Case Study: Nationwide Specialist Services achieves near-elimination of phishing and financial fraud with Barracuda Networks' AI-powered email protection

NSS Group enhances protection from financial fraud and phishing with AI-powered intelligence

Nationwide Specialist Services (NSS) Group is a UK cleaning and maintenance firm with about 600 users—roughly 80% mobile—and grew 20% during the pandemic. That success brought a surge in sophisticated phishing and targeted business email compromise (BEC) attacks, and NSS’s existing email security was letting malicious messages through and creating too many false positives, putting strain on the small IT team.

NSS deployed Barracuda Sentinel, Barracuda Essentials and Barracuda Forensics & Incident Response with a quick cloud setup, and the tools now block about 300–400 malicious emails per day. The solution eliminated most inbound threats, improved user awareness, saved IT administrators 2–3 hours per week, and in 20 months triggered serious incident response only once—stopping a campaign within minutes—giving NSS a much more secure foundation for continued growth.
