Case Study: Royal Cosun achieves 99% reduction in phishing and near‑elimination of spam with Mimecast

Royal Cosun Cultivates Global Defenses With Mimecast

Royal Cosun, an international agri‑food cooperative with about 4,000 employees and €2.3 billion in annual revenue, faced rising email threats—spam, phishing, impersonation and business‑email‑compromise attacks—that its legacy gateway could no longer block. Protecting business continuity and the global food‑supply operations made improving email security a top priority.

Cosun deployed Mimecast’s Secure Email Gateway, Targeted Threat Protection, Internal Email Protect and Impersonation Protect in a phased rollout aligned with its move to Office 365. The result: spam and phishing tickets fell from several per week to one or two per month, bulk phishing decreased by 99% and now represents under 1% of traffic—improvements the IT team calls a game‑changer, supported by responsive Mimecast customer care.
