Case Study: Sapphire Utility Solutions achieves robust email protection and higher phishing awareness with Barracuda Networks

Transforming employees into a formidable line of cyber-defense at UK utilities provider

Sapphire Utility Solutions is a fast‑growing UK utilities provider founded in 2013 that now employs about 1,000 people, roughly 70% of whom are mobile field workers. Rapid growth and widespread use of personal webmail left the company with low phishing awareness and increased exposure to email threats, including targeted business‑email‑compromise attacks on senior management, during a migration to Microsoft 365.

To address this, Sapphire deployed Barracuda Email Protection—combining advanced threat filtering, AI‑driven impersonation protection, cloud backup, DLP, security awareness training and rapid incident response. The result: virtually malware‑free operations for 18+ months, lower phishing click‑through rates, more employee reporting of suspicious messages, faster remediation of incidents and greater visibility of IT’s role in protecting the business.
