Case Study: Piedmont Natural Gas of Charlotte achieves $30K savings and 99%+ spam reduction with Guardian Digital EnGarde Cloud Email Security

Cost-Effective Phishing, Managed Email Security for Energy Services Provider

Piedmont Natural Gas of Charlotte, a large Southeast energy and services provider serving over 690,000 customers, needed a secure, cost‑effective email solution to address limited budget, a complex user environment, and rising spam, malware and phishing risks. Senior Network Security Engineer John Cahill selected Guardian Digital and its EnGarde Cloud Email Security to establish a secure Internet presence for corporate email functions.

Guardian Digital implemented EnGarde Cloud Email Security as a managed, scalable cloud service (Piedmont purchased four cloud systems for required redundancy) with premium support and monitoring. The deployment reduced spam by >99%, saved Piedmont $30k compared with alternatives, improved network security and user productivity, and provided ongoing monitoring, updates and stronger phishing/malware protection.
