How Mr Price Group curbed spoofing with a DMARC reject policy

The challenge

As threats evolved globally and Mr Price Group expanded its digital footprint, securing its email environment became more challenging. Multiple brands, domains, and external platforms across different countries were generating large volumes of legitimate traffic. The growth and popularity of the group sparked interest in the threat actor community, resulting in numerous spoofing and email impersonation attempts.

This created several challenges:

• Limited visibility across sending sources
• Increased impersonation attempts
• Growing exposure to cyberthreats
• Deliverability and blacklisting concerns
• Damaged brand trust and confidence

Requirements

Mr Price Group needed a solution that would provide:

1. Full visibility of all email-sending sources, with correct authentication for every legitimate system across all domains
2. Expert guidance to reach a DMARC reject policy, with ongoing support and simplified DNS management
3. Stronger protection against domain spoofing and a safe, confident path to achieving a DMARC reject policy without disruption

Results

• Domains fully protected with a DMARC reject policy
• Improved deliverability through correct authentication
• Full visibility and control for IT and security teams
• Increased brand trust and customer security
• Ensured continuous protection via ongoing monitoring

“The implementation of Sendmarc’s DMARC solution was a game-changer, giving us the visibility and control needed to move swiftly to enforcement, blocking volumes of malicious phishing and spoofing emails that threatened our brand reputation and operations.”
