Case Study: Well Pharmacy achieves reduced email data loss and greater efficiency with KnowBe4 Prevent

Well Pharmacy Uses KnowBe4 Prevent to Stop Email Data Loss in Microsoft 365

Well Pharmacy, the largest independent pharmacy chain in the UK with over 740 pharmacies, faced a growing risk of accidental data loss as staff regularly emailed sensitive patient and corporate information. To reduce human error in Microsoft 365 email, Well Pharmacy partnered with KnowBe4 and piloted then adopted KnowBe4 Prevent (building on prior use of KnowBe4 Protect) as an intelligent email DLP solution.

KnowBe4 deployed Prevent’s machine-learning checks and real-time prompts—initially to high‑risk users, then to all office-based staff—so users are warned and can correct mistakes before sending. The result: Well moved from reactive to proactive email security, reported zero recall requests since deployment, saved security team time triaging incidents, improved employee efficiency and awareness, and achieved quick, low‑friction rollout and immediate value with KnowBe4’s support.
