About DMARC Defender
Why I Built DMARC Defender
I found the existing DMARC tools to be a frustrating experience. I wanted something simple and fair, but instead found mandatory sales calls, feature gating (SSO tax), and a lack of transparency on pricing.
So I built the tool I wished existed. DMARC Defender is designed to be simple, affordable, and honest.
Background
I have about 20 years of software engineering and security experience. I also founded csper.io in 2019, which has a very similar story to DMARC Defender. In my free time I play Capture The Flag competitions (YouTube channel). Previously I worked as a security engineer at organizations including Yahoo! and MongoDB.
Philosophy
I believe DMARC should be simple, affordable, and honest. I promise transparent pricing and zero sales calls. My goal is to empower individuals and organizations to take control of their email security without the hassle.
