About DMARC Defender

Stuart, founder of DMARC Defender

Why I Built DMARC Defender

I found the existing DMARC tools to be a frustrating experience. Vendors required a mandatory sales calls, feature gating (SSO tax), and a lack of transparency on pricing.

I decided instead just to create my own tool. DMARC Defender is designed to be simple, affordable, and honest.

Background

I have about 20 years of software engineering and security experience. I'm also the founder of csper.io . 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. My goal is to empower individuals and organizations to take control of their email security without the hassle or hidden costs.
