined with our own human risk framework and aligned to the business through the IDEAL framework.

Delivered through our IDEAL framework, the disciplined method behind every C4C engagement.

  1. IdentifyDiscovered and baselined normal user file activity so genuine risk could be told apart from everyday work.
  2. DecideBuilt custom risk scoring based on data sensitivity and user role, deciding what actually warranted attention.
  3. ExecuteDeployed Incydr and integrated it across endpoint and cloud, including Microsoft 365, Google Drive and Box.
  4. AdoptEmbedded workflow automation to triage incidents and escalate only genuine threats, so the programme fitted how the team works.
  5. LifecycleKept auditable incident records and an ongoing review of risk posture to sustain compliance readiness over time.

The outcome

Within 90 days of deployment the organisation turned everyday employee activity into a managed, visible risk surface.

Why C4C Group

Frequently asked questions

What is Mimecast Incydr and what does it do?

Incydr is an insider risk and data exfiltration tool. Rather than guarding the perimeter, it watches how your own people move files across endpoints and cloud apps, then scores that activity by data sensitivity and user context so genuine risk stands out from normal work.

How quickly can an insider risk programme show results?

Sooner than most expect. In this engagement the organisation reached measurable results within 90 days, because the early value comes from visibility. Once you can see how data actually moves, the highest risk behaviours surface almost immediately.

Is insider risk really a bigger problem than external attacks?

It is not bigger, it is blinder. Most organisations invest heavily in perimeter defence and very little in understanding internal data movement, so the insider path is where the unseen exposure usually sits. The point is balance, not replacing one with the other.

Does monitoring employees damage trust?

It does not have to. The aim is visibility of data movement, not surveillance of people. A well run programme is transparent about what is monitored and why, scores on risk rather than suspicion, and escalates only genuine threats, which protects employees as much as the business.

How do you tell a real insider threat from normal activity?

By baselining first. You establish what normal file activity looks like for each role, then weight events by data sensitivity and context. A finance user touching finance data is expected, the same file leaving to a personal cloud account is not.
