This case study looks at a non-profit organization specializing in the administration of exchange visitor programs on behalf of the U.S. Government. For more than 50 years they have been responsible for facilitating exchange programs between the U.S. and over 60 countries requiring them to send over 3 million emails each year.

Uncovering services and instantly verifying SPF alignment

With only a basic DMARC reporting tool at the time, the organization knew they were over the SPF lookup limit and that their SPF alignment needed work, but had no guidance from the tool on how to fix it. With different services using their email across the organization the challenge was to identify and secure all senders:

  1. Discovery

    The Chief Technology Officer (CTO) compared how “Unlike other DMARC reporting tools, OnDMARC offered an intuitive interface with clear insight into what’s aligned or not aligned for SPF for each service using our domain. This kept us on track and got the job done effectively”.

  2. Validation

    The team instantly verified configurations without having to wait 24 hours for changes to take effect in their DNS thanks to Investigate. The CTO commented, “This tool was fundamental. We used Investigate as proof to heads of department that we could safely implement DMARC and SPF without blocking any legitimate business emails”.

  3. Ongoing protection

    After securing their domain with OnDMARC, a 30- day report revealed that of the 566,395 emails sent from their domain, 68% were fake. The CTO acknowledged that “due to the nature of what we do, we’re a high-risk industry for phishing scams” but reports comfortingly confirmed that all unauthorized emails were blocked from delivery.
