Case Study: Macmillan Cancer Support eliminates financial fraud and safeguards its reputation with Barracuda Networks' email and firewall solutions

Safeguarding Macmillan Cancer Support from financial and reputational damage

Macmillan Cancer Support, one of Britain’s largest charities with about 1,500 staff and roughly 3,000 inboxes, needed to protect sensitive donor, patient and volunteer information while operating under tight budget constraints. The organisation faced escalating business email compromise (BEC) attacks that allowed fraud and threatened its reputation after malicious messages bypassed its incumbent email provider.

Macmillan implemented Barracuda Web Application Firewall, CloudGen Firewall and Barracuda Email Protection—selected for cost, usability and support—leveraging AI-powered impersonation detection and automated incident response to remove threats quickly. Since Q1 2024 the charity’s financial fraud losses have fallen from £37,000 to £0, with improved email security, faster remediation and continued vendor support as it moves toward a Zero Trust model.
