Case Study: Leading Retail Organization achieves 10% reduction in malicious emails with Cofense Validator

Retailer Reduces Malicious Emails in Inboxes by 10% Through Optimization of Email Security

Leading Retail Organization, a large electronics and building materials retailer with ~27,000 employees, was investing heavily in email security yet continued to see significant threats reach employee inboxes. The organization engaged Cofense and used Cofense Validator (with threat feeds from Cofense Intelligence) to test and benchmark multiple configurations across their Microsoft EOP and Cisco IronPort email controls.

Cofense ran a three-week, side-by-side validation using four mailbox profiles and real active threats, uncovering configuration gaps (including IronPort IPs on an EOP allow list) and guiding changes so both IronPort and Microsoft would scan incoming mail. After implementing Cofense’s recommended configuration updates, reported malicious emails dropped by roughly 10% in the month immediately following the changes, showing immediate and measurable improvement to the retailer’s email security posture.
