Case Study: The Sheffield College achieves a 20% reduction in malicious Office 365 emails with Barracuda Networks Total Email Protection

UK college cuts malicious Office 365 emails by 20% after comprehensive email security refresh

The Sheffield College, a further education institution in northern England serving about 15,000 students with a hybrid on‑premises and cloud IT estate, was facing a rise in targeted attacks (ransomware, BEC and personalized phishing) and an inflexible email filter that lacked modern AI capabilities and easy administrative control.

After a short trial the college deployed Barracuda Total Email Protection with cloud‑to‑cloud backup; the team reports an estimated 20% reduction in spam and malicious mail (dropping from ~30% to ~10%), faster incident response (malicious messages can be found and removed in seconds), simpler day‑to‑day management from a single console and improved support, with ongoing fine‑tuning and adoption of additional security awareness tools under consideration.
